    Introduction Syphilis remains a major public health problem in sub-Saharan Africa, including Burkina Faso. However, few published data are available on the prevalence of syphilis in the general population. This study had two main objectives: to determine the seroprevalence of syphilis in a cohort of 37,210 first time blood donors and to study socio-demographic factors associated with the risk of infection by Treponema pallidum. Methods Antibodies to Treponema pallidum were screened for, by using Reagin Rapid Test (RPR) and their presence was confirmed by treponema pallidum haemagglutination test (TPHA). Results The overall seroprevalence of syphilis was 1.5% among first time blood donors and was significantly different between centers (p <0.001). The infection was significantly higher in men than women among blood donors in Ouagadougou and Fada N′gourma (P = 0.001 and P = 0.034). The overall seroprevalence of syphilis among blood donors was not associated with either age group or HIV status. In contrast, a significantly high seroprevalence of syphilis was observed in blood donors with HBsAg (P = 0.014) and anti-HCV (P = 0.007) positive. Conclusion Our report shows a low seroprevalence of syphilis in the representative sample of the population of Burkina Faso. The seroprevalence of syphilis remains unequally distributed between urban and rural areas and was not associated with HIV infection. PMID:24711869

    We undertook a comparative analysis of (peri-)urban livestock production strategies across three West African cities. Using a semi-structured questionnaire, livestock-keeping households (HH) were interviewed in Kano/Nigeria (84 HH), Bobo Dioulasso/Burkina Faso (63 HH) and Sikasso/Mali (63 HH). Questions covered livestock species kept, herd sizes and structure, feeds used, manure management, livestock marketing and production constraints. Sheep and goats dominated (p < 0.001) in Kano (76 and 75 % of HH) compared to Bobo Dioulasso (48 and 40 %) and Sikasso (28 and 40 %), while cattle and poultry were more frequent (p < 0.001) in Bobo Dioulasso (82 and 69 % of HH) and Sikasso (65 and 79 %) than in Kano (29 and 20 %). Across cities, ruminant feeding relied on grazing and homestead supplementation with fresh grasses, crop residues, cereal brans and cottonseed cake; cereal grains and brans were major ingredients of poultry feeds. Cattle and sheep fetched highest prices in Kano, unit prices for goats and chicken were highest in Sikasso. Across cities there was little association of gardens and livestock, whereas field cropping and livestock were integrated. There was no relation between the education of the HH head and the adoption of improved management practices (p > 0.05), but the proportion of HH heads with a long-term experience in UPA activities was higher in Kano and in Bobo Dioulasso than in Sikasso (p < 0.001). We therefore postulate that the high illiteracy rate among (peri-)urban livestock keepers in West Africa does not threaten the acceptance of improved technologies and innovations supporting the sustainability of their livestock production.

    Background This methodological article is based on a health policy research project conducted in Burkina Faso (West Africa). Concept mapping (CM) was used as a research method to understand the local views of equity among stakeholders, who were concerned by the health policy under consideration. While this technique has been used in North America and elsewhere, to our knowledge it has not yet been applied in Africa in any vernacular language. Its application raises many issues and certain methodological limitations. Our objective in this article is to present its use in this particular context, and to share a number of methodological observations on the subject. Methods Two CMs were done among two different groups of local stakeholders following four steps: generating ideas, structuring the ideas, computing maps using multidimensional scaling and cluster analysis methods, and interpreting maps. Fifteen nurses were invited to take part in the study, all of whom had undergone training on health policies. Of these, nine nurses (60%) ultimately attended the two-day meeting, conducted in French. Of 45 members of village health committees who attended training on health policies, only eight were literate in the local language (Moore). Seven of these (88%) came to the meeting. Results The local perception of equity seems close to the egalitarian model. The actors are not ready to compromise social stability and peace for the benefit of the worst-off. The discussion on the methodological limitations of CM raises the limitations of asking a single question in Moore and the challenge of translating a concept as complex as equity. While the translation of equity into Moore undoubtedly oriented the discussions toward social relations, we believe that, in the context of this study, the open-ended question concerning social justice has a threefold relevance. At the same time, those limitations were transformed into strengths. We understand that it was essential to resort to the

    Objective. This study aimed to investigate the association between three polymorphisms of renin-angiotensin system and the essential hypertension in the population of Burkina Faso. Methodology. This was a case-control study including 202 cases and 204 matched controls subjects. The polymorphisms were identified by a classical and a real-time PCR. Results. The AGT 235M/T and AT1R 1166A/C polymorphisms were not associated with the hypertension while the genotype frequencies of the ACE I/D polymorphism between patients and controls (DD: 66.83% and 35.78%, ID: 28.22% and 50.98%, II: 4.95% and 13.24%, resp.) were significantly different (p < 10−4). The genotype DD of ACE gene (OR = 3.40, p < 0.0001), the increasing age (OR = 3.83, p < 0.0001), obesity (OR = 4.84, p < 0.0001), dyslipidemia (OR = 3.43, p = 0.021), and alcohol intake (OR = 2.76, p < 0.0001) were identified as the independent risk factors for hypertension by multinomial logistic regression. Conclusion. The DD genotype of the ACE gene is involved in susceptibility to hypertension. Further investigations are needed to better monitor and provide individualized care for hypertensive patients. PMID:26351579

    Burkina Faso is part of the Sahel-Sudan climatic zone south of the Sahara Desert. The rainfall of the region is characterized by extreme seasonal and annual temporal and spatial variability. Soils are generally of low fertility. The major livelihood activity in Burkina Faso, one of the lowest ranked countries in the world in the Human Development Index where 80 percent of the population rely on subsistence farming, is rainfed cultivation of cereal crops. Cotton is the dominant export crop and is mostly grown in the southwest. Livestock management is an important complement to farm activities, especially in the Sahelian zone. There are several major rivers flowing through the region and many ephemeral streams. Surface water resources are becoming more important to Burkina Faso as it tries to improve food security and water supplies, and increase energy production. One of the major opportunities to improve livelihoods in the region has been improvements in seasonal rainfall forecasting based upon global sea surface temperatures. In the past decade, the generation and use of forecasts in Burkina Faso has evolved from the nation just receiving forecasts almost as an after thought from USA and European meteorological services to the Burkina Faso Meteorological Services generating their own forecasts with support from these services. There is now also more focused international research on improving the forecasts for this region. The use of stochastic decision support tools (DST) that combine the seasonal forecasts with hydrologic and crop models, land conditions, and information on farmer and policy maker goals could improve both rainfed and irrigated agricultural systems. Their implementation requires overcoming many technical and socio-economic challenges. Examples include forecasting the start and end of rains, dissemination and explanation of forecasts, streamflow forecasting in data scarce regions, possible different incentives for subsistence and cash crop farmers

    When conducting research in different cultural settings, assessing measurement equivalence is of prime importance to determine if constructs and scores can be compared across groups. Structural equivalence implies that constructs have the same meaning across groups, metric equivalence implies that the metric of the scales remains stable across groups, and full scale or scalar equivalence implies that the origin of the scales is the same across groups. Several studies have observed that the structure underlying both normal personality and personality disorders (PDs) is stable across cultures. Most of this cross-cultural research was conducted in Western and Asian cultures. In Africa, the few studies were conducted with well-educated participants using French or English instruments. No research was conducted in Africa with less privileged or preliterate samples. The aim of this research was to study the structure and expression of normal and abnormal personality in an urban and a rural sample in Burkina Faso. The sample included 1,750 participants, with a sub-sample from the urban area of Ouagadougou (n = 1,249) and another sub-sample from a rural village, Soumiaga (n = 501). Most participants answered an interview consisting of a Mooré language adaptation of the Revised NEO Personality Inventory and of the International Personality Disorders Examination. Mooré is the language of the Mossi ethnic group, and the most frequently spoken local language in Burkina Faso. A sub-sample completed the same self-report instruments in French. Demographic variables only had a small impact on normal and abnormal personality traits mean levels. The structure underlying normal personality was unstable across regions and languages, illustrating that translating a complex psychological inventory into a native African language is a very difficult task. The structure underlying abnormal personality and the metric of PDs scales were stable across regions. As scalar equivalence

    We report the results of a cross-sectional study carried out in 1995-96 on anaemia in pregnant women who were attending two antenatal clinics in Bobo-Dioulasso, Burkina Faso, as part of a research programme including a clinical trial of zidovudine (ZDV) in pregnancy (ANRS 049 Clinical Trial). For women infected with human immunodeficiency virus (HIV) in Africa, anaemia is of particular concern when considering the use of ZDV to decrease mother-to-child transmission of HIV. The objectives were to determine the prevalence of and risk factors for maternal anaemia in the study population, and the effect of HIV infection on the severity of maternal anaemia. HIV counselling and testing were offered to all women, and haemograms were determined for those women who consented to serological testing. Haemoglobin (Hb) levels were available for 2308 of the 2667 women who accepted HIV testing. The prevalence of HIV infection was 9.7% (95% confidence interval (CI): 8.6-10.8%). The overall prevalence of anaemia during pregnancy (Hb level < 11 g/dl) was 66% (95% CI: 64-68%). The prevalence of mild (10 g/dl < or = Hb < 11 g/dl), moderate (7 g/dl < or = Hb < 10 g/dl) and severe (Hb < 7 g/dl) anaemia was 30.8%, 33.5% and 1.7%, respectively. The prevalence of anaemia was 78.4% in HIV-infected women versus 64.7% in HIV-seronegative women (P < 0.001). Although the relative risk of HIV-seropositivity increased with the severity of anaemia, no significant association was found between degree of anaemia and HIV serostatus among the study women with anaemia. Logistic regression analysis showed that anaemia was significantly and independently related to HIV infection, advanced gestational age, and low socioeconomic status. This study confirms the high prevalence of anaemia during pregnancy in Burkina Faso. Antenatal care in this population must include iron supplementation. Although HIV-infected women had a higher prevalence of anaemia, severe anaemia was infrequent, possibly because few

    This study aims at evaluating the prevalence and density of haemoparasites in a native population of immature and adult male and female birds of Burkina Faso. Protists from the orders Eucoccidiorida, Kinetoplastida, as well as microfilaria were found. During the period from the 27th to the 29th of November 2003, we trapped 110 birds: on 101 sampled birds, 47 harboured blood parasites, with an overall prevalence of infection of 46.5%; 15 birds (14.8%) harboured mixed infections. Haemoproteus (prevalence of infection 30.7%), Plasmodium (13.9%), Trypanosoma (10.9%), microfilaria (8.9%) and Leucocytozoon (5.9%) were most frequently recorded. Occurrence of blood parasites was very high in comparison to that seen in birds from other areas of Africa.

    Burkina Faso, through the works of many teams of the OCCGE based in Bobo-Dioulasso, has signi-ficant data on several tropical endemics of which schistosomiasis. With the complementary works, it appears to be possible to establish a distribution of the schistosomiasis which reveals its importance. It will be the first stage of the planned national control program. The parasitologic data-gathering which covers the period of 1951 to 2000, used all the standard techniques. It is about Kato-Kartz and MIF for the intestinal schistosomiasis, centrifugation, filtration, serology reagent strips, macroscopy of urines and echography of the urinary system for the urinary schistosomiasis. All the eleven medical areas of the country have many sites submitted to parasitologic investigation. As regard the distribution of the two parasites involved with man (Schistosoma haematobium and S. mansoni), the data of prevalence (1% to 100%) and their distribution confirm their endemicity and the focal transmission. S. mansoni is located in eight medical areas particularly in the South and the West. S. haematobium is present in all the eleven medical areas of the country. In hydraulic planning as Sourou where the prevalences went from 23% to 70% for S. haematobium and from 0% to 69% for S. mansoni between 1987 and 1998. The situation requires a continuous monitoring. The spatial distribution of the six species of intermediate hosts shows that Bulinus truncatus and B. senegalensis Soudano-Sahelian species are present in all the ecological zones. B. globosus and Biomphalaria pfeifferi meet preferentially in the southern half of the country which reinforces the observation according to which the 14th northern parallel is often considered as the limit of septentrional extension of these two species. The other species Bulinus forskalii and B umbilicatus could have preference areas. All the species show a certain affinity with a type of biotope. The rarity and temporary aquatic systems lead to a

    Despite great progress in schistosomiasis control over the past decade in Burkina Faso, this disease remains a public health problem. This study analyzes parasitologic data from investigations of Schistosoma haematobium, S. mansoni, and mollusks. The prevalence rate of S. haematobium varies from 3.3% to 50.4%; that for S. mansoni (tested only in the western part of the country) from 3.3% to 39.1%. Prevalence rates are higher in school-aged boys than girls, but the reverse is true among adults. Studies of mussels showed the presence of Biomphalaria pfeifferi, Bulinus truncatus, Bulinus senegalensis and Bulinus globosus in these areas. Our results indicate that behavioral factors as well as the dynamics and the distribution of the intermediate mollusks play a major role in the persistence of the disease.

    The prevalence of Toxoplasma gondii in free-ranging chickens (Gallus domesticus) is a good indicator of the prevalence of T. gondii oocysts in the soil because chickens feed from the ground. In the present study, prevalence of T. gondii in chickens from Democratic Republic of Congo, Mali, Burkina Faso, and Kenya is reported. The prevalence of T. gondii antibodies in sera of 50 free-range chickens from Congo was 50% based on the modified agglutination test (MAT); antibody titers were 1:5 in 7, 1:10 in 7, 1:20 in 6, 1:40 in 1, and 1:160 or more in 4 chickens. Hearts, pectoral muscles, and brains of 11 chickens with titers of 1:20 or more were bioassayed individually in mice; T. gondii was isolated from 9, from the hearts of 9, brains of 3, and muscles of 3 chickens. Tissues of each of the 14 chickens with titers of 1:5 or 1:10 were pooled and bioassayed in mice; T. gondii was isolated from 1 chicken with a titer of 1:10. Tissues from the remaining 25 seronegative chickens were pooled and fed to 1 T. gondii-free cat. Feces of the cat were examined for oocysts, but none was seen. The results indicate that T. gondii localizes in the hearts more often than in other tissues of naturally infected chickens. Genotyping of these 10 isolates using the SAG2 locus indicated that 8 were isolates were type III, 1 was type II, and 1 was type I. Two isolates (1 type I and 1 type III) were virulent for mice. Toxoplasma gondii was isolated by mouse bioassay from a pool of brains and hearts of 5 of 48 chickens from Mali and 1 of 40 chickens from Burkina Faso; all 6 isolates were avirulent for mice. Genetically, 4 isolates were type III and 2 were type II. Sera were not available from chickens from Mali and Burkina Faso. Toxoplasma gondii antibodies (MAT 100 or more) were found in 4 of 30 chickens from Kenya, and T. gondii was isolated from the brain of 1 of 4 seropositive chickens; this strain was avirulent for mice and was type II. This is the first report on isolation and genotyping

    To gain insight into the dry season survival strategies of Anopheles gambiae s.l., a new contained semi-field system was developed and used for the first time in Burkina Faso, West Africa. The system consisted of a screened greenhouse within which the local environment was reproduced, including all ecological requirements for mosquito development cycle completion. The system was seeded with the progenies of female Anopheles gambiae, Anopheles coluzzii, and Anopheles arabiensis collected in the vicinity of the greenhouse during the rainy season. After successful establishment in the semi-field system, mosquito populations were monitored over a 1-yr period by regular surveys of larval and adult specimens. We provided evidence for the persistence of adult mosquitoes throughout the dry season, in the absence of any suitable larval development site. During the hot and dry periods, adult insects were observed in artificial shelters (clay pots, building blocks, and dark corners). The mosquito population rapidly built up with the return of the rainy season in the area, when artificial breeding sites were refilled in the enclosure. However, only An. coluzzii and, later, An. arabiensis were detected in the subsequent rainy season, whereas no An. gambiae specimen was found. Our findings suggest that An. coluzzii and An. arabiensis may be able to aestivate throughout the dry season in Southwestern Burkina Faso, whereas An. gambiae might adopt a different dry-season survival strategy, such as long-distance re-colonization from distant locations. These results may have important implications for malaria control through targeted vector control interventions. PMID:26576935

    Despite a considerable knowledge of the significant role of termites in the global methane budget, very little is known about their contribution to the global nitrous oxide (N2O) budget. Release of N2O from termite (Cubitermes fungifaber) mounds was measured at a natural savanna site in the southwest of Burkina Faso from May to September 2006. Termite N2O emissions were around 20 μg N2O-N m-2 h-1 at the end of the dry season, and up to two orders of magnitude higher than N2O emissions from the surrounding termite-free soil after the onset of the rainy season. The average N2O emission rate from termite mounds during the observation period was 204 μg N2O-N m-2 h-1, and termite mounds contributed 3.0% to total N2O emissions from this savanna ecosystem. However, in other tropical terrestrial ecosystems with other termite species and/or higher termite density this share might be significantly higher.

    Local knowledge could form an effective channel and base through which climate change adaptation and mitigation can be realized. This paper uses the context of savannas ecosystem services in Burkina Faso to examine local knowledge and perspectives on the changing trends in vulnerability and adaptation to climate change. The survey targeted farmers, traditional authorities and administrators at the local government level. Semi-structured questionnaires were employed for one-on-one interviews and focused group discussions for data collection. Descriptive statistics and explanatory factor analysis were used to analyze the collected data. A total of 230 farmers, 6 traditional authorities and 5 administrators belonging to 32 villages were interviewed. Most of local people (95.1-96.7%) believe that climate change is occurring, and cited general increases in average temperatures, fluctuating rainfall regimes and extended drought periods as some of their observations. They explain the increasing changes and vulnerability of savannas ecosystems through the longer time spent and distance covered to collect medicinal plants and forest food; decreasing productivity and availability of fodder, fuel wood, forest food and medicinal plant, changing uses of forest food and medicinal plant species. The views of farmers were generally shared by the traditional authorities and administrators. Adaptation actions employed by local communities are tree planting, protection of forestry resources, migration, awareness raising, conservation of soil and water resources.

    The mosquito, Anopheles coluzzii is a major vector of human malaria in Africa with widespread distribution throughout the continent. The species hence populates a wide range of environments in contrasted ecological settings often exposed to strong seasonal fluctuations. In the dry savannahs of West Africa, this mosquito population dynamics closely follows the pace of surface water availability: the species pullulates during the rainy season and is able to reproduce throughout the dry season in areas where permanent water bodies are available for breeding. The impact of such environmental fluctuation on mosquito development and the phenotypic quality of emerging adults has however not been addressed in details. Here, we examined and compared phenotypic changes in the duration of pre-imaginal development, body dry mass at emergence and wing size, shape and surface area in young adult females An. coluzzii originated from five distinct geographic locations when they are reared in two contrasting conditions mimicking those experienced by mosquitoes during the rainy season (RS) and at the onset of the dry season (ODS) in Burkina Faso (West Africa). Our results demonstrated strong phenotypic plasticity in all traits, with differences in the magnitude and direction of changes between RS and ODS depending upon the geographic origin, hence the genetic background of the mosquito populations. Highest heterogeneity within population was observed in Bama, where large irrigation schemes allow year-round mosquito breeding. Further studies are needed to explore the adaptive value of such phenotypic plasticity and its relevance for local adaptation in An. coluzzii.

    Despite efforts expended over recent decades, there is a persistent gap between the production of scientific evidence and its use. This is mainly due to the difficulty of bringing such knowledge to health workers and decision-makers so that it can inform practices and decisions on a timely basis. One strategy for transferring knowledge to potential users, that is, gaining increasing legitimacy, is knowledge brokering (KB), effectiveness of which in certain conditions has been demonstrated through empirical research. However, little is known about how to implement such a strategy, especially in the African context. The KB program presented here is aimed specifically at narrowing the gap by making scientific knowledge available to users with the potential to improve health-related practices and decision making in Burkina Faso. The program involves Canadian and African researchers, a knowledge broker, health practitioners, and policy-makers. This article presents the collaborative development of the KB strategy and the evaluation of its implementation at year 1. The KB strategy was developed in stages, beginning with a scoping study to ensure the most recent studies were considered. Two one-day workshops were then conducted to explore the problem of low research use and to adapt the strategy to the Burkinabè context. Based on these workshops, the KB program was developed and brokers were recruited and trained. Evaluation of the program's implementation after the first year showed that: 1) the preparatory activities were greatly appreciated by participants, and most considered the content useful for their work; 2) the broker had carried out his role in accordance with the logic model; and 3) this role was seen as important by the participants targeted by the activities and outputs. Participants made suggestions for program improvements in subsequent years, stressing particularly the need to involve decision-makers at the central level.

This is mainly due to the difficulty of bringing such knowledge to health workers and decision-makers so that it can inform practices and decisions on a timely basis. One strategy for transferring knowledge to potential users, that is, gaining increasing legitimacy, is knowledge brokering (KB), effectiveness of which in certain conditions has been demonstrated through empirical research. However, little is known about how to implement such a strategy, especially in the African context. The KB program presented here is aimed specifically at narrowing the gap by making scientific knowledge available to users with the potential to improve health-related practices and decision making in Burkina Faso. The program involves Canadian and African researchers, a knowledge broker, health practitioners, and policy-makers. This article presents the collaborative development of the KB strategy and the evaluation of its implementation at year 1. The KB strategy was developed in stages, beginning with a scoping study to ensure the most recent studies were considered. Two one-day workshops were then conducted to explore the problem of low research use and to adapt the strategy to the Burkinabè context. Based on these workshops, the KB program was developed and brokers were recruited and trained. Evaluation of the program's implementation after the first year showed that: 1) the preparatory activities were greatly appreciated by participants, and most considered the content useful for their work; 2) the broker had carried out his role in accordance with the logic model; and 3) this role was seen as important by the participants targeted by the activities and outputs. Participants made suggestions for program improvements in subsequent years, stressing particularly the need to involve decision-makers at the central level. PMID:25630708

    Burkina Faso is among the largest recipients of development aid in West Africa. The new aid terminology emphasizes partnership and a sectoral approach. Yet, recent research suggests more continuity than change in the aid relationship. Projects persist. Funding and technical assistance agencies cooperate more but adhere to their interests,…

    African cities are presently facing the combined impacts of growing urbanization and climate change. In several instances; providing safe drinking water for all is still a challenge, especially for cities located on basement aquifers, were groundwater is scarce. Here we assess the effects of climate change and land use change on groundwater amount and quality in the main city of Ouagadougou (Burkina Faso) taking advantage of the CIEH borehole, where a mostly continuous record lasts since 1978. This record spans most of the Great African Drought (1970-1990) and recovery from the Drought since the 2000s. A piezometric network of 14 wells and boreholes was setup around the CIEH borehole and monitored during the 2013-2014 hydrologic year. The piezometric network spans an old settlement, the Ouagadougou University, a vegetable gardening area and a natural forested area. Water balance estimates are provided by a 1D box model. The study area, although it lies partly on an old settlement in Ouagadougou and on the University area, presents a rather uniform runoff coefficient of 22% and ET amounting to 80-90 % of rainfall, which usually characterizes natural areas. It is suspected that the almost absence of asphalted surfaces, the presence of trees and flow of rainwater from roofs toward bare soils or sumps could be responsible of this budget. However, the two wells located in the forested Bangr Weogo recreational area are characterized by almost no runoff and a nearly 100 % ET. While drinking water can be pumped in several places in the city of Ouagadougou, chemical major analyses show that two mechanisms impact groundwater quality during the rainy season: (i) rise of the water table at pit latrine level, mainly in old settlements, and entrainment of harmful substances from soil to the aquifer in gardening area near some artisan activities. The CIEH borehole is not fully representative of its neighboring area since (i) it lies in a piezometric low, (ii) it presents the

    In spite of great progress in schistosomiasis control during the last decade in Burkina Faso, this disease remains a public health concern in the country. Indeed, our study consisted of the analysis of parasitological data related to Schistosoma haematobium and Schistosoma mansoni and in malacological investigations. The prevalence rate of Schistosoma haematobium varies from 3.3% to 50.4% and from 3.3% to 39.1% for Schistosoma mansoni, but only in the western part of Burkina Faso. Schoolboys are more infested than girls, but the phenomenon is reversed in adults. Biomphalaria pfeifferi, Bulinus truncatus, Bulinus senegalensis and Bulinus globosus were collected during this study. Thus, the behavioral factors as well as the dynamics and the distribution of the intermediate mollusks play a major role in the persistence of the disease.

    In West Africa, health system funding rarely involves cross-subsidization among population segments. In some countries, a few community-based or professional health insurance programs are present, but coverage is very low. The financial principles underlying universal health coverage (UHC) sustainability and solidarity are threefold: 1) anticipation of potential health risks; 2) risk sharing and; 3) socio-economic status solidarity. In Burkina Faso, where decision-makers are favorable to national health insurance, we measured endorsement of these principles and discerned which management configurations would achieve the greatest adherence. We used a sequential exploratory design. In a qualitative step (9 interviews, 12 focus groups), we adapted an instrument proposed by Goudge et al. (2012) to the local context and addressed desirability bias. Then, in a quantitative step (1255 respondents from the general population), we measured endorsement. Thematic analysis (qualitative) and logistic regressions (quantitative) were used. High levels of endorsement were found for each principle. Actual practices showed that anticipation and risk sharing were not only intentions. Preferences were given to solidarity between socio-economic status (SES) levels and progressivity. Although respondents seemed to prefer the national level for implementation, their current solidarity practices were mainly focused on close family. Thus, contribution levels should be set so that the entire family benefits from healthcare. Some critical conditions must be met to make UHC financial principles a reality through health insurance in Burkina Faso: trust, fair and mandatory contributions, and education. PMID:26803656

    Shigatoxigenic Escherichia coli (STEC) cause serious foodborne infections that lead to diarrheal disease and sequelae worldwide. In Burkina Faso, West Africa, STEC strains from environmental and human sources have not been isolated and characterized before. In this study, 21 STEC strains were isolated from food samples of animal origin and human feces using colony hybridization of the Shiga toxin gene stx. The STEC strains belonged to 15 different serotypes, including O43:H2, O8:H(-), and O2:H2. All strains were positive for stx(1) and 10 also for stx(2). The most common stx(1) subtype was stx(1a), and the most common stx(2) subtype was stx(2b). In five strains, stx(2) subtypes stx(2a) and/or stx(2c), which were previously associated with hemolytic uremic syndrome, were present. Some of the strains possessed the gene saa, encoding autoagglutinating adhesin. None of the strains possessed the gene eae, encoding intimin. Two STEC strains carried also an enterotoxigenic E. coli-associated gene estIa, encoding heat-stable enterotoxin. The STEC isolated from food in Burkina Faso are potentially pathogenic for humans based on the virulence gene combinations that they possess and phenotypes that they express. PMID:23134285

    Land degradation is an environmental problem which weakens agro-silvo-pastoral productivity in Sub-Saharan Africa. The most common manifestation of land degradation is the appearance of denuded land. We carried out an experiment to test the effect of three soil and water conservation techniques on survival and growth of Jatropha curcas seedlings transplanted onto two completely denuded lands in the Sahelian and Sudanian zones of Burkina Faso. We implemented an experimental design with three replicates per restoration technique. A total of 174 seedlings were planted in each study site. The results showed that soil water content varied according to the restoration technique used (df = 2; F = 53.21; p < 0.00) as well as according to study site (df = 1; F = 74.48; p < 0.00). Soil water content was significantly lower in the Sahel than in the Sudanian zone. Seedling survival rate varied significantly according to technique used (df = 2; F = 8.91; p = 0.000) and study site (df = 1; F = 9.74; p = 0.003). Survival rate, diameter and seedling height were highest at the Sudanian site. At the Sahelian site, all seedlings died two years after establishment. These results suggest that Jatropha curcas is unsuited to denuded land in the Sahelian zone. Most of the plants died in the Sahel between April and May, which is the peak of the dry season; this may be an indication that Jatropha may not be as drought-resistant as suggested by the prolific literature which has reported on diverse claims surrounding this plant.

    With the "green economy" being promoted as a path to sustainable development and food security within the African continent, the influx of agricultural land is proliferating at a rapid pace often replacing natural savannah forests. Where agriculture is primarily rainfed, the possible adverse impacts of agricultural land influx on rainfall occurrences in water-limited areas such as West Africa warrant attention. Using field observations complemented by model calculations in southeastern Burkina Faso, the main causes of a 10-30% suppressed daytime rainfall recorded over agricultural fields when referenced to natural savannah forests are examined. Measurements and model runs reveal that the crossing of the mixed layer height and lifting condensation levels, a necessary condition for cloud formation and subsequent rainfall occurrence, was 30% more frequent above the natural savannah forest. This increase in crossing statistics was primarily explained by increases in measured sensible heat flux above the savannah forest rather than differences in lifting condensation heights.

    Cowpea, (Vigna unguiculata L. (Walp)) is an annual tropical grain legume. Often referred to as “poor man’s meat”, cowpea is one of the most important subsistence legumes cultivated in West Africa due to the high protein content of its seeds. However, African cowpea production can be seriously constrained by viral diseases that reduce yields. While twelve cowpea-infecting viruses have been reported from Africa, only three of these have so-far been reported from Burkina Faso. Here we use a virion-associated nucleic acids (VANA)-based metagenomics method to screen for the presence of cowpea viruses from plants collected from the three agro-climatic zones of Burkina Faso. Besides the three cowpea-infecting virus species which have previously been reported from Burkina Faso (Cowpea aphid borne mosaic virus [Family Potyviridae], the Blackeye cowpea mosaic virus—a strain of Bean common mosaic virus—[Family Potyviridae] and Cowpea mottle virus [Family Tombusviridae]) five additional viruses were identified: Southern cowpea mosaic virus (Sobemovirus genus), two previously uncharacterised polerovirus-like species (Family Luteoviridae), a previously uncharacterised tombusvirus-like species (Family Tombusviridae) and a previously uncharacterised mycotymovirus-like species (Family Tymoviridae). Overall, potyviruses were the most prevalent cowpea viruses (detected in 65.5% of samples) and the Southern Sudan zone of Burkina Faso was found to harbour the greatest degrees of viral diversity and viral prevalence. Partial genome sequences of the two novel polerovirus-like and tombusvirus-like species were determined and RT-PCR primers were designed for use in Burkina Faso to routinely detect all of these cowpea-associated viruses.

    The Volta Basin covers 400,000 km2 of the West-African savanna zone. Ghana lies downstream and contains 42% of the basin. Most of the upstream part of the basin lies in Burkina Faso (43% of total), and the remaining 15% lies in Mali, Côte d'Ivoire, Togo, and Benin. Average rainfall is 1000 mm per year of which around 9% or 36 km3 becomes available as runoff in the Volta River. Small variations in rainfall cause relatively large variations in runoff. The Volta Basin is undergoing rapid changes in land use and water resource development, mainly driven by the high population growth of 3% per year. However, different countries pursue economic development in different ways. At independence in 1957, Ghana's leaders saw industrialization as essential to development and electric power from the Volta Dam as central to that industrialization. In 1964, the Volta Dam was built and Ghana's economic growth in the mining, industrial, and service sectors has depended on the dam's hydropower ever since. In contrast, land-locked Burkina Faso has less industrial potential and seeks to develop through its agriculture, both for subsistence and export crops. Given the extremely unreliable rainfall, irrigation development is seen as the only way to increase agricultural production. In general, irrigation in Burkina Faso takes the form of many small scale, village-based schemes of which the downstream impact is difficult to gauge. A minor drought in 1997 and 1998 caused the level of Lake Volta to drop, resulting in widespread power outages. In the ensuing public discussion, hydraulic development in Burkina Faso was seen as one of the potential causes of the lack of water. No firm data were available to substantiate this claim. In fact, over-withdrawals in previous years combined with climate variability were more likely culprits. A recently initiated multi-disciplinary research project will be presented that seeks to provide a scientific basis on which future discussions between the two

    An entomological survey was carried out at 15 sites dispersed throughout the three eco-climatic regions of Burkina Faso (West Africa) in order to assess the current distribution and frequency of mutations that confer resistance to insecticides in An. gambiae s.l. populations in the country. Both knockdown (kdr) resistance mutation variants (L1014F and L1014S), that confer resistance to pyrethroid insecticides, were identified concomitant with the ace-1 G119S mutation confirming the presence of multiple resistance mechanisms in the An. gambiae complex in Burkina Faso. Compared to the last survey, the frequency of the L1014F kdr mutation appears to have remained largely stable and relatively high in all species. In contrast, the distribution and frequency of the L1014S mutation has increased significantly in An. gambiae s.l. across much of the country. Furthermore we report, for the first time, the identification of the ace.1 G116S mutation in An. arabiensis populations collected at 8 sites. This mutation, which confers resistance to organophosphate and carbamate insecticides, has been reported previously only in the An. gambiae S and M molecular forms. This finding is significant as organophosphates and carbamates are used in indoor residual sprays (IRS) to control malaria vectors as complementary strategies to the use of pyrethroid impregnated bednets. The occurrence of the three target-site resistance mutations in both An. gambiae molecular forms and now An. arabiensis has significant implications for the control of malaria vector populations in Burkina Faso and for resistance management strategies based on the rotation of insecticides with different modes of action.

    When Burkina Faso gained its independence, no one thought to act upon the various demographic variables with the aim of achieving certain specific, planned goals. It was necessary to wait until 1986 for the adoption of a planning policy and the abrogation of part of 1920 legislation on contraceptive distribution before the first signs of attitudinal change could be observed with regard to population concerns. Formerly confused with birth limiting policy, family planning is increasingly becoming an essential component of maternal and infant health. The author describes the evolution of population policies in Burkina Faso from independence, after the 1974 Bucharest conference on population, and up until now. Today, general population policy goals in Burkina Faso are in favor of whatever will improve quality of life and well-being across all social strata. This goal will only be attained through the establishment of better balance between population and available resources. It involves meeting the population¿s essential food, nutrition, health, education, and employment needs; raising the value of available human resources; lowering morbidity and mortality; improving women¿s status; improving the population¿s spatial distribution; managing the environment better; and accounting for demographic variables when establishing development goals. Burkina Faso therefore plans to pursue a comprehensive approach toward its population problems.

    Field-adaptable research methods for identifying Campylobacter sp., Yersinia sp. and other pathogenic and indicator bacteria were designed in Finland and tested in Burkina Faso. Several bacterial groups were also validated from artificially contaminated samples. Campylobacter strains were cultivated using an innovative gas generation system: The 'Portable Microbe Enrichment Unit' (PMEU) which provides microaerobic gas flow into the enrichment broth. This enhanced cultivation system produced rapid growth of several isolates of campylobacteria from water and chicken samples. The latter were obtained from local marketplace samples. No yersinias were found in the field studies, whereas they were readily recovered from the spiked samples, as well as Salmonella sp. and Escherichia coli strains. The PMEU method turned out to be reliable for monitoring of water and food hygiene in remote locations. PMID:25156815

    Background In sub-Saharan Africa, bovine tuberculosis (bTB) is a potential hazard for animals and humans health. The goal of this study was to improve our understanding of bTB epidemiology in Burkina Faso and especially Mycobacterium bovis transmission within and between the bovine and human populations. Methodology/principal findings Twenty six M. bovis strains were isolated from 101 cattle carcasses with suspected bTB lesions during routine meat inspections at the Bobo Dioulasso and Ouagadougou slaughterhouses. In addition, 7 M. bovis strains were isolated from 576 patients with pulmonary tuberculosis. Spoligotyping, RDAf1 deletion and MIRU-VNTR typing were used for strains genotyping. The isolation of M. bovis strains was confirmed by spoligotyping and 12 spoligotype signatures were detected. Together, the spoligotyping and MIRU-VNTR data allowed grouping the 33 M. bovis isolates in seven clusters including isolates exclusively from cattle (5) or humans (1) or from both (1). Moreover, these data (genetic analyses and phenetic tree) showed that the M. bovis isolates belonged to the African 1 (Af1) clonal complex (81.8%) and the putative African 5 (Af5) clonal complex (18.2%), in agreement with the results of RDAf1 deletion typing. Conclusions/Significance This is the first detailed molecular characterization of M. bovis strains from humans and cattle in Burkina Faso. The distribution of the two Af1 and putative Af5 clonal complexes is comparable to what has been reported in neighbouring countries. Furthermore, the strain genetic profiles suggest that M. bovis circulates across the borders and that the Burkina Faso strains originate from different countries, but have a country-specific evolution. The genetic characterization suggests that, currently, M. bovis transmission occurs mainly between cattle, occasionally between cattle and humans and potentially between humans. This study emphasizes the bTB risk in cattle but also in humans and the difficulty to set up

    Epidemiologic data related to agricultural pesticide poisoning cases in Burkina Faso were collected. The study was carried out using retrospective (from January 2002 to June 2010) surveys conducted among farmers and healthcare centers. One hundred and fifty-three (153) pest control products were recorded during the survey and 56 active ingredients were identified. Out of the 153 pest control products, 49 (i.e. 32%) were authorized for sale in Burkina Faso. The main risk factors are socio-demographic characteristics of farmers, their low education level, and some attitudes and practices on using agricultural pesticides. Pesticide poisonings are relatively frequent and their management was not always efficacious. Actions are needed to reduce pesticide poisoning as a global public health problem and to improve management of pesticide poisoning. To this purpose, advanced investigations should be carried out over a longer period of time to complement the present pilot study. PMID:24678256

    OBJECTIVE: To identify factors associated with decision to enrol in a community health insurance (CHI) scheme. METHODS: We conducted a population-based case-control study among 15 communities offered insurance in 2004 in rural Burkina Faso. For inclusion in the study, we selected all 154 enrolled (cases) and a random sample of 393 non-enrolled (controls) households. We used unconditional logistic regression (applying Huber-White correction to account for clustering at the community level) to explore the association between enrolment status and a set of household head, household and community characteristics. FINDINGS: Multivariate analysis revealed that enrolment in CHI was associated with Bwaba ethnicity, higher education, higher socioeconomic status, a negative perception of the adequacy of traditional care, a higher proportion of children living within the household, greater distance from the health facility, and a lower level of socioeconomic inequality within the community, but not with household health status or previous household health service utilization. CONCLUSION: Our study provides evidence that the decision to enrol in CHI is shaped by a combination of household head, household, and community factors. Policies aimed at enhancing enrolment ought to act at all three levels. On the basis of our findings, we discuss specific policy recommendations and highlight areas for further research.

    There are many small ferruginous outcrops of different facies, often breccia-like, in the Neoproterozoic sedimentary formations in northern Burkina. These outcrops are made up of goethite and quartz, and are often along with high grades of various elements. It could be a question of gossans. Their large distribution in this part of the Taoudéni Basin offers it prospects as a province geochemically rich in Cu, Pb, Zn, Mo, As, Cd, Co... This basin would be a geochemical bin for ancient formations, which would have been evacuated before the Neoproterozoic. The ironstones would be the mark of further concentrations.

    In the context of rapid urbanization across Sub-Saharan Africa there is a critical need for more robust decision-making between different ways of providing sanitation services in existing and new peri-urban areas. In several countries, authorities tried to find solutions by developing strategies to address sanitation problems in the form of Strategic Sanitation Plans. In Burkina, Strategic Sanitation Plans have been elaborated and implemented since the 1990s. Fada N'Gourma, a secondary city in Burkina, also adopted a Strategic Plan for wastewater and excreta management in 2006. In this study we use material flow analysis as a decision making tool to verify technology options of the Plan. A model was developed and data was collected in order to assess material and nitrogen flows. The status quo situation was compared to scenario based on the proposals made in the Sanitation Plan. Results show that the technology options which were recommended improved human health in the short term. However, the options led to groundwater pollution in the medium term. Compared to the current situation, matter and nitrogen flows would increase by 7% and 7.4% respectively in groundwater. It is thus concluded that the proposed options will not achieve the Plan's stated objectives of environmental protection.

    Background There is concern about an increasing infiltration of markets by substandard and fake medications against life-threatening diseases in developing countries. This is particularly worrying with regard to the increasing resistance development of Plasmodium falciparum against affordable anti-malarial medications, which has led to a change to more expensive drugs in most endemic countries. Methods A representative sample of modern anti-malarial medications from licensed (public and private pharmacies, community health workers) and illicit (market and street vendors, shops) sources has been collected in the Nouna Health District in north-western Burkina Faso in 2006. All drugs were tested for their quality with the standard procedures of the German Pharma Health Fund-Minilab. Detected low standard drugs were re-tested with European Pharmacopoeia 2.9.1 standards for disintegration and ultraviolet-visible spectroscopy at the laboratory of the Heidelberg University for confirmation. Results Overall, 86 anti-malarial drug samples were collected, of which 77 samples have been included in the final analysis. The sample consisted of 39/77 (50%) chloroquine, 10/77 (13%) pyrimethamine-sulphadoxine, 9/77 (12%) quinine, 6/77 (8%) amodiaquine, 9/77 (12%) artesunate, and 4/77 (5%) artemether-lumefantrine. 32/77 (42%) drug samples were found to be of poor quality, of which 28 samples failed the visual inspection, nine samples had substandard concentrations of the active ingredient, four samples showed poor disintegration, and one sample contained non of the stated active ingredient. The licensed and the illicit market contributed 5/47 (10.6%) and 27/30 (90.0%) samples of substandard drugs respectively. Conclusion These findings provide further evidence for the wide-spread existence of substandard anti-malarial medications in Africa and call for strengthening of the regulatory and quality control capacity of affected countries, particularly in view of the now wider available

    Background This paper explores women’s experience and perception of cesarean birth in Burkina Faso and its social and economic implications within the household. Methods Five focus groups comprising mothers or pregnant women were conducted among residents of Bogodogo Health District in Ouagadougou to assess the perceptions of cesarean section (CS) by women in the community. In addition, 35 individual semistructured interviews were held at the homes of women who had just undergone CS in the referral hospital, and were conducted by an anthropologist and a midwife. Results Home visits to women with CS identified common fears about the procedure, such as “once you have had a CS, you will always have to deliver by CS”. The central and recurring theme in the interviews was communication between patients and care providers, ie, women were often not informed of the imminence of CS in the delivery room. Information given by health care professionals was often either not explicit enough or not understood. The women received insufficient information about postoperative personal hygiene, diet, resumption of sexual activity, and contraception. Overall, analysis of the experiences of women who had undergone CS highlighted feelings of guilt in the aftermath of CS. Other concerns included the feeling of not being a “good mother” who can give birth normally, alongside concerns about needing a CS in future pregnancies, the high costs that this might incur for their households, general fatigue, and possible medical complications after surgery. Conclusion Poor quality of care and the economic burden of CS place women in a multifaceted situation of vulnerability within the family. CS has a medical, emotional, social, and economic impact on poor African women that cannot be ignored. Managers of maternal health programs need to understand women’s perceptions of CS so as to overcome existing barriers to this life-saving procedure. PMID:24851057

    Guinea fowls in Burkina Faso (Africa) harbored 13 species of helminth parasites. The two most abundant species were Subulura suctoria and Ascaridia numidae, which comprised 89% of the nematodes. The other nematode species (Gongylonema congolense, Eucoleus annulatus, Synhimantus spiralis, Tetrameres fissispina, and Cyrnea parroti) occurred at low levels. Five species of cestodes and one acanthocephalan were also present. It is likely that guinea fowl act as important reservoir hosts of chicken nematodes.

  3. Measuring women's perceived ability to overcome barriers to healthcare seeking in Burkina Faso

    2012-01-01

    Background In sub-Saharan Africa, women must overcome numerous barriers when they need modern healthcare. Respect of gender norms within the household and the community may still influence women's ability to obtain care. A lack of gender-sensitive instruments for measuring women's ability to overcome barriers compromises attempts to adequately quantify the burden and risk of exclusion they face when seeking modern healthcare. The aim of this study was to create and validate a synthetic measure of women's access to healthcare from a publicly available and possibly internationally comparable population-based survey. Method Seven questionnaire items from the Burkina Faso 2003 DHS were combined to create the index. Cronbach's alpha coefficient was used to test the reliability of the index. Exploratory factor analyses (EFA) and confirmatory factor analyses (CFA) were applied to evaluate the factorial structure and construct validity of the index while taking into account the hierarchical structure of the data. Results The index has a Cronbach's alpha of 0.75, suggesting adequate reliability. In EFA, three correlated factors fitted the data best. In CFA, the construct of perceived ability to overcome barriers to healthcare seeking emerged as a second-order latent variable with three domains: socioeconomic barriers, geographical barriers and psychosocial barriers. Model fit indices support the index's global validity for women of reproductive age in Burkina Faso. Evidence for construct validity comes from the finding that women's index scores increase with household living standard. Conclusion The DHS items can be combined into a reliable and valid, gender-sensitive index quantifying reproductive-age women's perceived ability to overcome barriers to healthcare seeking in Burkina Faso. The index complies conceptually with the sector-cross-cutting capability approach and enables measuring directly the perceived access to healthcare. Therefore it can help to improve the

    The views of a geographer, agricultural scientist, and women's activist focused on the importance of improving women's status and involvement in development. Women in Burkina Faso have shown an ability to organize themselves, but there was insufficient coordination among aid organizations. Researchers and development professionals must broaden and deepen their knowledge about climate, farming methods and traditional natural resource management methods, and women's concerns and occupations. Women need to be engaged in the planning and implementation of natural resource management strategies and in learning about appropriate training and information dissemination methods. The expertise in environmental disciplines is concentrated in developed nations and is needed by Sahelian women. Burkina's environment is replete with droughts, lack of forested areas, and dependence on subsistence farming. Famine and mass migration of men to urban areas have left women in poverty. Women must work 14-16 hours a day to provide food for their families and help husbands with cash crops. About 25% of women die from malnutrition, anemia, repeated pregnancies, malaria, and overexertion, as reported in a 1987 UNICEF study. The literature on women in Burkina Faso has focused only on broad issues of women's status. The few studies of local conditions conducted on a small scale by nongovernmental organizations have revealed that women were 60-80% of the labor force on anti-desertification projects. Women's overwhelming work load prevented even greater participation in environmental protection. Property laws gave land titles to men or the state. Women's groups have set up cereal banks, village pharmacies, and other self help projects pertaining to health, the environment, and agriculture. Women in development individual programs have not sufficiently integrated women and programs were archaic and dispersed. Environmental enforcement was limited.

    A comprehensive survey of the plant parasitic nematodes associated with cowpea (Vigna unguiculata) production fields was carried out in the three primary agro-climatic zones of Burkina Faso in West Africa. Across the three zones, a total of 109 samples were collected from the farms of 32 villages to provide a representative coverage of the cowpea production areas. Samples of rhizosphere soil and samples of roots from actively growing cowpea plants were collected during mid- to late-season. Twelve plant-parasitic nematode genera were identified, of which six appeared to have significant parasitic potential on cowpea based on their frequency and abundance. These included Helicotylenchus, Meloidogyne, Pratylenchus, Scutellonema, Telotylenchus, and Tylenchorhynchus. Criconemella and Rotylenchulus also had significant levels of abundance and frequency, respectively. Of the primary genera, Meloidogyne, Pratylenchus, and Scutellonema contained species which are known or suspected to cause losses of cowpea yield in other parts of the world. According to the prevalence and distribution of these genera in Burkina Faso, their potential for damage to cowpea increased from the dry Sahelian semi-desert zone in the north (annual rainfall < 600 mm/year), through the north-central Soudanian zone (annual rainfall of 600-800 mm/year), to the wet Soudanian zone (annual rainfall ≥ 1000 mm) in the more humid south-western region of the country. This distribution trend was particularly apparent for the endoparasitic nematode Meloidogyne and the migratory endoparasite Pratylenchus. PMID:22661784

    Birimian supracrustal sequences in NE Burkina Faso are dominated by meta-volcaniclastic greywacke, intercalated meta-conglomerate, siltstone and shale. The sequences where subjected to two phases of deformation and contact metamorphosed to hornblende-hornfels facies during emplacement of pyroxenite-gabbro-norite (Yacouba Mafic complex), granodiorite-tonalite (Tin Taradat granodiorite-tonalite) and dolerite dykes. Structural studies indicated that the NE-trending, first-order crustal-scale Markoye Shear Zone (MSZ; Markoye Fault of [Jeambrun, M., Delfour, J., Gravost, M., 1970. Carte géologique de L'Oudalan. Bureau De Recherches Geologiques et Miniéres, Burkina Faso.]) has undergone at least two phases of reactivation concomitant to two phases of regional deformation. The first phase of deformation, D1, resulted in the formation of NNW-NW trending folds and thrusts during dextral-reverse displacement on the MSZ. The deformation is termed the Tangaean Event and predates the Eburnean Orogeny. D2 phase involved a period of SE-NW crustal shortening and sinistral-reverse displacement on the MSZ, and is correlated to the Eburnean Orogeny ˜2.1 Ga. Deformation in D2 is characterised by NE-trending regional folds (F2) and a pervasive NE-trending foliation (S2-C to S2). Within the MSZ, deformation is characterised by NNE-trending zones of mylonite that are bordered in the hangingwall and footwall by pseudotachylite veins. Buck quartz-carbonate veins and quartz cataclasite veins crosscut the mylonite zones and are, in turn, crosscut by quartz-chlorite-(muscovite) shears that formed during reactivation of the MSZ late in D2. Several generations of veins are recognised at the Essakane main deposit (EMZ): Arsenopyrite-pyrite-gold mineralization in quartz veins formed in D1 during metasomatic alteration of the host rocks; Vein-stockwork gold mineralization is interpreted to have formed late in D2.

    People screened for human immunodeficiency virus (HIV) using rapid diagnostic tests (RDTs) in Africa remain generally unaware of their status for hepatitis B (HBV) and hepatitis C (HCV) infections. We evaluated a two-step screening strategy in Burkina Faso, using both HIV RDTs and Dried Blood Spot (DBS) assays to confirm an HIV-positive test, and to test for HBV and HCV infections. HIV counselling and point-of-care testing were performed at a voluntary counselling and testing centre with HBV, HCV status and HIV confirmation using DBS specimens, being assessed at a central laboratory. Serological testing on plasma was used as the reference standard assay to control for the performance of DBS assays. Nineteen out of 218 participants included in the study were positive for HIV using RDTs. A fourth-generation HIV ELISA and immunoblot assays on DBS confirmed HIV status. Twenty-four out of 25 participants infected with HBV were found positive for hepatitis B surface antigen (HBsAg) using DBS. One sample with a low HBsAg concentration on plasma was not detected on DBS. Five participants tested positive for HCV antibodies were confirmed positive with an immunoblot assay using DBS specimens. Laboratory results were communicated within 7 days to participants with no loss to follow up of participants between the first and second post-test counselling sessions. In conclusion, DBS collection during HIV point-of-care testing enables screening and confirmation of HBV, HCV and HIV infections. Diagnosis using DBS may assist with implementation of national programmes for HBV, HCV and HIV screening and clinical care in middle- to low-income countries. PMID:23902574

    This paper examines the concept of vulnerability in the context of maternal morbidity and mortality in Burkina Faso, an impoverished country in West Africa. Drawing on a longitudinal cohort study into the consequences of life-threatening or 'near miss' obstetric complications, we provide an in-depth case study of one woman's experience of such morbidity and its aftermath. We follow Kalizeta's trajectory from her near miss and the stillbirth of her child to her death from pregnancy-related hypertension after a subsequent delivery less than two years later, in order to examine the impact of severe and persistent illness and catastrophic health expenditure on her health and on her family's everyday life. Kalizeta's case illustrates how vulnerability in health emerges and is maintained or exacerbated over time. Even where social arrangements are supportive, structural impediments, including unaffordable and inadequate healthcare, can severely limit individual resilience to mitigate the negative social and economic consequences of ill health.

    This paper describes the status quo of the power sector in Burkina Faso, its limitations, and develops a new methodology that through spatial analysis processes with the aim to provide a possible pathway for universal electricity access. Following the SE4All initiative approach, it recommends the more extensive use of distributed renewable energy systems to increase access to electricity on an accelerated timeline. Less than 5% of the rural population in Burkina Faso have currently access to electricity and supply is lacking at many social structures such as schools and hospitals. Energy access achievements in Burkina Faso are still very modest. According to the latest SE4All Global Tracking Framework (2015), the access to electricity annual growth rate in Burkina Faso from 2010 to 2012 is 0%. The rural electrification strategy for Burkina Faso is scattered in several electricity sector development policies: there is a need of defining a concrete action plan. Planning and coordination between grid extension and the off-grid electrification programme is essential to reach a long-term sustainable energy model and prevent high avoidable infrastructure investments. This paper goes into details on the methodology and findings of the developed Geographic Information Systems tool. The aim of the dynamic planning tool is to provide support to the national government and development partners to define an alternative electrification plan. Burkina Faso proves to be paradigm case for the methodology as its national policy for electrification is still dominated by grid extension and the government subsidising fossil fuel electricity production. However, the results of our analysis suggest that the current grid extension is becoming inefficient and unsustainable in order to reach the national energy access targets. The results also suggest that Burkina Faso’s rural electrification strategy should be driven local renewable resources to power distributed mini-grids. We find that

    The northern distribution limit of tsetse flies was updated in Burkina Faso and compared to previous limits to revise the existing map of these vectors of African trypanosomiases dating from several decades ago. From 1949 to 2009, a 25- to 150-km shift has appeared toward the south. Tsetse are now discontinuously distributed in Burkina Faso with a western and an eastern tsetse belt. This range shift can be explained by a combination of decreased rainfall and increased human density. Within a context of international control, this study provides a better understanding of the factors influencing the distribution of tsetse flies. PMID:20617055

    Background Acute respiratory infections (ARIs) are a major cause of morbidity and mortality in children in Africa. The circulation of viruses classically implicated in ARIs is poorly known in Burkina Faso. The aim of this study was to identify the respiratory viruses present in children admitted to or consulting at the pediatric hospital in Ouagadougou. Methods From July 2010 to July 2011, we tested nasal aspirates of 209 children with upper or lower respiratory infection for main respiratory viruses (respiratory syncytial virus (RSV), metapneumovirus, adenovirus, parainfluenza viruses 1, 2 and 3, influenza A, B and C, rhinovirus/enterovirus), by immunofluorescence locally in Ouagadougou, and by PCR in France. Bacteria have also been investigated in 97 samples. Results 153 children (73.2%) carried at least one virus and 175 viruses were detected. Rhinoviruses/enteroviruses were most frequently detected (rhinovirus n = 88; enterovirus n = 38) and were found to circulate throughout the year. An epidemic of RSV infections (n = 25) was identified in September/October, followed by an epidemic of influenza virus (n = 13), mostly H1N1pdm09. This epidemic occurred during the period of the year in which nighttime temperatures and humidity were at their lowest. Other viruses tested were detected only sporadically. Twenty-two viral co-infections were observed. Bacteria were detected in 29/97 samples with 22 viral/bacterial co-infections. Conclusions This study, the first of its type in Burkina Faso, warrants further investigation to confirm the seasonality of RSV infection and to improve local diagnosis of influenza. The long-term objective is to optimize therapeutic management of infected children. PMID:25360527

    Pernicious anemia (also known as Biermer disease or anemia, Addison or Addisonian anemia, and Addison-Biermer anemia) is an autoimmune atrophic gastritis responsible for vitamin B12 malabsorption due to a deficiency of intrinsic factor. We report eight cases of pernicious anemia in Burkina Faso, collected over a 44-month period. The three criteria for diagnosis of pernicious anemia were: vitamin B12 deficiency, gastric disease (gastric histology) with presence of anti-intrinsic factor, and/or anti-gastric parietal cell antibodies in serum. All patients had anemia, with a mean hemoglobin level of 8.75 g/100 mL. The average mean corpuscular volume (MCV) was 122.1 fL the average mean corpuscular hemoglobin (MCH) 39.3 pg, the mean reticulocyte count 12.069 10(9)/L reticulocytes, and the mean rate of megaloblast marrow cells 17.2%. The serum vitamin B12 level ranged from 35 to 71 pmol/L. Antibodies against intrinsic factor were found in all eight patients. All ABO blood groups were present with a predominance (4 cases) of group O. Endoscopy found a normal fundic mucosa in three patients. Histology showed gastric atrophy and intestinal metaplasia for six patients (85.7%). Under B12 vitamin therapy, the course was favorable in all patients; seven patients also had 10 days of iron therapy. We recommend a gastric biopsy even in the absence of macroscopic gastric lesions on the upper gastrointestinal endoscopy. PMID:25787024

    OBJECTIVE: To assess the impact of the National Immunization Days (NIDs) on measles vaccine coverage in Burkina Faso in 1998. METHODS: During the week after the campaign, in which measles vaccine was offered to children aged 9-59 months in six cities regardless of vaccination history, a cluster survey was conducted in Ouagadougou and Bobo Dioulasso, the country's two largest cities. Interviewers visited the parents of 1267 children aged up to 59 months and examined vaccination cards. We analysed the data using cluster sample methodology for the 1041 children who were aged 9-59 months. FINDINGS: A total of 604 (57%) children had received routine measles vaccination prior to the campaign, and 823 (79%) were vaccinated during the NIDs. Among those who had previously had a routine vaccination, 484 (81%) were revaccinated during the NIDs. Among those not previously vaccinated, 339 (78%) received one dose during the NIDs. After the campaign, 943 (91%) children had received at least one dose of measles vaccine. Better socioeconomic status was associated with a higher chance of having been vaccinated routinely, but it was not associated with NID coverage. CONCLUSION: The mass campaign enabled a substantial increase in measles vaccine coverage to be made because it reached a high proportion of children who were difficult to reach through routine methods.

    The Society of Gynaecologists and Obstetricians of Burkina Faso (SOGOB) conducted a project to reinforce skills in respectful maternity care among its members and health workers at three facilities. The participatory process allowed health workers to self-diagnose quality of care, recognize their own responsibility, propose solutions, and pledge respectful care commitments that were specific for each unit. Key commitments included good reception; humanistic clinical examination; attentive listening and responsiveness to patient needs; privacy, discretion, and confidentiality; availability; and comfort. These commitments can potentially be modified after each evaluation by SOGOB. Poor working conditions were found to negatively impact on quality of care. High staff turnover, frequent technical malfunctions, and inadequate infrastructure were identified as issues that require future focus to ensure improvements in quality of care are sustainable. Programs that aim to improve the maternity experience by linking good practice with humanistic care merit rollout to all healthcare facilities in Burkina Faso.

    Background Micro health insurance schemes have been implemented across developing countries as a means of facilitating access to modern medical care, with the ultimate aim of improving health. This effect, however, has not been explored sufficiently. Objective We investigated the effect of enrolment into community-based health insurance on mortality in children under 5 years of age in a health and demographic surveillance system in Nouna, Burkina Faso. Design We analysed the effect of health insurance enrolment on child mortality with a Cox regression model. We adjusted for variables that we found to be related to the enrolment in health insurance in a preceding analysis. Results Based on the analysis of 33,500 children, the risk of mortality was 46% lower in children enrolled in health insurance as compared to the non-enrolled children (HR=0.54, 95% CI 0.43–0.68) after adjustment for possible confounders. We identified socioeconomic status, father's education, distance to the health facility, year of birth, and insurance status of the mother at time of birth as the major determinants of health insurance enrolment. Conclusions The strong effect of health insurance enrolment on child mortality may be explained by increased utilisation of health services by enrolled children; however, other non-observed factors cannot be excluded. Because malaria is a main cause of death in the study area, early consultation of health services in case of infection could prevent many deaths. Concerning the magnitude of the effect, implementation of health insurance could be a major driving factor of reduction in child mortality in the developing world. PMID:25925193

    Management of the hydrologic cycle is critical to the primary livelihood of a large part of semi-arid West Africa's primary livelihood, rain-fed farming. We use flux measurements from an eddy-covariance station coupled with a dense network of small wireless meteorological stations to examine the relationship between land surface properties (albedo, soil moisture, and roughness) and evapotranspiration in a small (3.5 km2) catchment in Burkina Faso, West Africa. The catchment is a matrix of savanna and agricultural land maintained under various regimes, providing a comparison of multiple land use types of Sudanian Wooded Savanna including a canyon gallery forest, agroforestry parklands, occasionally grazed semi-open savanna, a semi-closed wooded slope, fallow fields, rice paddies, and ephemeral wetlands. By filtering out times when dry air was entrained, we demonstrate the small control of soil moisture and vegetation on the evaporative fraction, which was not initially visible. Additionally we document the high contribution of the gallery forest to the the catchment evaporation, despite its small size. These small meteorological stations could be paired with currently available satellite data to calculate evaporation over a much larger area, even when eddy-covariance equipment is not available. These findings reinforce local cultural beliefs of the importance of gallery forests for climate regulation and may provide tools to key local decision makers, rural farmers.

    A significant correlation exists between the concentration of parasites, bacteria and some water quality parameters including surface suspended solids (SSS) and turbidity. Suspended particles can carry viruses and pathogenic bacteria affecting human health and foster their development. High SSS, associated with high turbidity, can therefore be considered as a vector of microbiological contaminants, causing diarrheal diseases. Few studies have focused on the turbidity parameter in rural Africa, while many cases of intestinal parasitic infections are due to the consumption of unsafe water from ponds, lakes, and rivers. Monitoring turbidity may therefore contribute to health hazard monitoring. Turbidity refers to the optical properties of water and is known to impact water reflectance in the visible and near-infrared domain. Ideally, its spatial and temporal variability requires the use of high temporal resolution (MODIS) and spatial resolution (Landsat, SPOT, Sentinel-2). Here we investigate turbidity in West-Africa. Various algorithms and indices proposed in the literature for inland waters are applied to MODIS series and to Landsat 7 and 8 CDR images, and SPOT5 images. The data and algorithms are evaluated with field measurements: turbidity, SSS, and hyperspectral ground radiometry. We show that turbidity of the Bagre Lake displays a strong increase over 2000-2015, associated with the corresponding increase of the red and NIR reflectances, as well as a reduction of the seasonal variations. Water level derived from the Jason 2 altimeter does not explain such variations. The most probable hypothesis is a change in land use (increase in bare and degraded soils), that leads to an increase in the particles transported by surface runoff to the lake. Such an increase in turbidity reinforces the health risk. We will discuss the link between turbidity and health in view of data from health centers on diarrheal diseases as well as data on practices and uses of populations.

    Yellow vein disease (YVD) is a major problem in pepper in West Africa. Despite the recent implication of a begomovirus in YVD in Mali and in Burkina Faso, the aetiology of the disease remains unclear. Using symptomatic samples from the main vegetable cultivation regions in Burkina Faso, 10 full-length DNA-A-like begomovirus sequences were obtained, each showing 98% nucleotide identity to pepper yellow vein Mali virus (PepYVMV). The host range was determined after construction of a viral clone for agroinfection. Severe symptoms developed in tomato and Nicotiana benthamiana. By contrast, no symptoms developed in either commercial or local pepper cultivars, demonstrating that the aetiology of YVD is not only associated with the presence of PepYVMV.

    Although, HIV-2 is generally less pathogenic than HIV-1 and its progression towards AIDS occurs less frequently. HIV-2 remains an important cause of disease in West Africa. This study aimed to evaluate HIV-1 and HIV-2 prevalence among pregnant women and to describe the demographic and clinical profile of patients with HIV-2 infection from 2003-2013 at St Camille and General Lamizana Military Medical Centers. A retrospective investigation was conducted using 12,287 medical records from patients screened for HIV. To respond to the lack of data available regarding HIV-2 treatment and also to address the approach to clinical, biological as well as therapeutic monitoring, 62 HIV-2 infected patients' medical records were studied. Seroprevalence of 10.6 and 0.14% were obtained, respectively for HIV-1 and HIV-2 among 12,287 women screened during the study period. From the sixty two (62) HIV-2 patients, the average age was 49.2 years (sex ratio was 0.65). The weight loss and diarrhea were the major clinical manifestations observed, respectively 54.8 and 25.8%. Fungi and herpes zoster (shingles) infections were reported as major opportunistic infections. Also, nearly half of the patients had more than 60 kg, less than 2% were in WHO stage IV and about 2/3 had a CD4 count bellow 250 cells mm(-3). AZT-3TC-IDV/LPV/R was the most prescribed combination. The gain in weight gain the Body Mass Index (BMI) improvement and the non-significant increase of the rate of CD4 between 1st (M1) and 24th month (M24) were observed after treatment with antiviral.

  5. Perinatal mortality in rural Burkina Faso: a prospective community-based cohort study

    Background There is a scarcity of reliable data on perinatal mortality (PNM) in Sub-Saharan Africa. The PROMISE-EBF trial, during which we promoted exclusive breastfeeding, gave us the opportunity to describe the epidemiology of PNM in Banfora Health District, South-West in Burkina Faso. Study objectives To measure the perinatal mortality rate (PNMR) in the PROMISE-EBF cohort in Banfora Health District and to identify potential risk factors for perinatal death. Methods We used data collected prospectively during the PROMISE-EBF-trial to estimate the stillbirth rate (SBR) and early neonatal mortality rate (ENMR). We used binomial regression with generalized estimating equations to identify potential risk factors for perinatal death. Results 895 pregnant women were enrolled for data collection in the EBF trial and followed-up to 7 days after birth. The PNMR, the SBR and the ENMR, were 79 per 1000 (95% CI: 59-99), 54 per 1000 (95% CI: 38-69) and 27 per 1000 (95% CI: 9-44), respectively. In a multivariable analysis, nulliparous women (RR = 2.90, 95% CI: 1.6-5.0), primiparae mothers (RR = 2.20, 95% CI: 1.2-3.9), twins (RR = 4.0, 95% CI: 2.3-6.9) and giving birth during the dry season (RR = 2.1 95% CI: 1.3-3.3) were factors associated with increased risk of perinatal death. There was no evidence that risk of perinatal death differed between deliveries at home and at a health centre Conclusion Our study observed the highest PNMR ever reported in Burkina. There is an urgent need for sustainable interventions to improve maternal and newborn health in the country. PMID:20716352

    Diets of hartebeest (Alcelaphus buselaphus) and roan antelope (Hippotragus equinus) were assessed at the Nazinga Game Ranch in southern Burkina Faso, West Africa. Microhistological analysis of feces indicated that dietary overlap was high during the rainy (X?? = 73.7%) and cool-dry (68.2%) seasons, low during the hot-dry season (48.2%), and lowest during the last month of the hot-dry season (31.5%). As the hot-dry season progressed and food presumably became less available, diets of the two antelopes diverged. Hartebeest maintained a high percentage of grass in their diet, but roan antelope switched from being predominantly grazers (>95% grass) to mixed feeders (<50% grass). As grass feeders, both antelopes have skeletal features that facilitate acquisition and grinding of highly fibrous diets, but 11 of 12 mass-relative indices of the skull morphology of hartebeest exceeded those of roan antelope. Because of those differences in skull morphology, and in keeping with the "long-faced" hypothesis, hartebeest were apparently more capable than roan antelope of acquiring and masticating scarce regrowth of perennial grasses when availability of forage was lowest. Such divergence within a single foraging class of African bovids, such as grass feeders, should reduce competition and perpetuate coexistence.

    This article explores the discrepancies between the vocal public discourse on HIV/AIDS and sexuality as generally encouraged by policy-makers and donor communities in Africa, and the often hushed voices of their target groups: young people in African communities. Based on fieldwork among urban youth in Senegal and Burkina Faso, we describe the silence of young people with regard to HIV/AIDS and sexuality as a social phenomenon, with focus given to family relations, peer relations and gender aspects in partnerships. Drawing on Foucault and Morrell, an inability and unwillingness to speak about HIV/AIDS and sexuality are analysed as a response to an everyday life characterised by uncertainty. This response represents a certain degree of resistance, while it constitutes a major barrier to any HIV/AIDS prevention effort. Finally, we stress that despite great constraints in their everyday lives, young people have some room to manoeuvre and are able to apply some negotiating strategies to reduce sexually-related health risks.

    Effective mechanisms to exempt the indigent from user fees at health care facilities are rare in Africa. A State-led intervention (2004-2005) and two action research projects (2007-2010) were implemented in a health district in Burkina Faso to exempt the indigent from user fees. This article presents the results of the process evaluation of these three interventions. Individual and group interviews were organized with the key stakeholders (health staff, community members) to document the strengths and weaknesses of key components of the interventions (relevance and uptake of the intervention, worst-off selection and information, financial arrangements). Data was subjected to content analysis and thematic analysis. The results show that all three intervention processes can be improved. Community-based targeting was better accepted by the stakeholders than was the State-led intervention. The strengths of the community-based approach were in clearly defining the selection criteria, informing the waiver beneficiaries, using a participative process and using endogenous funding. A weakness was that using endogenous funding led to restrictive selection by the community. The community-based approach appears to be the most effective, but it needs to be improved and retested to generate more knowledge before scaling up.

    Dental amalgam is a metallic restorative material that is used for direct filling of carious lesions since many years. The use of this material generates solid and particulate wastes that present potential challenges to the environment. This study was carried out to assess amalgam use and waste management protocols practiced by Moroccan and Burkinabe dentists. A cross-sectional study was made of 79 in Rabat, Sale and Temara in Morocco and 56 in Ouagadougou, Bobo-Dioulasso in Burkina-Faso. The results showed that 69.5% of dental amalgam waste in Morocco vs 49.9% in Burkina-Faso was disposed with household waste which is a problem for both the environment and a risk to human being. Proper methods of dental amalgam waste disposal should be carried out to prevent indirect mercury poisoning for human.

For the same period, 22 women out of 455 students (4.8%) were enrolled in PhD (all the fields of the Exact and Applied Sciences Unit) and three women out of 180 students (1.7%) registered in physics PhD. During the 3rd IUPAP International Conference on Women in Physics in 2008, the Burkina Faso Working Group proposed some strategies to attract more women to physics and all the sciences. Some actions were initiated at the University of Ouagadougou as well as in secondary schools. These actions and the feedback of female students are presented.

    The relationship between religious obligations and female genital cutting is explored using data from Burkina Faso, a religiously and ethnically diverse country where approximately three-quarters of adult women are circumcised. Data from the 2003 Burkina Faso Demographic and Health Survey are used to estimate multilevel models of religious variation in the intergenerational transmission of female genital cutting. Differences between Christians, Muslims, and adherents of traditional religions are reported along with an assessment of the extent to which individual and community characteristics account for religious differences. Religious variation in the intergenerational transmission of female genital cutting is largely explained by specific religious beliefs and by contextual rather than individual characteristics. Although Muslim women are more likely to have their daughter circumcised, the findings suggest the importance of a collective rather than individual Muslim identity for the continuation of the practice.

    In Burkina Faso, although children are sometimes separated from adults in prisons, they still live in the same conditions of overcrowding, which can reach 180% of the capacity. The aim of our study was to describe living conditions, nutritional status, and morbidity of children in detention centers of Burkina Faso. The objective of this cross-sectional descriptive study is to describe the social and health conditions of children held in 20 detention centers in Burkina Faso. During the study period, 109 children, with a mean age of 16.3 years, were examined in 20 correction centers. The main reason for incarceration was theft (66% cases, n = 72). Detention exceeded more than one month for 76 children (70%), and 59% (N = 46) had had fewer than one visit per month since their incarceration. Of these 20 facilities, 6 had no separate quarters for children. The main symptoms and diseases encountered in these children were fever in 19% of the cases (N = 16), macroscopic hematuria in 13% (N = 11), urinary tract infection in 12% (N = 10) and diarrhea in 12% (N = 10). These results show that there is a need to take preventive measures to protect these children's health, especially by improving the quality of living conditions in detention center. PMID:26038843

    Background Effective and timely treatment is an essential aspect of malaria control, but remains a challenge in many parts of sub-Saharan Africa. The objective of this study was to describe young children's access to malaria treatment in Nouna Health District, Burkina Faso. Methods In February/March 2006, a survey was conducted in a representative sample of 1,052 households. Results Overall 149/1052 (14%) households reported the current possession of anti-malarial medicine, which was significantly associated with urban area, literacy of household head, having young children, and high socio-economic status. Out of a total of 802 children under five years, at least one malaria episode was reported for 239 (30%) within the last month. Overall 95% of children received treatment, either modern (72%), traditional (18%) or mixed (5%). Most of the medicines were provided as home treatment by the caregiver and half of children received some type of modern treatment within 24 hours of the occurrence of first symptoms. Despite a recent policy change to artemisinin-based combination therapy, modern anti-malarials consisted mainly of chloroquine (93%). Modern drugs were obtained more often from a health facility in localities with a health facility compared to those without (60% vs. 25.6%, p < 0.001). In contrast, beside informal providers, volunteer community health workers (CHW) were the main source of modern medicine in localities without a health centre (28% vs. 3%, p < 0.001). Conclusion Access to modern health services providing quality controlled effective combination therapies against malaria needs to be strengthened in rural Africa, which should include a re-investigation of the role of CHW 30 years after Alma Ata.

    In the first half of the XXth century, while Upper-Volta (now Burkina Faso) was suffering a terrible epidemic of sleeping sickness, the French colonial administration encouraged the movement of people from Upper-Volta to Ivory Coast to meet their demands for labour. This led to the establishment of Mossi villages, such as those of Koudougou, in the Ivorian forest with populations originating from areas of Upper-Volta that were not only densely populated but also severely affected by sleeping sickness. Since 2000, most cases of sleeping sickness in the Koudougou district of Burkina Faso have been in people originally from Ivory Coast. Who are they? Where did they settle in Burkina Faso? Where do they come from in Ivory Coast? After having retraced the epidemiological history of Koudougou villages in Burkina Faso and Ivory Coast, the history of ten cases of sleeping sickness detected passively at Koudougou hospital since 2000 were analysed. All cases originated from the forest area of Ivory Coast. Understanding the spread of sleeping sickness between Burkina Faso and Ivory Coast will assist in the identification of areas of disease risk.

    The Sahel—the belt of land that stretches across Africa on the southern edge of the Sahara—has always been a tough place to farm. Rainfall is low and droughts are frequent. The crust of hard soil is, at times, almost impermeable, and harsh winds threaten to sweep away everything in their path. Over the past three decades, however, hundreds of thousands of farmers in Burkina Faso and Niger have transformed large swaths of the region’s arid landscape into productive agricultural land, improving food security for about 3 million people. Once-denuded landscapes are now home to abundant trees, crops, and livestock. Although rainfall has improved slightly from the mid-1990s relative to earlier decades, indications are that farmer management is a stronger determinant of land and agroforestry regeneration. Sahelian farmers achieved their success by ingeniously modifying traditional agroforestry, water, and soil-management practices. To improve water availability and soil fertility in Burkina Faso’s Central Plateau, farmers have sown crops in planting pits and built stone contour bunds, which are stones piled up in long narrow rows that follow the contours of the land in order to capture rainwater runoff and soil. These practices have helped rehabilitate between 200,000 and 300,000 hectares of land and produce an additional 80,000 tons of food per year. In southern Niger, farmers have developed innovative ways of regenerating and multiplying valuable trees whose roots already lay underneath their land, thus improving about 5 million hectares of land and producing more than 500,000 additional tons of food per year. While the specific calculations of farm-level benefits are subject to various methodological and data limitations, the order of magnitude of these benefits is high, as evidenced by the wide-scale adoption of the improved practices by large numbers of farmers. Today, the agricultural landscapes of southern Niger have considerably more tree cover than they

    Abstract Objective To assess the impact of a decade of biennial mass administration of praziquantel on schistosomiasis in school-age children in Burkina Faso. Methods In 2013, in a national assessment based on 22 sentinel sites, 3514 school children aged 7–11 years were checked for Schistosoma haematobium and Schistosoma mansoni infection by the examination of urine and stool samples, respectively. We analysed the observed prevalence and intensity of infections and compared these with the relevant results of earlier surveys in Burkina Faso. Findings S. haematobium was detected in 287/3514 school children (adjusted prevalence: 8.76%, range across sentinel sites: 0.0–56.3%; median: 2.5%). The prevalence of S. haematobium infection was higher in the children from the Centre-Est, Est and Sahel regions than in those from Burkina Faso’s other eight regions with sentinel sites (P < 0.001). The adjusted arithmetic mean intensity of S. haematobium infection, among all children, was 6.0 eggs per 10 ml urine. Less than 1% of the children in six regions had heavy S. haematobium infections – i.e. at least 50 eggs per 10 ml urine – but such infections were detected in 8.75% (28/320) and 11.56% (37/320) of the children from the Centre-Est and Sahel regions, respectively. Schistosoma mansoni was only detected in two regions and 43 children – i.e. 1 (0.31%) of the 320 from Centre-Sud and 42 (8.75%) of the 480 from Hauts Bassins. Conclusion By mass use of preventive chemotherapy, Burkina Faso may have eliminated schistosomiasis as a public health problem in eight regions and controlled schistosome-related morbidity in another three regions.

    Background. In Sub-Saharan Africa, maternal and neonatal morbidity and mortality rates are associated with underutilization of skilled birth attendance (SBA). In 2007, Burkina Faso introduced a subsidy scheme for SBA fees. The objective of this study was to evaluate the effect of Burkina Faso’s subsidy policy on SBA rate across socioeconomic status (SES) strata. Methods. We used a quasi-experimental design. The data sources were two representative surveys (n = 1408 and n = 1403) of women from Houndé and Ziniaré health districts of Burkina Faso, and a survey of health centres assessing structural quality of care. Multilevel Poisson regression models were used with robust variance estimators. We estimated adjusted rate ratios (RR) and rate differences (RD) as a function of time and SES. Results. For lowest-SES women, immediately upon the introduction of the subsidy policy, the rate of SBA was 45% higher (RR = 1.45, 95% confidence interval (CI): 1.19–1.77) than expected in the absence of subsidy introduction. The results indicated a sustained effect after introduction of the subsidy policy, based on RR estimate (95% CI) of 1.48 (1.21–1.81) at 2 years. For middle-SES women, the RR estimates were 1.28 (1.09–1.49) immediately after introduction of the subsidy policy and 1.30 (1.11–1.51) at 2 years, respectively. For highest-SES women, the RR estimates were 1.19 (1.02–1.38) immediately after subsidy introduction and 1.21 (1.06–1.38) at 2 years, respectively. The RD (95% CI) was 14% (3–24%) for lowest-SES women immediately after introduction of the policy, and the effect was sustained at 14% (4–25%) at 2 years. Conclusion. Our study suggests that the introduction of a user-fee subsidy in Burkina Faso resulted in increased rates of SBA across all SES strata. The increase was sustained over time and strongest among the poorest women. These findings have important implications for evidence-informed policymaking in Burkina Faso and other

    Background Clinical trials conducted in Africa often require substantial investments to support trial centres and public health facilities. Trial resources could potentially generate benefits for routine health service delivery but may have unintended consequences. Strengthening ethical practice requires understanding the potential effects of trial inputs on the perceptions and practices of routine health care providers. This study explores the influence of malaria vaccine trials on health service delivery in Ghana, Kenya and Burkina Faso. Methods We conducted: audits of trial inputs in 10 trial facilities and among 144 health workers; individual interviews with frontline providers (n=99) and health managers (n=14); and group discussions with fieldworkers (n=9 discussions). Descriptive summaries were generated from audit data. Qualitative data were analysed using a framework approach. Results Facilities involved in trials benefited from infrastructure and equipment upgrades, support with essential drugs, access to trial vehicles, and placement of additional qualified trial staff. Qualified trial staff in facilities were often seen as role models by their colleagues; assisting with supportive supervision and reducing facility workload. Some facility staff in place before the trial also received formal training and salary top-ups from the trials. However, differential access to support caused dissatisfaction, and some interviewees expressed concerns about what would happen at the end of the trial once financial and supervisory support was removed. Conclusion Clinical trials function as short-term complex health service delivery interventions in the facilities in which they are based. They have the potential to both benefit facilities, staff and communities through providing the supportive environment required for improvements in routine care, but they can also generate dissatisfaction, relationship challenges and demoralisation among staff.

    In recent years the sale of pharmaceutical products by unlicensed vendors outside the official public health system has grown in Africa in general and in Burkina Faso in particular. The purpose of the present study was to identify the persons involved and their motivations, sources of supply, chains of distribution, and strengths and weaknesses of the parallel market. Data were collected using a two-part questionnaire. The first part focused on a certain category of buyer, i.e., mothers with children under the age of 5 years and the second part focused on medicine vendors working outside the official system. Accidental sample allowed contact with 41 vendors and cluster sampling obtained 340 mothers whose children presented fever within the last 30 days. Illicit sale of medicine appears to involve mainly young males with little or no formal education. The sex ratio was 0.25 including 34.1% with schooling and 65.9% with no schooling. The main motives of the vendors were money (18/41) and unemployment (12/41). The remaining 11 vendors stated that they wanted to help people who did not have access to a nearby health center. The business appears to be lucrative since the average daily income was estimated at 2.815 F CFA (ranges: 255 F CFA to 10.000 F CFA). Customers stated several reasons for buying on the illicit market but the most frequent reason was affordability. According to 98% of mothers drugs were cheaper on the illicit market than on the official market. Most mothers declared that their resources were insufficient to purchase higher-priced licit pharmaceutical products. Other factors accounted for buying drugs on the parallel market. Although it is considered as illicit, the market has the advantage of being socially adapted and responsive to consumer habits, expectations and needs.

    Insecticidal activity of eight plants collected from Burkina Faso was studied using mosquito (Ochlerotatus triseriatus), Helicoverpa zea and Heliothis virescens larvae and adult white fly (Bemisia tabaci). The n-hexane, ethyl acetate and methanol extracts of Pseudocedrela kotschyi, Strophantus hispidus, Securidaca longepedunculata, Sapium grahamii, Swartzia madagascariensis, Cassia nigricans, Jatropha curcas and Datura innoxia were used in this study. Extracts were tested at 250 microg/mL concentration. All three extracts of C. nigricans, J. curcas (skin and seeds) and D. innoxia exhibited 100% mortality on fourth instar mosquito (O. triseriatus) larvae. In addition, the n-hexane and ethyl acetate extracts of S. hispidus, S. longepedunculata, S. grahamii showed 100% mortality. The ethyl acetate extract of S. madagascariensis was the most active on adult white fly and exhibited 80% mortality. Extracts of all other plants exhibited 30-50% mortality on B. tabaci. In the antifeedant assays against H. zea and H. virescens, the MeOH extracts of C. nigricans, S. madagascarensis and S. hispidus were more effective against H. zea as indicated by 74% larval weight reduction as compared to the control. Since C. nigricans is commonly used in West Africa to protect grain storage from insects, we have characterized the insecticidal components present in its extract. Bioassay directed isolation of C. nigricans leaf extract yielded anthraquinones emodin, citreorosein, and emodic acid and a flavonoid, luteolin. Emodin, the most abundant and active anthraquinone in C. nigricans showed approximately 85% mortality on mosquito larvae Anopheles gambiaea and adult B. tabaci at 50 and 25 microg/mL, respectively, in 24 h. These results suggest that the extract of C. nigricans has the potential to be used as an organic approach to manage some of the agricultural pests. PMID:17478091

    OBJECTIVE: To determine why patients attend dental-care facilities in Ouagadougou, Burkina Faso and to improve understanding of the capacity of oral health-care services in urban west Africa. METHODS: We studied a randomly selected sample of patients attending 15 dental-care facilities in Ouagadougou over a 1-year period in 2004. Data were collected using a simple daily record form. FINDINGS: From a total of 44,975 patients, the final sample was established at 14,591 patients, of whom 55.4% were new patients and 44.6% were "booking patients". Most patients seeking care (71.9%) were aged 15-44 years. Nongovernmental not-for-profit dental services were used by 41.5% of all patients, 36% attended private dental-care services, and 22.5% of patients visited public services. The most common complaint causing the patient to seek dental-care services was caries with pulpal involvement (52.4%), and 60% of all complaints were associated with pain. The patients' dental-care requirements were found to differ significantly according to sex, health insurance coverage and occupation. CONCLUSION: Urban district health authorities should ensure provision of primary health-care services, at the patients' first point of contact, which are directed towards the relief of pain. In addition to the strengthening of outreach emergency care, health centres should also contribute to the implementation of community-based programmes for the prevention of oral disease and the promotion of oral health. Exchange of experiences from alternative oral health-care systems relevant to developing countries is urgently needed for tackling the growing burden of oral disease. PMID:16211155

    Land surface characteristics are the main control on hydrologic processes, the driver of most livelihoods, in semi arid West Africa. We use the energy and water balance measured with two eddy-covariance towers, coupled with a dense network of small, wireless meteorological stations in a small (3.5 km2) catchment to understand these relationships. Time series of monthly averages of soil moisture, rainfall, air temperature, cloud cover, components of net radiation, wind speed, and NDVI are presented in relation to the evaporative fraction and energy balance. We found that both latent and sensible heat fluxes are greater over mixed forest and savanna areas compared agricultural land. Sensible heat is found to be most different between the two land-covers at the end of the year, when the grass and vegetation is dry, and latent heat is found to be most different at the beginning of the year, when bare ground dominates. Further examination shows that soil moisture and vegetation indexes provide the main controls on evaporative fraction. These findings have implications for modeling the evaporation over large regions based on remotely sensed land surface temperature. The site is characteristic of the contrasts in vegetation and moisture availability present in the rocky escarpments found in Northern Benin and Southeastern Burkina Faso. Historically these sites are important in location for village choice and land use designation. These findings reinforce local cultural beliefs of the importance of vegetation for climate regulation and may provide support to local farmers for improving the resilience of natural resources and livelihood security.

  8. Adapting to an innovation: Solar cooking in the urban households of Ouagadougou (Burkina Faso)

    NASA Astrophysics Data System (ADS)

    Toonen, Hilde M.

    Most households in Sub-Saharan Africa rely on wood as primary energy source. The availability of wood is decreasing and deforestation is a major ecological problem in Sub-Saharan Africa. The scarcity of wood is demanding for a sustainable solution. The sun seems to provide a good alternative. Solar energy is free, without unhealthy smoke or chances to burns. The idea of using solar energy for cooking is not new: many different techniques have already been tested. Most variants are expensive, and therefore not available for most families in Sub-Saharan Africa. A cheap solar cooking device is the CooKit, a cardboard panel cooker covered with aluminium foil. In the adaptation to the CooKit, as to all innovations, it is important that the users are convinced of the advantages. An important step in the adaptation process is learning how to use the cooking device; the best way to do this is by home practice. Monitoring and evaluating the real use is needed, for it is interesting to know if the CooKit is actually used, and also to find out how women have implemented the new technique in their kitchens. In 2005, the SUPO foundation started a project in Burkina Faso: Programme Energie Solaire Grand-Ouaga (PESGO). The aim of PESGO is to introduce the CooKit in the urban households in Ouagadougou by providing training sessions and home assistance. In this paper, a mid-term review on this small-scale cooking project is presented. The possibilities and challenges of solar cooking are outlined, taking the urban context of Ouagadougou in account. In PESGO, dependence on weather conditions is found to be one of the challenges: if sunrays are blocked by clouds or dust in the air, the cooking will be slowed down. The CooKit cannot replace firewood entirely, and a complementary element has to be found. SUPO is exploring the use of Jatropha oil as a complement to the CooKit. The Jatropha plant is drought tolerant and its fruits contain oil which can be used as fuel substitute. Further

    2011-01-01

    Background Human papillomaviruses are the most common sexually transmitted infections, and genital warts, caused by HPV-6 and 11, entail considerable morbidity and cost. The natural history of genital warts in relation to HIV-1 infection has not been described in African women. We examined risk factors for genital warts in a cohort of high-risk women in Burkina Faso, in order to further describe their epidemiology. Methods A prospective study of 765 high-risk women who were followed at 4-monthly intervals for 27 months in Burkina Faso. Logistic and Cox regression were used to identify factors associated with prevalent, incident and persistent genital warts, including HIV-1 serostatus, CD4+ count, and concurrent sexually transmitted infections. In a subset of 306 women, cervical HPV DNA was tested at enrolment. Results Genital wart prevalence at baseline was 1.6% (8/492) among HIV-uninfected and 7.0% (19/273) among HIV-1 seropositive women. Forty women (5.2%) experienced at least one incident GW episode. Incidence was 1.1 per 100 person-years among HIV-uninfected women, 7.4 per 100 person-years among HIV-1 seropositive women with a nadir CD4+ count >200 cells/μL and 14.6 per 100 person-years among HIV-1 seropositive women with a nadir CD4+ count ≤200 cells/μL. Incident genital warts were also associated with concurrent bacterial vaginosis, and genital ulceration. Antiretroviral therapy was not protective against incident or persistent genital warts. Detection of HPV-6 DNA and abnormal cervical cytology were strongly associated with incident genital warts. Conclusions Genital warts occur much more frequently among HIV-1 infected women in Africa, particularly among those with low CD4+ counts. Antiretroviral therapy did not reduce the incidence or persistence of genital warts in this population. PMID:21251265

    Background The aim of this paper was to evaluate the effectiveness and cost-effectiveness of alternative training strategies for increasing access to emergency obstetric care in Burkina Faso. Methods Case extraction forms were used to record data on 2305 caesarean sections performed in 2004 and 2005 in hospitals in six out of the 13 health regions of Burkina Faso. Main effectiveness outcomes were mothers' and newborns' case fatality rates. The costs of performing caesarean sections were estimated from a health system perspective and Incremental Cost-Effectiveness Ratios were computed using the newborn case fatality rates. Results Overall, case mixes per provider were comparable. Newborn case fatality rates (per thousand) varied significantly among obstetricians, general practitioners and clinical officers, at 99, 125 and 198, respectively. The estimated average cost per averted newborn death (x 1000 live births) for an obstetrician-led team compared to a general practitioner-led team was 11 757 international dollars, and for a general practitioner-led team compared to a clinical officer-led team it was 200 international dollars. Training of general practitioners appears therefore to be both effective and cost-effective in the short run. Clinical officers are associated with a high newborn case fatality rate. Conclusion Training substitutes is a viable option to increase access to life-saving operations in district hospitals. The high newborn case fatality rate among clinical officers could be addressed by a refresher course and closer supervision. These findings may assist in addressing supply shortages of skilled health personnel in sub-Saharan Africa. PMID:19371433

    Background Communicable diseases are the leading causes of illness, deaths, and disability in sub-Saharan Africa. To address these threats, countries within the World Health Organization (WHO) African region adopted a regional strategy called Integrated Disease Surveillance and Response (IDSR). This strategy calls for streamlining resources, tools, and approaches to better detect and respond to the region's priority communicable disease. The purpose of this study was to analyze the incremental costs of establishing and subsequently operating activities for detection and response to the priority diseases under the IDSR. Methods We collected cost data for IDSR activities at central, regional, district, and primary health care center levels from Burkina Faso, Eritrea, and Mali, countries where IDSR is being fully implemented. These cost data included personnel, transportation items, office consumable goods, media campaigns, laboratory and response materials and supplies, and annual depreciation of buildings, equipment, and vehicles. Results Over the period studied (2002–2005), the average cost to implement the IDSR program in Eritrea was $0.16 per capita, $0.04 in Burkina Faso and $0.02 in Mali. In each country, the mean annual cost of IDSR was dependent on the health structure level, ranging from $35,899 to $69,920 at the region level, $10,790 to $13,941 at the district level, and $1,181 to $1,240 at the primary health care center level. The proportions spent on each IDSR activity varied due to demand for special items (e.g., equipment, supplies, drugs and vaccines), service availability, distance, and the epidemiological profile of the country. Conclusion This study demonstrates that the IDSR strategy can be considered a low cost public health system although the benefits have yet to be quantified. These data can also be used in future studies of the cost-effectiveness of IDSR. PMID:19133149

    This research addresses the dual challenge faced by Burkina Faso engineers to design sustainable low-energy cost public buildings and domestic dwellings while still providing the required thermal comfort under warmer temperature conditions caused by climate change. It was found base don climate change SRES scenario A2 that predicted mean temperature in Burkina Faso will increase by 2oC between 2010 and 2050. Therefore, in order to maintain a thermally comfortable 25oC inside public buildings, the projected annual energy consumption for cooling load will increase by 15%, 36% and 100% respectively for the period between 2020 to 2039, 2040 to 2059 and 2070 to 2089 when compared to the control case. It has also been found that a 1% increase in population growth will result in a 1.38% and 2.03% increase in carbon emission from primary energy consumption and future electricity consumption respectively. Furthermore, this research has investigated possible solutions for adaptation to the severe climate change and population growth impact on energy demand in Burkina Faso. Shading devices could potentially reduce the cooling load by up to 40%. Computer simulation programming of building energy consumption and a field study has shown that adobe houses have the potential of significantly reducing energy demand for cooling and offer a formidable method for climate change adaptation. Based on the Net Present Cost, hybrid photovoltaic (PV) and Diesel generator energy production configuration is the most cost effective local electricity supply system, for areas without electricity at present, with a payback time of 8 years when compared to diesel generator stand-alone configuration. It is therefore a viable solution to increase electricity access to the majority of the population.

    Hepatitis A virus (HAV) and hepatitis E virus (HEV) infections occur chiefly as a result of unhygienic conditions. The purpose of this study was to assess the seroprevalence of antibodies to both viruses in central Burkina Faso in the absence of a recorded hepatitis epidemic. Serum samples from 178 blood donors (131 males and 47 females) and from 189 pregnant women were collected from November 2010 to March 2012, at blood banks and medical centers in Burkina Faso. An immunochromatography test was used to screen for Anti-HAV IgM and IgG in a subgroup of 91 blood donors and 100 pregnant women. The seroprevalence of anti-HAV IgG was 14.3% [CI95, 7.1–21.4%] for all blood donors and 23% [CI95, 14.8–31.2%] for pregnant women. Anti-HEV IgG were detected using the ELISA kits Dia.pro and Wantai and were found in 19.1% [CI95, 13.3–24.9%] of the blood donors and 11.6% [CI95, 7.1–16.2%] of the pregnant women. The seroprevalences of anti-HAV and anti-HEV IgGs did not differ significantly between men and women blood donors. Anti-HAV IgM was detected in 3.3% of the blood donors and in 2% of the pregnant women. These findings for asymptomatic individuals indicate that the HAV and HEV circulate at low but significant levels. This is the first evaluation of the acute hepatitis virus burden in Burkina Faso and the underlying epidemiologic status of the population. PMID:23110187

    Volcanic facies and preliminary geochemical observations of the Goren greenstone belt, Burkina Faso L.F.H. Peters and K.A.A Hein School of Geosciences, University of the Witwatersrand, Private Bag 3, Wits 2050, South Africa. The Goren Greenstone Belt (GGB) is a Palaeoproterozoic volcano-sedimentary belt situated in the northeast of Burkina Faso in the West African craton (WAC). Basalt is the main volcanic constituent of the GGB, specifically mid-ocean ridge basalts (MORBS), which have undergone pervasive greenschist facies metamorphism during at least 2 deformation including the Tangaean Event (2170-2130 Ma) and Eburnean Orogeny (2130-1980 Ma). Remarkably, many of the primary textures and minerals remain intact in less deformed regions of the GBB. Textural characteristics and petrographic analyses include aphyric and aphanitic textures, amygdales, hyaloclastic brecciation, pillow structures and preserved (chloritised) volcanic glass. Despite the ubiquitous presence of chlorite and epidote, plagioclase and clinopyroxene microlites are fairly common albeit altered. Phenocrysts (< 1 mm) of plagioclase and CPX are present in some samples but aphyric texture is dominant. These textures indicate that the basalts represent coherent units of sub-aqueous extrusion from a proximal volcanic facies setting relative to the original magma conduit. A repetitious succession of Fe-rich meta-siltstones, fine-grained, carbonaceous, Fe-rich exhalatives and volcaniclastic units is intercalated with the basalts. The volcaniclastic units contrast with the MORBs, which raises questions about the source region of the volcaniclastics. In hand sample, the volcaniclastic rocks show an array of various sized fragments, compared to the fine-grained nature of the MORBs. They are dominated by euhedral, zoned, brown volcanic hornblende, large (2.5-5 mm) euhedral plagioclase crystals, and sub-angular to rounded quartz grains in a poorly sorted volcanogenic sedimentary sequence.

    Population policies are currently at the center of debates about demography and development, and are a preoccupation of most governments, international organizations, and research institutions working in the areas of population, development, and human resources. Between 1988-93, 4 Sahel countries adopted populations policies. this article compares the policies of Senegal, Mali, and Burkina Faso. The 3 policy documents have similar structures, with preambles recalling the international agreements concerning population and development entered into by their governments. A chapter on population and development describes the demo-economic problem in each country at regional, sectorial, and global levels. After the analysis of demo-economic problems, each of the 3 has a chapter presenting the population policy. Each presentation covers the foundations and basic principles of the policy, its objectives, the strategies to be pursued, and the organizational structure. Development of each policy was technically supervised by the Planning Ministry in collaboration with the national population councils. In general terms, the 3 countries recognize in their basic principles that the population is the primary source of wealth of a nation. Each country states its desire to translate the recommendations of different African and world population conferences into concrete acts. The principles avow respect for fundamental human rights including the right to informed decision making by couples on number and spacing of children. The principles also recognize the need for an integrated approach to population and development. The ultimate objective of the population policies is improvement in the standard and quality of life. The number of general objectives outlined in the policies varied from 7 in Senegal to 13 in Burkina Faso. Senegal was the only country of the 3 to specify reduction of the fertility rate and the growth rate as an objective. Senegal and Burkina Faso included

    Objectives Research about the mental health of children in Francophone West Africa is scarce. This paper examines the relationships between adverse childhood experiences, including exposure to violence and exploitation, and mental health outcomes among children living in ultra-poverty in rural Burkina Faso. Methods This paper utilizes baseline data collected from 360 children ages 10–15 and 360 of their mothers recruited from twelve impoverished villages in the Nord Region of Burkina, located near the Sahel Desert and affected by extreme food insecurity. We used a Latent Class Analysis to identify underlying patterns of maltreatment. Further, the relationships between latent classes and mental health outcomes were tested using mixed effected regression models adjusted for clustering within villages. Results About 15% of the children in the study scored above the clinical cut-off for depression, 17.8% for posttraumatic stress disorder (PTSD), and 6.4% for low self-esteem. The study identified five distinct sub-groups (or classes) of children based on their exposure to adverse childhood experiences. Children with the highest exposure to violence at home, at work and in the community (Abused and Exploited class) and children not attending school and working for other households, often away from their families (External Laborer class), demonstrated highest symptoms of depression and trauma. Despite living in adverse conditions and working to assist families, the study also identified a class of children who were not exposed to any violence at home or at work (Healthy and Non-abused class). Children in this class demonstrated significantly higher self-esteem (b = 0.92, SE = 0.45, p<0.05) and lower symptoms of trauma (b = -3.90, SE = 1.52, p<0.05). Conclusions This study offers insight into the psychological well-being of children in the context of ultra-poverty in Burkina Faso and associated context-specific adverse childhood experiences.

    As a step towards universal health coverage, African countries need to develop funding systems that are effective, equitable, and tailored to national circumstances. To support policy makers in Burkina Faso, we present a review of research on interventions related to user fees, prepayment plans, and user fee subsidies. We compiled a narrative summary of articles published in scientific journals between 1980 and 2012. In all, 64 articles were selected. A thematic analysis was performed. User fees are a barrier to access to care; they curtail the use of health services and exclude the worst-off. People prefer prepayment plans in which each household pays an annual premium. However, the insurance premium remains a barrier to membership. Insurance does not benefit the poor but increases the use of health services by the insured. The subsidy for facility-based deliveries was not sufficiently well planned and difficulties have been observed in its implementation. While it helps reduce costs and improves access to care, it has not reduced inequalities. Community-based and participatory interventions have been useful for identifying the worst-off in order to exempt them from user fees. While prepayment is being promoted internationally as a financing model for universal health coverage, the evidence in favour of this system in Burkina Faso is still very limited. Further studies, more representative of the national context, must be conducted on this option, while at the same time, continuing efforts must be made to identify solutions for the poor who are unable to pay.

    The bottled drinking water marketed in urban areas includes natural mineral water, spring water, and treated drinking water. Their physicochemical qualities depend on the type and quantity of their components and define their safe use. Bottled water is widely consumed in Ouagadougou (Burkina Faso), and many brand names exist. Although many publications have examined the microbiological qualities of such water, no study has examined the physicochemical quality of water from Burkina Faso. This study, conducted from March 2005 through January 2006, aimed to assess the physicochemical composition of drinking water sold in Ouagadougou to facilitate better choices and use by consumers. Results showed that all the water analyzed in Ouagadougou is soft (TH < 50 ppm) or moderately soft (50 < TH < 200 ppm) and weakly mineralized (total dissolved solid content < 500 mg/L, sulfates [SO(2-)(4)] < 200 mg/L, [Ca(++)] < 150 mg/L, [Mg(2+)] < 50 mg/L, and [HCO(3)-] < 600 mg/l). Some imported water, however, is hard and highly mineralized. French standards do not set limit values for the natural mineral water parameters described above, and much of the water sold in Ouagadougou was natural mineral water. The spring water met potability standards, except for the Montagne d'Arrée brand, which had a pH value of 5.8, below the WHO standards of 6.5 < pH 8.5.

    Unsafe abortion constitutes a major public health problem in Burkina Faso and concerns mainly young women. The legal restriction and social stigma make abortions most often clandestine and risky for women who decide to terminate a pregnancy. However, the exposure to the risk of unsafe induced abortion is not the same for all the women who faced unwanted pregnancy and decide to have an abortion. Drawn from a qualitative study on the issue of abortion in Ouagadougou, Burkina Faso's capital, the contrasting cases of two young women who had abortion allow us to show how the women's personal resources (such as the school level, financial resources, the compliance to social norms, the social network, etc.) may determine the degree of vulnerability of women, the delay to have an abortion, the type of care they are likely to benefit from, and the cost they have to face. This study concludes that the poorest always pay more (cost and consequences), take longer to have an abortion, and have more exposure to the risk of unsafe abortion. PMID:24790605

    This article presents a linguistic analysis of data from an ongoing research project exploring HIV/AIDS education in West African Burkina Faso. I argue that we can identify different, sometimes even competing, discourses about the disease in prevention interactions. Thus, communication about HIV/AIDS in Burkina Faso--and probably in most of the Sub-Saharan countries--might be characterized by what I will call, with reference to Bakhtin, discursive heteroglossia. There is clear evidence of such discursive heteroglossia, that is, the participants' alignment to local and global HIV discourses, deployed in the communication of health workers. In my analysis of peer educators training sessions, I draw on theoretical and methodological principles from discourse analysis and interactional linguistics. I focus on the linguistic devices and conversational strategies the participants use to indicate the relevance of the local or the global discourses. Three particular devices--namely, metaphors, epistemic and evidential markers, and word explanations--will be examined in a more detailed way. I will also show how the local and the global interweave at different levels of prevention discourse.

    Unsafe abortion constitutes a major public health problem in Burkina Faso and concerns mainly young women. The legal restriction and social stigma make abortions most often clandestine and risky for women who decide to terminate a pregnancy. However, the exposure to the risk of unsafe induced abortion is not the same for all the women who faced unwanted pregnancy and decide to have an abortion. Drawn from a qualitative study on the issue of abortion in Ouagadougou, Burkina Faso's capital, the contrasting cases of two young women who had abortion allow us to show how the women's personal resources (such as the school level, financial resources, the compliance to social norms, the social network, etc.) may determine the degree of vulnerability of women, the delay to have an abortion, the type of care they are likely to benefit from, and the cost they have to face.

    As a step towards universal health coverage, African countries need to develop funding systems that are effective, equitable, and tailored to national circumstances. To support policy makers in Burkina Faso, we present a review of research on interventions related to user fees, prepayment plans, and user fee subsidies. We compiled a narrative summary of articles published in scientific journals between 1980 and 2012. In all, 64 articles were selected. A thematic analysis was performed. User fees are a barrier to access to care; they curtail the use of health services and exclude the worst-off. People prefer prepayment plans in which each household pays an annual premium. However, the insurance premium remains a barrier to membership. Insurance does not benefit the poor but increases the use of health services by the insured. The subsidy for facility-based deliveries was not sufficiently well planned and difficulties have been observed in its implementation. While it helps reduce costs and improves access to care, it has not reduced inequalities. Community-based and participatory interventions have been useful for identifying the worst-off in order to exempt them from user fees. While prepayment is being promoted internationally as a financing model for universal health coverage, the evidence in favour of this system in Burkina Faso is still very limited. Further studies, more representative of the national context, must be conducted on this option, while at the same time, continuing efforts must be made to identify solutions for the poor who are unable to pay.

    The aim of this study was to assess potential changes in dietary habits during pregnancy in a rural community in Houndé district, Burkina Faso. In-depth interviews were performed on a random sample of 37 pregnant women in order to analyse specific perceptions and attitudes regarding food consumption during pregnancy. In addition to this, an interactive 24-h recall survey was used to compare the food intake of 218 pregnant and 176 non-pregnant women. The majority of interviewees reported dietary restrictions during pregnancy but no consistent pattern of avoided food types was found. Most of the mentioned 'forbidden' foods were in related to physical discomfort during gestation. Interviewees also admitted to ignoring culturally determined food prohibitions/prescriptions. No differences were observed in food intake, food choice and nutrient intake between the group of pregnant and non-pregnant women. During the third trimester of gestation women did not show any major differences in food and nutrient intake compared with women from the first/second trimester. The mean nutrient intakes were found to be insufficient compared with the recommended daily allowances, especially for pregnant women. In conclusion, pregnant women in this rural area of Burkina Faso do not seem to restrict their diet significantly during pregnancy. The additional nutritional requirements of pregnancy are not accounted for in their dietary practises.

    In theory, the removal of user fees puts health services within reach of everyone, including the very poor. When Burkina Faso adopted the DOTS strategy for the control of tuberculosis, the intention was to provide free tuberculosis care. In 2007-2008, interviews were used to collect information from 242 smear-positive patients with pulmonary tuberculosis who were enrolled in the national tuberculosis control programme in six rural districts. The median direct costs associated with tuberculosis were estimated at 101 United States dollars (US$) per patient. These costs represented 23% of the mean annual income of a patient's household. During the course of their care, three quarters of the interviewed patients apparently faced "catastrophic" health expenditure. Inadequacies in the health system and policies appeared to be responsible for nearly half of the direct costs (US$ 45 per patient). Although the households of patients developed coping strategies, these had far-reaching, adverse effects on the quality of lives of the households' members and the socioeconomic stability of the households. Each tuberculosis patient lost a median of 45 days of work as a result of the illness. For a population living on or below the poverty line, every failure in health-care delivery increases the risk of "catastrophic" health expenditure, exacerbates socioeconomic inequalities, and reduces the probability of adequate treatment and cure. In Burkina Faso, a policy of "free" care for tuberculosis patients has not met with complete success. These observations should help define post-2015 global strategies for tuberculosis care, prevention and control.

    Labor migration from Burkina Faso did not end when direct recruitment of workers by planters from the Ivory Coast was terminated at independence in 1960. Methodological problems and differences in the objectives of the 1975 and 1985 censuses and the 1960-61 sample survey have limited the usefulness of existing data on migration. Migrants from Burkina Faso have always been unskilled workers in search of wage employment. The migrant population in 1960-61 was estimated at 152,442, of whom 90% were males primarily under 40 years old. The proportion of women and children increased from 8.2% in 1961 to 12.8% in 1973. Between the 1975 and 1985 censuses, there were few significant changes in the dominant characteristics of migrants. 80% of the 808,000 residents living abroad according to official sources were male and 80% were aged 15-40 years. 53% of migrants according to a 1975 study were under 20 years old at the 1st departure, and most were single. At the national level, labor migration is viewed as a necessary evil that should continue as long as possible in the absence of employment opportunities at home. After independence in 1960, 56.6% of migrants from Burkina Faso went to the Ivory Coast, 31.3% to Ghana, and 3.9% to Mali. In 1975 and 1985 respectively, 74.4% and 91.2% went to the Ivory Coast and 11.8% and 8.8% to Ghana. The demographic consequences of migration in Burkina Faso include a lowering of the natural increase rate and a reduction of the economically active population amounting to about 16% between 1975-85. The disproportionate departure of men has left an increasing number of women in charge of agricultural operations. A strong current of return migration has also developed, including many children under 15. It was estimated in 1990 that half of migrants to the Ivory Coast receive professional training, with the other half exposed to new agricultural techniques and methods of organizing work. 87% of returning male migrants in 1985 went back to their

    Okra leaf curl disease (OLCD) is a major constraint on okra (Abelmoschus esculentus) production and is widespread in Africa. Using a large number of samples representative of the major growing regions in Burkina Faso (BF), we show that the disease is associated with a monopartite begomovirus and satellite DNA complexes. Twenty-three complete genomic sequences of Cotton leaf curl Gezira virus (CLCuGV) isolates associated with OLCD, sharing 95 to 99% nucleotide identity, were cloned and sequenced. Six betasatellite and four alphasatellite (DNA-1) molecules were also characterized. The six isolates of betasatellite associated with CLCuGV isolates correspond to Cotton leaf curl Gezira betasatellite (CLCuGB) (88 to 98% nucleotide identity). One isolate of alphasatellite is a variant of Cotton leaf curl Gezira alphasatellite (CLCuGA) (89% nucleotide identity), whereas the three others isolates appear to correspond to a new species of alphasatellite (CLCuGA most similar sequence present 52 to 60% nucleotide identity), provisionally named Okra leaf curl Burkina Faso alphasatellite (OLCBFA). Recombination analysis of the viruses demonstrated the interspecies recombinant origin of all CLCuGV isolates, with parents being close to Hollyhock leaf crumple virus (AY036009) and Tomato leaf curl Diana virus (AM701765). Combined with the presence of satellites DNA, these results highlight the complexity of begomoviruses associated with OLCD.

    Data on mineral elements in spirulinas being limited, we analyzed macrominerals and trace elements of samples from France and Africa. Spirulinas cultivated in France have a composition in macromineral elements similar to those of the literature. The entire contents of trace elements are low. Unlike marine cyanobacteria, they do not concentrate rare-earth elements. Spirulina harvested in Chad has high levels in macrominerals and trace elements, due to traditional drying and harvesting methods. Rare-earth element levels are attributed to this pollution and not to their concentration in spirulinas, because rare-earth element normalized profiles of spirulina are strictly parallel to those of ouadis mud and very different from those of ouadis water. Despite the sometimes high content of total As, normal water consumption in Chad presents no health problems. Spirulinas grown in Togo, Niger, Mali, Burkina-Faso and Central African Republic have chemical compositions similar to those of Chad spirulinas, but with a lower content of macromineral and trace elements, reflecting a lower mineral pollution. Rare-earth element normalized patterns dismiss an aeolian pollution and the pollution is rather of pedological origin. They show no toxicity problem except spirulinas from Burkina-Faso, whose Pb content is too high. The variability of composition of spirulinas can be largely attributed to the mineral pollution of the samples. Significant levels of rare-earth elements sometimes found in the literature reflect this pollution.

    Background. Five years since the successful introduction of MenAfriVac in a mass vaccination campaign targeting 1- to 29-year-olds in Burkina Faso, consideration must be given to the optimal strategies for sustaining population protection. This study aims to estimate the economic impact of a range of vaccination strategies in Burkina Faso. Methods. We performed a cost-of-illness study, comparing different vaccination scenarios in terms of costs to both households and health systems over a 26-year time horizon. These scenarios are (1) reactive vaccination campaign (baseline comparator); (2) preventive vaccination campaign; (3) routine immunization at 9 months; and (4) a combination of routine and an initial catchup campaign of children under 5. Costs were estimated from a literature review, which included unpublished programmatic documents and peer-reviewed publications. The future disease burden for each vaccination strategy was predicted using a dynamic transmission model of group A Neisseria meningitidis. Results. From 2010 to 2014, the total costs associated with the preventive campaign targeting 1- to 29-year-olds with MenAfriVac were similar to the estimated costs of the reactive vaccination strategy (approximately 10 million US dollars [USD]). Between 2015 and 2035, routine immunization with or without a catch-up campaign of 1- to 4-year-olds is cost saving compared with the reactive strategy, both with and without discounting costs and cases. Most of the savings are accrued from lower costs of case management and household costs resulting from a lower burden of disease. After the initial investment in the preventive strategy, 1 USD invested in the routine strategy saves an additional 1.3 USD compared to the reactive strategy. Conclusions. Prevention strategies using MenAfriVac will be significantly cost saving in Burkina Faso, both for the health system and for households, compared with the reactive strategy. This will protect households from

    Introduction In Sub-Saharan Africa, few studies reported pregnancy incidence and outcomes in women taking antiretroviral therapy (ART). This survey aims to estimate the incidence and outcomes of pregnancy in a cohort of HIV positive women initiating ART in Bobo-Dioulasso, Burkina Faso. Methods We carried out a retrospective cohort study. We selected women in childbearing age initiating ART and followed up in Bobo-Dioulasso teaching hospital between January 2005 and June 2011. The incidence of pregnancies during follow-up was calculated. Childbirth was defined by the expulsion of a fetus after 22 weeks of amenorrhea. Before this term, it is an abortion. Childbirth is said premature if it occurs before 37 weeks of gestation, to term if it occurs between the 38th and the 42nd week. The annual age-standardized fertility rates were calculated using the baseline population from the 2010 demographic and health survey (DHS) in Burkina Faso. Results A total of 1,763 women of childbearing age under ART were included in the study. They ranged between 18 and 48 years old with a median of 35 years old. A total of 222 pregnancies were observed during 4639 women-years of follow-up, corresponding to an incidence density of 5 pregnancies for 100 women-years (95% CI: 4.2-5.5). Among the 222 pregnancies recorded, 9(4.0%) ended with abortion, 205(92.4%) with childbirth (including 15 premature childbirths); the outcome of 8(3.6%) pregnancies were unknown abortion. Live birth and stillborn rates were 94.0% (193/205) and 6.0% respectively. The standard fertility rate in our cohort was 45 live births for 1,000 women-years. The general decrease in fertility rates was 66.0% among women infected with HIV compared to the overall population Conclusion This study shows a low pregnancy incidence among women initiating ART as compared to their peers from the general population. Pregnancies that occurred during ART generally end with live births. Care packages for HIV infected women of

    Background Tsetse flies are the cyclical vectors of African trypanosomosis that constitute a major constraint to development in Africa. Their control is an important component of the integrated management of these diseases, and among the techniques available, the sterile insect technique (SIT) is the sole that is efficient at low densities. The government of Burkina Faso has embarked on a tsetse eradication programme in the framework of the PATTEC, where SIT is an important component. The project plans to use flies from a Glossina palpalis gambiensis colony that has been maintained for about 40 years at the Centre International de Recherche-Développement sur l'Elevage en zone Subhumide (CIRDES). It was thus necessary to test the competitiveness of the sterile males originating from this colony. Methodology/Principal Findings During the period January–February 2010, 16,000 sterile male G. p. gambiensis were released along a tributary of the Mouhoun river. The study revealed that with a mean sterile to wild male ratio of 1.16 (s.d. 0.38), the abortion rate of the wild female flies was significantly higher than before (p = 0.026) and after (p = 0.019) the release period. The estimated competitiveness of the sterile males (Fried index) was 0.07 (s.d. 0.02), indicating that a sterile to wild male ratio of 14.4 would be necessary to obtain nearly complete induced sterility in the female population. The aggregation patterns of sterile and wild male flies were similar. The survival rate of the released sterile male flies was similar to that observed in 1983–1985 for the same colony. Conclusions/Significance We conclude that gamma sterilised male G. p. gambiensis derived from the CIRDES colony have a competitiveness that is comparable to their competitiveness obtained 35 years ago and can still be used for an area-wide integrated pest management campaign with a sterile insect component in Burkina Faso.

    Introduction Although interventions to control HIV among high-risk groups such as female sex workers (FSW) are highly recommended in Africa, the contents and efficacy of these interventions are unclear. We therefore designed a comprehensive dedicated intervention targeting young FSW and assessed its impact on HIV incidence in Burkina Faso. Methods Between September 2009 and September 2011 we conducted a prospective, interventional cohort study of FSW aged 18 to 25 years in Ouagadougou, with quarterly follow-up for a maximum of 21 months. The intervention combined prevention and care within the same setting, consisting of peer-led education sessions, psychological support, sexually transmitted infections and HIV care, general routine health care and reproductive health services. At each visit, behavioural characteristics were collected and HIV, HSV-2 and pregnancy were tested. We compared the cohort HIV incidence with a modelled expected incidence in the study population in the absence of intervention, using data collected at the same time from FSW clients. Results The 321 HIV-uninfected FSW enrolled in the cohort completed 409 person-years of follow-up. No participant seroconverted for HIV during the study (0/409 person-years), whereas the expected modelled number of HIV infections were 5.05/409 person-years (95% CI, 5.01–5.08) or 1.23 infections per 100 person-years (p=0.005). This null incidence was related to a reduction in the number of regular partners and regular clients, and by an increase in consistent condom use with casual clients (adjusted odds ratio (aOR)=2.19; 95% CI, 1.16–4.14, p=0.01) and with regular clients (aOR=2.18; 95% CI, 1.26–3.76, p=0.005). Conclusions Combining peer-based prevention and care within the same setting markedly reduced the HIV incidence among young FSW in Burkina Faso, through reduced risky behaviours. PMID:26374604

    This qualitative assessment, based on discussions and discourse collected in interviews with members of the general population, addresses the popular view of pharmaceutical drugs in Burkina Faso. The main results demonstrate a strong preference for drugs sold in the street and their largely "off-label" uses. These drugs not only treat defined diseases but also generate street discussions, popular images and social relationships that lead to their consumption, sometimes excessive. Furthermore, the links between the legal and illegal street markets, related in part to the legal status of different drugs, also leads to questions about good and bad, true and false. These distinctions, considered as labels, influence the population's behavior and attitude concerning street medication.

    A country-scale (1:1,000,000) methodology has been developed for hydrogeologic mapping of hard-rock aquifers (granitic and metamorphic rocks) of the type that underlie a large part of the African continent. The method is based on quantifying the "useful thickness" and hydrodynamic properties of such aquifers and uses a recent conceptual model developed for this hydrogeologic context. This model links hydrodynamic parameters (transmissivity, storativity) to lithology and the geometry of the various layers constituting a weathering profile. The country-scale hydrogeological mapping was implemented in Burkina Faso, where a recent 1:1,000,000-scale digital geological map and a database of some 16,000 water wells were used to evaluate the methodology.

    Providing microcredit to women in developing countries has long been highlighted as a simple and effective strategy for poverty reduction and health improvement. However, little is known about how microcredit enables changes in health behaviour. This knowledge is critical to further strengthen microcredit initiatives. This qualitative study, conducted in Burkina Faso, shows how microcredit can not only facilitate savings and investment strategies, but also lead to changes in household decision-making, enabling women to initiate health prevention, seek health treatment and manage health emergencies. Some changes led to increased household burdens for women that impeded health gains, such as administrative loan delays by the microcredit institution and reduced household contributions by the husband. Furthermore, the study highlighted the fragile nature of health gains, which may be eroded due to economic shocks on a household, such as crop failure, drought or illness.

    Amniotic band syndrome is a rare congenital disorder. The authors report the first cases documented at Souro Sanou University Hospital in Bobo-Dioulasso (CHUSS) in 2 male new borns. The malformations found at birth, were worn only on limbs and were in the form of skin furrow necking with a major lymphedema downstream. In both cases, the constriction furrow at member pelvic was associated with a club foot and a pseudosyndactyly in one case. Surgical treatment consisted of a section of the constrictor ring and a Z-plasty. The functional outcome was satisfactory with the acquisition of a plantar support for both children. Through these two observations, epidemiological, diagnostic, and particularities of the management of this condition are discussed in the Burkina-Faso. PMID:26918082

    This study reports on the geochemical and mineralogical characterization of a lateritic profile cropping out in the Balkouin area, Central Burkina Faso, aimed at obtaining a better understanding of the processes responsible for the formation of the laterite itself and the constraints to its development. The lateritic profile rests on a Paleoproterozoic basement mostly composed of granodioritic rocks related to the Eburnean magmatic cycle passing upwards to saprolite and consists of four main composite horizons (bottom to top): kaolinite and clay-rich horizons, mottled laterite and iron-rich duricrust. In order to achieve such a goal, a multi-disciplinary analytical approach was adopted, which includes inductively coupled plasma (ICP) atomic emission and mass spectrometries (ICP-AES and ICP-MS respectively), X-ray powder diffraction (XRPD), scanning electron microscopy with energy dispersive spectrometry (SEM-EDS) and micro-Raman spectroscopy.

    Background. Malaria's prevalence during pregnancy varies widely in parts of sub-Saharan Africa, including Burkina Faso. The objective of this study was to evaluate the incidence of mother-to-child malaria transmission during childbirth at St. Camille Medical Centre in the city of Ouagadougou. Methods. Two hundred and thirty-eight (238) women and their newborns were included in the study. Women consenting to participate in this study responded to a questionnaire that identified their demographic characteristics. Asymptomatic malaria infection was assessed by rapid detection test Acon (Acon Malaria Pf, San Diego, USA) and by microscopic examination of Giemsa-stained thick and thin smears from peripheral, placental, and umbilical cord blood. Birth weights were recorded and the biological analyses of mothers and newborns' blood were also performed. Results. The utilization of long-lasting insecticidal nets (LLINs) and intermittent preventive treatment with sulfadoxine-pyrimethamine (SP) were 86.6% and 84.4%, respectively. The parasitic infection rates of 9.5%, 8.9%, and 2.8% were recorded, respectively, for the peripheral, placental, and umbilical cord blood. Placental infection was strongly associated with the presence of parasites in the maternal peripheral blood and a parasite density of >1000 parasites/µL. Conclusion. The prevalence of congenital malaria was reduced but was associated with a high rate of mother-to-child malaria transmission. PMID:25506464

    Global advocacy campaigns increasingly highlight the negative impact of reproductive morbidity on economic productivity and development in order to justify donor investment in maternal health. Anthropological approaches nuance such narrow economic estimations of reproductive health. Drawing on ethnographic fieldwork from Burkina Faso in West Africa, this paper analyses the dynamic, and sometimes contradictory, relationship between women's work and reproductive health in impoverished communities. Specifically, it examines the consequences of life-threatening 'near-miss' obstetric complications for women's work across domestic, agricultural and economic spheres over a four-year period. Such events provide a window onto the diverse ways in which production and reproduction are intimately linked within women's everyday lives. Reproduction and production entail sources of potential empowerment and enhancement, as well as potential threats, to health and well-being. In the aftermath of 'near-miss' events, the realms of reproduction and production sometimes jeopardise each other and at other times reinforce each other, while strength in one domain can compensate for weakness in the other. Women's experiences thus reveal how 'production' and 'reproduction' are mutually constituted, challenging the purely instrumental accounts of pregnancy-related 'productivity loss' that dominate current global health discourse.

    The Fada N'Gourma area in Burkina Faso is underlain by Paleoproterozoic rocks that make the northeastern West-African Craton. This region is composed of NE-trending volcano-sedimentary belts and foliated tonalites, affected by several shear zones. A generation of younger, ˜2100 Ma-old, non-foliated biotite-bearing granites intrudes the former rock units. We have investigated the younger granite pluton of Kouare that was previously considered as forming a single body with the pluton of Satenga to the west, a pluton which likely belongs to the ˜20 Ma more recent Tenkodogo-Yamba batholith. Magnetic fabric measurements have been combined with microstructural observations and the analysis of field and aeromagnetic data. The granite encloses angular enclaves of the host tonalites. Magmatic microstructures are preserved inside the pluton and solid-state, high-temperature deformation features are ubiquitous at its periphery. The presence of steeply plunging lineations in the pluton of Kouare and its adjacent host-rocks suggests that large volumes of granitic magmas became crystallized while they were ascending through the crust that was softened and steepened close to the contact. Around Kouare, the foliation in the host tonalites conforms with a map-scale, Z-shaped fold in between NNE-trending shear zones, implying a bulk clockwise rotation of the material contained in-between the shear zones, including the emplacing pluton. Regionally, the Fada N'Gourma area is concluded to result from NW-shortening associated with transcurrent shearing and vertical transfer of granitic magmas. This study concludes that the ˜2200 Myears old juvenile crust of Burkina Faso was brittle before the intrusion of the biotite-granites, became softened close to them and that gravity-driven and regional scale wrench tectonics were active together.

    Abstract In theory, the removal of user fees puts health services within reach of everyone, including the very poor. When Burkina Faso adopted the DOTS strategy for the control of tuberculosis, the intention was to provide free tuberculosis care. In 2007–2008, interviews were used to collect information from 242 smear-positive patients with pulmonary tuberculosis who were enrolled in the national tuberculosis control programme in six rural districts. The median direct costs associated with tuberculosis were estimated at 101 United States dollars (US$) per patient. These costs represented 23% of the mean annual income of a patient’s household. During the course of their care, three quarters of the interviewed patients apparently faced “catastrophic” health expenditure. Inadequacies in the health system and policies appeared to be responsible for nearly half of the direct costs (US$ 45 per patient). Although the households of patients developed coping strategies, these had far-reaching, adverse effects on the quality of lives of the households’ members and the socioeconomic stability of the households. Each tuberculosis patient lost a median of 45 days of work as a result of the illness. For a population living on or below the poverty line, every failure in health-care delivery increases the risk of “catastrophic” health expenditure, exacerbates socioeconomic inequalities, and reduces the probability of adequate treatment and cure. In Burkina Faso, a policy of “free” care for tuberculosis patients has not met with complete success. These observations should help define post-2015 global strategies for tuberculosis care, prevention and control. PMID:23599551

    Substantial healthcare expenses can impoverish households or push them further into poverty. In this paper, we examine the cost of obstetric care and the social and economic consequences associated with exposure to economic shocks up to a year following the end of pregnancy in Burkina Faso. Burkina Faso is a low-income country with poor health outcomes and a poorly functioning health system. We present an inter-disciplinary analysis of an ethnographic study of 82 women nested in a prospective cohort study of 1013 women. We compare the experiences of women who survived life-threatening obstetric complications ('near-miss' events) with women who delivered without complications in hospitals. The cost of emergency obstetric care was significantly higher than the cost of care for uncomplicated delivery. Compared with women who had uncomplicated deliveries, women who survived near-miss events experienced substantial difficulties meeting the costs of care, reflecting the high cost of emergency obstetric care and the low socioeconomic status of their households. They reported more frequent sale of assets, borrowing and slower repayment of debt in the year following the expenditure. Healthcare costs consumed a large part of households' resources and women who survived near-miss events continued to spend significantly more on healthcare in the year following the event, while at the same time experiencing continued cost barriers to accessing healthcare. In-depth interviews confirm that the economic burden of emergency obstetric care contributed to severe and long-lasting consequences for women and their households. The necessity of meeting unexpectedly high costs challenged social expectations and patterns of reciprocity between husbands, wives and wider social networks, placed enormous strain on everyday survival and shaped physical, social and economic well-being in the year that followed the event. In conclusion, we consider the implications of our findings for financing

    Enteric viruses are a major cause of diarrhea in children, especially those under five years old. Identifying the viral agents is critical to the development of effective preventive measures. This study aimed to determine the prevalence and genetic diversity of common enteric viruses in children under five years old in Burkina Faso. Stool samples from children with (n = 263) and without (n = 50) diarrhea disorders were collected in Ouagadougou, Burkina Faso from November 2011 to September 2012. Rotavirus, norovirus, sapovirus, astrovirus, adenovirus and Aichivirus A were detected using real-time or end-point (RT-)PCR. Rotavirus strains were G and P genotyped by multiplex RT-PCR and other viral strains were characterized by sequencing of viral subgenomic segements. At least one viral agent was detected in 85.6% and 72% of the symptomatic and asymptomatic patients, respectively. Rotavirus (63.5%), adenovirus (31.2%) and genogroup II norovirus (18.2%) were the most prevalent viruses in symptomatic patients, but only rotavirus and genogroup II norovirus were significantly associated with diarrhea (OR: 7.9, 95%CI: 3.7–17; OR: 3.5, 95%CI: 1–11.7, respectively). Sapovirus (10.3%), astrovirus (4.9%), genogroup I norovirus (2.7%) and Aichivirus A (0.8%) were less prevalent. The predominant genotype of rotavirus was G9P[8] (36.5%), and the predominant norovirus strain was GII.4 variant 2012 (71.4%). Among sapovirus, the genogroup II (87.5%) predominated. Astrovirus type 1 (41.7%) was the most frequent astrovirus identified. Aichivirus A belonged to the three genotypes (A, B and C). Enteric adenoviruses type 40 and 41 were identified in 10.2% and 5.1% respectively. Several cases of co-infections were detected. The results highlight the high prevalence and the high diversity of enteric viruses in Burkinabe children. PMID:27092779

    Trypanosomosis is an important disease affecting humans as well as animals. It remains a big constraint to livestock productions in tropical areas. The objective of this study was to assess the importance of trypanosomosis among cattle diseases in Burkina Faso, mainly in tsetse-challenged areas, and to capture information on how farmers apply available methods for controlling the disease. A survey has been carried out in 29 villages of Burkina Faso in three regions (north, southwest, and west regions). One hundred and thirty-four cattle breeders were interviewed individually with a questionnaire. The results indicate that among the 16 diseases mentioned by cattle breeders, trypanosomosis is the most important one in tsetse-challenged areas. Overall, 76.12 % of the breeders mentioned it as the most important disease, while 54.55 % of the farmers in the southwest region and 70.91 % of the farmers in the west region ranked it as a priority disease. Chemoprophylaxis/chemotherapy is widely used as a control method. Isometamidium chloride and diminazene aceturate were used by 53.49 and 46.52 % of the responders, respectively. Among farmers, 85.55 % ranked diminazene aceturate as the less efficient while 14.45 % ranked isometamidium chloride as the most efficient trypanocid. Trypanocidal drug quality and drug resistance were raised as a major concern by 30.77 and 50 % of the respondents, respectively. According to them, zebu cattle are more susceptible to trypanosomosis than taurine Baoule cattle and their crosses with zebu, emphasizing that crossing susceptible breeds with trypanotolerant ones, could be used as part of an integrated control strategy.

    This study investigated the hygienic status and prevalence of Salmonella and Escherichia coli in retail meat sold at open markets in Ouagadougou, Burkina Faso. A total of 150 samples of beef meat (n = 45), beef intestine (n = 45), mutton (n = 30), and chicken (n = 30) were collected from four local markets for investigation. The prevalence of Salmonella enterica subsp. enterica was 9.3%, and six serotypes, all previously unreported in Burkina Faso, were identified: Derby, Tilene, Hato, Bredeney, Agona, and Senftenberg. Most of the Salmonella isolates were sensitive to the 12 antimicrobial drugs tested. The prevalence of E. coli was 100% in all the meat types. An assessment of hygiene practices for the production, transportation, display, and vending of the meat revealed unhygienic conditions. Meat sellers had a low education level and poor knowledge of foodborne pathogens and their transmission routes. The findings showed that foodstuff handlers were in dire need of education about safe food handling practices.

    Background Female Sex workers (FSW) are important in driving HIV transmission in West Africa. The Yerelon clinic in Burkina Faso has provided combined preventative and therapeutic services, including anti-retroviral therapy (ART), for FSWs since 1998, with evidence suggesting it has decreased HIV prevalence and incidence in this group. No data exists on the costs of such a combined prevention and treatment intervention for FSW. This study aims to determine the mean cost of service provision per patient year for FSWs attending the Yerelon clinic, and identifies differences in costs between patient groups. Methods Field-based retrospective cost analyses were undertaken using top-down and bottom-up costing approaches for 2010. Expenditure and service utilisation data was collated from primary sources. Patients were divided into groups according to full-time or occasional sex-work, HIV status and ART duration. Patient specific service use data was extracted. Costs were converted to 2012 US$. Sensitivity analyses considered removal of all research costs, different discount rates and use of different ART treatment regimens and follow-up schedules. Results Using the top-down costing approach, the mean annual cost of service provision for FSWs on or off ART was US$1098 and US$882, respectively. The cost for FSWs on ART reduced by 29%, to US$781, if all research-related costs were removed and national ART monitoring guidelines were followed. The bottom-up patient-level costing showed the cost of the service varied greatly across patient groups (US$505–US$1117), primarily due to large differences in the costs of different ART regimens. HIV-negative women had the lowest annual cost at US$505. Conclusion Whilst FSWs may require specialised services to optimise their care and hence, the public health benefits, our study shows that the cost of ART provision within a combined prevention and treatment intervention setting is comparable to providing ART to other population groups

    The bioaccumulation and biomagnification of mercury (Hg) and selenium (Se) were investigated in sub-tropical freshwater food webs from Burkina Faso, West Africa, a region where very few ecosystem studies on contaminants have been performed. During the 2010 rainy season, samples of water, sediment, fish, zooplankton, and mollusks were collected from three water reservoirs and analysed for total Hg (THg), methylmercury (MeHg), and total Se (TSe). Ratios of δ13C and δ15N were measured to determine food web structures and patterns of contaminant accumulation and transfer to fish. Food chain lengths (FCLs) were calculated using mean δ15N of all primary consumer taxa collected as the site-specific baseline. We report relatively low concentrations of THg and TSe in most fish. We also found in all studied reservoirs short food chain lengths, ranging from 3.3 to 3.7, with most fish relying on a mixture of pelagic and littoral sources for their diet. Mercury was biomagnified in fish food webs with an enrichment factor ranging from 2.9 to 6.5 for THg and from 2.9 to 6.6 for MeHg. However, there was no evidence of selenium biomagnification in these food webs. An inverse relationship was observed between adjusted δ15N and log-transformed Se:Hg ratios, indicating that Se has a lesser protective effect in top predators, which are also the most contaminated animals with respect to MeHg. Trophic position, carbon source, and fish total length were the factors best explaining Hg concentration in fish. In a broader comparison of our study sites with literature data for other African lakes, the THg biomagnification rate was positively correlated with FCL. We conclude that these reservoir systems from tropical Western Africa have low Hg biomagnification associated with short food chains. This finding may partly explain low concentrations of Hg commonly reported in fish from this area. PMID:25875292

    Molecular identification of fungal taxa commonly transmitted through seeds of sorghum in Western Africa is lacking. In the present study, farm-saved seeds, collected from four villages in Northern Burkina Faso, were surface sterilized and the distribution of fungal DNA in seeds and seven-day-old seedlings was analyzed by 18S ribosomal DNA (rDNA) amplicon sequencing. More than 99% of the fungal rDNA was found to originate from ascomycetes. The distribution of ascomycetes at species level was subsequently analyzed by barcoding of ITS2 rDNA. Eighteen Operational Taxonomic Units (OTUs) were identified from seedlings, compared to 29 OTUs from seeds. The top-eight most abundant ascomycete OTUs from seedlings were annotated as: Epicoccum sorghinum, Fusarium thapsinum, four different Curvularia spp., Exserohilum rostratum and Alternaria longissima. These OTUs were also present in amplicons from seed samples collected in Central Burkina Faso confirming a common occurrence. E. sorghinum was highly predominant in seedlings both measured by DNA analysis and by isolation. The dominance of E. sorghinum was particularly strong in roots from poorly growing seedlings. Pathogenicity of E. sorghinum isolates was compared to F. thapsinum by inoculation to seeds in vitro. Both fungal species caused significant inhibition of seedling growth (P<0.001) and Koch's postulates were fulfilled. Extensive, dark necrosis in roots was a typical symptom of E. sorghinum, whereas wilting of leaves was caused primarily by F. thapsinum. This study provides the first molecular approach to characterize the seedling mycoflora of sorghum in Western Africa and suggests E. sorghinum as a common root pathogen. PMID:27524652

    Background. A group A meningococcal (MenA) conjugate vaccine, PsA-TT (MenAfriVac), was introduced in Burkina Faso via mass campaigns between September and December 2010, targeting the 1- to 29-year-old population. This study describes specific antibody titers in the general population 11 months later and compares them to preintroduction data obtained during 2008 using the same protocol. Methods. During October–November 2011, we recruited a representative sample of the population of urban Bobo-Dioulasso aged 6 months to 29 years, who underwent standardized interviews and blood draws. We assessed anti-MenA immunoglobulin G (IgG) concentrations (n = 200) and, using rabbit complement, serum bactericidal antibody (SBA) titers against 2 group A strains: reference strain F8238 (SBAref) (n = 562) and strain 3125 (SBA3125) (n = 200). Results. Among the 562 participants, 481 (86%) were aged ≥23 months and had been eligible for the PsA-TT campaign. Among them, vaccine coverage was 86.3% (95% confidence interval [CI], 82.7%–89.9%). Prevalence of putatively protective antibodies among vaccine-eligible age groups was 97.3% (95% CI, 95.9%–98.7%) for SBAref titers ≥128, 83.6% (95% CI, 77.6%–89.7%) for SBA3125 ≥128, and 84.2% (95% CI, 78.7%–89.7%) for anti-MenA IgG ≥2 µg/mL. Compared to the population aged 23 months to 29 years during 2008, geometric mean titers of SBAref were 7.59-fold higher during 2011, 51.88-fold for SBA3125, and 10.56-fold for IgG. Conclusions. This study shows high seroprevalence against group A meningococci in Burkina Faso following MenAfriVac introduction. Follow-up surveys will provide evidence on the persistence of population-level immunity and the optimal vaccination strategy for long-term control of MenA meningitis in the African meningitis belt.

    The first cases of AIDS in Burkina Faso were reported in 1986. During the past ten years, there have been several types of research conducted in Burkina Faso in the field of social sciences, including KABP, focus groups, and ethnographic studies. This article reviews approximately 100 publications and presents the results most relevant to prevention. Although general knowledge of the disease, its transmission and means of protection has improved, part of the population remains poorly informed; erroneous ideas remain prevalent and certain concepts, for example asymptomatic infection, are ignored. Young women in rural areas have the poorest knowledge. Understanding the information is conditioned by underlying perceptions of blood and physiology, the "components of the person", pre-existent and sexually transmitted diseases, and modes of transmission. Research on sexuality has elucidated the age at which individuals become sexually active, and paramatrimonial practices. The prevalence of STD is high. STD are mostly treated by traditional practitioners or by automedication. Family planning is insufficiently developed. AIDS prevention should be integrated into wider considerations of reproductive health. The popular perception that "Others" are responsible for bringing AIDS into the country has often been reinforced by health messages. Consequently, people do not sufficiently consider themselves vulnerable to HIV infection. The populations that are most vulnerable, for various reasons that have been analysed, include young girls and women, married women, prostitutes, truck drivers, and young men from rural areas. The message "Fidelity or condom" has been widely used. However, it has hindered the generalisation of the use of condoms, because asking for a condom consequently implies distrust of the partner. The interpretation of fidelity is diverse, and many people who choose this means of prevention believe erroneously that they are protected. Studies of the social

    Averting women's pregnancy-related death is today recognised as an international health and development priority. Maternal survival is, in this sense, a success story. There is, however, little research into what happens to the women who survive the severe obstetric complications that are the main causes of maternal mortality. This paper examines findings from repeated in-depth interviews with 64 women who survived a clinically defined 'near-miss.' These interviews were conducted as part of a prospective longitudinal study of women who 'nearly died' of pregnancy-related complications in Burkina Faso, a poor country in West Africa. Drawing on sociological and anthropological perspectives that consider the defining characteristics of 'loss' to be social as much as biomedical, the paper seeks to understand loss as disruption of familiar forms and patterns of life. Women's accounts of their lives in the year following the near-miss event show that such events are not only about blood loss, seizures or infections, but also about a household crisis for which all available resources were mobilised, with a train of physical, economic and social consequences. The paper argues that near-miss events are characterised by the near-loss of a woman's life, but also frequently by the loss of the baby and by further significant disruptions in three overlapping dimensions of women's lives. These include disruption of bodily integrity through injury, ongoing illness and loss of strength and stamina; disruption of the household economy through high expenditure, debts and loss of productive capacity; and disruption of social identity and social stability. Maternal health policy needs to be concerned not only with averting the loss of life, but also with preventing or ameliorating others losses set in motion by an obstetric crisis.

    Seasonal malaria chemoprevention (SMC), with regular use of amodiaquine plus sulfadoxine-pyrimethamine (AQ/SP) during the transmission season, is now a standard malaria control measure in the Sahel subregion of Africa. Another strategy under study is SMC with dihydroartemisinin plus piperaquine (DP). Plasmodium falciparum single nucleotide polymorphisms (SNPs) in P. falciparum crt (pfcrt), pfmdr1, pfdhfr, and pfdhps are associated with decreased response to aminoquinoline and antifolate antimalarials and are selected by use of these drugs. To characterize selection by SMC of key polymorphisms, we assessed 13 SNPs in P. falciparum isolated from children aged 3 to 59 months living in southwestern Burkina Faso and randomized to receive monthly DP or AQ/SP for 3 months in 2009. We compared SNP prevalence before the onset of SMC and 1 month after the third treatment in P. falciparum PCR-positive samples from 120 randomly selected children from each treatment arm and an additional 120 randomly selected children from a control group that did not receive SMC. The prevalence of relevant mutations was increased after SMC with AQ/SP. Significant selection was seen for pfcrt 76T (68.5% to 83.0%, P = 0.04), pfdhfr 59R (54.8% to 83.3%, P = 0.0002), and pfdhfr 108N (55.0% to 87.2%, P = 0.0001), with trends toward selection of pfmdr1 86Y, pfdhfr 51I, and pfdhps 437G. After SMC with DP, only borderline selection of wild-type pfmdr1 D1246 (mutant; 7.7% to 0%, P = 0.05) was seen. In contrast to AQ/SP, SMC with DP did not clearly select for known resistance-mediating polymorphisms. SMC with AQ/SP, but not DP, may hasten the development of resistance to components of this regimen. (This study has been registered at ClinicalTrials.gov under registration no. NCT00941785.).

    Background Taenia solium, a zoonotic infection transmitted between humans and pigs, is considered an emerging infection in Sub-Saharan Africa, yet individual and community-level factors associated with the human infection with the larval stages (cysticercosis) are not well understood. This study aims to estimate the magnitude of association of individual-level and village-level factors with current human cysticercosis in 60 villages located in three Provinces of Burkina Faso. Methodology/Principal Findings Baseline cross-sectional data collected between February 2011 and January 2012 from a large community randomized-control trial were used. A total of 3609 individuals provided serum samples to assess current infection with cysticercosis. The association between individual and village-level factors and the prevalence of current infection with cysticercosis was estimated using Bayesian hierarchical logistic models. Diffuse priors were used for all regression coefficients. The prevalence of current cysticercosis varied across provinces and villages ranging from 0% to 11.5%. The results obtained suggest that increased age, being male and consuming pork as well as a larger proportion of roaming pigs and percentage of sand in the soil measured at the village level were associated with higher prevalences of infection. Furthermore, consuming pork at another village market had the highest increased prevalence odds of current infection. Having access to a latrine, living in a household with higher wealth quintiles and a higher soil pH measured at the village level decreased the prevalence odds of cysticercosis. Conclusions/Significance This is the first large-scale study to examine the association between variables measured at the individual-, household-, and village-level and the prevalence odds of cysticercosis in humans. Factors linked to people, pigs, and the environment were of importance, which further supports the need for a One Health approach to control

    Monitoring turbidity and Surface Suspended Sediment Concentration (SSSC) of inland waters is essential to address several important issues: erosion, sediment transport and deposition throughout watersheds, reservoir siltation, water pollution, human health risks, etc. This is especially important in regions with limited conventional monitoring capacities such as West Africa. In this study, we explore the use of Moderate Resolution Imaging Spectroradiometer data (MODIS, MOD09Q1 and MYD09Q1 products, red (R) and near infrared (NIR) bands) to monitor turbidity and SSSC for the Bagre Reservoir in Burkina Faso. High values ​​of these parameters associated with high spatial and temporal variability potentially challenge the methodologies developed so far for less turbid waters. Field measurements (turbidity, SSSC, radiometry) are used to evaluate different radiometric indices. The NIR/R ratio is found to be the most suited to retrieve SSSC and turbidity for both in-situ spectoradiometer measurements and satellite reflectance from MODIS. The spatio temporal variability of MODIS NIR/R together with rainfall estimated by the Tropical Rainforest Measuring Mission (TRMM) and altimetry data from Jason-2 is analyzed over the Bagre Reservoir for the 2000-2015 period. It is found that rain events of the early rainy season (February-March) through mid-rainy season (August) are decisive in triggering turbidity increase. Sediment transport is observed in the reservoir from upstream to downstream between June and September. Furthermore, a significant increase of 19% in turbidity values is observed between 2000 and 2015, mainly for the July to December period. It is especially well marked for August, with the central and downstream areas showing the largest increase. The most probable hypothesis to explain this evolution is a change in land use, and particularly an increase in the amount of bare soils, which enhances particle transport by runoff.

    Soil and water samples were collected from a watershed in Burkina Faso where illegal artisanal gold extraction using cyanidation occurs. The samples were used to evaluate cyanide contamination and the presence of cyanide degrading bacteria (CDB). Free cyanide (F-CN) was detected in all samples, with concentrations varying from 0.023 to 0.9 mg kg(-1), and 0.7-23 μg L(-1) in the soil and water samples, respectively. Potential CDB also were present in the samples. To test the effective F-CN degradation capacity of the isolated CDB species, the species were cultivated in growth media containing 40, 60 or 80 mg F-CN L(-1), with or without nutrients, at pH 9.5 and at room temperature. More than 95% of F-CN was degraded within 25 h, and F-CN degradation was associated with bacterial growth and ammonium production. However, initial concentrations of F-CN higher than 100 mg L(-1) inhibited bacterial growth and cyanide degradation. Abiotic tests showed that less than 3% of F-CN was removed by volatilization. Thus, the degradation of F-CN occurred predominately by biological mechanisms, and such mechanisms are recommended for remediation of contaminated soil and water. The bacteria consortium used in the experiment described above exist in a Sahelian climate, which is characterized by a long hot and dry season. Because the bacteria are already adapted to the local climate conditions and show the potential for cyanide biodegradation, further applicability to other contaminated areas in West Africa, where illegal gold cyanidation is widespread, should be explored.

    The vaginal swabs among HIV-positive women in Africa often revealed opportunistic infections such as human Papillomavirus (HPV) and Mycoplasma that induce respectively cervix cancer and diseases such as vaginosis, abortions, infertility in through salpingitis. The purposes of this study were to: (1) seek for, the prevalence of pathogens such as HPV and Mycoplasma; (2) characterize the strains of HPV and estimate their prevalence; (3) identify among these women, those who were co-infected by these pathogens in order to cure them. From February 2009 to January 2010, 156 HIV-positive women attending our medical centers and aged from 19-45 years (mean age 33.65 +/- 5.75 years) had voluntarily accepted vaginal specimen's tests. PCR, ELISA and molecular hybridization were used for the identification and characterization of these pathogens. The results revealed the presence of Mycoplasma and HPV in 25.64 and 58.33% cases, respectively. The following HPV genotypes and the following prevalence were recorded: HPV-50'S (24.11%), HPV-18 (21.28%), HPV-30'S (18.44%) and HPV-16 (5.67%). The study also enable the identification of co-infections such as HPV-18 strains with HPV-30'S (5.67%) and HPV-30'S with HPV-50'S (3.55%). Other germs infecting the female genital tract including Candida albicans (20.51%), Escherichia coli (12.18%), Treponema pallidum (3.85%), Streptococcus agalactiae (3.21%) and Staphylococcus aureus (1.92%) were isolated. This preliminary research work showed the incidence of several genital pathogens, this could be a springboard for nationwide epidemiological study on HPV strains circulating in Burkina Faso.

    Neisseria meningitidis is a major cause of bacterial meningitis and a considerable health problem in the 25 countries of the 'African Meningitis Belt' that extends from Senegal in West Africa to Ethiopia in the East. Approximately 80% of cases of meningococcal meningitis in Africa have been caused by strains belonging to capsular serogroup A. After the introduction of a serogroup A conjugate polysaccharide vaccine, MenAfriVac (™), that began in December 2010, the incidence of meningitis due to serogroup A has markedly declined in this region. Currently, serogroup W of N. meningitidis accounts for the majority of cases. Vaccines based on sub-capsular antigens, such as Generalized Modules for Membrane Antigens (GMMA), are under investigation for use in Africa. To analyse the antigenic properties of a serogroup W wave of colonisation and disease, we investigated the molecular diversity of the protein vaccine antigens PorA, Neisserial Adhesin A (NadA), Neisserial heparin-binding antigen (NHBA) and factor H binding protein (fHbp) of 31 invasive and carriage serogroup W isolates collected as part of a longitudinal study from Ghana and Burkina Faso between 2003 and 2009. We found that the isolates all expressed fHbp variant 2 ID 22 or 23, differing from each other by only one amino acid, and a single PorA subtype of P1.5,2. Of the isolates, 49% had a functional nhbA gene and 100% had the nadA allele 3, which contained the insertion sequence IS1301 in five isolates. Of the W isolates tested, 41% had high fHbp expression when compared with a reference serogroup B strain, known to be a high expresser of fHbp variant 2. Our results indicate that in this collection of serogroup W isolates, there is limited antigenic diversification over time of vaccine candidate outer membrane proteins (OMP), thus making them promising candidates for inclusion in a protein-based vaccine against meningococcal meningitis for Africa.

    African animal trypanosomosis is a major obstacle to the development of more efficient and sustainable livestock production systems in West Africa. Riverine tsetse species such as Glossina palpalis gambiensis Vanderplank are their major vectors. A wide variety of control tactics is available to manage these vectors, but their elimination will only be sustainable if control is exercised following area-wide integrated pest management (AW-IPM) principles, i.e. the control effort is targeting an entire tsetse population within a circumscribed area. In the present study, genetic variation at microsatellite DNA loci was used to examine the population structure of G. p. gambiensis inhabiting two adjacent river basins, i.e. the Comoé and the Mouhoun River basins in Burkina Faso. A remote sensing analysis revealed that the woodland savannah habitats between the river basins have remained unchanged during the last two decades. In addition, genetic variation was studied in two populations that were separated by a man-made lake originating from a dam built in 1991 on the Comoé. Low genetic differentiation was observed between the samples from the Mouhoun and the Comoé River basins and no differentiation was found between the samples separated by the dam. The data presented indicate that the overall genetic differentiation of G. p. gambiensis populations inhabiting two adjacent river basins in Burkina Faso is low (F(ST)=0.016). The results of this study suggest that either G. p. gambiensis populations from the Mouhoun are not isolated from those of the Comoé, or that the isolation is too recent to be detected. If elimination of the G. p. gambiensis population from the Mouhoun River basin is the selected control strategy, re-invasion from adjacent river basins may need to be prevented by establishing a buffer zone between the Mouhoun and the other river basin(s).

    In order to assess the human immunodeficiency virus (HIV) prevalence among teachers in Burkina Faso, we carried out a national survey in 336 primary and secondary schools from urban and rural areas. Among 2088 teachers who agreed to participate, 1498 (71.7%) provided urine for HIV testing. The crude prevalence of HIV among teachers was 2.8% (95% confidence interval [CI]: 2.0-3.6), with no difference between teachers from primary schools (2.9%, 95%CI: 2.1-4.0) and those from secondary schools (2.5%, 95%CI: 0.5-4.5). Age- and area-standardized HIV prevalence was 1.0% (95%CI: 0.4-1.2) in male teachers, 2.5 times lower than among men in the general population (as assessed from a concomitant Demographic Health Survey), and it was 3.5% (95%CI: 2.5-5.2) in female teachers, 1.7 times higher than in Demographic Health Survey women. This finding calls for the implementation of specific HIV prevention programmes in the education sector targeting women more specifically.

    This study examined the association between food insecurity, determined by a modified version of the U.S. Household Food Security Survey Module (US HFSSM), and total daily per capita (DPC) consumption (measured as household expenditures) in Bolivia, Burkina Faso, and the Philippines. Household food insecurity was determined by an adapted 9-item US HFSSM version. A short version of the World Bank's Living Standards Measurement Study (LSMS) consumption module measured household expenditures. Focus groups were used to adapt the survey instrument to each local context. The sample (n approximately 330 per country) includes residents of urban and rural areas. A 12-month food expenditure aggregate was generated as part of the total household expenditures calculation. DPC food expenditure, which represented over 60% of the total household consumption, as well as expenditures on specific food groups correlated with food insecurity both as a continuous Food Insecurity Score (FinSS) and a tricategorical food insecurity status variable. ANOVA and regression analysis were executed adjusting for social and demographic covariates. Food-secure households have significantly higher (P < 0.05) total DPC food expenditures as well as expenditures on animal source foods, vegetables, and fats and oils than moderately and severely food-insecure households. The results offer evidence that the US HFSSM is able to discriminate between households at different levels of food insecurity status in diverse developing world settings.

    In the early 1980s, the situation on the northern part of the Central Plateau of Burkina Faso was characterized by expanding cultivation on lands marginal to agriculture, declining rainfall, low and declining cereal yields, disappearing and impoverishing vegetation, falling ground-water levels and strong outmigration. This crisis situation provoked two reactions. Farmers, as well as technicians working for non-governmental organizations, started to experiment in improving soil and water conservation (SWC) techniques. When these experiments proved successful, donor agencies rapidly designed SWC projects based on simple, effective techniques acceptable to farmers. A study looked at the impact of SWC investments in nine villages and identified a number of major impacts, including: significant increases in millet and sorghum yields since the mid-1980s, cultivated fields treated with SWC techniques have more trees than 10-15 years ago, but the vegetation on most of the non-cultivated areas continues to degrade, greater availability of forage for livestock, increased investment in livestock by men and women and a beginning change in livestock management from extensive to semi-intensive methods, improved soil fertility management by farmers, locally rising ground-water tables, a decrease in outmigration and a significant reduction in rural poverty. Finally, data are presented on the evolution of land use in three villages between 1968 and 2002. ?? 2005 Elsevier Ltd. All rights reserved.

    In the eastern part of Burkina-Faso, the riverine tsetse fly, Glossina tachinoides Westwood, transmits African animal trypanosomosis that constitute a major constraint to sub-Saharan agriculture. To organize an efficient vector control campaign against this vector, it is crucial to identify and target isolated populations in order to prevent any risk of reinvasion. Previous entomological data using traps in this part of the country have suggested that G. tachinoides has now become discontinuously distributed with a western and an eastern tsetse belt. In this paper, we studied population genetics on G. tachinoides trapped in two sites, separated by 150 kms, on the western and eastern sides of this "gap". We found that a significant differentiation does exist between the two sites and that it is fairly above than what was expected given the geographic distance. A comparison between observed and expected differentiation allowed estimating that the total separation between these two sites could have occurred around 10 years ago (i.e. between 1 and 21 years), which is in line with the dates of environmental changes that occurred in this area. This result will help the national PATTEC project to organize the tsetse eradication in this area.

    Within relatively small areas, there exist high spatial variations of mortality between villages. In rural Burkina Faso, with data from 1993 to 1998, clusters of particularly high child mortality were identified in the population of the Nouna Health and Demographic Surveillance System (HDSS), a member of the INDEPTH Network. In this paper, we report child mortality with respect to temporal trends, spatial clustering and disparity in this HDSS from 1993 to 2012. Poisson regression was used to describe village-specific child mortality rates and time trends in mortality. The spatial scan statistic was used to identify villages or village clusters with higher child mortality. Clustering of mortality in the area is still present, but not as strong as before. The disparity of child mortality between villages has decreased. The decrease occurred in the context of an overall halving of child mortality in the rural area of Nouna HDSS between 1993 and 2012. Extrapolated to the Millennium Development Goals target period 1990-2015, this yields an estimated reduction of 54%, which is not too far off the aim of a two-thirds reduction.

    Conidiobolomycosis is a deep, rare mycosis, due to Conidiobolus coronatus which is a saprophyte of vegetation in decomposition. We report one case in Burkina Faso. A 17 years old man, shepherd, consulted for tumefactions on the face. It could date back insidiously to a traumatism, one year before. A month later some painless tumefactions appeared on the cheekbone, the right eyelid, the nose with epistaxis. The upper lip then the lower one had swollen. Dermatological exam revealed multiple, painless, hard, sub-cutaneous swellings, affecting the cheekbone, the eyelids, the root and the ala of the nose. This tumefaction sometimes adhered to underlying tissues and to the overlying skin, sometimes mobile; painless and hard swelling of the two lips was also noted. ENT exam showed an inflammation of the nasal mucous without ulceration and the permeability of the nasal tracts was subnormal. The cephalic tomodensitometry showed a thickness of the soft tissues of the lips and the nose with an infectious feature associated to a pansinusitis without bone lesion. Histology was in favour of conidiobolomycosis. The patient was treated with fluconazole and the swelling progressively disappeared. Conidiobolomycosis is a disease generally reported in some humid tropical countries. It begins in the nasal cavities leading then to a nasal obstruction. This case was singular by the fact it happened in a dry Sudano-Sahelian climate and by its clinical features. PMID:18431999

    The aim of this study is to demonstrate the impact of increased access to primary care on provider costs in the rural health district of Nouna, Burkina Faso. This study question is crucial for health care planning in this district, as other research work shows that the population has a higher need for health care services. From a public health perspective, an increase of utilisation of first-line health facilities would be necessary. However, the governmental budget that is needed to finance improved access was not known. The study is based on data of 2004 of a comprehensive provider cost information system. This database provides us with the actual costs of each primary health care facility (Centre de Santé et de Promotion Sociale, CSPS) in the health district. We determine the fixed and variable costs of each institution and calculate the average cost per service unit rendered in 2004. Based on the cost structure of each CSPS, we calculate the total costs if the demand for health care services increased. We conclude that the total provider costs of primary care (and therefore the governmental budget) would hardly rise if the coverage of the population were increased. This is mainly due to the fact that the highest variable costs are drugs, which are fully paid for by the customers (Bamako Initiative). The majority of other costs are fixed. Consequently, health care reforms that improve access to health care institutions must not fear dramatically increasing the costs of health care services. PMID:18197447

    In Burkina Faso, the management of TB/HIV co-infection presents a challenge for policy-makers and the health-care system, with its psychological, sociocultural and biomedical issues. The purpose of this paper is to describe the concerns caused by this co-infection and propose a management strategy for these patients. These findings result from a qualitative socio-anthropological study during a public health project in three health districts from 2006 to 2008 and from the observation of care practices in health centres. Patients face a double burden: the negative social image of both diseases and complicated difficult treatment. They deal with problems of social integration, with their social relations impaired by humiliation and marginalisation. The painful experience of daily doses of antiretroviral and anti-TB drugs creates bitterness against drugs, aggravated sometimes by apparently capricious care. In addition to economic insecurity, these chronically ill patients face social stigma and marginalisation, all damaging to their self-esteem.

    In Burkina Faso, Glossina palpalis gambiensis Vanderplank and G. tachinoides Westwood (Diptera: Glossinidae) are the main cyclic vectors of trypanosomiasis. The vegetation type along river banks is an important factor determining the distribution and abundance of these tsetse. The following work investigated the relation between the plant species present (including the disturbance level) and tsetse distribution and abundance, using three ecotypes, described by P.C. Morel in 1978. These were the Guinean, Sudano-Guinean and Sudanese gallery forests. In the Mouhoun River basin, these three ecotypes are found successively from upstream to downstream. Berlinia grandiflora, Syzygium guineense and Cola laurifolia and finally Acacia seyal and Mitragyna inermis were the best indicators for the Guinean, Sudano-Guinean and Sudanese gallery forest ecotypes, respectively, as suggested by Morel. However, other species such as Pterocarpus santalinoides and Mimosa pigra were not ecotype specific. Trap catches confirmed that G. palpalis and G. tachinoides are predominant in Guinean and Sudanese gallery forests, respectively, and that both species are well represented in the Sudano-Guinean ecotype. Tsetse densities dropped significantly in disturbed Sudano-Guinean and Sudanese gallery forest sites. However, this was not the case for both species in Guinean or for G. tachinoides in half-disturbed Sudanese gallery forest sites, confirming their high resilience to human-made changes. The importance of a detailed consideration of riverine ecotypes when predicting tsetse densities is discussed.

    OBJECTIVES: To determine whether a large, 3-year hygiene promotion programme in Bobo-Dioulasso, Burkina Faso, was effective in changing behaviours associated with the spread of diarrhoeal diseases. The programme was tailored to local customs, targeted specific types of behaviour, built on existing motivation for hygiene, and used locally appropriate channels of communication. METHODS: Two population surveys recorded the coverage of the programme among target audiences (mothers of children aged 0-35 months). Four surveys were carried out: three prior to the programme and one in 1998 (after the programme had been running for 3 years), using structured observation of hygiene behaviours in the participants' homes to document changes in target behaviours. FINDINGS: After the programme had run for 3 years, three-quarters of the mothers targeted had had contact with programme activities. Half could cite the two main messages of the programme correctly. Although the safe disposal of children's stools changed little between 1995 and 1998 (80% pre-intervention, 84% post-intervention), hand-washing with soap after cleaning a child's bottom rose from 13% to 31%. The proportion of mothers who washed their hands with soap after using the latrine increased from 1% to 17%. CONCLUSION: Hygiene promotion programmes can change behaviour and are more likely to be effective if they are built on local research and use locally appropriate channels of communication repeatedly and for an extended time.

    Following the sociopolitical unrest that occurred in Ivory Coast in 2002, 360,000 Burkinabe immigrants returned to Burkina Faso that was the epicenter of sleeping sickness last century and is now thought to be free of autochthonous transmission. The purpose of this study was to determine if the massive return of immigrants from human African trypanosomiasis (HAT) endemic areas of Ivory Coast to areas in Burkina Faso where the vector (tsetse fly) is currently present could lead to re-emergence of the disease. Risk areas for re-emergence were identified taking into account the number of returning immigrants, history of the disease, and presence of tsetse flies. Based on these criteria, study was focused on two villages, i.e., Folonzo and Gbalara, located in southern Burkina Faso near the Ivory Coast border. Study in these two villages consisted of characterization of the population (repatriates or not, origin, ...) and medical surveys to assess the presence/absence of the disease. Departure of some returning immigrants from areas including sleeping sickness foci in Ivory Coast (e.g. center west) confirmed the potential risk of re-emergence of the disease. Although no case of sleeping sickness was diagnosed, several serologically positive people were identified and will be followed up. This study failed to demonstrate a clear-cut correlation between massive population movements due to war and reemergence of sleeping sickness. However, this study may have been timed too soon after the return of immigrants to detect reemergence of HAT that could require several years.

    The history of drug resistance to the previous antimalarial drugs, and the potential for resistance to evolve to Artemisinin-based combination therapies, demonstrates the necessity to set-up a good surveillance system in order to provide early warning of the development of resistance. Here we report a review summarizing the history of the surveillance of drug resistance that led to the policy change in Burkina Faso. The first Plasmodium falciparum Chloroquine-Resistance strain identified in Burkina Faso was detected by an in vitro test carried out in Koudougou in 1983. Nevertheless, no further cases were reported until 1987, suggesting that resistant strains had been circulating at a low prevalence before the beginning of the systematic surveillance system from 1984. We observed a marked increase of Chloroquine-Resistance in 2002-2003 probably due to the length of follow-up as the follow-up duration was 7 or 14 days before 2002 and 28 days from 2002 onwards. Therefore, pre-2002 studies have probably under-estimated the real prevalence of Chloroquine-Resistance by not detecting the late recrudescence. With a rate of 8.2% treatment failure reported in 2003, Sulfadoxine-Pyrimethamine was still efficacious for the treatment of uncomplicated malaria in Burkina Faso but this rate might rapidly increase as the result of its spreading from neighboring countries and due to its current use for both the Intermittent Preventive Treatment in pregnant women and Seasonal Malaria Chemoprophylaxis. The current strategy for the surveillance of the Artemisinin-based combination treatments resistance should build on lessons learnt under the previous period of 20 years surveillance of Chloroquine and Sulfadoxine-Pyrimethamine resistance (1994-2004). The most important aspect being to extend the number of sentinel sites so that data would be less patchy and could help understanding the dynamic of the resistance. PMID:27262953

    Farmers in Burkina Faso are among the most exposed to climate change/ climate variability, as their livelihoods are greatly linked to climate hazards. Rainfall and in some extent temperature are among the inputs farmers use to take decisions in their farming activities. A better understanding of factors that shape farmers' perceptions of climate change and decision to adapt farming practices is needed to take appropriate measures. In the current study farmers' perception of climate change and climate variability- specifically, changes in rainfall and temperature- were compared to historical recorded climate data. Primary data was collected through village focus-group surveys and household surveys. Nine Focus Group Discussions (FGDs) were conducted in the study areas' villages; 450 households were also selected randomly from three locations and sampled out through a multi-stage sampling procedure. Secondary data on the historical precipitation and temperature of Burkina Faso from 1960 to 2012 was obtained from the National Meteorological Service of Burkina Faso (DGM) and the Royal Netherlands Meteorological Institute. Standardized Precipitation Index (SPI) and temperature anomalies methodology have been used to assess anomalies in rainfall and temperature covering a period of 48 years, from 1964 to 2011; and Mann-Kendall test and Theil-Sen slope estimator to assess the significance of the trends and the Theil-Sen slope estimator is used to identify their magnitude. The analysis of farmers' perceptions of climate change indicates that most farmers perceived a declining trend of precipitation and an increasing trend of temperature in all areas. Results from recorded climate data's analysis, revealed contrasting evidence, while that farmers' perception of temperature match with historical data, their perception of rainfall evolution were not always corroboted by scientific evidence.

    Introduction Despite the universal recognition of unsafe abortion as a major public health problem, very little research has been conducted to document its precipitating factors in Burkina Faso. Our aim was to investigate the key determinants of induced abortion in a sample of women who sought postabortion care. Materials and methods A cross-sectional household survey was carried out from February to September 2012 in Ouagadougou, Burkina Faso. Data of 37 women who had had an induced abortion and 267 women who had had a spontaneous abortion were prospectively collected on sociodemographic characteristics, pregnancy and birth history, abortion experience, including previous abortion experience, and selected clinical information, including the type of abortion. A two-step regression analysis consisting of a univariate and a multivariate logistic regression was run on Stata version 11.2 in order to identify the key determinants of induced abortion. Results The findings indicated that 12% of all abortions were certainly induced. Three key factors were significantly and positively associated with the probability of having an induced abortion: whether the woman reported that her pregnancy was unwanted (odds ratio [OR] 10.45, 95% confidence interval [CI] 3.59–30.41); whether the woman reported was living in a household headed by her parents (OR 6.83, 95% CI 2.42–19.24); and if the woman reported was divorced or widowed (OR 3.47, 95% CI 1.08–11.10). On the contrary, being married was protective against induced abortion, with women who reported being married having an 83% (OR 0.17, CI 0.03–0.89) lower chance of having an induced abortion, even when the pregnancy was unwanted. Conclusion This study has identified three major determinants of induced abortion in Ouagadougou, Burkina Faso. Improved targeted programs on family planning counseling, methods of contraception, and availability of contraceptives should be widely promoted. PMID:24920938

    Smoking is a worldwide phenomenon and many studies have demonstrated that tobacco use is a risk factor for morbidity and mortality. We investigated aspects of the supply of, and demand for, tobacco in Burkina Faso, with a view to helping the public authorities design strategies to combat this phenomenon. We used data on the importation of tobacco and the making of cigarettes in Burkina Faso and carried out a survey of adolescents and young adults (n = 289) with a mean age of 20.9 years. In 1997, Burkina Faso imported 1,905, 214 metric tons of tobacco of all kinds, with a CAF value of 5,808, 905,269 CFA francs. In the survey, 30.7% of those interviewed said that they smoked. These individuals gave various reasons for their use of tobacco including imitating friends (38.6%) and personal liberty (14.1%). These young people were generally aware of the risks of tobacco use, but this did not deter them from smoking. In countries like Burkina Faso, which is faced with many challenges, controlling tobacco advertising and providing ways and means to help young people to stop smoking or to deter them from starting to smoke are of major importance for future public health.

    In 1998, researchers in Burkina Faso enrolled 300 women more or less involved in commercial sex work in an open cohort to determine whether adequate management of their sexually transmitted infections and exposure to well-designed, well-delivered, and plentiful communication for behaviour change (CBC) might reduce their vulnerability to HIV. In 2000, they observed that the non-professional sex workers (occasional or clandestine sex workers) were more difficult to reach, to mobilize and to keep involved in the project's different activities. This group was also infected at the same or higher rates than professional sex workers because they did not use condoms routinely. To accomplish the project objectives, they therefore chose to recruit more non-professional sex workers in the new cohort of 700 women. This social-anthropological study was conducted to help them to enrol young clandestine sex workers. The overall objective of this study was to understand the life of this category of sex workers and to identify strategic actors to reach them. Using a qualitative method, social anthropologists reviewed literature, identified and geo-referenced all local places suitable to encountering these women, obtained life stories from some of them and interviewed key informants and participants in the field. The results showed that in Bobo-Dioulasso (Burkina Faso): - most young women who are clandestine sex workers are Burkinabe, and girls entering the sex trade are increasingly young and increasingly uneducated; - most of them come from families with low capital (financial, cultural, or social). The parents' socioeconomic status (contextual poverty) results in unmet financial needs, which in turn exposes them to starting work early, including commercial sex work; - of all the income-generating activities available to unskilled young girls, commercial sex work is one of the most profitable and easily accessible; - in the three-fold context of an HIV epidemic, poverty, and

    Background Physical and chemical parameters of water in reservoirs can be affected by natural and manmade pollutants, causing damage to the aquatic life and water quality. However, the exact water quality considerations depend on what the water will be used for. Brick making, livestock watering, fisheries, irrigation and domestic uses all have their own specific water quality requirements. In turn, these uses impact on water quality. Methodology Water quality was assessed with a variety of methods in small multipurpose reservoirs in the São Francisco Basin in Brazil, Limpopo in Zimbabwe, Souss Massa in Morocco and Nakambé in Burkina Faso. In each case the first step was to select the reservoirs for which the water quality was to be monitored, then identify the main water uses, followed by a determination of key relevant water quality parameters. In addition, a survey was done in some cases to identify quality perceptions of the users. Samples were taken from the reservoir itself and related water bodies such as canals and wells where relevant. Results Accordingly in the four basins different methods gave different locally relevant results. In the Preto River in the Sao Francisco in Brazil small reservoirs are mainly used for irrigated agriculture. Chemical analysis of various small reservoirs showed that water quality was mainly influenced by geological origins. In addition there was nutrient inflow from surrounding areas of intensive agriculture with high fertilizer use. In the Limpopo basin in Zimbabwe small reservoirs are used for almost all community water needs. Plankton was selected as indicator and sampling was carried out in reservoirs in communal areas and in a national park. Park reservoirs were significantly more diversified in phytoplankton taxa compared to those in the communal lands, but not for zooplankton, though communal lands had the highest zooplankton abundance. In Souss Massa in Morocco a combination of perceptions and scientific water

    One of the most important challenges in addressing global health is for institutions to monitor and use research in policy-making. In low- and middle-income countries (LMICs), civil society organizations such as health professional associations can be key contributors to effective national health systems. However, there is little empirical data on their capacity to use research. This case study was used to gain insight into the factors that affect the knowledge translation performance of health professional associations in LMICs by describing the organizational elements and processes constituting capacity to use research, and examining the potential determinants of this capacity. Case study methodology was chosen for its flexibility to capture the multiple and often tacit processes within organizational routines. The Burkina Faso Public Health Association (ABSP) was studied, using in-depth, semi-structured interviews and key documents review. Five key dimensions that affect the association's capacity to use research to influence health policy emerged: organizational motivation; catalysts; organizational capacity to acquire and organizational capacity to transform research findings; moderating organizational factors. Also examined were the dissemination strategies used by ABSP and its abilities to enhance its capacity through networking, to advocate for more relevant research and to develop its potential role as knowledge broker, as well as limitations due to scarce resources. We conclude that a better understanding of the organizational capacity to use research of health professional associations in LMICs is needed to assess, improve and reinforce such capacity. Increased knowledge translation potential may leverage research resources and promote knowledge-sharing.

    Households are the main source of health care financing in Burkina Faso. The current system based on out-of-pocket health payments is a major cause of poverty. The purpose of this study was to contribute to the improvement of local health funding in Loumbila and throughout the country. A descriptive and analytical study was conducted among 271 household heads, 3 health committee members, the prefet (the top state official in the area), and the secretary general of the municipality between 25 June and 5 August 2010. A survey guide and questionnaires were used to collect data. The standard public health survey method was used to collect, process, analyze and discuss the results. The results of the survey indicate that 82.3% of the participating households were willing to contribute to the creation of a local health fund in the village. The study found that the average contribution rate of each household amounted to 9% of their annual income. The best periods for collecting funds are during the harvest season (in the case of farmers) or any favorable period (in the case of other households). The municipal committee will need to be responsible for managing and coordinating the municipal health fund. This requires the participation of the state, health districts, NGOs and other partners. The cost of effective treatment for the top ten priority diseases in the village in 2010 is estimated to be 4,011,300 FCFA. If all the households in the village were to contribute to the municipal health fund, the total amount of contributions would amount to 15,575,515 FCFA. Under this system, all households within the village can have access to essential drugs. The municipal health fund can also support municipal development boards to improve the independence and sustainability of the system. PMID:23043742

    Food insecurity is affecting an increasing number of urban poor in the developing world. Yet seasonal characteristics of food intakes have rarely been studied in West African cities. The objective of the present study was to assess the seasonality of the dietary dimension of household food security in Ouagadougou (Burkina Faso). In 2007, two sets of data were collected during the lean and post-harvest seasons, respectively, on a representative sample of 1056 households. At each season, two non-consecutive 24 h recalls were performed at the household level. Food prices were also recorded. Household food security was assessed by the household's mean adequacy ratio (MAR) for energy and eleven micronutrients. Changes in the MAR according to the season were analysed by mixed multivariate linear regression. Results showed that intakes of energy and of ten micronutrients were significantly lower during the lean season than during the post-harvest season, leading to a lower MAR in the lean season (49·61 v. 53·57, P < 0·0001). This was related to less frequent consumption and consumption of smaller amounts of vegetables and of foods prepared at home. Food security relied heavily on food expenses (P < 0·0001) and on the price of meat/fish (P = 0·026). Households with economically dependent adults (P = 0·021) and larger households (P < 0·0001) were the most vulnerable, whereas education (P = 0·030), social network (P = 0·054) and urban origin other than Ouagadougou (P = 0·040) played a positive role in food security. To achieve food security in Ouagadougou, access to micronutrient-dense foods needs to be ensured in all seasons. PMID:22017887

    Introduction Larval source management has contributed to malaria decline over the past years. However, little is known about the impact of larval control practices undertaken at the household level on malaria transmission. Methods The study was conducted in Kaya health district after the 2010 mass distribution of insecticide treated-nets and the initiation of malaria awareness campaigns in Burkina Faso. The aim was to (i) estimate the level of domestic larval control practices (cleaning of the house and its surroundings, eradication of larval sources, and elimination of hollow objects that might collect water); (ii) identify key determinants; and (iii) explore the structural relationships between these practices, participation in awareness-raising activities and mothers’ knowledge/attitudes/practices, and malaria prevalence among under-five children. Results Overall, 2004 households were surveyed and 1,705 under-five children were examined. Half of the mothers undertook at least one action to control larval proliferation. Mothers who had gone to school had better knowledge about malaria and were more likely to undertake domestic larval control practices. Living in highly exposed rural areas significantly decreased the odds of undertaking larval control actions. Mothers’ participation in malaria information sessions increased the adoption of vector control actions and bednet use. Malaria prevalence was statistically lower among children in households where mothers had undertaken at least one vector control action or used bed-nets. There was a 0.16 standard deviation decrease in malaria prevalence for every standard deviation increase in vector control practices. The effect of bednet use on malaria prevalence was of the same magnitude. Conclusion Cleaning the house and its surroundings, eradicating breeding sites, and eliminating hollow objects that might collect water play a substantial role in preventing malaria among under-five. There is a need for national

    Background This study evaluated the effects on healthcare access inequities of an intervention exempting children under 5 years from user fees in Burkina Faso. Methods The design consisted of two complementary studies. The first was an interrupted time series (56 months before and 12 months after) study of daily curative consultations according to distance (<5, 5–9 and ≥10 km) in a stratified random sample of 18 health centres: 12 with the intervention and 6 without. The second was a household panel survey (n=1214) assessing the evolution of health-seeking behaviours. Multilevel regression was used throughout. Results Attendance doubled under the intervention, after adjusting for Centres de Santé et de Promotion Sociale size, districts, secular trend and seasonal variation. Utilisation increased for all distance ranges and in all of the 12 health centres of the intervention area. The exemption benefited all children (rate ratios (RR)=1.52 (1.23 to 1.88)), whether their health needs were high (RR=1.69 (1.22 to 2.32)) or not (RR=1.46 (1.10 to 1.93)) and whether the children lived near (RR=1.42 (1.09 to 1.85)) or far from a health centre (RR=1.79 (1.31 to 2.43)). The exemption benefited the children of poor families when health need was high and services near (RR=5.23; (1.30 to 20.99)). The amount saved for a child's treatment by the exemption was on average and median 2500 F CFA (≈US$5). Conclusions Exempting children under five from user fees is effective and helps reduce inequities of access. It benefits vulnerable populations, although their service utilisation remains constrained by limitations in geographic accessibility of services. PMID:23776054

    A qualitative study conducted in 2006 shows that many people in Burkina Faso, living with HIV and receiving antiretroviral treatment (ART), have difficulties in meeting the expenses related to care. This anthropological analysis considers their perceptions, the causes and the social impact of these economic problems. This research is based on semi-structured interviews with 35 people living with HIV (PLWHIV) infection, contacted through HIV care programs in Ouagadougou, Bobo-Dioulasso and Ouahigouya. After recording, transcribing and indexing the interviews, we analysed them. Even when they did not have to pay for treatment, most of the subjects faced economic problems dealing with follow-up care and monitoring, transportation, and other expenses, and these problems occur when PLWHIV have already faced the long, complex and expensive therapeutic itinerary before the test that diagnosed HIV infection. The new diet required by the treatment is also mentioned. Moreover, work problems often due to the disease (low output at work, inability to work, job loss) have already decreased patients' income by the time they get treatment. It is not easy for them to return to the level of resources they had before their disease, even if they can find a job. This financial exhaustion frequently leads to the exclusion of PLWHIV from their former solidarity networks, mostly because they can no longer participate in collective contributions or return what they were given when they were totally dependent. The analysis of these conversations shows the relevance of the concept of "social suffering" in describing the social effects of the economic problems that face many PLWHIV on ART, even when treatment is subsidized.

  12. Assessment of providers' referral decisions in Rural Burkina Faso: a retrospective analysis of medical records

    2012-01-01

    Background A well-functioning referral system is fundamental to primary health care delivery. Understanding the providers' referral decision-making process becomes critical. This study's aim was to assess the correctness of diagnoses and appropriateness of the providers' referral decisions from health centers (HCs) to district hospitals (DHs) among patients with severe malaria and pneumonia. Methods A record review of twelve months of consultations was conducted covering eight randomly selected HCs to identify severe malaria (SM) cases among children under five and pneumonia cases among adults. The correctness of the diagnosis and appropriateness of providers' referral decisions were determined using the National Clinical Guidebook as a 'gold standard'. Results Among the 457 SM cases affecting children under five, only 66 cases (14.4%) were correctly diagnosed and of those 66 correctly diagnosed cases, 40 cases (60.6%) received an appropriate referral decision from their providers. Within these 66 correctly diagnosed SM cases, only 60.6% were appropriately referred. Among the adult pneumonia cases, 5.9% (79/1331) of the diagnoses were correctly diagnosed; however, the appropriateness rate of the provider's referral decision was 98.7% (78/79). There was only one case that should not have been referred but was referred. Conclusions The adherence to the National Guidelines among the health center providers when making a diagnosis was low for both severe malaria cases and pneumonia cases. The appropriateness of the referral decisions was particularly poor for children with severe malaria. Health center providers need to be better trained in the diagnostic process and in disease management in order to improve the performance of the referral system in rural Burkina Faso. PMID:22397326

    Poverty at the national and sub-national level is commonly mapped on the basis of household surveys. Typical poverty metrics like the head count index are not able to identify its underlaying factors, particularly in rural economies based on subsistence agriculture. This paper relates agro-ecological marginality identified from regional and global datasets including remote sensing products like the normalized difference vegetation index (NDVI) and rainfall to rural agricultural production and food consumption in Burkina Faso. The objective is to analyze poverty patterns and to generate a fine resolution poverty map at the national scale. We compose a new indicator from a range of welfare indicators quantified from Georeferenced household surveys, indicating a spatially varying set of welfare and poverty states of rural communities. Next, a local spatial regression is used to relate each welfare and poverty state to the agro-ecological marginality. Our results show strong spatial dependency of welfare and poverty states over agro-ecological marginality in heterogeneous regions, indicating that environmental factors affect living conditions in rural communities. The agro-ecological stress and related marginality vary locally between rural communities within each region. About 58% variance in the welfare indicator is explained by the factors of rural agricultural production and 42% is explained by the factor of food consumption. We found that the spatially explicit approach based on multi-temporal remote sensing products effectively summarizes information on poverty and facilitates further interpretation of the newly developed welfare indicator. The proposed method was validated with poverty incidence obtained from national surveys.

    Irrigated agriculture is a significant activity in water stressed semi-arid (e.g., the Sahel) regions, thereby yield and water management are fundamental aspects of irrigation success. Small farmers have often difficulties in managing crops and in evaluating water needs resulting in low yield with excessive water consumption, elevated pumping costs and soil degradation. In different proportions, this overuse of water concerns all irrigation techniques: gravity flows from reservoirs, watering cans irrigation from groundwater wells, micro- or drip irrigation. Baseline requirements for supporting sustainable technology are low costs, easy installation, minimal maintenance, and local production. We present and discuss results from the Info4Dourou2.0 explorative project in Burkina Faso, the main goal of which is to improve small-scale agriculture by the use of sensing and communication technologies. In particular, a support system that couples autonomous and continuous measurements of meteorological variables and soil matrix potential as well as soil humidity with agronomic models has been tested in drip-irrigated fields over a three-year period. In particular, the system is collecting data from three water potential sensors at different locations per field and informs the farmers through a simple interface of the correct amount of water needed by the plant. In its simplicity this system provides an easy to use and install irrigation management setup, and is therefore an ideal candidate in favor of sustainability. Info4Dourou2.0 pilot experiments have shown that farmers can obtain significantly higher yields using lower amounts of water. Overall, this methodology allows facing multiple urgent problems such as the use of environmental data to improve agricultural production towards ecosystem conservation, food security issues and adaptation to climatic change scenarios.

    The interpretation of high-resolution airborne geophysical data integrated with field structural and lithological observations were employed in the creation of a litho-structural framework for the Gaoua region, Burkina Faso. The granite-greenstone domain of Paleoproterozoic age was affected by multiple deformation and mineralization events. The early tectonic phase is characterized by the emplacement of voluminous tholeiitic and calc-alkaline lavas, probably in a volcanic arc setting. The copper mineralization in Gongondy, Dienemera and Mt Biri is concentrated in a diorite/andesite breccia, and is interpreted as porphyry-copper style formed at an early stage of the evolution of the area. Evidence for the first deformation event D1Ga corresponding to N-S shortening was only found in the E-W trending mafic unit bordering the Gaoua batholith to the south. A second deformation phase D2Ga occurred under greenschist facies conditions and lead to a development of more or less penetrative metamorphic foliation and its subsequent folding under overall E-W compression. At later stages, the D2Ga switched to a transcurrent regime characterized by intense N-S to NW-trending steeply dipping shear zones. The first significant gold mineralization event is related to this transcurrent tectonic phase. During subsequent D3Ga, intense network of brittle to brittle-ductile NW and NE faults developed. Economic gold concentrations are attributed to the D3Ga event and are associated with the remobilization of early disseminated low grade gold concentrations. Significant deposits in the area are Nassara, Gomblora, Batié West and Kampti. The last deformation event D4Ga resulted in E-W trending thrust faults and crenulation cleavage planes, under overall N-S compression. No mineralization events related to this stage have been seen.

    One of the most important challenges in addressing global health is for institutions to monitor and use research in policy-making. In low- and middle-income countries (LMICs), civil society organizations such as health professional associations can be key contributors to effective national health systems. However, there is little empirical data on their capacity to use research. This case study was used to gain insight into the factors that affect the knowledge translation performance of health professional associations in LMICs by describing the organizational elements and processes constituting capacity to use research, and examining the potential determinants of this capacity. Case study methodology was chosen for its flexibility to capture the multiple and often tacit processes within organizational routines. The Burkina Faso Public Health Association (ABSP) was studied, using in-depth, semi-structured interviews and key documents review. Five key dimensions that affect the association's capacity to use research to influence health policy emerged: organizational motivation; catalysts; organizational capacity to acquire and organizational capacity to transform research findings; moderating organizational factors. Also examined were the dissemination strategies used by ABSP and its abilities to enhance its capacity through networking, to advocate for more relevant research and to develop its potential role as knowledge broker, as well as limitations due to scarce resources. We conclude that a better understanding of the organizational capacity to use research of health professional associations in LMICs is needed to assess, improve and reinforce such capacity. Increased knowledge translation potential may leverage research resources and promote knowledge-sharing. PMID:21074923

    In this study, the authors investigate farmers' vulnerability to climate variability and evaluate local adoption of technology and farmers' perceptions of adaptation strategies to rainfall variability and policies. A survey was conducted in a community in northern Burkina Faso following the crop failure of 2004. In 2006, following a better harvest, another survey was conducted to compare farmers' actions and reactions during two contrasted rainy seasons. The results confirm that farmers from this community have substantially changed their practices during the last few decades. They have adopted a wide range of techniques that are intended to simultaneously increase crop yield and reduce yield variability. Micro water harvesting (Zaï) techniques have been widely adopted (41%), and a majority of fields have been improved with stone lines (60%). Hay (48%) and sorghum residues are increasingly stored to feed animals during the dry season, making bull and sheep fattening now a common practice. Dry season vegetable production also involves a majority of the population (60%). According to farmers, most of the new techniques have been adopted because of growing land scarcity and new market opportunities, rather than because of climate variability. Population pressure has reached a critical threshold, while land scarcity, declining soil fertility and reduced animal mobility have pushed farmers to intensify agricultural production. These techniques reduce farmers' dependency on rainfall but are still insufficient to reduce poverty and vulnerability. Thirty-nine percent of the population remains vulnerable after a good rainy season. Despite farmers' desire to remain in their own communities, migrations are likely to remain a major source of regular income and form of recourse in the event of droughts.

    Pedicure-manicure represents the aesthetic care of hands, feet and nails. In Burkina Faso, the use of manicure-pedicure products, the techniques used and the level of risk remain unknown. The aim of our study was to evaluate the practice of manicure-pedicure in the city of Ouagadougou. We conducted a descriptive cross-sectional study of all practitioners with at least six months experience in aesthetic care and customers present at the time of the survey from December 2010 to November 2012. We interviewed a total of 313 practitioners and 313 clients. The average age of practitioners was 19 years and of customers was 32.2 years. Fixed location practitioners were mostly women (96.87%) while mobile practitioners were mostly men (68.37%); 64.53% of customers were women. The percentage of practitioners who did not receive professional training was 93.92%. 29.7% of practitioners soaked the instruments in javel water for at least ten minutes; 75.71% knew that the use of certain tools was dangerous and 26.51% had side effects. 40.25% of customers knew that the used equipment may pose some risks and 30.35% were victims of accidents. The manicure and pedicure is done in hair salons by untrained hairdressers to the professional practice. The origin and composition of the products is not known. Not recommended products are used (foot soak shampoo, razor blade and scissors for feet scraping). The use of manicure and/or pedicure is sometimes necessary but that should not obscure the risks to which it exposes customers. Customers education and practitioners training seem necessary to minimize risks. PMID:27642448

    We study the spatial geography of schistosomiasis in the african context of Burkina Faso by means of a spatially explicit model of disease dynamics and spread. The relevance of our work lies in its ability to describe quantitatively a geographic stratification of the disease burden capable of reproducing important spatial differences, and drivers/controls of disease spread. Among the latters, we consider specifically the development and management of water resources which have been singled out empirically as an important risk factor for schistosomiasis. The model includes remotely acquired and objectively manipulated information on the distributions of population, infrastructure, elevation and climatic drivers. It also includes a general description of human mobility and addresses a first-order characterization of the ecology of the intermediate host of the parasite causing the disease based on maximum entropy learning of relevant environmenal covariates. Spatial patterns of the disease were analyzed about their disease-free equilibrium by proper extraction and mapping of suitable eigenvectors of the Jacobian matrix subsuming all stability properties of the system. Human mobility was found to be a primary control of both pathogen invasion success and of the overall distribution of disease burden. The effects of water resources development were studied by accounting for the (prior and posterior) average distances of human settlements from water bodies that may serve as suitable habitats to the intermediate host of the parasite. Water developments, in combination with human mobility, were quantitatively related to disease spread into regions previously nearly disease-free and to large-scale empirical incidence patterns. We concluded that while the model still needs refinements based on field and epidemiological evidence, the framework proposed provides a powerful tool for large-scale, long-term public health planning and management of schistosomiasis.

    Food insecurity is affecting an increasing number of urban poor in the developing world. Yet seasonal characteristics of food intakes have rarely been studied in West African cities. The objective of the present study was to assess the seasonality of the dietary dimension of household food security in Ouagadougou (Burkina Faso). In 2007, two sets of data were collected during the lean and post-harvest seasons, respectively, on a representative sample of 1056 households. At each season, two non-consecutive 24 h recalls were performed at the household level. Food prices were also recorded. Household food security was assessed by the household's mean adequacy ratio (MAR) for energy and eleven micronutrients. Changes in the MAR according to the season were analysed by mixed multivariate linear regression. Results showed that intakes of energy and of ten micronutrients were significantly lower during the lean season than during the post-harvest season, leading to a lower MAR in the lean season (49·61 v. 53·57, P < 0·0001). This was related to less frequent consumption and consumption of smaller amounts of vegetables and of foods prepared at home. Food security relied heavily on food expenses (P < 0·0001) and on the price of meat/fish (P = 0·026). Households with economically dependent adults (P = 0·021) and larger households (P < 0·0001) were the most vulnerable, whereas education (P = 0·030), social network (P = 0·054) and urban origin other than Ouagadougou (P = 0·040) played a positive role in food security. To achieve food security in Ouagadougou, access to micronutrient-dense foods needs to be ensured in all seasons.

  2. Prevalence and characterization of Salmonella enterica from the feces of cattle, poultry, swine and hedgehogs in Burkina Faso and their comparison to human Salmonella isolates

    2013-01-01

    Background Production and wild animals are major sources of human salmonellosis and animals raised for food also play an important role in transmission of antimicrobial resistant Salmonella strains to humans. Furthermore, in sub-Saharan Africa non-typhoidal Salmonella serotypes are common bloodstream isolates in febrile patients. Yet, little is known about the environmental reservoirs and predominant modes of transmission of these pathogens. The purpose of this study was to discover potential sources and distribution vehicles of Salmonella by isolating strains from apparently healthy slaughtered food animals and wild hedgehogs and by determining the genetic relatedness between the strains and human isolates. For this purpose, 729 feces samples from apparently healthy slaughtered cattle (n = 304), poultry (n = 350), swine (n = 50) and hedgehogs (n = 25) were examined for the presence of Salmonella enterica in Burkina Faso. The isolates were characterized by serotyping, antimicrobial-susceptibility testing, phage typing, and pulsed-field gel electrophoresis (PFGE) with XbaI and BlnI restriction enzymes. Results Of the 729 feces samples, 383 (53%) contained Salmonella, representing a total of 81 different serotypes. Salmonella was present in 52% of the cattle, 55% of the poultry, 16% of the swine and 96% of the hedgehog feces samples. Antimicrobial resistance was detected in 14% of the isolates. S. Typhimurium isolates from poultry and humans (obtained from a previous study) were multiresistant to the same antimicrobials (ampicillin, chloramphenicol, streptomycin, sulfonamides and trimethoprim), had the same phage type DT 56 and were closely related in PFGE. S. Muenster isolates from hedgehogs had similar PFGE patterns as the domestic animals. Conclusions Based on our results it seems that production and wild animals can share the same Salmonella serotypes and potentially transmit some of them to humans. As the humans and animals often live in close

    A 35-month cluster randomized controlled trial was conducted in Burkina Faso to test whether a radio campaign focused on child health, broadcast between March 2012 and January 2015, could reduce under-5 mortality. This paper describes the design and implementation of the mass media intervention in detail, including the Saturation+ principles that underpinned the approach, the creative process, the lessons learned, and recommendations for implementing this intervention at scale. The Saturation+ approach focuses on the 3 core principles of saturation (ensuring high exposure to campaign messages), science (basing campaign design on data and modeling), and stories (focusing the dramatic climax on the target behavior) to maximize the impact of behavior change campaigns. In Burkina Faso, creative partnerships with local radio stations helped us obtain free airtime in exchange for training and investing in alternative energy supplies to solve frequent energy problems faced by the stations. The campaign used both short spots and longer drama formats, but we consider the short spots as a higher priority to retain during scale-up, as they are more cost-effective than longer formats and have the potential to ensure higher exposure of the population to the messages. The implementation research synthesized in this paper is designed to enable the effective adoption and integration of evidence-based behavior change communication interventions into health care policy and practice.

    The flea beetle Aphthona whitfieldi Bryant (Coleoptera: Chrysomelidae) is the main pest of the bioenergy crop Jatropha curcas L. (Euphorbiaceae) in Burkina Faso and several other West African countries. Adults severely defoliate plants, resulting in seedling mortality, poor growth, and low yields. To study the population dynamics of the pest in the Sissili Province of Burkina Faso, 12 sites were monitored weekly during a year and 31 sites were inspected for damage at the peak period of insect abundance. The effect of cropping systems (hedge, intercropping, and monoculture) and surrounding vegetation on population densities of A. whitfieldi was assessed. Beetles were rarely found in the dry season and peaked in the second half of the rainy season. The cropping system did not significantly influence the abundance and attack level. In contrast, the close vicinity of fallow lands seems to increase damage levels. Many aspects of the biology and ecology of A. whitfieldi remain to be investigated before sustainable control methods can be developed. However, this study already allows us to propose recommendations for further research on management. PMID:26206896

    We conducted a prospective evaluation of the “Rapid Scale-Up” (RSU) program in Burkina Faso, focusing on the integrated community case management (iCCM) component of the program. We used a quasi-experimental design in which nine RSU districts were compared with seven districts without the program. The evaluation included documentation of program implementation, assessments of implementation and quality of care, baseline and endline coverage surveys, and estimation of mortality changes using the Lives Saved Tool. Although the program trained large numbers of community health workers, there were implementation shortcomings related to training, supervision, and drug stockouts. The quality of care provided to sick children was poor, and utilization of community health workers was low. Changes in intervention coverage were comparable in RSU and comparison areas. Estimated under-five mortality declined by 6.2% (from 110 to 103 deaths per 1,000 live births) in the RSU area and 4.2% (from 114 to 109 per 1,000 live births) in the comparison area. The RSU did not result in coverage increases or mortality reductions in Burkina Faso, but we cannot draw conclusions about the effectiveness of the iCCM strategy, given implementation shortcomings. The evaluation results highlight the need for greater attention to implementation of iCCM programs. PMID:26787147

    In Burkina Faso, abortion is legally restricted and socially stigmatised, but also frequent. Unsafe abortions represent a significant public health challenge, contributing to the country's very high maternal mortality ratio. Inspired by an internationally disseminated public health framing of unsafe abortion, the country's main policy response has been to provide post-abortion care (PAC) to avert deaths from abortion complications. Drawing on ethnographic research, this article describes how Burkina Faso's PAC policy emerged at the interface of political and moral negotiations between public health professionals, national bureaucrats and international agencies and NGOs. Burkinabè decision-makers and doctors, who are often hostile to induced abortion, have been convinced that PAC is ‘life-saving care’ which should be delivered for ethical medical reasons. Moreover, by supporting PAC they not only demonstrate compliance with international standards but also, importantly, do not have to contend with any change in abortion legislation, which they oppose. Rights-based international NGOs, in turn, tactically focus on PAC as a ‘first step’ towards their broader institutional objective to secure safe abortion and abortion rights. Such negotiations between national and international actors result in widespread support for PAC but stifled debate about further legalisation of abortion. PMID:25132157

    In South-West of Burkina Faso, palm wine is produced by spontaneous fermentation of the sap from a specific palm tree Borassus akeassii and plays an important role in people's lives. Saccharomyces cerevisiae is the main agent of this alcoholic fermentation but little is known about the diversity of the isolates from palm. In this work, 39 Saccharomyces cerevisiae strains were isolated from palm wine samples collected from 14 sites in Burkina Faso, as well as 7 isolates obtained from sorghum beer (Dolo) from 3 distant sites. Their diversity was analyzed at 12 microsatellite loci, and compared to the genotypes obtained for other African yeast populations isolated from Cocoa hulks from Ghana, sorghum beer from Ivory Coast, palm wine from Djibouti Republic, and to our database of strains from miscellaneous origins (bread, beer, wine, sake, oaks…). The ploidy of these strains has been assessed as well by flow cytometry. Our results show that B. akeassii palm wine contains a specific yeast population of diploid strains, different from Dolo produced in the same area and from other palm wine strains from Ivory Coast, Nigeria, or Djibouti Republic. In contrast, Dolo strains appeared as a group of related and mainly tetraploid strains despite being isolated from different countries. PMID:26202324

  12. Differences in timing of mating swarms in sympatric populations of Anopheles coluzzii and Anopheles gambiae s.s. (formerly An. gambiae M and S molecular forms) in Burkina Faso, West Africa

    PubMed Central

    2013-01-01

    Background The M and S molecular forms of Anopheles gambiae s.s. Giles appear to have speciated in West Africa and the M form is now formally named An. coluzzii Coetzee & Wilkerson sp.n. and the S form retains the nominotypical name (abbreviated here to An. gambiae). Reproductive isolation is thought to be the main barrier to hybridisation; even though both species are found in the same mating swarms, hybrid fertilisations in copulae have not been found in the study area. The aim of the study, therefore, was to determine whether differences in circadian and/or environmental control over the timing of swarming in the two species contribute to reproductive isolation. Methods The timing of male swarming in these species was recorded four nights per month over four years at five swarming sites in each of two villages. The timing of the start and end of swarming, and the concurrent environmental parameters, temperature, humidity and light intensity, were recorded for n = 20 swarms/month/species. The timing of 'spontaneous’ activity at dusk of individual An. coluzzii and An. gambiae males was video-recorded in an actograph outdoors for 21 nights. Results Of the environmental parameters considered, swarming was most strongly correlated with sunset (r2 > 0.946). Anopheles gambiae started and stopped swarming earlier than An. coluzzii (3:35 ± 0:68 min:sec and 4:51 ± 1:21, respectively), and the mean duration of swarming was 23:37 ± 0:33 for An. gambiae and 21:39 ± 0:33 for An. coluzzii. Accordingly, in principle, whenever both species swarm over the same marker, a mean of 15.3 ± 3.1% of An. gambiae swarming would occur before An. coluzzii males arrived, and 19.5 ± 4.55% of An. coluzzii swarming would occurred after An. gambiae males had stopped swarming. These results are consistent with the finding that An. gambiae males became active in the actograph 09:35 ± 00:22 min:sec earlier than An. coluzzii males. Conclusions The

    Tree crown cover (CC) is an important vegetation attribute for land cover characterization, and for mapping and monitoring forest cover. Free data from Landsat and Sentinel-2 allow construction of fine resolution satellite image time series and extraction of seasonal features for predicting vegetation attributes. In the savannas, surface reflectance vary distinctively according to the rainy and dry seasons, and seasonal features are useful information for CC mapping. However, it is unclear if it is better to use spectral bands or vegetation indices (VI) for computation of seasonal features, and how feasible different VI are for CC prediction in the savanna woodlands and agroforestry parklands of West Africa. In this study, the objective was to compare seasonal features based on spectral bands and VI for CC mapping in southern Burkina Faso. A total of 35 Landsat images from November 2013 to October 2014 were processed. Seasonal features were computed using a harmonic model with three parameters (mean, amplitude and phase), and spectral bands, normalized difference vegetation index (NDVI), green normalized difference vegetation index (GNDVI), normalized difference water index (NDWI), tasseled cap (TC) indices (brightness, greenness, wetness) as input data. The seasonal features were employed to predict field estimated CC (n = 160) using Random Forest algorithm. The most accurate results were achieved when using seasonal features based on TC indices (R2: 0.65; RMSE: 10.7%) and spectral bands (R2: 0.64; RMSE: 10.8%). GNDVI performed better than NDVI or NDWI, and NDWI resulted in the poorest results (R2: 0.56; RMSE: 11.9%). The results indicate that spectral features should be carefully selected for CC prediction as shown by relatively poor performance of commonly used NDVI. The seasonal features based on three TC indices and all the spectral bands provided superior accuracy in comparison to single VI. The method presented in this study provides a feasible method to map

    The conversion of natural ecosystems into agricultural land affects the atmospheric CO2 concentration whose increase contributes to global warming. In the low activity clay soils (LAC) of the tropics, farming is largely dependent on the level of soil organic carbon (SOC) for sustainable crop production. In this study, we investigated the changes in SOC in Plinthosols along a cultivation chronosequence in the Dano district (Southwest Burkina-Faso). The chronosequence consisted of undisturbed savannah (Y0) and 11 agricultural fields with short and long histories of cultivation ranging from 1-year-old cropland to 29-year-old cropland (Y29). About 14 soil profiles were described and soil composite samples were taken per horizon. Particulate organic matter (POM) was fractionated according to particle size: fraction 2000 - 250 μm (POM1), 250 μm - 53 μm (POM2), 53 μm - 20 μm (POM3), and < 20 μm (nonPOM). Our results revealed that the extent of change in SOC stock varied with depth and the age of the cropland. The impact of cultivation was greater in the top 10 cm with a decrease in SOC stock of 21 t C/ha after 29 years of cropping indicating that about 60% of the initial stock in the native vegetation had been released. The SOC content and stock in the different POM fractions followed the following pattern: non POM > POM1 > POM3 > POM2 carbon no matter the duration of land use. However, SOC losses occurred not only in the labile C pools but also in the stabile nonPOM fraction with increasing duration of agricultural land use. Compared to the initial carbon content in the Y0 field, about 59% of carbon content loss occurred in the POM1 (> 250 μm), 53% in the POM2 (250 - 53 μm), 52 % in the POM3 (53 - 20 μm) and 47% in the nonPOM fraction (< 20 μm) after 11 years of cultivation while 79 % occurred in the POM1 C, 75% in the POM2C, 78 % in the POM3 C and 67% in the nonPOM C after 29 years of cultivation. Though most carbon was found as nonPOM, indicating that organo

    Background Despite low endemicity, malaria remains a major health problem in urban areas where a high proportion of fevers are presumptively treated using anti-malarial drugs. Low acquired malaria immunity, behaviour of city-dwellers, access to health care and preventive interventions, and heterogenic suitability of urban ecosystems for malaria transmission contribute to the complexity of the malaria epidemiology in urban areas. Methods The study was designed to identify the determinants of malaria transmission estimated by the prevalence of anti-circumsporozoite (CSP) antibodies, the prevalence and density of Plasmodium falciparum infection, and the prevalence of malarial disease in areas of Ouagadougou, Burkina-Faso. Thick blood smears, dried blood spots and clinical status have been collected from 3,354 randomly chosen children aged 6 months to 12 years using two cross-sectional surveys (during the dry and rainy seasons) in eight areas from four ecological strata defined according to building density and land tenure (regular versus irregular). Demographic characteristics, socio-economic information, and sanitary and environmental data concerning the children or their households were simultaneously collected. Dependent variables were analysed using mixed multivariable models with random effects, taking into account the clustering of participants within compounds and areas. Results Overall prevalences of CSP-antibodies and P. falciparum infections were 7.7% and 16.6% during the dry season, and 12.4% and 26.1% during the rainy season, respectively, with significant differences according to ecological strata. Malaria risk was significantly higher among children who i) lived in households with lower economic or education levels, iii) near the hydrographic network, iv) in sparsely built-up areas, v) in irregularly built areas, vi) who did not use a bed net, vii) were sampled during the rainy season or ii) had traveled outside of Ouagadougou.

    Policy entrepreneurs are individuals who attempt to influence the policy process and its outcomes through their opportunistic or incremental actions. Their success in the policy-making process has been associated with the convergence of four factors: behavioural traits; institutional factors; network position and political capital. Policy entrepreneurs have received little study in low- and middle-income country policy research despite observations of individualized decision-making, informal institutions and the unequal distribution and exercise of power in policymaking. This article aims to identify whether policy entrepreneurs were present in the policy process around integrated community case management (iCCM) in Burkina Faso, whether they were successful in achieving policy change, and whether success or failure can be explained using existing policy entrepreneur frameworks from high-income polities. This mixed methods policy study collected data from in-depth qualitative interviews and social network surveys of actors involved in iCCM policymaking [known locally as C-integrated management of childhood illness (IMCI)]; data were analysed based on the framework categories. Interview data pointed to one key individual who played a significant role in the inclusion of pneumonia treatment into the country’s iCCM policy, an issue that had been a point of contention between government policy elites and development partners. Social network data confirmed that this actor was strategically located in the policy network to be able to reach the most other actors and to be able to control the flow of information. Although some development partner actors were as strategically located, none had the same level of authority or trust as was imbued by being a member of the government civil service. The entrepreneur’s mid-level rank in the health ministry may have encouraged him/her to invest political capital and take risks that would not have been feasible or attractive to

    Progress towards reducing mortality and malnutrition among children < 5 years of age has been less than needed to achieve related Millennium Development Goals. Therefore, several international agencies joined to 'Reposition children's right to adequate nutrition in the Sahel', starting with an analysis of current activities related to infant and young child nutrition (IYCN). The objectives of the present paper are to compare relevant national policies, training materials, programmes, and monitoring and evaluation activities with internationally accepted IYCN recommendations. These findings are available to assist countries in identifying inconsistencies and filling gaps in current programming. Between August and November 2008, key informants responsible for conducting IYCN-related activities in Burkina Faso were interviewed, and 153 documents were examined on the following themes: optimal breastfeeding and complementary feeding practices, prevention of micronutrient deficiencies, screening and treatment of acute malnutrition, prevention of mother-to-child transmission of HIV, food security and hygienic practices. National policy documents addressed nearly all of the key IYCN topics, specifically or generally. Formative research has identified some local barriers and beliefs related to general breastfeeding and complementary feeding practices, and other formative research addressed about half of the IYCN topics included in this review. However, there was little evidence that this formative research was being utilized in developing training materials and designing programme interventions. Nevertheless, the training materials that were reviewed do provide specific guidance for nearly all of the key IYCN topics. Although many of the IYCN programmes are intended for national coverage, we could only confirm with available reports that programme coverage extended to certain regions. Some programme monitoring and evaluation were conducted, but few of these provided

    Assessing landscape and population's dynamics at watershed level contribute to address anthropogenic aspect of climate change issue owing to the close link between LULC and climate changes. The objective of this study is to explore the dependencies of population to land management changes in Massili basin (2612 km²) located in central Burkina Faso. A set of three satellite scenes was acquired for the years 1990 (Landsat 7 ETM), 2002 (Landsat 7 ETM+) and 2013 (Landsat 8 OLI/TIRS) from the Global Land Cover Facility's (GLCF) website. Census data were provided by the National institute of statistics and demographic (INSD). The satellites images were classified using object-oriented classification method which was supported by historic maps and field data. Those were collected in order to allow for class definition, verification and accuracy assessments. Based on the developed land use maps, change analysis was carried out using post classification comparison in GIS. Finally, derived land use changes were compared with census data in order to explore links between population dynamics and the land use changes. It was found in 1990 that Massili watershed LULC was dominated by Tree/shrub savannah (69%, 1802.28 km2 ), Farm/Fallow was representing 22%, Gallery forest (4%), Settlement (3%), Barre soil (1%), Water bodies (1%). In 2002, the major landscape was Farm (54%). Tree/Shrub savannas were reduced to 36% while the Gallery Forest was decreased to1% of the basin area. The situation has also slightly changed in 2013 with an increase of the area devoted to farm/fallow and settlement at a rate of 3% and Gallery forest has increased to 4%. The changes in land use are in agreement with a notable increase in population. The analysis of census data showed that the number of inhabitants increased from 338 inhabitants per km2 in 1990 to 1150 inhabitants per km2 in 2013. As shown by statistical analysis (Kendall correlation tau=0.9), there is a close relation between both dynamics.

    In the Sourou area of Burkina Faso, parasitological and malacological surveys of urinary schistosomiasis have been carried out in the constructed sites of Guédougou, Niasan and Débé dating respectively from 1967, 1986 and 1996. The investigations covered also the traditional villages of Lanfiera, Di, Poro, Tiao and Mara situated in the middle of the hydroagricultural planning for the first, very close to the lake for the second and about twenty kilometres distant for the three last. These towns represent the main sites in the Sourou area. The results of the parasitological surveys showed that urinary schistosomiasis was present in all sites. The levels of prevalence varied considerably: 70.3% in Guiédougou, 40.8% in Niassan, 8.5% in Débè in the irrigated zone, 55.6% in Lanfiéra, 56.8% in Di, 13.2% in Poro, 83.3% in Tiao and 64.7% in Mara. Concerning the malacological investigation, two species (Bulinus senegalensis and B. truncatus) were shown to be intermediate hosts of Schistosoma haematobium. The first was endemic to the area while the second was compatible with S. haematobium from the Sourou and other zones. Compared to the results of earlier investigations, the endemic had worsened with differences according to sites. This disparity of prevalence levels which has already been observed in other hydroagricultural area results from many factors, among which the impact of irrigation activities, the aquatic biotope system (irrigation canals, natural lake, pools and temporary rivers) and the type of contact of human communities with water rank high. Schistosomiasis expansion is amplified by the intermediate host dynamics and the introduction of new schistosomes carried by the new workers arriving from all over the country. In these conditions, in order to reduce rapidly prevalence levels, preventive measures should be centred on chemotherapy for the population. The treatment should be administered during a period of weak intermediate host density and be

    Despite the formulation of the Bamako initiative in 1992 in Burkina Faso, not until 2001 and the launching of a project by a nongovernmental organization was the policy really implemented in a region of the country. One of the goals of this policy is to improve access to health care by using generic essential drugs. The objective of this article is to summarize the results of the evaluation of the project's ability to improve the population's access to drugs. The project lasted three years (2001-2003) and the interventions took place in 41 basic health centres of three districts. According to WHO, improving access to drugs requires consideration of four essential factors: rational use, affordable prices, financial viability, and effectiveness of the distribution. The average number of drugs prescribed per prescription sheet (n = 1061) was 2.4; 93% of the drugs were prescribed by their generic name (international non-proprietary names); 44% of infant diarrheas were treated with oral rehydration salt. National drug prices were respected but not the directives aiming at exempting from payment or subsidizing certain population sub-groups (children, indigents). The average annual cash flow of the basic health centres was 1.2 million F CFA and it increased by 854% compared to the beginning of the project. The cost-recovery scheme for administrative expenses was 106%. The average annual availability of the 10 essential drugs was 89%. Utilization rates increased (0.13 in 1999 to 0.21 in 2003) but not significantly differently than in other basic health centres of the area not supported by the project (p = 0.084). The project succeeded in improving access to these drugs for the overall population but not for the worst-off. The drugs are now geographically available for all and financially accessible for those who can afford to pay. The intervention strategy supported the sustainability of the project's activities but much remains to be done to provide the poorest with

    In many developing countries a long time series of solar radiation measurements are not often available. This is due to the cost, maintenance and calibration requirements of measuring devices. Consequently, the use of solar energy by Photovoltaic (PV) conversion copes with the choice and the optimization of the PV system. This work concerned the analysis of climate parameters strongly influencing the Photovoltaic (PV) systems energy production and the simulation of an ideal system based on a single PV module. Estimation and analysis of time series of climate parameters covered a set of six weather stations with respect to the three climatic zones in Burkina Faso (BF), over 38 years. The analysis showed that the solar irradiation in BF lies between 3 kWh/m2/day and 7.5 kWh/m2/day. The highest values of the solar irradiation are measured in the Northern part of the country while lowest values are measured in the Southern part. Daily mean temperature for all weather stations was greater than the Standard Test Condition (STC) temperature (25°C) over a long period of the year. Information on solar irradiation and temperature is fundamental for PV systems sizing process. For PV performance evaluation, a simulation is carried out using an ideal system composed of a single PV module from TENESOL Company. This simulation is performed for three classes of climatic conditions "Mean situation", "Adverse situation", and "Beneficial situation", and evaluated for six sitesacross BF. The results revealed intra-annual and spatial variability of Maximum Power (MP). Across BF, MP varied between 60 W/day and 190 W/day in Sahelian zone, between 65 W/day and 185 W/day in soudano-sahelian zone, and between 67 W/day and 208 W/day in Soudanian zone. MP intra-annual variability is higher during the period July-August, mainly for "Beneficial situation". The negative effect of temperature on PV energy production is specially amplified in Sahelian zone due to its highest temperatures. This

Elle repond a la question fondamentale de l'interpretation des effets des facteurs climatiques et socioeconomiques sur le milieu pastoral. La recherche s'est appuyee sur plusieurs hypotheses de travail: possibilite d'utilisation de modele de simulation, d'approche multicritere et de donnees de teledetection dans un cadre de systeme d'information geographique. L'evolution spatiotemporelle des parametres de productivite du milieu a ete evaluee par approche dynamique selon le modele de Wu et al. (1996) qui modelise les interactions entre le climat, le milieu physique, le vegetal et l'animal pour mieux quantifier la biomasse primaire. A ce modele, quatre parametres ont ete integres par approche floue et multicritere afin de prendre en compte la dimension socioeconomique de la productivite pastorale (apport majeur de la recherche): la sante, l'education, l'agriculture et l'eau. La teledetection (imagerie SPOT) a permis de definir la production primaire a partir de laquelle les simulations ont ete realisees sur 10 annees. Les resultats obtenus montrent une bonne correlation entre biomasse primaire in situ et celle calculee pour les deux modeles, avec toutefois une meilleure efficacite du modele modifie (4 fois plus) dans les zones de forte productivite ou l'on note un taux de surexploitation agricole eleve. A cause de la variabilite spatiale de la production primaire in situ, les erreurs des resultats de simulation (8 a 11%) sont acceptables et montrent la pertinence de l'approche grace a l'utilisation des SIG pour la spatialisation et l'integration des differents parametres des modeles.

    Résumé Introduction l’impact négatif de la stigmatisation sur la prévention du VIH et la prise en charge a été documenté. La stigmatisation a été analysée au plan qualitatif au Burkina Faso, où la prévalence VIH est faible (1 %). Des mesures quantitatives sont encore nécessaires pour identifier les formes et manifestations majeures de la stigmatisation. Méthodologie dans le cadre de l’étude MATCH (Multi-country African Study on Testing and Counselling for HIV), une étude transversale a été conduite auprès de personnes ayant déjà fait le test VIH. Les personnes séropositives ont été interrogées sur les conséquences du résultat VIH+. Leur vécu de la stigmatisation a été évalué à travers 20 indicateurs de manifestations de la stigmatisation, regroupés en trois formes de stigmatisation/discrimination. Résultats au total 219 PVVIH ont été recrutées. L’autostigmatisation est la forme majeure de stigmatisation. Elle est estimée dans cette étude à 46 % comparativement à la stigmatisation dans les relations interpersonnelles évaluée à 40 % et la stigmatisation dans les services de santé qui est de 11 %. L’expérience de la stigmatisation dans les relations interpersonnelles est davantage rapportée par les PVVIH qui ont partagé leur résultat, celles qui ont un faible niveau de scolarisation, les veufs/veuves ou séparés, et les membres d’association. La stigmatisation dans les services de santé est rapportée plus souvent par les membres d’associations. Conclusion les programmes de prise en charge doivent, parallèlement à l’extension des antirétroviraux, intégrer un volet psychologique plus adapté aux besoins. Les activités d’appui psychosocial ciblant davantage l’individu doivent être développées, surtout au sein des associations. PMID:25291886

    Background Food-based approaches such as biofortification are meant to sustainably address micronutrient deficiencies in poor settings. Knowing more about micronutrient intakes and deficiencies is a prerequisite to designing and evaluating interventions. Objective The objectives of the study were to assess biological status and dietary intakes of iron, zinc and vitamin A among women and children aged 36–59 months in rural Burkina Faso and to study relationships between intake and status to better inform future food-based interventions. Design A cross-sectional survey was carried out in two rural provinces of Burkina Faso on a random cluster sample of 480 mother-child pairs. Dietary data was obtained by 24-hour recalls repeated on a random sub-selection of 37.5% of subjects to allow calculation of nutrient’s probability of adequacy (PA). Biomarkers were measured on a sub-sample of 180 mother-child pairs. Blood samples were analyzed for hemoglobin, serum ferritin, soluble transferrin receptors (sTfR), C-reactive protein, alpha-1-glycoprotein, serum zinc concentration (SZnC) and retinol. For each micronutrient the relationship between biomarker and dietary intake was investigated by multiple linear regression models accounting for inflammatory biomarkers. Results Mean PA for iron, zinc and vitamin A was 0.49, 0.87 and 0.21 among women and 0.61, 0.95 and 0.33 among children, respectively. Prevalence of anemia, corrected low serum ferritin and high sTfR was 37.6%, 4.0% and 77.5% among women and 72.1%, 1.5% and 87.6% among children, respectively. Prevalence of low SZnC and corrected low serum retinol was 39.4% and 12.0% among women and 63.7% and 24.8% among children, respectively. There was a tendency for a positive relationship between vitamin A intakes and serum retinol among women (β = 0.0003, P = 0.06). Otherwise, no link was found between micronutrients biomarkers and intakes. Conclusion Our study depicted different images of micronutrient deficiencies when

    Background National surveys in low-income countries increasingly rely on self-reported measures of health. The ease, speed, and economy of collecting self-reports of health make such collection attractive for rapid appraisals. However, the interpretation of these measures is complicated since different cultures understand and respond to the same question in different ways. Objective The aim of this pilot study was to develop a culturally sensitive tool to study the self-reported health (SRH) of the local adult population in Burkina Faso. Design The study was carried out in the 2009 rainy season. The sample included 27 men and 25 women aged 18 or older who live in semi-urban Nouna, Burkina Faso. Three culturally adapted instruments were tested: a SRH question, a wooden visual analogue scale (VAS), and a drawn VAS. Respondents were asked to explain their answers to each instrument. The narratives were analyzed with the content analysis technique, and the prevalence of poor SRH was estimated from the quantitative data by stratification for respondent background variables (sex, age, literacy, education, marital status, ethnicity, chronic diseases). The correlation between the instruments was tested with Spearman’s correlation test. Results The SRH question showed a 38.5% prevalence of poor SRH and 44.2% prevalence with both VAS. The correlation between the VAS was 0.89, whereas the correlation between the VAS and the SRH question was 0.60–0.64. Nevertheless, the question used as the basis of each instrument was culturally sensitive and clear to all respondents. Analysis of the narratives shows that respondents clearly differentiated between the various health statuses. Conclusion In this pilot, we developed and tested a new version of the SRH question that may be more culturally sensitive than its non-adapted equivalents. Additional insight into this population’s understanding and reporting of health was also obtained. A larger sample is needed to further study

  7. Seasonal And Intra-seasonal Hydrological Responses To Change In Climate Pattern And Small Dams of the Faga Watershed In Burkina-Faso

    In response to the increasing demand for food linked to the substantial growth of population in Burkina Faso, irrigation has been widely used by the farming community to support agricultural production. Thus a promising option for water resources development in such a context is to increase the number of small dams. It is assumed that the great number of small dams may have effect on sub-basins' hydrological dynamic. This study aims to assess the seasonal and the intra-seasonal change in river basins hydrology with the case study of the Faga River sub-basin located in Burkina-Faso, West Africa, using Water Simulation Model (WaSiM). For this watershed the number of small dams is slightly very important (More than 60) and their impact on the watershed runoff has been estimated simultaneously with the change in climate pattern. The coefficient of variation for rainfall in this sub-basin from 1982 to 2010 is 0.097 and the stream flow presents a seasonal average of 25.58Km3 per month for the same period. The intra-seasonal climate variation for the same period is estimated at 0.087 in the scenario where any dam has not been considered. Results based on simulation including the five important dams over the sub-basin show that the overall effect of small dams is on average a 20.76% in runoff. Projections using the Representative Concentration Pathways (RCP) 4.5 and 8.5 climate scenarios with increase of 25% of dams' number show a probable decrease of about 29.54% and 35.25% of the average during the next fifty years runoff. The study findings show that small dams reduce significantly the runoff from their watershed and the uncertainties related to the sustainability of the resource seems to be increasing during the same period. Therefore, despite the very large number of water storage infrastructures, reservoirs operating strategies have to be achieved for water sustainability within the Faga sub-basin.

    Four insecticides (acetamiprid, cypermethrin, endosulfan and profenofos) are used quarterly in the cotton-growing areas of Burkina Faso, West Africa. These insecticides were investigated in soils collected from traditionally cultivated and new cotton areas. Also, the effects of insecticide exposure on the developmental instability of honey bees, Apis mellifera, were explored. In soil samples collected three months after insecticide treatments, endosulfan and profenofos concentrations varied in the range of 10-30 μg kg(-1) in the traditionally cultivated zones and 10-80 μg kg(-1) in the new cotton zones, indicating a pollution of agricultural lands. However, only profenofos concentrations were significantly higher in the new cotton zone than the traditionally cultivated zones. In addition, the index of fluctuating asymmetry, FA1, in the length of second tarsus (L(HW)) was increased for bees when exposed to pesticide treated cotton fields for 82d, and their FA levels were significantly higher than those in the control colony in an orchard. The other studied traits of bees exposed to insecticides were not significantly different from controls. Our results indicate that FA may be considered as a biomarker reflecting the stress induced by insecticide treatments. However, the relationship between FA and stressors needs further investigations.

    Riverine tsetse (Glossina) as Glossina palpalis gambiensis Vanderplank 1949 and Glossina tachinoides Westwood 1850 are the main vectors for African animal trypanosomoses in Burkina Faso. Vector control has been proven efficient in disease containment, but its success is endangered by the reinvasion of tsetse from neighbouring areas. Thus, identifying relic populations can enhance the success rate of vector control efforts. This is currently carried out through microsatellite analysis which is time-consuming and costly. Recently, matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry-based analysis has become a routine method in microbial species identification. Owing to the rapidness and cost-effectiveness, this approach has been extended towards species identification of higher organisms such as tsetse. Following the recent experiences in distinguishing two genotypes of Prototheca spp., it is of interest to explore the validity of mass spectrometry for tsetse population differentiation. As a preliminary test, we submitted male and female G. palpalis gambiensis and G. tachinoides from Sideradougou and Folonzo, Burkina Faso (distance 60 km) to matrix-assisted laser desorption/ionisation analysis. The wing samples were utilized for protein extraction and mass spectra in a broad mass to charge ratio (2,000-20,000 kDa) were obtained. Specific peaks appeared to represent species, sex and location. Then, a peak list was extracted, containing the peaks in mass-to-charge ratio by revealing their intensities as well. These lists were used to compute a spectral dendrogram and a principle component analysis which displayed the differences among the samples from the two different regions. The results indicate that this technique can be extended with additional tsetse species, ideally with supporting genomic data, to later assist in designing rational vector control strategies.

    The policy of institutional delivery has been the cornerstone of actions aimed at monitoring and achieving MDG 5. Efforts to increase institutional births have been implemented worldwide within different cultural and health systems settings. This paper explores how communities in rural Burkina Faso perceive the promotion and delivery of facility pregnancy and birth care, and how this promotion influences health-seeking behaviour. A qualitative study was conducted in South-Western Burkina Faso between September 2011 and January 2012. A total of 21 in-depth interviews and 8 focus group discussions with women who had given birth recently and community members were conducted. The data were analyzed using qualitative content analysis and interpreted through Merton's concept of unintended consequences of purposive social action. The study found that community members experienced a strong pressure to give birth in a health facility and perceived health workers to define institutional birth as the only acceptable option. Women and their families experienced verbal, economic and administrative sanctions if they did not attend services and adhered to health worker recommendations, and reported that they felt incapable of questioning health workers' knowledge and practices. Women who for social and economic reasons had limited access to health facilities found that the sanctions came with increased cost for health services, led to social stigma and acted as additional barriers to seek skilled care at birth. The study demonstrates how the global and national policy of skilled pregnancy and birth care can occur in unintentional ways in local settings. The promotion of institutional care during pregnancy and at birth in the study area compromised health system trust and equal access to care. The pressure to use facility care and the sanctions experienced by women not complying may further marginalize women with poor access to facility care and contribute to worsened health

  11. NGO-provided free HIV treatment and services in Burkina Faso: scarcity, therapeutic rationality and unfair process

    2012-01-01

    Until 2010, Burkina Faso was an exception to the international trend of abolishing user fees for antiretroviral treatment (ART). Patients were still expected to pay 1,500F CFA (2 Euros) per month for ART. Nevertheless, many non-governmental organizations (NGOs) exempted patients from payment. The objective of this study was to investigate how NGOs selected the beneficiaries of payment exemptions for government-provided ART and rationed out complementary medical and psychosocial services. For this qualitative study, we conducted 13 individual interviews and three focus group discussions (n = 13 persons) with program staff in nine NGOs (4,000 patients), two NGO coordinating structures and one national program. These encounters were recorded and transcribed, and their content was thematically analyzed. The results were presented to the NGOs for feedback. Results indicate that there are no concrete guidelines for identifying patients warranting payment exemptions. Formerly, ART was scarce in Burkina Faso and the primary criterion for treatment selection was clinical. Our results suggest that this scarcity, mediated by an approach we call sociotherapeutic rationality (i.e. maximization of clinical success), may have led to inequities in the provision of free ART. This approach may be detrimental to assuring equity since the most impoverished lack resources to pay for services that maximize clinical success (e.g. viral load) that would increase their chances of being selected for treatment. However, once selected into treatment, attempts were made to ration-out complementary services more equitably. This study demonstrates the risks entailed by medication scarcity, which presents NGOs and health professionals with impossible choices that run counter to the philosophy of equity in access to treatment. Amid growing concerns of an international funding retreat for ART, it is important to learn from the past in order to better manage the potentially inequitable consequences

    Background There are more than 40 Health and Demographic Surveillance System (HDSS) sites in 19 different countries. The running costs of HDSS sites are high. The financing of HDSS activities is of major importance, and adding external health surveys to the HDSS is challenging. To investigate the ways of improving data quality and collection efficiency in the Nouna HDSS in Burkina Faso, the stand-alone data collection activities of the HDSS and the Household Morbidity Survey (HMS) were integrated, and the paper-based questionnaires were consolidated into a single tablet-based questionnaire, the Comprehensive Disease Assessment (CDA). Objective The aims of this study are to estimate and compare the implementation costs of the two different survey approaches for measuring population health. Design All financial costs of stand-alone (HDSS and HMS) and integrated (CDA) surveys were estimated from the perspective of the implementing agency. Fixed and variable costs of survey implementation and key cost drivers were identified. The costs per household visit were calculated for both survey approaches. Results While fixed costs of survey implementation were similar for the two survey approaches, there were considerable variations in variable costs, resulting in an estimated annual cost saving of about US$45,000 under the integrated survey approach. This was primarily because the costs of data management for the tablet-based CDA survey were considerably lower than for the paper-based stand-alone surveys. The cost per household visit from the integrated survey approach was US$21 compared with US$25 from the stand-alone surveys for collecting the same amount of information from 10,000 HDSS households. Conclusions The CDA tablet-based survey method appears to be feasible and efficient for collecting health and demographic data in the Nouna HDSS in rural Burkina Faso. The possibility of using the tablet-based data collection platform to improve the quality of population health

  14. Equivalent susceptibility of Anopheles gambiae M and S molecular forms and Anopheles arabiensis to Plasmodium falciparum infection in Burkina Faso

    2013-01-01

    Background The Anopheles gambiae sensu lato (s.l.) species complex in Burkina Faso consists of Anopheles arabiensis, and molecular forms M and S of Anopheles gambiae sensu stricto (s.s.). Previous studies comparing the M and S forms for level of infection with Plasmodium falciparum have yielded conflicting results. Methods Mosquito larvae were sampled from natural pools, reared to adulthood under controlled conditions, and challenged with natural P. falciparum by experimental feeding with blood from gametocyte carriers. Oocyst infection prevalence and intensity was determined one week after infection. DNA from carcasses was genotyped to identify species and molecular form. Results In total, 7,400 adult mosquitoes grown from wild-caught larvae were challenged with gametocytes in 29 experimental infections spanning four transmission seasons. The overall infection prevalence averaged 40.7% for A. gambiae M form, 41.4% for A. gambiae S form, and 40.1% for A. arabiensis. There was no significant difference in infection prevalence or intensity between the three population groups. Notably, infection experiments in which the population groups were challenged in parallel on the same infective blood displayed less infection difference between population groups, while infections with less balanced composition of population groups had lower statistical power and displayed apparent differences that fluctuated more often from the null average. Conclusion The study clearly establishes that, at the study site in Burkina Faso, there is no difference in genetic susceptibility to P. falciparum infection between three sympatric population groups of the A. gambiae s.l. complex. Feeding the mosquito groups on the same infective blood meal greatly increases statistical power. Conversely, comparison of the different mosquito groups between, rather than within, infections yields larger apparent difference between mosquito groups, resulting from lower statistical power and greater noise

    Objectives To evaluate the epidemiological evolution of patients with HIV (PtHIV), between 2002 and 2012, in a day-hospital that became an HIV reference centre for south-west Burkina Faso. Materials and Methods This was a retrospective study of PtHIV followed in the Bobo Dioulasso university hospital since 2002. The study was based on clinical data recorded using ESOPE software and analysed using Excel and SAS. Results A total of 7320 patients have been treated at the centre since 2002; the active file of patients increased from 147 in 2002 to 3684 patients in 2012. Mean age was stable at 38.4 years and the majority were female (71%). The delay to initiation of antiretroviral (ARV) treatment after HIV diagnosis decreased from 12.9 months in 2002 to 7.2 months in 2012. The percentage of PtHIV lost to follow-up, untreated for HIV and deaths all decreased after 2005. Voluntary anonymous screening and/or an evocative clinical picture were the main reasons for HIV diagnosis, usually at a late stage (41.1% at WHO stage 3). Virological success increased due to a decrease in time to initiation of ARV treatment and an increase in percentage of patients treated (90.5% in 2012, mainly with 1st line drugs). However, there was also a slight increase in the rate of therapeutic failures and the percentage of patients who progressed to 2nd or 3rd line-ARVs. Conclusion Our day-hospital is a good example of the implementation of a specialist centre for the management of PtHIV in a resource-limited country (Burkina Faso). PMID:25970181

    In Burkina-Faso, urban vegetable agriculture is often characterized by urban solid waste fertilizer inputs containing heavy metals such as Cu and Cd. Thus, the relevance of surrounding urban vegetable plots with vetiver hedges to reduce environmental pollution by Cu and Cd was investigated by adsorption studies and pot experiments. Vetiver biomass, its metal contents and, its total and MgCl2 extractable soil metals were monitored over 6months in the presence of a mixture of metal at two concentrations: 2-10 and 100-500mgkg(-1), for Cd and Cu, respectively. The Freundlich adsorption coefficient (Kf) values increased after vetiver growth and were significantly higher for vertisol than for lixisol. After 6months, the vetiver that was grown on lixisol accumulated more metal, increasing up to 4635mgkg(-1) for Cu and to 21.8mgkg(-1) for Cd, than did the vetiver that was grown on vertisol, increasing up to 1534mgkg(-1) for Cu and to 7.2mgkg(-1) for Cd. The metal bioconcentration factor, which was significantly higher for Cd, increased with the applied concentration and ranged from 1.6 to 14 for Cu and from 2.3 to 22 for Cd. Additionally, the translocation factors were higher for Cd (0.38-7.3) than for Cu (0.07-2.6), and the translocation was easiest from lixisol than from vertisol. Thus our results demonstrate the ability of vetiver for Cu and Cd phytoremediation in Burkina Faso soils. Nevertheless, these results should be confirmed across the field to advocate the establishment of vetiver hedges.

    The Oudalan-Gorouol Greenstone Belt (OGGB) forms part of the Palaeoproterozoic as the Baoulé-Mossi domain of the West African Craton (WAC) and hosts gold deposits at Essakane, Gossey, Korizena, and Falagountou in NE Burkina Faso, and Kossa goldfield in Niger. The Birimian supracrustal sequences in the OGGB are dominated by meta-volcanoclastic greywacke intercalated meta-conglomerate, siltstone and shale, carbonate (dolomite) and volcanic units pillow basalts). The belt is surrounded by plutonic rocks including granite, TTG suite granitoids and granite gneiss. The sequences where subjected to two phases of deformation, and several phases of contact metamorphosed to hornblende-hornfels facies during emplacement of pyroxenite-gabbro-norite, granodiorite-tonalite and gabbro dykes and porphyritic sills. The OGGB is bounded and/or crosscut by several major NNE to NE-trending shear zones including the steeply east-dipping Markoye Shear Zone (western margin of the OGGB), Tin Takanet-Bellekcire Shear Zone, Dori Shear Zone, Kargouna Shear Zone, Takabougou Shear Zone, and Bom Kodjelé Shear Zone (transects the centre of the OGGB). The structures were readily identified using LANDSAT, Aster, aeromagnetic and RTP magnetic data, with follow-up strategic mapping, highlighting the value of interpreting geophysical and remotely sensed data in regional mapping in Burkina Faso and Niger. Structural studies completed in 2007 adjacent to the Essakane gold mine indicated that the NE-trending, first-order crustal-scale Markoye Shear Zone (MSZ) has undergone at least two phases of reactivation concomitant to two phases of regional deformation (Tshibubudze et al., 2009). The first phase of deformation, D1, resulted in the formation of NNW-NW trending folds and thrusts during dextral-reverse displacement on the MSZ. The deformation predates the Eburnean Orogeny is termed the Tangaean Event (meaning low hills in the Moré language of Burkina Faso) and is tentatively dated at ca. 2170

    Termites are important ecosystem-engineers in subtropical and tropical regions. The effect of termite activity affecting soil infiltration is well documented in the Sahelian region. Most studies find increased infiltration rates on surfaces that are affected by termite activity in comparison to crusted areas showing non-termite presence. Crusted agricultural fields in the Sanmatenga region in Burkina Faso with clear termite activity were compared to control fields without visual ground dwelling termite activity. Fine scale rainfall simulations were carried out on crusted termite affected and control sites. Furthermore soil moisture change, bulk density, soil organic matter as well as general soil characteristics were studied. The top soils in the study area were strongly crusted (structural crust) after the summer rainfall and harvest of millet. They have a loamy sand texture underlain by a shallow sandy loam Bt horizon. The initial soil moisture conditions were significantly higher on the termite plots when compared to control sites. It was found that the amount of runoff produced on the termite plots was significantly higher, and also the volumetric soil moisture content after the experiments was significantly lower if compared to the control plots. Bulk density showed no difference whereas soil organic matter was significantly higher under termite affected areas, in comparison to the control plots. Lab tests showed no significant difference in hydrophobic behavior of the topsoil and crust material. Micro and macro-structural properties of the topsoil did not differ significantly between the termite sites and the control sites. The texture of the top 5 cm of the soil was also found to be not significantly different. The infiltration results are contradictory to the general literature, which reports increased infiltration rates after prolonged termite activity although mostly under different initial conditions. The number of nest entrances was clearly higher in

    Introduction La tuberculose constitue toujours un problème de santé publique. Sa localisation péricardique reste fréquente. L’objectif de cette étude rétrospective descriptive était de décrire les caractéristiques cliniques et évolutives des cas de péricardites tuberculeuses dans le service de cardiologie du centre hospitalier universitaire de Bobo-Dioulasso. Méthodes Nous avons mené une étude rétrospective descriptive des cas de péricardite tuberculeuse colligés en deux ans à partir des dossiers et registres dans le service de cardiologie du CHU de Bobo-Dioulasso de janvier 2009 à décembre 2010. Résultats De janvier 2009 à décembre 2010, parmi 945 hospitalisations dans le service de cardiologie, une péricardite tuberculeuse a été diagnostiquée chez dix patients âgés de 18 à 82 ans. L’âge moyen était de 46,8±25 ans avec un sexe ratio de un. Soixante pour cent des patients avaient moins de 40 ans. Tous les patients avaient un niveau socio-économique bas. Une notion de contage tuberculeux a été retrouvée chez six patients. Trois patients présentaient une tuberculose pulmonaire à microscopie positive. L’insuffisance cardiaque était constante chez tous les patients avec deux cas de tamponnade à l’admission ayant nécessité une ponction péricardique d’urgence. Tous les patients avaient une sérologie VIH négative. L’échocardiographie a été importante pour le diagnostic positif et dans la prise en charge. L’évolution sous traitement antituberculeux et de l’IC a été bonne chez neuf patients à la fin de la première phase du traitement antituberculeux. Un cas de décès a cependant été enregistré chez un patient avec une HTA déjà compliquée d’accident vasculaire cérébrale ischémique. Conclusion Les péricardiques tuberculeuses sont fréquentes au Burkina Faso. Elles touchent surtout les sujets jeunes et un intérêt particulier devrait être accordé au dépistage et au traitement précoce des

    Background The quality of health care depends on the competence and motivation of the health workers that provide it. In the West, several tools exist to measure worker motivation, and some have been applied to the health sector. However, none have been validated for use in sub-Saharan Africa. The complexity of such tools has also led to concerns about their application at primary care level. Objective To develop a common instrument to monitor any changes in maternal and neonatal health (MNH) care provider motivation resulting from the introduction of pilot interventions in rural, primary level facilities in Ghana, Burkina Faso, and Tanzania. Design Initially, a conceptual framework was developed. Based upon this, a literature review and preliminary qualitative research, an English-language instrument was developed and validated in an iterative process with experts from the three countries involved. The instrument was then piloted in Ghana. Reliability testing and exploratory factor analysis were used to produce a final, parsimonious version. Results and discussion This paper describes the actual process of developing the instrument. Consequently, the concepts and items that did not perform well psychometrically at pre-test are first presented and discussed. The final version of the instrument, which comprises 42 items for self-assessment and eight for peer-assessment, is then shown. This is followed by a presentation and discussion of the findings from first use of the instrument with MNH providers from 12 rural, primary level facilities in each of the three countries. Conclusions It is possible to undertake work of this nature at primary health care level, particularly if the instruments are kept as straightforward as possible and well introduced. However, their development requires very lengthy preparatory periods. The effort needed to adapt such instruments for use in different countries within the region of sub-Saharan Africa should not be underestimated. PMID

    2013-01-01

    Background The conjugate vaccine against serogroup A Neisseria meningitidis (NmA), MenAfriVac, was first introduced in mass vaccination campaigns of the 1-29-year-olds in Burkina Faso in 2010. The aim of this study was to genetically characterize meningococcal isolates circulating in Burkina Faso before and up to 13 months after MenAfriVac mass vaccination. Methods A total of 1,659 meningococcal carriage isolates were collected in a repeated cross-sectional carriage study of the 1-29-year-olds in three districts of Burkina Faso in 2010 and 2011, before and up to 13 months after mass vaccination. Forty-two invasive isolates were collected through the national surveillance in Burkina Faso in the same period. All the invasive isolates and 817 carriage isolates were characterized by serogroup, multilocus sequence typing and porA-fetA sequencing. Results Seven serogroup A isolates were identified, six in 2010, before vaccination (4 from carriers and 2 from patients), and one in 2011 from an unvaccinated patient; all were assigned to sequence type (ST)-2859 of the ST-5 clonal complex. No NmA carriage isolate and no ST-2859 isolate with another capsule were identified after vaccination. Serogroup X carriage and disease prevalence increased before vaccine introduction, due to the expansion of ST-181, which comprised 48.5% of all the characterized carriage isolates. The hypervirulent serogroup W ST-11 clone that was responsible for most of meningococcal disease in 2011 and 2012 was not observed in 2010; it appeared during the epidemic season of 2011, when it represented 40.6% of the serogroup W carriage isolates. Conclusions Successive clonal waves of ST-181 and ST-11 may explain the changing epidemiology in Burkina Faso after the virtual disappearance of NmA disease and carriage. No ST-2859 strain of any serogroup was found after vaccination, suggesting that capsule switching of ST-2859 did not occur, at least not during the first 13 months after vaccination. PMID:23914778

  4. An implementation evaluation of a policy aiming to improve financial access to maternal health care in Djibo district, Burkina Faso

    2012-01-01

    Background To bring down its high maternal mortality ratio, Burkina Faso adopted a national health policy in 2007 that designed to boost the assisted delivery rate and improving quality of emergency obstetrical and neonatal care. The cost of transportation from health centres to district hospitals is paid by the policy. The worst-off are exempted from all fees. Methods The objectives of this paper are to analyze perceptions of this policy by health workers, assess how this health policy was implemented at the district level, identify difficulties faced during implementation, and highlight interactional factors that have an influence on the implementation process. A multiple site case study was conducted at 6 health centres in the district of Djibo in Burkina Faso. The following sources of data were used: 1) district documents (n = 23); 2) key interviews with district health managers (n = 10), health workers (n = 16), traditional birth attendants (n = 7), and community management committees (n = 11); 3) non-participant observations in health centres; 4) focus groups in communities (n = 62); 5) a feedback session on the findings with 20 health staff members. Results All the activities were implemented as planned except for completely subsidizing the worst-off, and some activities such as surveys for patients and the quality assurance service team aiming to improve quality of care. District health managers and health workers perceived difficulties in implementing this policy because of the lack of clarity on some topics in the guidelines. Entering the data into an electronic database and the long delay in reimbursing transportation costs were the principal challenges perceived by implementers. Interactional factors such as relations between providers and patients and between health workers and communities were raised. These factors have an influence on the implementation process. Strained relations between the groups involved may reduce the

    Reported are the results of a cross-sectional survey in Burkina Faso to identify reliable, practical strategies for the serological diagnosis of HIV-1 and/or HIV-2 infections, using less-expensive commercial test kits in various combinations, as an alternative to the conventional Western blot (WB) test, which costs US$ 60. Serum samples, collected from blood donors, patients with acquired immunodeficiency syndrome (AIDS) and pregnant women, were tested between December 1995 and January 1997. Twelve commercial test kits were available: five Mixt enzyme-linked immunosorbent assays (ELISA), three Mixt rapid tests, and four additional tests including monospecific HIV-1 and HIV-2 ELISA. The reference strategy utilized a combination of one ELISA or one rapid test with WB, and was conducted following WHO criteria. A total of 768 serum samples were tested; 35 were indeterminate and excluded from the analysis. Seroprevalence of HIV in the remaining 733 sera was found to be 37.5% (95% confidence interval: 34.0-41.1). All the ELISA tests showed 100% sensitivity, but their specificities ranged from 81.4% to 100%. GLA (Genelavia Mixt) had the highest positive delta value, while ICE HIV-1.0.2 (ICE) produced the most distinct negative results. Among the rapid tests, COM (CombAIDS-RS) achieved 100% sensitivity and SPO (HIV Spot) 100% specificity. Various combinations of commercial tests, according to recommended WHO strategies I, II, III, gave excellent results when ICE was included in the sequence. The best combination of tests for strategy II, which achieved 100% sensitivity and specificity, was to use ICE and COM, the cost of which was US$ 2.10, compared with US$ 55.60 for the corresponding conventional strategy. For strategy III, the best combination, which achieved 100% sensitivity and specificity, was to use ICE, ZYG (Enzygnost Anti HIV-1/HIV-2 Plus) and COM, the cost of which was US$ 2.90 (19.2 times lower than the corresponding strategy requiring WB).

The belt is surrounded by plutonic rocks including granite, TTG suite granitoids and granite gneiss. The sequences where subjected to two phases of deformation, and several phases of contact metamorphosed to hornblende-hornfels facies during emplacement of pyroxenite-gabbro-norite, granodiorite-tonalite and gabbro dykes and porphyritic sills. The OGGB is bounded and/or crosscut by several major NNE to NE-trending shear zones including the steeply east-dipping Markoye Shear Zone (western margin of the OGGB), Tin Takanet-Bellekcire Shear Zone, Dori Shear Zone, Kargouna Shear Zone, Takabougou Shear Zone, and Bom Kodjelé Shear Zone (transects the centre of the OGGB). The structures were readily identified using LANDSAT, Aster, aeromagnetic and RTP magnetic data, with follow-up strategic mapping, highlighting the value of interpreting geophysical and remotely sensed data in regional mapping in Burkina Faso and Niger. Structural studies completed in 2007 adjacent to the Essakane gold mine indicated that the NE-trending, first-order crustal-scale Markoye Shear Zone (MSZ) has undergone at least two phases of reactivation concomitant to two phases of regional deformation (Tshibubudze et al., 2009). The first phase of deformation, D1, resulted in the formation of NNW-NW trending folds and thrusts during dextral-reverse displacement on the MSZ. The deformation predates the Eburnean Orogeny is termed the Tangaean Event (meaning low hills in the Moré language of Burkina Faso) and is tentatively dated at ca. 2170

    In sub-Saharan Africa, various studies have been conducted on severe disability in activities of daily living, instrumental or domestic activities. These studies have reported different rates without describing the social context for understanding their results. This study was conducted in Burkina Faso to fill the gaps in scientific information on disability in these areas. We conducted a cross-sectional descriptive study in Bobo-Dioulasso among the older population, aged 60 and above. Their functional status was evaluated using the Functional Autonomy Measurement System (SMAF). Data analysis was done with the help of Stata. A systematic random sample of 351 aging adults was interviewed. Moderate to severe functional disability or the need for supervision or assistance was present in 7% in activities of daily living and 86% in instrumental or domestic activities of daily living. This need for assistance varied according to the different activities or items in each domain. The proportions of disability found in this study are higher than those of previous studies that measured the often severe disabilities. All persons with disability claimed to have stable human resources which help them to manage their disabilities. The social context instrumental or domestic activities of daily living are divided by generation and/or by sex. That explains some results. With this division, it's inacceptable in some family that elders and/or old men do instrumental or domestic activities of daily living as prepare meals, do laundry, carry water to wash. The variation of this division from one family to another complicates the assessment of functional disability. To best manage elders disabilities, strategies must develop to: 1) retard the resignation of the family in care of its elderly in functional disability, 2) anticipate the preparation of formal social networks, public structures to support the elderly.

    Background Malnutrition is still prevalent worldwide, and its severity, which differs between regions and countries, has led to international organisations proposing its inclusion in the global development framework that will succeed the Millennium Development Goals (post-2015 framework). In Sub-Saharan Africa, malnutrition is particularly severe, among women and children under 5 years. The prevalence of malnutrition has been reported worldwide, differing from region to region and country to country. Nevertheless, little is known about how malnutrition differs between multiple locations along an urban–rural continuum. Objective A survey was carried out in and around Ouagadougou, Burkina Faso, between August and September 2014 to map household nutrition insecurity along the urban–rural continuum, using a transect approach to guide the data collection. Design Transects of 70 km long and 2 km wide directed radially from the city centre outwards were laid, and data were collected from randomly selected households along these transects. Women's dietary diversity scores (WDDSs) were calculated from a sample of 179 women of reproductive age (15–49 years) from randomly selected households. Additionally, anthropometric data (height/length and weight) of 133 children under 5 years of age were collected along the same transects for the computation of anthropometric indices. Results We found that relative proportions of the nutrition indices such as stunting, wasting and underweight varied across the urban–rural continuum. Rural households (15%) had the highest relative proportion of WDDS compared with urban households (11%) and periurban households (8%). There was a significant association between children under 5 years’ nutritional status (wasting, stunting and underweight) and spatial location (p=0.023). The level of agricultural activities is a possible indicator of wasting in children aged 6–59 months (p=0.032). Conclusion Childhood undernutrition certainly

    2012-01-01

    Background Initiatives to raise the quality of care provided to mothers need to be given priority in Sub Saharan Africa (SSA). The promotion of clinical practice guidelines (CPGs) is a common strategy, but their implementation is often challenging, limiting their potential impact. Through a cross-country perspective, this study explored CPGs for maternal health in Burkina Faso, Ghana, and Tanzania. The objectives were to compare factors related to CPG use including their content compared with World Health Organization (WHO) guidelines, their format, and their development processes. Perceptions of their availability and use in practice were also explored. The overall purpose was to further the understanding of how to increase CPGs' potential to improve quality of care for mothers in SSA. Methods The study was a multiple case study design consisting of cross-country comparisons using document review and key informant interviews. A conceptual framework to aid analysis and discussion of results was developed, including selected domains related to guidelines' implementability and use by health workers in practice in terms of usability, applicability, and adaptability. Results The study revealed few significant differences in content between the national guidelines for maternal health and WHO recommendations. There were, however, marked variations in the format of CPGs between the three countries. Apart from the Ghanaian and one of the Tanzanian CPGs, the levels of both usability and applicability were assessed as low or medium. In all three countries, the use of CPGs by health workers in practice was perceived to be limited. Conclusion Our cross-country study suggests that it is not poor quality of content or lack of evidence base that constitute the major barrier for CPGs to positively impact on quality improvement in maternal care in SSA. It rather emphasises the need to prioritise the format of guidelines to increase their usability and applicability and to consider

    Soil erosion is currently menacing the availability of arable land in various countries worldwide. In particular the countries located in the Sahel area of Sub-Saharan Africa are extremely prone to this type of environmental degradation. The same countries rely traditionally upon subsistence farming, which makes the population more vulnerable to environmental changes. The study here presented exploits remote sensed data for identifying the main degradation processes occurring in a small catchment of central Burkina Faso (i.e., Boulbi watershed). This catchment, approximately 100 square km large, is characterized by the presence of a 30 years old dam, whose reservoir feeds 80 ha of rice-fields. This produce contributes up to 13% of the regional rice production. Nonetheless other crops, along with rain-fed rice, are grown all across the Boulbi catchment during the rainy season. Both the increasing gully erosion and the urbanization of the capital city pushing from the North are significantly threatening the farming activities. By using aerial frames acquired with a 16 years' time interval (i.e., 1996, 2012), free satellite imagery, and field surveys, the base cartography of the investigated area was updated and the most active gullies were identified. Moreover a change detection analysis was performed on both artifacts and land use features. More than 200.000 square m of erosion areas and an increase of nearly 90% in built-up areas were detected. In addition, the importance of producing up-to-date base data was proven by the exploitation of the outcomes for the production of a catchment land and water management plan.

    OBJECTIVE: To gauge the effects of operating the Bamako Initiative in Kongoussi district, Burkina Faso. METHODS: Qualitative and quasi-experimental quantitative methodologies were used. FINDINGS: Following the introduction of fees-for-services in July 1997, the number of consultations for curative care fell over a period of three years by an average of 15.4% at "case" health centres but increased by 30.5% at "control" health centres. Moreover, although the operational results for essential drugs depots were not known, expenditure increased on average 2.7 times more than income and did not keep pace with the decline in the utilization of services. Persons in charge of the management committees had difficulties in releasing funds to ensure access to care for the poor. CONCLUSION: The introduction of fees-for-services had an adverse effect on service utilization. The study district is in a position to bear the financial cost of taking care of the poor and the community is able to identify such people. Incentives must be introduced by the state and be swiftly applied so that the communities agree to a more equitable system and thereby allow access to care for those excluded from services because they are unable to pay.

    A photovoltaic (PV) system powering a grain mill and water pump was installed in the remote African village of Tangaye, Burkina Faso (formerly Upper Volta) under the sponsorship of the U.S. Agency for International Development (AID) and by the National Aeronautics and Space Administration (NASA) Lewis Research Center (LeRC) in early 1979. The presence reports covers the second two years of operation from April 1981 through June 1983. During this time, the grain mill and water pump were operational 96 and 88 percent of the time respectively, and the PV system generated sufficient electricity to enable the grinding of about 111 metric tons of finely ground flow and the pumping of over 5000 cm sq of water from the 10 m deep well. The report includes a description of the current configuration of the system, a review of system performance, a discussion of the socioeconomic impact of the system on the villagers and a summary of results and conclusions covering the entire four-year period.

    Essential oils have a significant role in the society where they are variously used in fields such as medicine, pharmacy, cosmetics, chemical and food-processing industries. This justifies interest which they cause and thus systematic studies are undertaken on aromatic species, allowing without any doubt their use advisedly. This study concerns the characterization of the essential oil of Cymbopogon schoenanthus of Burkina Faso, extracted by drive with the water vapor in a distillation operation. The analysis of the chemical composition is carried out by Gas Chromatography. It shows that the 16 made up ones identified account for 65. 2% of the essential oil composition. These compounds belong to the two classes regularly met in essential oils: the mono ones and sesquiterpenes. However, proportion of monoterpenes (53. 2%) is higher than that of sesquiterpenes (12%). Among the identified compounds two monoterpenes (the piperitone and δ-2-carene) remain the principal components in the essential oil. Then the authors determine the density d = 0.9057 by double weighing, the optical activity α = +28.175 by polarimetry and the refractive index n = 1.465 by an interferometric method which they describe. Cymbopogon schoenanthus is an aromatic plant of the family of Poaceae very often used in traditional pharmacopoeia for internal as well as external treatments.

    A cellulose acetate electrophoresis system was used to study the isozyme polymorphism of the Anopheles gambiae complex in a rural village and a city in southwestern Burkina Faso. In both areas A. gambiae Giles was the dominant species (95%) whereas A. arabiensis Patton represented only 5%. Both species were separated readily by octanol dehydrogenase Odh and mannose phosphate isomerase (Mpi) even if they shared some alleles at these two loci. Polymorphism analysis (13 loci) at the intraspecific level of A. gambiae showed a significant difference between the specimens collected in the city from those collected in the village in their allelic and genotypic frequencies of isocitrate dehydrogenase-1 and malate dehydrogenase-1 and in their allelic frequencies for Mpi. No genetic difference was observed between the human biting A. gambiae collected inside or outside the houses in either the village or the city. The Plasmodium falciparum-infected A. gambiae differed from the noninfected ones in their allelic and genotypic frequencies at Mpi and acid phosphatase (Acp). A two-fold difference in infection rate was found for the genotype Mpi130/130 and Acp110/100 compared with other genotypes. However, infected anophelines were found in all genotypes that belonged to these two enzyme systems. Consequently, no refractory mechanism occurs in these natural populations.

    The HIV epidemic has had a profound impact on people's everyday life in most African societies. A large proportion of all new HIV infections involves young people between 15 and 25 years. The objective of this paper is to explore local moral worlds of young people in Bobo-Dioulasso, Burkina Faso, and discuss how the HIVS epidemic affects their reflections on their everyday life and their perceptions of sexual relationships. Based on anthropological fieldwork, including focus-group discussions, in-depth interviews and participant observation, a total of 57 young people between 15 and 25 years were followed over a 3-month period. Using the notion of 'lifestyle', the paper shows how structural factors of unemployment and poverty paired with global discourse on AIDS present the young people with frustrations and quandaries in relation to their hopes and images of love, faithfulness and modern living. The data shows that the HIV epidemic contributes to and accelerates their feeling of living in a risk society and of being at risk. In order to cope with these uncertainties and contingencies, local discourses of trust and fidelity become extremely important and to most young people HIV prevention is synonymous with finding a faithful partner and/or using condoms.

    A series of investigations concerning snakebites and management of envenomations was carried out from 1981 to 2000 in the medical District of Dano, Province of loba in Burkina Faso. Viper bites were more frequent than Elapid ones. The seasonal distribution of the envenomations reflected the cycle of field work and other specific activities. Care seeking within the Traditional System of Health Care (STSS) was more frequent than within the Conventional System of Health Care (SCSS). Lethality was higher at STSS level in cases of viper bites and, conversely, higher in SCSS in the cases of Elapid envenomations. This highlighted the interest in medicinal plants for treating snakebites particularly in case of neurotoxic envenomation. We classified several dozens medicinal plants within an inventory. Some of them have been studied and deemed worthy of interest. Others are used for the treatment of other types of poisoning (pesticides, plants toxic) and/or used in traditional rites. We hope to follow the Côte d'Ivoire experience such that African snake venom, neutralised by modern antivenom, might also be neutralised by the African natural resources.

    In Burkina Faso, the Mouhoun river basin (formerly "Black Volta") constitutes a historical focus of Human (HAT) and Animal (AAT) African Trypanosomoses, both transmitted by tsetse flies. Nowadays, HAT seems to have disappeared from this area, while AAT still causes severe economic losses. In order to explain these different epidemiological situations, we undertook a geographical study based on the analysis of aerial pictures between 1952 and 2007, and field surveys to collect medical, entomological, and veterinary data on trypanosomoses. Our results suggest that in this area, landscapes have been dramatically modified as a consequence of population growth, and in turn have had an impact on the number and distribution of tsetse flies. Combined with the historical medical action on HAT which probably led to the disappearance of T. b. gambiense, this environmental degradation and the development of hydrological structures provide explanations for the local disappearance of HAT, and for the maintenance of AAT. It appears necessary to extrapolate these studies to other areas in order to identify the factors explaining the presence/absence of trypanosomoses in the context of human population growth and climatic changes, in order to help to target priority areas for the control of these diseases.

    The center for rehabilitation and fitting of the disabled in Bogande, Burkina Faso has been in operation since 1992. It was created by a non-governmental organization named Actions de Solidarité Internationale (ASI). The primary goal of the center is to provide support devices to restore upright position and mobility and allow social reinsertion especially for disabled persons between the ages of 0 and 20 years. Approximately one hundred people are treated annually. Treatment is delivered either directly in villages or in dispensaries if the disabled person can be brought in with the assistance of family members or health care workers. This policy has enhanced the quality of information, training, and prevention. Patients with severe disabilities beyond the scope of treatment at the center are contraindicated. The activities of the center have been organized with a view to covering costs. A welding shop has been set up to produce aid devices and provide revenues to pay for some services. The major lessons of this experience involve the need for active recruitment in villages, for contraindicating patients with severe untreatable disability, for developing economically sustainable programs, for training management staff, and for good financial planning. In 4 years of operation, the rehabilitation and fitting center has demonstrated its ability to meet the needs of the disabled in Bogande.

    Water scarcity constrains the livelihoods of millions of people in tropical drylands. Tree planting in these environments is generally discouraged due to the large water consumption by trees, but this view may neglect their potential positive impacts on water availability. The effect of trees on soil hydraulic properties linked to groundwater recharge is poorly understood. In this study, we performed 18 rainfall simulations and tracer experiments in an agroforestry parkland in Burkina Faso to investigate the effect of trees and associated termite mounds on soil infiltrability and preferential flow. The sampling points were distributed in transects each consisting of three positions: (i) under a single tree, (ii) in the middle of an open area, and (iii) under a tree associated with a termite mound. The degree of preferential flow was quantified through parameters based on the dye infiltration patterns, which were analyzed using image analysis of photographs. Our results show that the degree of preferential flow was highest under trees associated with termite mounds, intermediate under single trees, and minimal in the open areas. Tree density also had an influence on the degree of preferential flow, with small open areas having more preferential flow than large ones. Soil infiltrability was higher under single trees than in the open areas or under trees associated with a termite mound. The findings from this study demonstrate that trees have a positive impact on soil hydraulic properties influencing groundwater recharge, and thus such effects must be considered when evaluating the impact of trees on water resources in drylands.

    The New Misola consists of millet soybean, peanut, vitamins, minerals, and industrial amylase. Our objective is to demonstrate that porridge made from local grains and legumes restores the nutritional balance of malnourished children. The study was carried on 304 malnourished children aged 6–48 months including 172 girls and 132 boys from Saint Camille Medical Centre. At the beginning, these malnourished children had a WHZ z-score of −3.10 and a WAZ z-score of −3.85, which reflected, according to WHO, a severe malnutrition. After eight weeks of nutritional rehabilitation, a normal WHZ of −1.41 was obtained. These children recovered more than those in a similar study performed in 2006 with the old formula of Misola. This study shows that malnutrition remains a public health problem in Burkina Faso. It should be necessary that public health services and the epidemiologists work in synergy with nutritionists and “nutrigenetics” in order to combat malnutrition efficiently. PMID:22175011

    Organizational changes, increased funding and the demands of HIV antiretroviral (ARV) treatment create particular challenges for governance in the health sector. We assess resource allocation, policy making and integration of the national responses to ARV provision and reproductive health in Burkina Faso, using national and district budgets related to disease burden, policy documents, organizational structures, and coordination and implementation processes. ARV provision represents the concept of a "crisis scenario", in which reforms are pushed due to a perception of urgent need, whereas the national reproductive health programme, which is older and more integrated, represents a "politics-as-usual scenario". Findings show that the early years of the national response to HIV and AIDS were characterized by new institutions with overlapping functions, and failure to integrate with and strengthen existing structures. National and district budget allocations for HIV compared to other interventions were disproportionately high when assessed against burden of disease. Strategic documents for ARV provision were relatively less developed and referred to, compared to those of the Ministry of Health Directorates for HIV and for Family Health and district health planning teams for reproductive health services. Imbalances and new structures potentially trigger important adverse effects which are difficult to remedy and likely to increase due to the dynamics they create. It therefore becomes crucial, from the outset, to integrate HIV/AIDS funding and responses into health systems.

    Systematic evaluation of food security throughout the West African Sahel has been attempted for nearly two decades. Food security analyses use food prices to determine the ability of the population to access food, and satellite derived vegetation indices to establish how much food is available each year. The relationship between these different food security indicators was explored in this study using correspondence analysis and through the use of Markov chain models. Two sources of quantitative data were used in these analysis that are readily available: 8km normalized difference vegetation index (NDVI) data from the NOAA series of satellites carrying the Advanced Very High Resolution Radiometers (AVHRR), and monthly millet grain prices from 445 markets in Mali, Niger and Burkina Faso. The results of this study show that the quality of the growing season affects the price of millet at the annual and the seasonal time scales. If the growing season was characterized by erratic, sparse rainfall it resulted in higher prices, and well- distributed, abundant rainfall resulted in lower prices. Model output was used to determine the impact of coupled price pressure and production deficits on the livelihoods of three demographic groups in Niger, demonstrating the power of integrating disparate datasets for food security estimation. The model can be used to estimate the economic and societal impacts resulting from climate variation, causing significant changes in human consumptions patterns. These changes can have global consequences when drought affects large portions of the growing regions simultaneously in the same year.

    OBJECTIVE: To quantify the extent of catastrophic household health care expenditure and determine the factors responsible for it in Nouna District, Burkina Faso. METHODS: We used the Nouna Health District Household Survey to collect data on 800 households during 2000-01 for our analysis. The determinants of household catastrophic expenditure were identified by multivariate logistic regression method. FINDINGS: Even at very low levels of health care utilization and modest amount of health expenditure, 6-15% of total households in Nouna District incurred catastrophic health expenditure. The key determinants of catastrophic health expenditure were economic status, household health care utilization especially for modern medical care, illness episodes in an adult household member and presence of a member with chronic illness. CONCLUSION: We conclude that the poorest members of the community incurred catastrophic health expenses. Setting only one threshold/cut-off value to determine catastrophic health expenses may result in inaccurate estimation leading to misinterpretation of important factors. Our findings have important policy implications and can be used to ensure better access to health services and a higher degree of financial protection for low-income groups against the economic impact of illness.

    Background Vertical human immunodeficiency virus (HIV) transmission is a public health problem in Burkina Faso. The main objective of this study on the prevention of mother-to-child HIV-1 transmission was to determine the residual risk of HIV transmission in infants born to mothers receiving highly active antiretroviral therapy (HAART). Moreover, we detect HIV antiretroviral (ARV) drug resistance among mother–infant pairs and identify subtypes and circulating recombinant forms (CRF) in Burkina Faso. Design In this study, 3,215 samples of pregnant women were analyzed for HIV using rapid tests. Vertical transmission was estimated by polymerase chain reaction in 6-month-old infants born to women who tested HIV positive. HIV-1 resistance to ARV, subtypes, and CRFs was determined through ViroSeq kit using the ABI PRISM 3,130 sequencer. Results In this study, 12.26% (394/3,215) of the pregnant women were diagnosed HIV positive. There was 0.52% (2/388) overall vertical transmission of HIV, with rates of 1.75% (2/114) among mothers under prophylaxis and 0.00% (0/274) for those under HAART. Genetic mutations were also isolated that induce resistance to ARV such as M184V, Y115F, K103N, Y181C, V179E, and G190A. There were subtypes and CRF of HIV-1 present, the most common being: CRF06_CPX (58.8%), CRF02_AG (35.3%), and subtype G (5.9%). Conclusions ARV drugs reduce the residual rate of HIV vertical transmission. However, the virus has developed resistance to ARV, which could limit future therapeutic options when treatment is needed. Resistance to ARV therefore requires a permanent interaction between researchers, physicians, and pharmacists, to strengthen the network of monitoring and surveillance of drug resistance in Burkina Faso.

    Background In Burkina Faso, Ghana and Tanzania strong efforts are being made to improve the quality of maternal and neonatal health (MNH) care. However, progress is impeded by challenges, especially in the area of human resources. All three countries are striving not only to scale up the number of available health staff, but also to improve performance by raising skill levels and enhancing provider motivation. Methods In-depth interviews were used to explore MNH provider views about motivation and incentives at primary care level in rural Burkina Faso, Ghana and Tanzania. Interviews were held with 25 MNH providers, 8 facility and district managers, and 2 policy-makers in each country. Results Across the three countries some differences were found in the reasons why people became health workers. Commitment to remaining a health worker was generally high. The readiness to remain at a rural facility was far less, although in all settings there were some providers that were willing to stay. In Burkina Faso it appeared to be particularly difficult to recruit female MNH providers to rural areas. There were indications that MNH providers in all the settings sometimes failed to treat their patients well. This was shown to be interlinked with differences in how the term ‘motivation’ was understood, and in the views held about remuneration and the status of rural health work. Job satisfaction was shown to be quite high, and was particularly linked to community appreciation. With some important exceptions, there was a strong level of agreement regarding the financial and non-financial incentives that were suggested by these providers, but there were clear country preferences as to whether incentives should be for individuals or teams. Conclusions Understandings of the terms and concepts pertaining to motivation differed between the three countries. The findings from Burkina Faso underline the importance of gender-sensitive health workforce planning. The training that all

    Plasmodium falciparum Pfcrt-76 and Pfmdr1-86 gene polymorphisms were determined during a clinical trial in Burkina Faso comparing the efficacies of dihydroartemisinin-piperaquine (DHA-PPQ) and artemether-lumefantrine (AL). Significant selection of Pfcrt-K76 was observed after exposure to AL and DHA-PPQ, as well as selection of Pfmdr1-N86 after AL but not DHA-PPQ treatment, suggesting reverse selection on the Pfcrt gene by PPQ. These results support the rational use of DHA-PPQ in settings where chloroquine (CQ) resistance is high. PMID:25403659

    ABSTRACT Objective: To investigate trends in HIV prevalence and changes in reported sexual behaviors between 1998 and 2014 in Burkina Faso. Methods: We obtained data on HIV prevalence from antenatal care (ANC) surveillance sites (N = 9) that were consistently included in surveillance between 1998 and 2014. We also analyzed data on HIV prevalence and reported sex behaviors from 3 population-based surveys from the Demographic and Health Surveys (DHS), conducted in 1998–99, 2003, and 2010. Sex behavior indicators comprised never-married youth who have never had sex; sex with more than 1 partner; sex with a nonmarital, non-cohabiting partner; condom use at last sex with a nonmarital, non-cohabiting partner; and sex before age 15. We calculated survey-specific HIV prevalence with 95% confidence intervals (CIs) and used the chi-square test or chi-square test for trend to compare HIV prevalence across survey years and to analyze trends in reported sex behaviors. Results: HIV prevalence among pregnant women ages 15–49 decreased by 72% in urban areas, from 7.1% in 1998 to 2.0% in 2014, and by 75% in rural areas, from 2.0% in 2003 to 0.5% in 2014. HIV declined most in younger age groups, which is a good reflection of recent incidence, with declines of 55% among 15–19-year-olds, 72% among 20–24-year-olds, 40% among 25–29-year-olds, and 7% among those ≥30 years old (considering urban and rural data combined). Data reported in the DHS corroborated these declines in HIV prevalence: between 2003 and 2010, HIV prevalence dropped significantly—by 89% among girls ages 15–19, from 0.9% (95% CI, 0.2 to 1.6) to 0.1% (95% CI, 0.0 to 0.4), and by 78% among young women ages 20–24, from 1.8% (95% CI, 1.6 to 3.0) to 0.4% (95% CI, 0.0 to 0.7). During the same time period, people reported safer sex behaviors. For example, significantly higher percentages of never-married youth reported they had never had sex, lower percentages of sexually active youth reported multiple

    Objective The study analysed the effect of Information, Education, and Communication (IEC) campaign activities on the adoption of a community-based health insurance (CHI) scheme in Nouna, Burkina Faso. It also identified the factors that enhanced or limited the campaign's effectiveness. Design Complementary data collection approaches were used. A survey was conducted with 250 randomly selected household heads, followed by in-depth interviews with 22 purposively selected community leaders, group discussions with the project management team, and field observations. Bivariate analysis and multivariate logistic regression models were used to assess the association between household exposure to campaign and acquisition of knowledge as well as household exposure to campaign and enrolment. Results The IEC campaign had a positive effect on households’ knowledge about the CHI and to a lesser extent on household enrolment in the scheme. The effectiveness of the IEC strategy was mainly influenced by: (1) frequent and consistent IEC messages from multiple media channels (mass and interpersonal channels), including the radio, a mobile information van, and CHI team, and (2) community heads’ participation in the CHI scheme promotion. Education was the only significantly influential socio-demographic determinant of knowledge and enrolment among household heads. The relatively low effects of the IEC campaign on CHI enrolment are indicative of other important IEC mediating factors, which should be taken into account in future CHI campaign evaluation. Conclusion The study concludes that an IEC campaign is crucial to improving the understanding of the CHI scheme concept, which is an enabler to enrolment, and should be integrated into scheme designs and evaluations.

    This study investigates the long term economic impact of severe obstetric complications for women and their children in Burkina Faso, focusing on measures of food security, expenditures and related quality of life measures. It uses a hospital based cohort, first visited in 2004/2005 and followed up four years later. This cohort of 1014 women consisted of two main groups of comparison: 677 women who had an uncomplicated delivery and 337 women who experienced a severe obstetric complication which would have almost certainly caused death had they not received hospital care (labelled a "near miss" event). To analyze the impact of such near miss events as well as the possible interaction with the pregnancy outcome, we compared household and individual level indicators between women without a near miss event and women with a near miss event who either had a live birth, a perinatal death or an early pregnancy loss. We used propensity score matching to remove initial selection bias. Although we found limited effects for the whole group of near miss women, the results indicated negative impacts: a) for near miss women with a live birth, on child development and education, on relatively expensive food consumption and on women's quality of life; b) for near miss women with perinatal death, on relatively expensive foods consumption and children's education and c) for near miss women who had an early pregnancy loss, on overall food security. Our results showed that severe obstetric complications have long lasting consequences for different groups of women and their children and highlighted the need for carefully targeted interventions.

    Human respiratory syncytial virus (RSV) infections are little known in Burkina Faso. The objective of our work is to study the epidemiological and clinical aspects of RSV infections in infants in the Pediatric Teaching Hospital Charles de Gaulle of Ouagadougou. Between July 1(st) 2010 and June 30(th) 2011, we analyzed by direct immunofluorescence and PCR nasopharyngeal swabs from children from 0 to 36 months old. All in all, 210 patients among whom 74 from the external consultation (35.2%) and 136 hospitalized (64.7%) benefited from a nasopharyngeal aspiration. The motives for consultation were cough (91.7%), rhinitis (79.2%), fever (79.2%) and respiratory distress syndrome (66.7%). The evoked diagnoses were predominantly the acute bronchiolitis in 14 cases (58.3%) followed by the acute pulmonary disease in 7 patients (26.2%) then flue in 1 patient (16.7%). We detected by direct immunofluorescence the antigens of the respiratory viruses in 21 nasopharyngeal aspirations with 10 cases of respiratory syncytial virus (RSV) infections (47.6%). The PCR realized on 208 samples allowed to identify 153 positive samples (73.2%) with 24 RSV, i.e. a global prevalence of 16.1% with a peak of 18 cases (75%). In October, all the patients benefited from an often multiple antibiotic treatment of at least 10 days which was not still necessary. The evolution was favorable for all patients. This study confirms the important place of the viruses which are detected in 70% of the cases. The PCR multiplex, certainly expensive but effective and successful, deserves to be used in our developing countries to avoid the irrational prescription of antibiotic.

    In Burkina Faso, the cyclical vectors of African animal trypanosomoses (AAT) are riverine tsetse species, namely Glossina palpalis gambiensis Vanderplank (G.p.g.) and Glossina tachinoides Westwood (G.t.) (Diptera: Glossinidae). Experimental work demonstrated that environmental stress can increase the sensitivity of tsetse to trypanosome infection. Seasonal variations of the tsetse infection rates were monitored monthly over 17 months (May 2006-September 2007) in two sites (Douroula and Kadomba). In total, 1423 flies were dissected and the infection of the proboscis, middle intestine and salivary glands was noted. All the positive organs were analyzed using monospecific polymerase chain reaction (PCR) primers. To investigate the role of different environmental factors, fly infection rates were analyzed using generalized linear mixed binomial models using the species, sex, and monthly averages of the maximum, minimum and mean daily temperatures, rainfalls, Land Surface Temperature day (LSTd) and night (LSTn) as fixed effects and the trap position as a random effect. The overall infection rate was 10% from which the predominant species was T. congolense (7.6% of the flies), followed by T. vivax (2.2% of the flies). The best model (lowest AICc) for the global infection rates was the one with the maximum daily temperature only as fixed effect (p < 0.001). For T. congolense, the best model was the one with the tsetse species, sex, maximum daily temperature and rainfalls as fixed effect, where the maximum daily temperature was the main effect (p < 0.001). The number of T. vivax infections was too low to allow the models to converge. The maturation rate of T. congolense was very high (94%), and G. t. harbored a higher maturation rate (p = 0.03). The results are discussed in view of former laboratory studies showing that temperature stress can increase the susceptibility of tsetse to trypanosomes, as well as the possibility to improve AAT risk mapping using satellite images.

    Little is known about the costs and consequences of abortions to women and their households. Our aim was to study both costs and consequences of induced and spontaneous abortions and complications. We carried out a cross-sectional study between February and September 2012 in Ouagadougou, the capital city of Burkina Faso. Quantitative data of 305 women whose pregnancy ended with either an induced or a spontaneous abortion were prospectively collected on sociodemographic, asset ownership, medical and health expenditures including pre-referral costs following the patient's perspective. Descriptive analysis and regression analysis of costs were performed. We found that women with induced abortion were often single or never married, younger, more educated and had earlier pregnancies than women with spontaneous abortion. They also tended to be more often under parents' guardianship compared with women with spontaneous abortion. Women with induced abortion paid much more money to obtain abortion and treatment of the resulting complications compared with women with spontaneous abortion: US$89 (44 252 CFA ie franc of the African Financial Community) vs US$56 (27 668 CFA). The results also suggested that payments associated with induced abortion were catastrophic as they consumed 15% of the gross domestic product per capita. Additionally, 11-16% of total households appeared to have resorted to coping strategies in order to face costs. Both induced and spontaneous abortions may incur high expenses with short-term economic repercussions on households' poverty. Actions are needed in order to reduce the financial burden of abortion costs and promote an effective use of contraceptives. PMID:24829315

    Background More than 500 000 young children die from dehydration caused by severe diarrhea each year, globally. Although routine use of oral rehydration solution (ORS) could prevent almost all of these deaths, ORS utilization remains low in many low–income countries. Previous research has suggested that misperceptions among caregivers may be an obstacle to wider use of ORS. Methods To better understand the extent of ORS utilization and the reasons for use or non–use in low–resource settings, the project team conducted a semi–structured, quantitative survey of 400 caregivers in Burkina Faso in 2014. All caregivers had a child below the age of five who had diarrhea lasting 2 days or more in the previous 2 months. Results Although more than 80% of caregivers were aware of ORS, less than half reported using it to treat their child’s diarrhea. Replacing fluids lost due to diarrhea was considered a low priority by most caregivers, and many said they considered antibiotics more effective for treating diarrhea. Users and non–users of ORS held substantially different perceptions of the product, though all caregivers tended to follow recommendations of health care workers. A significant proportion of users reported difficulty in getting a child to drink ORS. Costs and access to ORS were not found to be significant barriers to use. Conclusions Misperceptions among caregivers and health workers contribute to low utilization of ORS. Better caregiver understanding of diarrheal disease and the importance of rehydration, as well as increased recommendation by health workers, will help to increase ORS utilization. Improving product presentation and taste will also help to increase use. PMID:27699000

    In developing countries, prenatal lipid-based nutrient supplements (LNSs) were shown to increase birth size; however, the mechanism of this effect remains unknown. Cord blood hormone concentrations are strongly associated with birth size. Therefore, we hypothesize that LNSs increase birth size through a change in the endocrine regulation of fetal development. We compared the effect of daily prenatal LNSs with multiple micronutrient tablets on cord blood hormone concentrations using a randomized, controlled design including 197 pregnant women from rural Burkina Faso. Insulin-like growth factors (IGF) I and II, their binding proteins IGFBP-1 and IGFBP-3, leptin, cortisol, and insulin were quantified in cord sera using immunoassays. LNS was associated with higher cord blood leptin mainly in primigravidae (+57%; P = 0.02) and women from the highest tertile of BMI at study inclusion (+41%; P = 0.02). We did not find any significant LNS effects on other measured cord hormones. The observed increase in cord leptin was associated with a significantly higher birth weight. Cord sera from small-for-gestational age newborns had lower median IGF-I (-9 μg/L; P = 0.003), IGF-II (-79 μg/L; P = 0.003), IGFBP-3 (-0.7 μg/L; P = 0.007), and leptin (-1.0 μg/L; P = 0.016) concentrations but higher median cortisol (+18 μg/L; P = 0.037) concentrations compared with normally grown newborns. Prenatal LNS resulted in increased cord leptin concentrations in primigravidae and mothers with higher BMI at study inclusion. The elevated leptin concentrations could point toward a higher neonatal fat mass.

    Urine from urine-diversion toilets (UDTs) is routinely used as fertilizer for urban agriculture in Ouagadougou, Burkina Faso. Because urine from UDTs can be accidentally spoiled by feces, we determined whether virulent enteric viruses could persist in urine that is used for agricultural purposes and pose a threat to human health. Urine samples (N = 60) were first collected from 42 UDTs during the months of January and February 2012 in Ouagadougou and screened negative for the presence of norovirus (NoV) and group A rotavirus (RV). Composite urine from five collection sites was used to determine whether spiked murine norovirus (MNV) and group A bovine rotavirus (boRVA) could remain infectious at 15, 25, and 42 °C over an incubation period of 42 days in phosphate buffered saline (control) and urine. For both viruses, infectivity was determined by plaque assay and the presence of viral genome was evaluated by real-time RT-PCR. A decrease in the infectious titer was observed in composite urines that were experimentally seeded with MNV and boRVA. The decrease in the infectious titer was greater for MNV than for boRVA. Given that MNV was more labile to urine than boRVA was, MNV and boRVA genomes were still detectable after the 42 and 49 days incubation period for MNV and boRVA, respectively. Our data using substitutes of human NoV and RV suggested that there is a virucidal activity of urine against RVs and NoVs, given that the effect was lesser for RV. In spite of disappointing results for boRVA, the use of urine as fertilizer is still promising provided that future safety studies are extended to other enteric viruses.

    Water scarcity constrains the livelihoods of millions of people in tropical drylands. Tree planting in these environments is generally discouraged due to the large water consumption by trees, but this view may neglect their potential positive impacts on water availability. The effect of trees on soil hydraulic properties linked to groundwater recharge is poorly understood. In this study, we performed 18 rainfall simulations and tracer experiments in an agroforestry parkland in Burkina Faso to investigate the effect of trees and associated termite mounds on soil infiltrability and preferential flow. The sampling points were distributed in transects each consisting of three positions: (i) under a single tree, (ii) in the middle of an open area, and (iii) under a tree associated with a termite mound. The degree of preferential flow was quantified through parameters based on the dye infiltration patterns, which were analyzed using image analysis of photographs. Our results show that the degree of preferential flow was highest under trees associated with termite mounds, intermediate under single trees, and minimal in the open areas. Tree density also had an influence on the degree of preferential flow, with small open areas having more preferential flow than large ones. Soil infiltrability was higher under single trees than in the open areas or under trees associated with a termite mound. The findings from this study demonstrate that trees have a positive impact on soil hydraulic properties influencing groundwater recharge, and thus such effects must be considered when evaluating the impact of trees on water resources in drylands. Key Points Trees in dryland landscapes increase soil infiltrability and preferential flow Termite mounds in association with trees further enhance preferential flow PMID:25641996

    This study investigates the impacts of land use change on water resources in the Dano catchment, Burkina Faso, using a physically based hydrological simulation model and land use scenarios. Land use dynamic in the catchment was assessed through the analysis of four land use maps corresponding to the land use status in 1990, 2000, 2007, and 2013. A reclassification procedure levels out differences between the classification schemes of the four maps. The land use maps were used to build five land use scenarios corresponding to different levels of land use change in the catchment. Water balance was simulated by applying the Water flow and balance Simulation Model (WaSiM) using observed discharge, soil moisture, and groundwater level for model calibration and validation. Model statistical quality measures (R2, NSE and KGE) achieved during calibration and validation ranged between 0.6 and 0.9 for total discharge, soil moisture, and groundwater level, indicating a good agreement between observed and simulated variables. After a successful multivariate validation the model was applied to the land use scenarios. The land use assessment exhibited a decrease of savannah at an annual rate of 2% since 1990. Conversely, cropland and urban areas have increased. Since urban areas occupy only 3% of the catchment it can be assumed that savannah was mainly converted to cropland. The conversion rate of savannah was lower than the annual population growth of 3%. A clear increase in total discharge (+17%) and decrease in evapotranspiration (-5%) was observed following land use change in the catchment. A strong relationship was established between savannah degradation, cropland expansion, discharge increase and reduction of evapotranspiration. The increase in total discharge is related to high peak flow, suggesting (i) an increase in water resources that are not available for plant growth and human consumption and (ii) an alteration of flood risk for both the population within and

    Molecular epidemiology studies further our understanding of migrations of phytopathogenic bacteria, the major determining factor in their emergence. Asiatic citrus canker, caused by Xanthomonas citri pv. citri, was recently reported in Mali and Burkina Faso, a region remote from other contaminated areas. To identify the origin and pathways of these emergences, we used two sets of markers, minisatellites and microsatellites, for investigating different evolutionary scales. Minisatellite typing suggested the introduction of two groups of strains in Mali (DAPC 1 and DAPC 2), consistent with microsatellite typing. DAPC 2 was restricted to Bamako district, whereas DAPC 1 strains were found much more invasive. The latter strains formed a major clonal complex based on microsatellite data with the primary and secondary founders detected in commercial citrus nurseries and orchards. This suggests that human activities played a major role in the spread of DAPC 1 strains via the movement of contaminated propagative material, further supported by the frequent lack of differentiation between populations from geographically distant nurseries and orchards. Approximate Bayesian Computation analyses supported the hypothesis that strains from Burkina Faso resulted from a bridgehead invasion from Mali. Multi-locus variable number of tandem repeat analysis and Approximate Bayesian Computation are useful for understanding invasion routes and pathways of monomorphic bacterial pathogens.

    The study investigated the prevalence of five major Escherichia coli pathogroups in raw meats and beef intestines sold at the local markets in Ouagadougou, Burkina Faso. One hundred and twenty samples (36 beef, 36 beef intestine, 24 mutton and 24 chicken samples) were purchased from four markets between October 2008 and February 2009. Fifteen virulence genes specific for Shiga toxin-producing E. coli (STEC), enteropathogenic E. coli (EPEC), enterotoxigenic E. coli (ETEC), enteroinvasive E. coli (EIEC) and enteroaggregative E. coli (EAEC) were examined using 16-plex PCR for mixed bacterial cultures derived from the samples. One or more diarrheagenic E. coli pathogroup was detected in 51 (43%) of all the 120 samples: in 16 (44%) beef, 19 (53%) beef intestine, 9 (38%) mutton and in 7 (29%) chicken samples. Thirty three (28%) samples were positive for stx(1) and/or stx(2) indicating presence of STEC. EPEC virulence markers (eae, escV and/or ent and/or bfp and/or EHEC-hlyA) were detected in 14 (12%) stx-negative samples. ETEC virulence markers (elt and/or estIb and/or estIa) were detected in 10 (8%) samples and EAEC virulence markers (pic or aggR) in 5 (4%) samples. No EIEC was detected. The results show that in Burkina Faso the microbiological quality of retail meat is alarmingly poor due to the common occurrence of diarrheagenic E. coli bacteria.

    The association between P. falciparum eba-175, ama-1, and msp-3 polymorphism in the pathogenicity of malaria disease was investigated. We therefore compared the prevalence of different alleles between symptomatic and asymptomatic malarial children under five years of age living in Burkina Faso. Blood filter papers were collected during the 2008 malaria transmission season from 228 symptomatic and 199 asymptomatic children under five years of age. All patients were living in the rural area of Saponé at about 50 km from Ouagadougou, the capital city of Burkina Faso. P. falciparum parasite DNA was extracted using QIAGEN kits and the alleles diversity was assessed by a nested PCR. PCR products were then digested by restriction enzymes based on already described polymorphic regions of the eba-175, ama-1, and msp-3 genes. The individual alleles eba-175_FCR3 and msp-3_K1 frequencies were statistically higher (p < 0.0001) in the asymptomatic group compared to the symptomatic ones. No statistically significant difference was noted in the prevalence of ama-1-3D7, ama-1-K1, and ama-1-HB3 genotypes between the two groups (p > 0.05). The comparative analysis of P. falciparum genotypes indicated that the polymorphism in eba-175 and msp-3 genotypes varied between asymptomatic and symptomatic clinical groups and may contribute to the pathogenesis of malaria.

    OBJECTIVE: To explore the factors that determine whether a patient will initiate treatment within a system of health-care services, and the factors that determine whether the patient will be retained in the chosen system, in Nouna, rural Burkina Faso. METHODS: The data used were pooled from four rounds of a household survey conducted in Nouna, rural Burkina Faso. The ongoing demographic surveillance system provided a sampling framework for this survey in which 800 households were sampled using a two-stage cluster sampling procedure. More than one treatment episode was observed for a single episode of illness per patient. The multinomial logit model was used to explore the determinants of patient initiation to systems of modern, traditional and home treatment, and a binary logit model was used to explore the determinants of patient retention within the chosen health-care provider system. FINDINGS: The results suggest that the determinants of patient initiation and their subsequent retention are different. Household income, education, urban residence and expected competency of the provider are positive predictors of initiation, but not of retention, for modern health-care services. Only perceived quality of care positively predicted retention in modern health-care services. CONCLUSION: Interventions focusing on patient initiation and patient retention are likely to be different. Policies directed at enhancing initiation for modern health-care services would primarily focus on reducing financial barriers, while those directed at increasing retention would primarily focus on attributes that improve the perceived quality of care.

    Liver fibrosis (LF) must be assessed before talking treatment decisions in hepatitis B. In Burkina Faso, liver biopsy (LB) remains the “gold standard” method for this purpose. Access to treatment might be simpler if reliable alternative techniques for LF evaluation were available. The hepatitis B virus (HBV)-infected patients who underwent LB was invited to have liver stiffness measurement (Fibroscan) and serum marker assays. Fifty-nine patients were enrolled. The performance of each technique for distinguishing F0F1 from F2F3F4 was compared. The area under receiver operating characteristic (AUROC) curves was 0.61, 0.71, 0.79, 0.82, and 0.87 for the aspartate transaminase to platelet ratio index (APRI), Fib-4, Fibrotest, Fibrometre, and Fibroscan. Elastometric thresholds were identified for significant fibrosis and cirrhosis. Combined use of Fibroscan and a serum marker could avoid 80% of biopsies. This study shows that the results of alternative methods concord with those of histology in HBV-infected patients in Burkina Faso. These alternative techniques could help physicians to identify patients requiring treatment. PMID:20207872

    Desertification affects about two-thirds of the countries of the world, and one-third of the earth's surface, namely one-fifth of the world population. The seriousness of desertification depends on various factors, including climate (temperature, precipitation, wind, humidity), geomorphological and geological condition, vegetation cover, water and wind erosion, soil nutrient status and salinization, land use and land management, biodiversity, etc. Even the climate changes can contribute to the advance of desertification. Indeed hotter and drier conditions would extend the area prone to desertification to encompass areas currently not at risk. In addition, the rate of desertification would increase due to increases in erosion leading to an irreversible status of desertification process. This study was carried out within the FP7-ENV-2010 CLUVA project (CLimate change and Urban Vulnerability in Africa), and aimed to estimate the effects of climate change on sensitivity to desertification in the area of Ouagadougou (Burkina Faso) providing a prediction tool useful for optimization of land management. The approach was based on the implementation and adaptation to the local conditions of the Environmentally Sensitive Areas Index (ESAI), developed within the MEDALUS project (Mediterranean Desertification and Land Use). A noteworthy advantage of this methodology is the flexibility, that allows to take into account several indices (climate, soil, vegetation cover, land management) operationally defined through the inclusion or exclusion of parameters scored on the basis of their impact on sensitivity to desertification. Therefore, an upgrade of the original method was developed adding a further index (Erosion Quality Index) for the evaluation of the cumulative impact of water and wind erosion in desertification process, by the RUSLE equation and the WEQ method, respectively. Climate simulations over the time period 2010-2050 were provided by the CMCC (Centro Euro

    Background The private medical care sector is expanding in urban cities in Sub-Saharan Africa (SSA). However, people’s health-care-seeking behaviors in this new landscape remain poorly understood; furthermore, distinguishing between public and private providers and among various types of private providers is critical in this investigation. This study assessed, by type, the healthcare providers urban residents in Burkina Faso visit, and their choice determinants. Method We conducted a population-based survey of a representative sample of 1,600 households in Ouagadougou from July to November 2011, consisting of 5,820 adults. We assessed the types of providers people typically sought for severe and non-severe conditions. We applied generalized estimating equations in this study. Results Among those surveyed, 97.7% and 53.1% indicated that they seek a formal provider for treating severe and non-severe conditions, respectively. Among the formal provider seekers, 20.5% and 17.0% chose for-profit (FP) providers for treating severe and non-severe conditions, respectively. Insurance coverage was held by 2.0% of those surveyed. Possessing insurance was the strongest predictor for seeking FP, for both severe (odds ratio [OR] = 1.15, 95% confidence interval [CI] = 1.04–1.28), and non-severe conditions (OR = 1.22, 95% CI = 1.07–1.39). Other predictors included being a formal jobholder and holding a higher level education. By contrast, we observed no significant difference in predisposing, enabling, or need characteristics between not-for-profit (NFP) provider seekers and public provider seekers. Proximity was the primary reason for choosing a provider. Conclusion The results suggested that FP providers play a crucial role in the urban healthcare market in SSA. Socioeconomic status and insurance status are significant predictors of provider choice. The findings can serve as a crucial reference for policymakers in response to the emergence of FP providers in

    Introduction Transgender women are at high risk for the acquisition and transmission of HIV. However, there are limited empiric data characterizing HIV-related risks among transgender women in sub-Saharan Africa. The objective of these analyses is to determine what factors, including sexual behaviour stigma, condom use and engagement in sex work, contribute to risk for HIV infection among transgender women across three West African nations. Methods Data were collected via respondent-driven sampling from men who have sex with men (MSM) and transgender women during three- to five-month intervals from December 2012 to October 2015 across a total of six study sites in Togo, Burkina Faso and Côte d'Ivoire. During the study visit, participants completed a questionnaire and were tested for HIV. Chi-square tests were used to compare the prevalence of variables of interest between transgender women and MSM. A multilevel generalized structural equation model (GSEM) was used to account for clustering of observations within study sites in the multivariable analysis, as well as to estimate mediated associations between sexual behaviour stigma and HIV infection among transgender women. Results In total, 2456 participants meeting eligibility criteria were recruited, of which 453 individuals identified as being female/transgender. Transgender women were more likely than MSM to report selling sex to a male partner within the past 12 months (p<0.01), to be living with HIV (p<0.01) and to report greater levels of sexual behaviour stigma as compared with MSM (p<0.05). In the GSEM, sexual behaviour stigma from broader social groups was positively associated with condomless anal sex (adjusted odds ratio (AOR)=1.33, 95% confidence interval (CI)=1.09, 1.62) and with selling sex (AOR=1.23, 95% CI=1.02, 1.50). Stigma from family/friends was also associated with selling sex (AOR=1.42, 95% CI=1.13, 1.79), although no significant associations were identified with prevalent HIV infection

    The United Nations Convention to Combat Desertification (UNCCD) defines desertification as "land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors, including climatic variations and human activities". Desertification is regarded as one of the major global environmental problems of the 21st century and the African sub-Sahara is often quoted as the most seriously affected region with a significant loss of biological and economic productivity of the land. In this geographic area, desertification processes are usually generated by soil erosion due to climate characteristics and fluctuations, unsustainable land uses, overgrazing and inappropriate agricultural practices. Preventing desertification requires an improved understanding of its causes, impact, degree and association with climate, soil, water, land cover, socio-economic factors and their combined effects. The development of methodologies capable of managing large amounts of data in an integrated approach is needed because of the complexity and variety of forms of desertification processes. The study was carried out within the FP7-ENV-2010 CLUVA project (CLimate change and Urban Vulnerability in Africa), aimed to estimate the sensitivity to land degradation in the urban and peri-urban areas of both Ouagadougou (Burkina Faso) and Saint Louis (Senegal) cities. The approach was based on the implementation and adaptation of the modeling methodology developed within the MEDALUS project (MEditerranean Desertification and Land Use). The model is characterized by a multi-factor approach based on the assessment of both environmental quality indicators (climate, soil, vegetation) and anthropogenic factors (land management). The methodology is adaptable to the local conditions, considering that some key indicators can be operationally defined through the inclusion or exclusion of parameters and the scores assigned in order to match the specific relevance of the factors.

    An arbovirus surveillance was carried out in Burkina Faso from 1983 to 1986. It was based on crepuscular catches of mosquitoes on human bait in some wooded areas and in one town. The total collection was 228 catches with an average of 8 men per catch. The total number of mosquitoes caught was 44,956 among which 32,010 potential vector of yellow fever; all these mosquitoes were analysed for arbovirology. In the south-western part of the country (region of Bobo-Dioulasso), surveillance was conducted each year from August to November, whilst the circulation of Aedes-borne arboviruses is well known to be favoured. In 1983, 1984 and 1986, seven strains of yellow fever virus were isolated in circumstances remarkably similar. They came from selvatic areas and never from the town. They concerned only Aedes (Stegomyia) luteocephalus which is the very predominant potential vector of yellow fever in the region. They were obtained in low figure, between 1 and 4 per year. They occurred from 27th of October to 21th of November. These observations confirm that the southern portion of the Sudan savanna zone of West Africa is the setting of a customary circulation of yellow fever virus and therefore belongs to the endemic emergence zone. In 1986, two strains of dengue 2 virus were isolated. One concerned Ae. luteocephalus from the selvatic area, the other Ae. (St.) aegypti from the heart of town. These data suggest two distinct cycles for dengue 2 virus, one urban and one selvatic, which could coexist simultaneously in the same region. In the south-eastern part of the country (region of Fada-N'Gourma) a yellow fever epidemic occurred between September and December 1983; its study has enable to precise their entomological aspects. The entomological inoculation rate of yellow fever virus has been evaluated to 22 infected bites per man during the month of october, for a man living close to forest gallery. 25 strains of yellow fever virus strains was isolated from Ae.

    SummaryThe knowledge about groundwater flow conditions within the Southeastern Taoudeni Basin Aquifer shared by Burkina Faso and Mali is relatively limited with very little information on potentiometric heads, recharge processes, residence time and water quality. A better evaluation of groundwater resources in this area is a strategic point for water resources management in the entire Soudano-Sahelian region which endures since the beginning of the twentieth century a continuous decrease in precipitation amount. This paper provides a transboundary synthesis using water ( 18O, 2H and 3H) and carbon isotopes ( 13C and 14C) in conjunction with hydrogeological and hydrochemical data. The objectives are to improve the conceptual model of groundwater recharge and flow within this sandstone reservoir, and to assess the changes in the aquifer due to water abstraction and recent climate changes including an insight into Sahelian aquifers palaeorecharge processes. The local meteoric water line for the Bobo-Dioulasso station is proposed: δ 2H = 8.0 (±0.5)δ 18O + 10.2 (±2.1). Two main tendencies can be derived from groundwater chemistry. First, a slight evolution from the Ca-Mg-HCO 3 type towards a Na-K-HCO 3 type that indicates developed interactions between groundwater and clay minerals related to the residence time of groundwater. A second tendency towards Cl-NO 3-SO 4-HCO 3 water types indicates the anthropogenic influence on groundwater related to the poor sanitary conditions observed around wells. The carbon-14 activity measured on the TDIC varies between 0.3 and 122 pmC, so our record contains samples covering a wide period from Actual to Pleistocene suggesting a continuous recharge of the system through time even if the Sahel region has endured many different climate phases which have influenced the infiltration and recharge processes. All groundwater samples have stable isotope compositions in the range of the present day regional and global meteoric water line

    Knowledge of climate variability is relevant and challenging for farmers, decision makers and population in general. Ninety percent of Burkina Faso active population is engaged in agriculture and livestock, which accounts for 39% of gross domestic product. Located between the coordinates 1o15'-1o55' West and 12o17'- 12o50'North, Massili basin includes Ouagadougou the capital and has four dams, of which the most important dam, Loumbila is used for the capital water supply and irrigation. A change of climate may affect the water resources most likely limit the access to safe water. In order to characterize Massili basin climate variability, daily temperature and precipitation over 1960 to 2012 was analyzed using long-term records from the Ouagadougou synoptic station. By applying R-climdex and instat tools, indices were calculated by a consistent approach recommended by the World Meteorological Organization Expert Team on Climate Change Detection and Indices. The precipitation parameters computed were: the maximum 5-day precipitationamount; the number of days with precipitation amount ≥50 mm ; the maximum precipitation amount in consecutive wet days with RR≥ 1mm; the consecutives dry days;the extremely wet days ; the extreme precipitation in one day, the total precipitation in wet days; the temperature indices computed were : the maximum of the maximum daily temperature, the minimum of daily maximum temperature,the minimum of daily minimum temperature,the cold spell duration indices and the warm spell duration indicator. Results show a slight increase of the maximum 5-day precipitation, maximum precipitation amount in consecutive wet days with RR≥1mm, the onset delayed and the cessation is earlier meaning that the rainfall period is shortening. The total precipitationwas decreased in the basin but there is a slight increase in the occurrence of extremely wet days. CSDI is decreasing while warm spell duration indices are increasing.

    Competition in mosquito larvae is common and different ecological context could change competitive advantage between species. Here, larval competition between the widely sympatric African malaria mosquitoes, Anopheles coluzzii and Anopheles gambiae were investigated in controlled insectary conditions using individuals from laboratory colonies and under ambient conditions using wild mosquitoes in a semi-field enclosure in western Burkina Faso. Larvae of both species were reared in trays at the same larval density and under the same feeding regimen in either single-species or mixed-species populations at varying species ratios reflecting 0, 25, 50 and 75% of competitor species. In the insectaries, where environmental variations are controlled, larvae of the An. coluzzii colony developed faster and with lower mortality than larvae of the An. gambiae colony (8.8±0.1 days and 21±3% mortality vs. 9.5±0.1 days and 32±3% mortality, respectively). Although there was no significant effect of competition on these phenotypic traits in any species, there was a significant trend for higher fitness of the An. coluzzii colony when competing with An. gambiae under laboratory conditions (i.e., lower development time and increased wing length at emergence, Cuzik’s tests, P<0.05). In semi-field experiments, competition affected the life history traits of both species in a different way. Larvae of An. gambiae tended to reduce development time when in competition with An. coluzzii (Cuzick’s test, P=0.002) with no impact either on mortality or size at emergence. On the other hand, An. coluzzii showed a significant trend for reduced larval mortality with increasing competition pressure (Cuzick’s test, P=0.037) and production of smaller females when grown together with An. gambiae (Cuzick’s test, P=0.002). Our results hence revealed that competitive interactions between larvae of the two species are context dependent. They further call for caution when exploring ecological

    Introduction The scale-up of highly active antiretroviral therapy (HAART) has led to a significant improvement in survival of the HIV-positive patient but its effects on health-related quality of life (HRQOL) are less known and context-dependent. Our aim was to assess the temporal changes and factors associated with HRQOL among HIV-positive adults initiating HAART in Burkina Faso. Methods HIV-positive people initiating HAART were prospectively included and followed over a one-year period in three HIV clinics of Ouagadougou. HRQOL was assessed at baseline and at each follow-up visit using physical (PHS) and mental (MHS) summary scores derived from the Medical Outcome Study 36-Item short-form health survey (MOS SF-36) questionnaire. Toxicity related to HAART modification and self-reported symptoms were recorded during follow-up visits. Determinants associated with baseline and changes in both scores over a one-year period were assessed using a mixed linear model. Results A total of 344 patients were included. Their median age at baseline was 37 years [interquartile range (IQR) 30–44] and their median CD4 count was 181 cells/mm3 (IQR 97–269). The mean [standard deviation (SD)] PHS score increased from 45.4 (11.1) at baseline to 60.0 (3.1) at 12 months (p<10−4) and the mean (SD) MHS score from 42.2 (8.7) to 43.9 (3.4) (p<10−2). After one year of treatment, patients that experienced on average two symptoms during follow-up presented with significantly lower PHS (63.9) and MHS (43.8) scores compared to patients that presented no symptoms with PHS and MHS of 68.2 (p<10−4) and 45.3 (p<10−3), respectively. Discussion The use of HAART was associated with a significant increase in both physical and mental aspects of the HRQOL over a 12-month period in this urban African population. Perceived symptoms experienced during follow-up visits were associated with a significant impairment in HRQOL. The appropriate and timely management of reported symptoms during the

    This study investigates the impacts of land use change on water resources in the Dano catchment, Burkina Faso, using a physically based hydrological simulation model and land use scenarios. Land use dynamic in the catchment was assessed through the analysis of four land use maps corresponding to the land use status in 1990, 2000, 2007 and 2013. A reclassification procedure of the maps permitted to assess the major land use changes in the catchment from 1990 to 2013. The land use maps were used to build five land use scenarios corresponding to different levels of land use change in the catchment. Water balance was simulated by applying the Water flow and balance Simulation Model (WaSiM) using observed discharge, soil moisture, and groundwater level for model calibration and validation. Model statistical quality measures (R2, NSE and KGE) achieved during the calibration and the validation ranged between 0.9 and 0.6 for total discharge, soil moisture, and groundwater level, indicating satisfying to good agreements between observed and simulated variables. After a successful multi-criteria validation the model was run with the land use scenarios. The land use assessment exhibited a decrease of savannah at an annual rate of 2% since 1990. Conversely, cropland and urban areas have increased. Since urban areas occupy only 3% of the catchment in 2013 it can be assumed that savannah was mainly converted to cropland. The increase in cropland area results from the population growth and the farming system in the catchment. A clear increase in total discharge (+17%) and decrease in evapotranspiration (-5%) was observed following land use change in the catchment. A strong relationship was established between savannah degradation, cropland expansion, discharge increase and reduction of evapotranspiration. The increase in total discharge is related to high discharge and peak flow, suggesting (i) an increase in water resources that is not available for plant growth and the

    HIV/AIDS is a leading cause of death in most of sub-Saharan countries. HIV/AIDS impact on the quality of life of persons living with HIV in Burkina Faso hasn't been well documented. The aim of the study was to assess the quality of life in persons living with HIV and its associated factors. A cross-sectional study was conducted in Ouagadougou. 424 persons living with HIV were included in the study according to their status with regard to Highly Active Anti Retroviral Treatment: 115 were not yet under treatment, 21 started the treatment within the three months preceding the enrolment and 288 were under treatment for at least 12 months. The quality of life was assessed through the WHOQOL HIV-BREF. Statistical comparisons were made using Mann Whitney U test, Kruskal-Wallis H test, Pearson's khi2 or Fisher's exact test. Correlations were appreciated using Spearman's rho. Logistic regression was used to examine associations between the quality of life scores and sociodemographic or clinical variables. The mean global score of quality of life in all patients was 82.4. Better scores were recorded in the spiritual domain and worst scores in the environmental domain. Men had a higher global score than women (p < 0.001). Illiteracy was significantly associated with a lower quality of life (p = 0.001). Patients having support for medical treatment had a significantly better quality of life (p < 0.01). In multivariate analysis, being a man, having a support for medical care, getting older and self-perceived as healthy, were associated with a global score of quality of life higher than 77, that corresponds to the mid-range of the score in our data. These findings suggest the importance of the socio-psychological support and of a good environment in order to improve the quality of life of people living with HIV, especially in women, in younger and in those having no support for medical care. In the environmental domain, actions of HIV services providers should focus on better

    Meningococcal meningitis remains a periodical threat in the African meningitis belt. The countries concerned, such as Burkina Faso, provided guidelines for its surveillance, diagnosis, treatment, and prevention during outbreaks. The objective of this study is to assess the quality of the surveillance system and case management during an outbreak in Fada N'Gourma district. A retrospective study of the meningitis outbreak in 2007 was conducted by literature review and interviews of health caretakers across 27 health centers (CSPS) and three units in the regional hospital in the district.We reported all data available about surveillance and case management, and then we compared it with the guidelines of the Ministry of Health. The case definition and notification forms were available in all centers and units. During the outbreak, 861 cases were recorded, but only 89% was notified at the upper level and 87% of notification forms were available. The age is marked on all the forms, while the interval between the onset of symptoms and consultation is noted only in 90.7%. The forms were distributed weekly at the district level. Cerebrospinal fluid (CSF) Gram coloration was performed for a limited number of cases (150/349 samples, 42.9%); it showed Gram-negative diplococcus in 86%. Culture was performed for a limited number of patients (7 cases). According to the results of a central level laboratory study, the outbreak was due to Group A Neisseria meningitidis. The case management guidelines were available in all the centers and units which were supervised during the outbreak. Anti-biotherapy was appropriate in 93.6% of the cases. A shortage of antibiotics (free prepositioning) was observed in 7 centers (23.3%). The mortality rate was 3.5%. This assessment shows an under-notification of cases, despite the existence of a surveillance system and supervision, a weak laboratory contribution in germ identification, appropriate case management, and shortage of antibiotics during

  3. Does enrollment status in community-based insurance lead to poorer quality of care? Evidence from Burkina Faso

    2013-01-01

    Introduction In 2004, a community-based health insurance (CBI) scheme was introduced in Nouna health district, Burkina Faso, with the objective of improving financial access to high quality health services. We investigate the role of CBI enrollment in the quality of care provided at primary-care facilities in Nouna district, and measure differences in objective and perceived quality of care and patient satisfaction between enrolled and non-enrolled populations who visit the facilities. Methods We interviewed a systematic random sample of 398 patients after their visit to one of the thirteen primary-care facilities contracted with the scheme; 34% (n = 135) of the patients were currently enrolled in the CBI scheme. We assessed objective quality of care as consultation, diagnostic and counselling tasks performed by providers during outpatient visits, perceived quality of care as patient evaluations of the structures and processes of service delivery, and overall patient satisfaction. Two-sample t-tests were performed for group comparison and ordinal logistic regression (OLR) analysis was used to estimate the association between CBI enrollment and overall patient satisfaction. Results Objective quality of care evaluations show that CBI enrollees received substantially less comprehensive care for outpatient services than non-enrollees. In contrast, CBI enrollment was positively associated with overall patient satisfaction (aOR = 1.51, p = 0.014), controlling for potential confounders such as patient socio-economic status, illness symptoms, history of illness and characteristics of care received. Conclusions CBI patients perceived better quality of care, while objectively receiving worse quality of care, compared to patients who were not enrolled in CBI. Systematic differences in quality of care expectations between CBI enrollees and non-enrollees may explain this finding. One factor influencing quality of care may be the type of provider payment used by the CBI

    Background Burkina Faso is endemic with soil-transmitted helminth infections. Over a decade of preventive chemotherapy has been implemented through annual lymphatic filariasis (LF) mass drug administration (MDA) for population aged five years and over, biennial treatment of school age children with albendazole together with schistosomiasis MDA and biannual treatment of pre-school age children through Child Health Days. Assessments were conducted to evaluate the current situation and to determine the treatment strategy for the future. Methodology/Principal Findings A cross-sectional assessment was conducted in 22 sentinel sites across the country in 2013. In total, 3,514 school age children (1,748 boys and 1,766 girls) were examined by the Kato-Katz method. Overall, soil-transmitted helminth prevalence was 1.3% (95% CI: 1.0–1.8%) in children examined. Hookworm was the main species detected, with prevalence of 1.2% (95% CI: 0.9–1.6%) and mean egg counts of 2.1 epg (95% CI: 0–4.2 epg). Among regions, the Centre Ouest region had the highest hookworm prevalence of 3.4% (95% CI: 1.9–6.1%) and mean egg counts of 14.9 epg (95% CI: 3.3–26.6 epg). A separate assessment was conducted in the Centre Nord region in 2014 using community-based cluster survey design during an LF transmission assessment survey (TAS). In this assessment, 351 children aged 6–7 years and 345 children aged 10–14 years were examined, with two cases (0.6% (95% CI: 0.2–2.1%)) and seven cases (2.0% (95% CI: 1.0–4.1%)) of hookworm infection was identified respectively. The results using both age groups categorized the region to be 2% to <10% in STH prevalence according to the pre-defined cut-off values. Conclusions/Significance Through large-scale preventive chemotherapy, Burkina Faso has effectively controlled STH in school age children in the country. Research should be conducted on future strategies to consolidate the gain and to interrupt STH transmission in Burkina Faso. It is also

    2011-01-01

    Background Systems to exempt the indigent from user fees have been put in place to prevent the worst-off from being excluded from health care services for lack of funds. Yet the implementation of these mechanisms is as rare as the operational research on this topic. This article analyzes an action research project aimed at finding an appropriate solution to make health care accessible to the indigent in a rural district of Burkina Faso. Research This action research project was initiated in 2007 to study the feasibility and effectiveness of a community-based, participative and financially sustainable process for exempting the indigent from user fees. A interdisciplinary team of researchers from Burkina Faso and Canada was mobilized to document this action research project. Results and knowledge sharing The action process was very well received. Indigent selection was effective and strengthened local solidarity, but coverage was reduced by the lack of local financial resources. Furthermore, the indigent have many other needs that cannot be addressed by exemption from user fees. Several knowledge transfer strategies were implemented to share research findings with residents and with local and national decision-makers. Partnership achievements and difficulties Using a mixed and interdisciplinary research approach was critical to grasping the complexity of this community-based process. The adoption of the process and the partnership with local decision-makers were very effective. Therefore, at the instigation of an NGO, four other districts in Burkina Faso and Niger reproduced this experiment. However, national decision-makers showed no interest in this action and still seem unconcerned about finding solutions that promote access to health care for the indigent. Lessons learned The lessons learned with regard to knowledge transfer and partnerships between researchers and associated decision-makers are: i) involve potential users of the research results from the

    This study assesses the potential impact of climate change on water resources in the Dano catchment (Burkina Faso, West Africa). There is now essential consensus on the importance of performing multi (climate)-model assessments in order to estimate the response of the West African climate to global change. Taking advantage of the results of the COordinated Regional climate Downscaling Experiment (CORDEX-Africa) project, this study evaluates climate change impacts on water resources using an ensemble of six Regional Climate Models (RCMs) in a catchment that is potentially vulnerable to climate change and presents a low adaptive capacity. The ensemble of RCMs was first evaluated to get an estimate of the historical simulated rainfall for the catchment by comparing RCM-based simulated historical rainfall to the observed rainfall data provided by the National Meteorological Service (DGM). In general, the simulated historical rainfall agrees within some degree of variability with the observed rainfall in regard to the mean annual cycle of precipitation. However, significant biases such as a double-peaked rainy season as well as the timing of the rainy season were exhibited by individual RCMs. A statistical bias correction (Quantile mapping) was then applied to the RCM-based simulated daily rainfall for the overlapping period of 1971-2000. The results confirm the effectiveness of the applied bias correction method for rainfall. Temperature and bias corrected rainfall data from the ensemble of RCMs was used as input for the Water flow and balance Simulation Model (WaSiM) to simulate river discharge, soil moisture, evapotranspiration and groundwater depth. To take into account the concern of the potential alteration of the climate change signal due to bias correction, uncorrected climate data for a single RCM was also applied to the hydrological model. The simulated hydrological variables show a similar behavior under observed and bias corrected climate data for the

    The goal of this study is to contribute to a better knowledge of certain species providing Non Woody Forest Products (NWFP) in the Centre East of Burkina Faso. This study aims to determine the state of the resources in Vitellaria paradoxa, Balanites aegyptiaca, Tamarindus indica and Lannea microcarpa. For this purpose, an inventory of the vegetation was carried out in circular pieces of land of 1250 m2, as a sample of the zone of work, based on the chart of occupation of the grounds. We are identified 158 species comprising 90 genera and 47 families. Those species represent more than 90% of the trees from which various parts are used in food, traditional pharmacopeia and the craft industry. We also showed that because of the strong anthropisation of the zone, the bad pedoclimatic conditions and the permanent bush fires, the regeneration and growth of Vitellaria paradoxa, Balanites aegyptiaca, Tamarindus indica and Lannea microcarpa are disturbed.

    The present paper investigates the occurrence, removal, and accumulation of protozoan cysts and helminth eggs in a large anaerobic pond treating municipal wastewater of Ouagadougou (Burkina Faso). With a hydraulic retention time of 6.5 days, the anaerobic pond achieved 100% removal of helminth eggs and protozoan cysts most of the time, except during the hot period. The average residual concentrations of helminth eggs and protozoan cysts in the effluent were respectively 0.45 eggs/L (minimum 0 and maximum 3), and 5.4 cysts/L (minimum 0 and maximum 26). Protozoan cysts accumulation in sludge averaged 1,613 cysts/g total solids. Ancylostoma duodenale, Ascaris lumbricoides and Hymenolepis nana were the main helminth species found in the sludge. After 7 years of operation, the sludge in the pond still contained a high level of viable helminth eggs evaluated at 42%.

    The objectives of the present study were to investigate the rate of S.aureus nasal carriage and molecular characteristics in hospital and community settings in Bobo Dioulasso, Burkina Faso. Nasal samples (n = 219) were collected from 116 healthy volunteers and 103 hospitalized patients in July and August 2014. Samples were first screened using CHROMagar Staph aureus chromogenic agar plates, and S. aureus strains were identified by mass spectrometry. Antibiotic susceptibility was tested using the disk diffusion method on Müller-Hinton agar. All S. aureus isolates were genotyped using DNA microarray. Overall, the rate of S. aureus nasal carriage was 32.9% (72/219) with 29% in healthy volunteers and 37% in hospital patients. Among the S. aureus isolates, only four methicillin-resistant S. aureus (MRSA) strains were identified and all in hospital patients (3.9%). The 72 S. aureus isolates from nasal samples belonged to 16 different clonal complexes, particularly to CC 152-MSSA (22 clones) and CC1-MSSA (nine clones). Two clones were significantly associated with community settings: CC1-MSSA and CC45-MSSA. The MRSA strains belonged to the ST88-MRSA-IV or the CC8-MRSA-V complex. A very high prevalence of toxinogenic strains 52.2% (36/69), containing Panton-Valentine leucocidin- and EDIN-encoding genes, was identified among the S. aureus isolates in community and hospital settings. This study provides the first characterization of S. aureus clones and their genetic characteristics in Burkina Faso. Altogether, it highlights the low prevalence of antimicrobial resistance, high diversity of methicillin-sensitive S. aureus clones and high frequency of toxinogenic S. aureus strains. PMID:27679613

    The G-6-PD deficiency has an important polymorphism with genotypic variants such as 202A/376G, 376G/542T and 376G/968T known in West African populations. It would confer protection against severe forms of malaria although there are differences between the various associations in different studies. In this study we genotyped six (06) variants of the G-6-PD gene in people with symptomatic malaria in urban areas in Burkina Faso. One hundred and eighty-two (182) patients who tested positive using rapid detection test and microscopy were included in this study. A regular PCR with the GENESPARK G6PD African kit was run followed by electrophoresis, allowing initially to genotype six SNPs (G202A, A376G, A542T, G680T, C563T and T968C). Women carrying the mutations 202A and/or 376G were further typed by real-time PCR using TaqMan probes rs1050828 and rs1050829. In the study population the G-6-PD deficiency prevalence was 9.9%. In addition of G-6-PD A- (202A/376G) variant, 376G/542T and 376G/968T variants were also detected. Hemoglobin electrophoresis revealed that 22.5% (41/182) of the individuals had HbAC compared with2.2% with HbAS and one individual had double heterozygous HbSC. There was no correlation between the G-6-PD deficiency or haemoglobinopathies and symptomatic malaria infections in this study. Our study confirms that the G-6-PD deficiency does not confer protection against Plasmodium falciparum infections. As opposed to previous genotyping studies carried out in Burkina Faso, this study shows for the first time the presence of the variant A- (376G/968C) and warrants further investigation at the national level and in specific ethnic groups.

    The performance of indirect haemagglutination assays (IHA), enzyme-linked immunosorbent assays (ELISA) and indirect immunofluorescent antibody tests (IFAT) were compared with 450 sera from a Schistosoma mansoni-endemic area in Burkina Faso. All participants in this survey provided at least one sample each of stool, urine and serum. From those with an egg-negative Kato-Katz thick smear, a second stool sample was examined. IHA was based on either extracts of adult S. mansoni worms (SmIHA) or S. japonicum egg antigen (SjIHA). For ELISA, three antigen preparations were used, namely: (i) soluble S. mansoni adult worm antigens (SWAP); (ii) soluble S. mansoni egg antigens (SEA); and (iii) a cationic exchange fraction of S. mansoni eggs (CEF6). IFAT was performed with S. mansoni male worm sections. Among the egg-excretors, the sensitivity of ELISA was high and egg antigens performed slightly better (SEA, 96%; CEF6, 97%) than worm antigen (94%). Sensitivity of IHA was satisfactory with homologous (Sm, >85%), but not heterologous (Sj, 56%) parasite antigen. In IFAT, the parenchyma-associated fluorescence showed high sensitivity (95%), but gut-associated fluorescence, which is known to be a sensitive diagnostic marker for schistosome-infected European travelers, was observed only in 76% of a sub-sample of 100 of the endemic sera. Among sera from egg-negative individuals, many gave positive reactions in several or all of the tests employed. These reactions (formally "false positive") are considered to represent true infections, since chemotherapy had not yet been delivered to this population. For the purpose of further surveys in Burkina Faso or other resource-poor settings, we suggest IHA as an accurate diagnostic test and propose to further improve its performance by including egg rather than worm antigens.

    Background Healthcare user fees present an important barrier for accessing services for the poorest (indigents) in Burkina Faso and selective removal of fees has been incorporated in national healthcare planning. However, establishing fair, effective and sustainable mechanisms for the removal of user fees presents important challenges. A participatory action-research project was conducted in Ouargaye, Burkina Faso, to test mechanisms for identifying those who are indigents, and funding and implementing user fee removal. In this paper, we explore stakeholder perceptions of ethical considerations relating to participation and partnership arising in the action-research. Methods We conducted 39 in-depth interviews to examine ethical issues associated with the action-research. Respondents included 14 individuals identified as indigent through the community selection process, seven members of village selection committees, six local healthcare professionals, five members of the management committees of local health clinics, five members of the research team, and four regional or national policy-makers. Using constant comparative techniques, we carried out an inductive thematic analysis of the collected data. Results The Ouargaye project involved a participatory model, included both implementation and research components, and focused on a vulnerable group within small, rural communities. Stakeholder perceptions and experiences relating to the participatory approach and reliance on multiple partnerships in the project were associated with a range of ethical considerations related to 1) seeking common ground through communication and collaboration, 2) community participation and risk of stigmatization, 3) impacts of local funding of the user fee removal, 4) efforts to promote fairness in the selection of the indigents, and 5) power relations and the development of partnerships.

(Malvaceae) are traditionally used in Burkina Faso to treat several ailments, mainly pains, including abdominal infections and associated diseases. Despite the extensive use of these plants in traditional health care, literature provides little information regarding their toxicity and the pharmacology. This work was therefore designed to investigate the toxicological effects of aqueous acetone extracts of Sida acuta Burn f. and Sida cordifolia L. Furthermore, their analgesic capacity was assessed, in order to assess the efficiency of the traditional use of these two medicinal plants from Burkina Faso. Method For acute toxicity test, mice were injected different doses of each extract by intraperitoneal route and the LD50 values were determined. For the subchronic toxicity evaluation, Wistar albinos rats were treated by gavage during 28 days at different doses of aqueous acetone extracts and then haematological and biochemical parameters were determined. The analgesic effect was evaluated in mice by the acetic-acid writhing test and by the formalin test. Results For the acute toxicity test, the LD50 values of 3.2 g/kg and 3.4 g/kg respectively for S. acuta Burn f. and S. cordifolia L. were obtained. Concerning the haematological and biochemical parameters, data varied widely (increase or decrease) according to dose of extracts and weight of rats and did not show clinical correlations. The extracts have produced significant analgesic effects by the acetic acid writhing test and by the hot plate method (p <0.05) and a dose-dependent inhibition was observed. Conclusion The overall results of this study may justify the traditional uses of S. acuta and S. cordifolia . PMID:22883637

    The objectives of the present study were to investigate the rate of S.aureus nasal carriage and molecular characteristics in hospital and community settings in Bobo Dioulasso, Burkina Faso. Nasal samples (n = 219) were collected from 116 healthy volunteers and 103 hospitalized patients in July and August 2014. Samples were first screened using CHROMagar Staph aureus chromogenic agar plates, and S. aureus strains were identified by mass spectrometry. Antibiotic susceptibility was tested using the disk diffusion method on Müller-Hinton agar. All S. aureus isolates were genotyped using DNA microarray. Overall, the rate of S. aureus nasal carriage was 32.9% (72/219) with 29% in healthy volunteers and 37% in hospital patients. Among the S. aureus isolates, only four methicillin-resistant S. aureus (MRSA) strains were identified and all in hospital patients (3.9%). The 72 S. aureus isolates from nasal samples belonged to 16 different clonal complexes, particularly to CC 152-MSSA (22 clones) and CC1-MSSA (nine clones). Two clones were significantly associated with community settings: CC1-MSSA and CC45-MSSA. The MRSA strains belonged to the ST88-MRSA-IV or the CC8-MRSA-V complex. A very high prevalence of toxinogenic strains 52.2% (36/69), containing Panton-Valentine leucocidin- and EDIN-encoding genes, was identified among the S. aureus isolates in community and hospital settings. This study provides the first characterization of S. aureus clones and their genetic characteristics in Burkina Faso. Altogether, it highlights the low prevalence of antimicrobial resistance, high diversity of methicillin-sensitive S. aureus clones and high frequency of toxinogenic S. aureus strains.

    The development of cervical cancer is associated with high-risk Human papilloma viruses (HPV-HR). In sub-Saharan Africa cervical cancer is the most common cancer among women and the leading cause of death attributed to malignant tumors. This study aims to identify HPV genotypes within the 30′S and 50′S HPV families found in two previous studies from our laboratory, and to determine the prevalence of twelve HPV-HR genotypes in a population of women in Ouagadougou. The twelve HPV-HR genotypes were determined by real-time multiplex PCR, in 180 samples from the general population and among a group of HIV-1 infected women. The most common genotypes found were HPV-35 (29.4%) and HPV-31 (26.1%) of the 30′S family, and HPV-52 (29.4%) and HPV-58 (20.6%) of the 50′S family. Multiple infections of HPV-HR were observed in 78.03% of infected women. The frequencies of HPV genotypes from the 30′S and 50′S families were higher, while the genotypes HPV-16 and18 were lower among the women in our study. PMID:24106609

    The impact of a Computerized Immunization Register (CIR) on Expanded Program on Immunization (EPI), with sending SMS to parents before immunization sessions, has never been studied in sub-Saharan Africa. The objective of this study is to measure EPI quickness and completeness of vaccinations after sending call-back SMS to parents through CIR put in place in a health center. In a health center, chosen at random (Colma 1) in the city of Bobo Dioulasso, Burkina Faso, West Africa, mothers, at first EPI session, if they had a mobile phone available at hand or in her surrounding, were randomized for receiving, or not, a call-back SMS before following EPI sessions, after child registration on a Francophone CIR (Siloxane's Intervax ©). Mothers, which were sent SMS and did not correctly followed sessions were asked through mobile phone why their child was late for EPI. 523 newborns were included in the study, with 253 whose parents were sent SMS, and 268 being informed of sessions only by ordinary methods. At second EPI session at 2 months of age, there was a statistical significant increase of coverage for children whose parents received SMS (p<0.001). Quickness to come also to this session was significantly shorter when parents received SMS (p=0.03). At third EPI session at 3 months of age, attendance to EPI for children whose parents were sent SMS was significantly better (p<0.001). Quickness to come to this session was shorter for children with SMS (p=0.02). At fourth EPI session at 4 months of age, attendance for children with SMS was significantly better for children whose parents were sent SMS (p<0.001). Quickness to come to this session was better but not significantly different (p=0.49). Out of 101 children registered as late for EPI sessions in Colma 1 CIR, even with call-back SMS, 19 (19%) parents could not be reached on the telephone. 31/82 (38%) mothers had shifted for EPI to a more proximate vaccination center (Colma 2), and 5 (6%) to private or civil

    Desertification is regarded as one of the major global environmental problems of the 21st century. The African sub-Sahara is often quoted as the most seriously affected region with a significant loss of biological and economic productivity of the land due to climate characteristics and fluctuations, unsustainable land uses, overgrazing and inappropriate agricultural practices. Due to its complexity, dynamism and extent, desertification is complicated to check and assess. The absence of an agreed methodology for the identification of affected areas is a critical point in desertification monitoring and assessment. An integrated approach which uses both qualitative and quantitative measures is crucial to reach the aim of sustainable resource use and has to be reflected in application of sets of indicators. The selection of appropriate indicators and their integration and interpretation should be conducted by the objectives to be achieved and the questions to be answered. This study, carried out within the FP7-ENV-2010 CLUVA project (Climate change and Urban Vulnerability in Africa), aimed to assess the sensitivity to desertification in peri-urban areas of both Ouagadougou (Burkina Faso) and Saint Louis (Senegal) cities. The approach was based on the implementation and adaptation to the local conditions of the modeling methodology developed within the MEDALUS project (Mediterranean Desertification And Land Use). The model is characterized by a multi-factor approach based on the assessment of both environmental quality indicators (vegetation, soil, climate) and anthropogenic factors (land management). All local data, arranged in a GIS environment, allowed the generation of maps identifying Environmentally Sensitive Areas (ESAs) and an Index of Environmentally Sensitive Areas (ESAI). Changes and integrations to the original methodology have been set taking into account the environmental and social features of the whole sub-Saharan west Africa in order to allow the use of

    This paper focuses on changes in vitamin A (VA) intakes as part of the evaluation of a pilot project on social marketing of red palm oil (RPO) as a VA supplement for mothers and children in central-north Burkina Faso. The objectives of the 30-month project are to demonstrate the feasibility and effectiveness of introducing RPO in non-consuming areas. RPO is collected from women in the South-West region and it is sold in project sites by village volunteers. RPO is promoted by community workers trained in persuasive communication and social marketing. The target population is free to buy and consume RPO. Evaluation design includes data collected at onset, then 12 and 24 months later, from the same sample of 210 mothers and their children randomly selected in seven project sites. Children were 1 to 3 years old at onset. Blood samples were collected at baseline from mothers and children for serum retinol determination by HPLC. VA intakes are estimated by a semi-quantitative food frequency questionnaire, using the conventional beta-carotene to retinol conversion factors and the newly revised lower factors. VA deficiency is a major public health problem in the area: 64% of mothers and 85% of children had serum retinol concentrations < 0,70 mumol/l at baseline. VA came mainly from plant foods, particularly fruits and dark green vegetables which provided more than 90% of the dietary VA at onset of the project. Mean vitamin A intakes are low. We found 138 106 mug ER for the children and 302 +/- 235 microg ER for the mothers with conventional factors and 64 +/- 58 microg ER and 133 +/- 162 microg ER, respectively, with the revised factors. One year later, one third of respondents had consumed RPO in the previous week, and it supplied around 56% of the VA intake of children and 67% of mothers (36% and 46% respectively for the whole group). VA intakes were significantly increased at 510 +/- 493 microg ER and 801 +/- 913 microg ER for the children and their mothers respectively

    Résumé La politique actuelle de lutte contre le sida qui repose sur l’extension de l’accès aux traitements et à la prévention exige qu’une proportion élevée de la population connaisse son statut en matière de VIH. Pour cela, l’OMS a proposé le développement de stratégies communautaires délivrant le dépistage et le conseil au-delà des services de soins, comme le test à domicile ou les campagnes de sensibilisation et dépistage de grande envergure, appliqués en Afrique australe et de l’Est. Pour définir les stratégies pertinentes dans des régions de basse prévalence comme l’Afrique de l’Ouest, les expériences communautaires de promotion du dépistage doivent y être évaluées. Cet article présente une évaluation des campagnes au Burkina Faso du point de vue des usagers. Dans le cadre d’un projet sur les pratiques et l’éthique du dépistage dans quatre pays africains (MATCH), une enquête qualitative spécifique a été menée pendant la campagne de 2008, auprès de personnes ayant fait le test pendant la campagne, ayant fait le test hors campagne ou n’ayant pas fait le test. Les appréciations sont globalement très favorables aux campagnes, notamment à cause de l’information dispensée, l’accessibilité des sites, la gratuité du test, la qualité des services et l’effet d’entrainement. Les limites ou critiques sont essentiellement liées à l’affluence ou à la crainte de ne pas être soutenu en cas de résultat positif. La démarche de recours au test ne fait plus l’objet de suspicion, au moins pendant la campagne. Cette « normalisation » du recours au test et la mobilisation collective facilitent des pratiques en groupe, ce qui peut rendre difficile de garder son statut VIH secret. L’évaluation des campagnes par les usagers les présente comme une opportunité pour accéder facilement au test et pour communiquer à ce sujet dans divers espaces sociaux à partir des informations délivrées sur le VIH

    A pilot study to test the efficacy of combining an organophosphate-based insecticide paint and pyrethroid-treated Long Lasting Insecticide Treated Nets (LLINs) against pyrethroid-resistant malaria vector mosquitoes was performed in a real village setting in Burkina Faso. Paint Inesfly 5A IGR™, comprised of two organophosphates (OPs) and an Insect Growth Regulator (IGR), was tested in combination with pyrethroid-treated LLINs. Efficacy was assessed in terms of mortality for 12 months using Early Morning Collections of malaria vectors and 30-minute WHO bioassays. Resistance to pyrethroids and OPs was assessed by detecting the frequency of L1014F and L1014S kdr mutations and Ace-1(R)G119S mutation, respectively. Blood meal origin was identified using a direct enzyme-linked immunosorbent assay (ELISA). The combination of Inesfly 5A IGR™ and LLINs was effective in killing 99.9-100% of malaria vector populations for 6 months regardless of the dose and volume treated. After 12 months, mortality rates decreased to 69.5-82.2%. The highest mortality rates observed in houses treated with 2 layers of insecticide paint and a larger volume. WHO bioassays supported these results: mortalities were 98.8-100% for 6 months and decreased after 12 months to 81.7-97.0%. Mortality rates in control houses with LLINs were low. Collected malaria vectors consisted exclusively of Anopheles coluzzii and were resistant to pyrethroids, with a L1014 kdr mutation frequency ranging from 60 to 98% through the study. About 58% of An. coluzzii collected inside houses had bloodfed on non-human animals. Combining Inesfly 5A IGR™ and LLINs yielded a one year killing efficacy against An. coluzzii highly resistant to pyrethroids but susceptible to OPs that exhibited an anthropo-zoophilic behaviour in the study area. The results obtained in a real setting supported previous work performed in experimental huts and underscore the need to study the impact that this novel strategy may have on clinical

    The objective of this study was to evaluate the acceptability of new formulations of six corn-soy blended flours (CSB) and six lipid-based nutrient supplements (LNS) with different quantities of milk and qualities of soy to be used for the treatment of moderate acute malnutrition (MAM). Furthermore, we wanted to explore the acceptability of foods currently used for the prevention and treatment of malnutrition in Burkina Faso to identify possible barriers that could affect the acceptability of the new formulations of supplementary foods. The study was carried out prior to a randomized controlled trial evaluating the effectiveness of these new formulations. The study involved an observed test-meal and a three-day take-home ration of the experimental food supplements to 6- to 30-months-old healthy children, followed by questionnaire-based interviews about the acceptability of these supplements. Interviews and focus group discussions were carried out to explore the acceptability of foods currently used for the prevention and treatment of malnutrition. The results suggest that both LNS and CSB products with different quantities of milk and qualities of soy are equally well accepted among healthy children in rural Burkina Faso based on general appreciation of the supplements and organoleptic properties. All experimental foods received good ratings and there was no significant difference between the foods. However, after the take-home ration, 58% of participants receiving CSB reported having left-overs at the end of the day compared to 37% (n = 33) of the participants receiving LNS (p = 0.004), suggesting that CSB was not as readily consumed as LNS. Yet, both CSB and LNS products were perceived as easy to administer and the frequency of feeding was estimated to be adequate. The study also found that similar foods, used for the prevention and treatment of malnutrition, were well appreciated in the study location. LNS were to a higher degree associated with medicine

    Background Retention in care and adherence to antiretroviral therapy (ART) among people living with human immunodeficiency virus (PLHIV) is a critical challenge in many African countries including Burkina Faso. Delivering text messaging (short message service, SMS) interventions through mobile phones may help facilitate health service delivery and improve patient health. Despite this potential, no evaluations have been delivered for national scale settings to demonstrate the impact of mobile health (mHealth) for PLHIV. Objectives This study aims to test the impact of SMS text messaging reminders for PLHIV in Burkina Faso, who are under ART. The evaluation identifies whether patients who receive SMS text messages are more likely to (1) retain in care (measured as a dichotomous variable), (2) adhere to antiretroviral regimens (measured as the number of doses missed in the past 7 days), and (3) experience slower disease progression (measured with T-lymphocytes cells). The second objective is to assess its effects on the frequency of health center visits, physical and psychosocial health, nutrition and whether the type of message (text vs image) and frequency (weekly vs semiweekly) have differential impacts including the possibility of message fatigue over time. Methods This 24-month, wide-scale intervention implements a randomized controlled trial (RCT) to evaluate the impact of four variants of a mHealth intervention versus a control group. Our sample comprises adult patients (>15 years of age) undergoing antiretroviral therapy with access to mobile phone services. Multivariate regression analysis will be used to analyze the effect of the intervention on the study population. Data collection is done at baseline and three follow-up waves 6, 12, and 24 months after the intervention starts. Results The targeted 3800 patients were recruited between February 2015 and May 2015. But political uncertainty delayed the launch of the intervention until October 2015. Data

    Background The benefits of universal access to voluntary contraception have been widely documented in terms of maternal and newborn survival, women's empowerment, and human capital. Given population dynamics, the choices and opportunities adolescents have in terms of access to sexual and reproductive health information and services could significantly affect the burden of diseases and nations’ human capital. Objectives The objectives of this paper are to assess the patterns and trends of modern contraception use among sexually active adolescents by socio-economic characteristics and by birth spacing and parity; to explore predictors of use of modern contraception in relation to the health system; and to discuss implications of the findings for family planning policy and programmes. Design Data are from the last three Demographic and Health Surveys of Ethiopia, Burkina Faso, and Nigeria. The descriptive analysis focused on sexually active adolescents (15- to 19-year age group), used modern contraception as the dependent variable, and a series of contact points with the health system (antenatal care, institutional delivery, postnatal care, immunisation) as covariates. The multivariate analysis used the same covariates, adjusting for socio-economic variables. Results There are two different groups of sexually active adolescents: those married or in a union with very low use of modern contraception and lower socio-economic status, and those unmarried, among whom nearly 50% are using modern contraception. Younger adolescents have lower modern contraceptive prevalence. There are significant inequality issues in modern contraception use by education, residence, and wealth quintile. However, while there was no significant progress in Burkina Faso and Nigeria, the data in Ethiopia point to a significant and systematic reduction of inequalities. The narrowing of the equity gap was most notable for childbearing adolescents with no education or living in rural areas. In the

    A longitudinal entomological study was carried out from 1999 to 2001 in Lena, a humid savannah village in the western region of Burkina Faso in order to establish malaria vector bionomics and the dynamics of malaria transmission. In the first year, malaria transmission was mainly due to An. gambiae s.s., but during the two later years was due to An. funestus, which were observed in high frequency towards the end of the rainy season. PCR identification of samples of An. gambiae s.1. showed 93% to be An. gambiae s.s. and 7% An. arabiensis. An. funestus constituting more than 60% of the vectors were identified in PCR as An. funestus s.s. The persistence of intense vectorial activity in this village was probably due to the road building in a swampy area creating a semi-permanent swamp that provided large sites for larval mosquitoes. These swampy sites seemed to be more favorable for An. funestus than for An. gambiae s.s. Thus, land development must be monitored and subjected to planning to minimize vector proliferation. Such a system of planning could lead to the restriction or even elimination of the swamp that is the source of larvae developing in the heart of the village. PMID:18697309

    This study focuses on the potential role of technical and institutional innovations for improving water management in a multi-user context in Burkina Faso. We focus on a system centered on three reservoirs that capture the waters of the Upper Comoé River Basin and servicing a diversity of users, including a sugar manufacturing company, a urban water supply utility, a farmer cooperative, and other downstream users. Due to variable and declining rainfall and expanding users' needs, drastic fluctuations in water supply and demand occur during each dry season. A decision support tool was developed through participatory research to enable users to assess the impact of alternative release and diversion schedules on deficits faced by each user. The tool is meant to be applied in the context of consultative planning by a local user committee that has been created by a new national integrated water management policy. We contend that both solid science and good governance are instrumental in realizing efficient and equitable water management and adaptation to climate variability and change. But, while modeling tools and negotiation platforms may assist users in managing climate risk, they also introduce additional uncertainties into the deliberative process. It is therefore imperative to understand how these technological and institutional innovations frame water use issues and decisions to ensure that such framing is consistent with the goals of integrated water resource management.

    Leafy vegetable sauces from Burkina Faso were assessed as a potential vehicle for food fortification. First, iron and zinc bioaccessibility were measured by dialysability method in amaranth and Jew's mallow sauces and in traditional whole dishes consisting of maize paste plus leafy vegetable sauces. Iron dialysability and solubility were higher in amaranth than in Jew's mallow sauce, pointing to a marked effect of the matrix. Iron dialysability was hardly affected by the maize paste contrary to zinc dialysability, which was reduced. Second, iron and zinc bioaccessibility was assessed in the same sauces fortified with NaFeEDTA or iron sulfate. Added iron, i.e. iron supplied by fortification, represented 60% of total iron at the low fortification level and 80% at high level. In amaranth sauces with the high level of fortification using NaFeEDTA and iron sulfate, fractional dialysable iron reached respectively 66% and 26% compared to only 8.1% in the unfortified sauce. Similarly, in Jew's mallow sauces, fractional dialysable iron was 57% and 5% respectively with NaFeEDTA and iron sulfate and less than 1% in the unfortified sauce. Concomitantly, fractional dialysable zinc increased by respectively 20% and 40% in amaranth and Jew's mallow sauces fortified with NaFeEDTA whereas it remained unchanged with iron sulfate. Iron fortification could be an efficient way to greatly increase the available iron content of green leafy vegetable sauces and for this purpose NaFeEDTA is more effective than iron sulfate whatever the food matrix.

    Improved leafy vegetable (LV) sauces, with amaranth, sorrel, and Ceylon spinach/spider plant leaves were formulated from traditional recipes to assess their potential use for food-to-food fortification in iron, zinc and vitamin A in the diet of young children and their mothers in Burkina Faso. Improvement was based on an increase in LV proportion and a decrease in mineral absorption inhibitors. An increase in iron content of up to 3 mg/100 g was obtained in some improved sauces in which dried fish was replaced by chicken liver, and vitamin A content was about 40 times higher than in traditional sauces. Fractional dialyzable iron was low in all sauces. Intakes of sauce were measured to assess their acceptability and no significant difference was found between traditional and improved formulations. The mean intakes of sauces were 66 ± 40 g for young children and 166 ± 65 g for their mothers. Amaranth or Ceylon spinach/spider plant sauces, consumed with the cereal based paste "tô" twice a day, would contribute 80 to 86% of children's estimated average requirement (EAR) of iron and to 90 to 170% of EAR of vitamin A but their contribution to zinc and energy needs would remain low.

    Accumulating evidence indicates that health crises can play a key role in precipitating or exacerbating poverty. For women of reproductive age in low-income countries, the complications of pregnancy are a common cause of acute health crisis, yet investigation of longer-term dynamics set in motion by such events, and their interactions with other aspects of social life, is rare. This article presents findings from longitudinal qualitative research conducted in Burkina Faso over 2004–2010. Guided by an analytic focus on patterns of continuity and change, and drawing on recent discussions on the notion of ‘resilience’, and the concepts of ‘social capital’ and ‘bodily capital’, we explore the trajectories of 16 women in the aftermath of costly acute healthcare episodes. The synthesis of case studies shows that, in conditions of structural inequity and great insecurity, an individual's social capital ebbs and flow over time, resulting in a trajectory of multiple adaptations. Women's capacity to harness or exploit bodily capital in its various forms (beauty, youthfulness, physical strength, fertility) to some extent determines their ability to confront and overcome adversities. With this, they are able to further mobilise social capital without incurring excessive debt, or to access and accumulate significant new social capital. Temporary self-displacement, often to the parental home, is also used as a weapon of negotiation in intra-household conflict and to remind others of the value of one's productive and domestic labour. Conversely, diminished bodily capital due to the physiological impact of an obstetric event or its complications can lead to reduced opportunities, and to further disadvantage. PMID:23063215

    Background We investigated serological correlates of protection against Neisseria meningitidis serogroup A (NmA) in Burkina Faso before the introduction of NmA conjugate vaccine. Methodology/Principal Findings We collected blood from a representative sample (N = 1022) of Bobo-Dioulasso residents. Sera were evaluated for serum bactericidal antibody (SBA) activity against NmA strains of immunotype L11 (F8238) and L10 (3125) and NmA-specific IgG. Seroprevalence was compared to the age-specific NmA meningitis incidence in Bobo-Dioulasso during March 2007–February 2008. Meningococcal carriage was evaluated in a subset (N = 538). Geometric mean titres (GMT)/concentrations (GMC) of SBA and NmA-specific IgG increased with age, peaking around age 20 years. Overall, 70% of our sample had NmA-specific IgG ≥2 ug/mL. Meningitis incidence was highest in those aged <6 months and 5–19 years. No NmA carriers were found. Compared to the reference strain SBA, GMTs were higher against a locally isolated strain and around 40-fold lower against Dutch strain 3125. Conclusions/Significance This study provides estimates of natural immunity to NmA, according to a variety of antibody measures, which will be helpful in ascertaining antibody persistence after MenAfriVac™ introduction. Age-specific seroprevalence of reference strain SBA titres most likely reflects exposure to meningococci and consecutive reactive immunity. We could not define any serological correlate of protection. PMID:23457471

  18. An analysis of timing and frequency of malaria infection during pregnancy in relation to the risk of low birth weight, anaemia and perinatal mortality in Burkina Faso

    2012-01-01

    Background A prospective study aiming at assessing the effect of adding a third dose sulphadoxine-pyrimethamine (SP) to the standard two-dose intermittent preventive treatment for pregnant women was carried out in Hounde, Burkina Faso, between March 2006 and July 2008. Pregnant women were identified as earlier as possible during pregnancy through a network of home visitors, referred to the health facilities for inclusion and followed up until delivery. Methods Study participants were enrolled at antenatal care (ANC) visits and randomized to receive either two or three doses of SP at the appropriate time. Women were visited daily and a blood slide was collected when there was fever (body temperature > 37.5°C) or history of fever. Women were encouraged to attend ANC and deliver in the health centre, where the new-born was examined and weighed. The timing and frequency of malaria infection was analysed in relation to the risk of low birth weight, maternal anaemia and perinatal mortality. Results Data on birth weight and haemoglobin were available for 1,034 women. The incidence of malaria infections was significantly lower in women having received three instead of two doses of SP. Occurrence of first malaria infection during the first or second trimester was associated with a higher risk of low birth weight: incidence rate ratios of 3.56 (p < 0.001) and 1.72 (p = 0.034), respectively. After adjusting for possible confounding factors, the risk remained significantly higher for the infection in the first trimester of pregnancy (adjusted incidence rate ratio = 2.07, p = 0.002). The risk of maternal anaemia and perinatal mortality was not associated with the timing of first malaria infection. Conclusion Malaria infection during first trimester of pregnancy is associated to a higher risk of low birth weight. Women should be encouraged to use long-lasting insecticidal nets before and throughout their pregnancy. PMID:22433778

    We study the geography of schistosomiasis across Burkina Faso by means of a spatially explicit model of water-based disease dynamics. The model quantitatively addresses the geographic stratification of disease burden in a novel framework by explicitly accounting for drivers and controls of the disease, including spatial information on the distributions of population and infrastructure, jointly with a general description of human mobility and climatic/ecological drivers. Spatial patterns of disease are analysed by the extraction and the mapping of suitable eigenvectors of the Jacobian matrix subsuming the stability of the disease-free equilibrium. The relevance of the work lies in the novel mapping of disease burden, a byproduct of the parametrization induced by regional upscaling, by model-guided field validations and in the predictive scenarios allowed by exploiting the range of possible parameters and processes. Human mobility is found to be a primary control at regional scales both for pathogen invasion success and the overall distribution of disease burden. The effects of water resources development highlighted by systematic reviews are accounted for by the average distances of human settlements from water bodies that are habitats for the parasite’s intermediate host. Our results confirm the empirical findings about the role of water resources development on disease spread into regions previously nearly disease-free also by inspection of empirical prevalence patterns. We conclude that while the model still needs refinements based on field and epidemiological evidence, the proposed framework provides a powerful tool for large-scale public health planning and schistosomiasis management.

    The Sahelian countries are increasingly affected by lack of water, soil erosion, desertification and loss of biodiversity. Land and water resources are currently facing an overwhelming pressure due to population growth and to a significant decrease in rainfall rates since the 1970s. Nevertheless, the decrease of the number of rainy days did not affect neither rainfall aggressiveness nor daily rainfall extreme values. Rill and gully erosion, the progressive disappearance of the vegetation and the extension of soil surface crusting result in the reduction of soil thickness, the decrease of nutrients holding capability and water storage loss. To cope with these issues, Soil and Water Conservation (SWC) works have been highly employed in the Sahelian area. However, a proper cost-effectiveness analysis of these interventions at catchment scale requires a quantitative survey on erosion and sedimentation processes, which is expensive and time-consuming. Where data for calibration and validation of process-based models are scarce, a synthetic method to evaluate the economical sustainability of a proposed intervention could be of paramount importance. Referring to a field data collection and to a literature survey, the study herein proposed aims to assess the effectiveness of SWC measures, employed to limit soil erosion and reservoir siltation. Using the Laaba watershed (Northern Burkina Faso, Department of Koumbri) as a case study, the catchment sediment budget is estimated by means of topographical, pedologic and land use parameters and the sedimentation rates of the reservoir and the SWC works. Finally, a cost-effectiveness analysis is performed to assess the economical sustainability of SWC interventions. Although not intended to be quantitative at a local scale, the proposed methodology can be easily implemented for land and water management to prioritize the areas of intervention when data and financial resources are limited, and it is beneficial where the application

    Recent results from the phase 3 trial of RTS,S/AS01 malaria vaccine show that the vaccine induced partial protection against clinical malaria in infants and children; given the high burden of the disease it is currently considered for use in malaria endemic countries. To inform adoption decisions the paper proposes a generalizable methodology to estimate the cost of vaccine introduction using routinely collected and publicly available data from the cMYP, UNICEF, and WHO-CHOICE. Costing is carried out around a set of generic activities, assumptions, and inputs for delivery of immunization services adapted to a given country and deployment modality to capture among other factors the structure of the EPI program, distribution model, geography, and demographics particular to the setting. The methodology is applied to estimate the cost of RTS,S introduction in Burkina Faso, Ghana, Kenya, Senegal, Tanzania, and Uganda. At an assumed vaccine price of $5 per dose and given our assumptions on coverage and deployment strategy, we estimate total economic program costs for a 6-9 months cohort within $23.11-$28.28 per fully vaccinated child across the 6 countries. Net of procurement, costs at country level are substantial; for instance in Tanzania these could add as much as $4.2 million per year or an additional $2.4 per infant depending on the level of spare capacity in the system. Differences in cost of vaccine introduction across countries are primarily driven by differences in cost of labour. Overall estimates generated with the methodology result in costs within the ranges reported for other new vaccines introduced in SSA and capture multiple sources of heterogeneity in costs across countries. Further validation with data from field trials will support use of the methodology while also serving as a validation for cMYP and WHO-CHOICE as resources for costing health interventions in the region.

    Leafy vegetable sauces from Burkina Faso were assessed as a potential vehicle for food fortification. First, iron and zinc bioaccessibility were measured by dialysability method in amaranth and Jew's mallow sauces and in traditional whole dishes consisting of maize paste plus leafy vegetable sauces. Iron dialysability and solubility were higher in amaranth than in Jew's mallow sauce, pointing to a marked effect of the matrix. Iron dialysability was hardly affected by the maize paste contrary to zinc dialysability, which was reduced. Second, iron and zinc bioaccessibility was assessed in the same sauces fortified with NaFeEDTA or iron sulfate. Added iron, i.e. iron supplied by fortification, represented 60% of total iron at the low fortification level and 80% at high level.

De même, le taux d'alphabétisation sans cesse croissant s'accompagne d'une profonde modification des conceptions et des comportements. La présente étude visait à déterminer l′impact des déterminants socioéconomiques sur le processus du recours aux soins par les familles. Méthodes Il s'est agi d'une enquête transversale portant sur 200 familles, menée dans le service de psychiatrie du Centre Hospitalier Universitaire Yalgado Ouédraogo de Ouagadougou. Variable à expliquer: premier recours aux soins par les familles (guérisseur traditionnel ou prières religieuses vs. consultations psychiatrique ou médicale). Variable explicative: catégorie socioprofessionnelle classée en suivant la nomenclature des professions et catégories socioprofessionnelles; niveau d’études. L'analyse statistique a été effectuée à l'aide du logiciel SAS version 9.2. Le test du Khi deux a été utilisé. Résultats Il existait une association entre le choix du premier recours et la Profession et la catégorie socioprofessionnelledu « décideur » (p = 0.0006) ainsi que leniveau d’études du « décideur » (p = 0.0001). Conclusion La Profession et Catégorie Sociale et le niveau d'instruction scolaire pourraient être un marqueur important dans les politiques visant à optimiser les processus de recours aux soins des patients dans le circuit de soins.

    La localisation cutanée de la maladie tuberculeuse demeure une forme rare et représente seulement 2,1% des localisations. L'objet de cette étude est de rapporter le profil épidémiologique, anatomoclinique et évolutif des cas de tuberculose ganglio-cutanée diagnostiqués dans un CHU au Burkina Faso. La fréquence de la tuberculose cutanée est très faible au CHUSS. Six cas ont été diagnostiqués entre 2004 et 2010, soit une fréquence de un cas par an. La durée d’évolution des cas allait de deux jusqu’à dix ans avant leur diagnostic. Les lésions observées étaient: trois scrofulodermes, trois gommes, une tuberculose testiculaire associée à un mal de Pott, un cas de polyadénopathies et des cicatrices atropho-rétractiles dans la plupart des cas. Sur le plan anatomopathologique, des granulomes tuberculoïdes ont été mis en évidence dans tous les cas avec une forte réaction tuberculinique à l'IDR. Sous antituberculeux pendant six mois, l’évolution a été bonne dans tous les cas mais au prix de séquelles cutanées cicatricielles inesthétiques. Son ampleur reste peut-être encore méconnue. Le renforcement du plateau technique du CHU et une bonne collaboration interdisciplinaire contribuerait à un meilleur diagnostic et prise en charge de cette affection. PMID:24648863

    To be useful proxies of micronutrient intake at the population level in resource-limited societies, dietary diversity indicators should be simple and easy to collect in large surveys and their accuracy needs to be assessed. The present study aimed at comparing food group diversity indicators (FGI) derived from simple qualitative list-based questionnaires (qFGI) to the same indicators derived from quantitative 24-h recalls (QFGI). Both methods were administered separately on each of 3 recall days to women in 2 districts of Ouagadougou, Burkina Faso. Data were available for a total of 526 women x recalls. This study was performed within the framework of the Women's Dietary Diversity Project, which sought to analyze the relationships between various QFGI and the mean probability of adequacy (MPA) of women's diets across 11 micronutrients. The comparison between paired qFGI and QFGI scores was made both in terms of accuracy of the reporting by the list-based questionnaire, taking the QFGI as the gold standard, and in terms of performance of indicators in predicting an MPA > 60%. Examination of paired QFGI-qFGI differences revealed that the more disaggregated the FGI, the higher were the mean differences in scores. Food groups most frequently misreported often corresponded to foods put in small quantities in sauces. Overreporting by list-based questionnaires was observed for indicators applying a 15-g minimum quantity of consumption for a group to count in the score and this may result in weaker performance in predicting the MPA. These results highlight trade-offs between accuracy and simplicity when operationalizing FGI through qualitative questionnaires.

    One hundred chicken carcasses purchased from three markets selling poultry in Ouagadougou, Burkina Faso, between June 2010 and October 2010 were examined for their microbiological quality. The presence of Salmonella was investigated using standard bacteriological procedures, and the isolates obtained were serotyped and tested for antimicrobial susceptibility. The presence of virulence-associated genes of the five main pathogroups of diarrheagenic Escherichia coli-Shiga toxin-producing E. coli (STEC), enteropathogenic E. coli (EPEC), enteroaggregative E. coli (EAEC), enterotoxigenic E. coli, and enteroinvasive E. coli-was investigated using 16-plex polymerase chain reaction (PCR) on the mixed bacterial cultures from the poultry samples. Of the 100 chicken carcasses studied, 57 were contaminated by Salmonella; 16 different serotypes were identified, the most frequent being Salmonella Derby, found in 28 samples. Four Salmonella strains were resistant to tetracycline, and two were resistant to streptomycin. Based on the PCR detection of the virulence genes, in total, 45 carcasses were contaminated by three pathogroups of E. coli: STEC, EPEC, or EAEC. The STEC and EPEC virulence genes were detected on six and 39 carcasses, respectively. EAEC virulence genes were only detected in combination with those of EPEC (on 11 carcasses) or STEC (on two carcasses). The STEC-positive carcasses contained the genes stx(1), stx(2), eaeA, escV, and ent in different combinations. None of the EPEC-positive carcasses contained the bfp gene, indicating that only atypical EPEC was present. EAEC virulence genes detected were aggR and/or pic. The high proportion of chicken carcasses contaminated by Salmonella and diarrheagenic E. coli indicates a potential food safety risk for consumers and highlights the necessity of public awareness of these pathogens.

    Improving the use of public maternal health facilities to prevent maternal death is a priority in developing countries. Accumulating evidence suggests that a key factor in choosing a facility-based delivery is the collaboration and the communication between healthcare providers and women. This article attempts to provide a fine-grained understanding of health system deficiencies, healthcare provider practices and women's experiences with maternal public healthcare. This article presents findings from ethnographic research conducted in the Central-East Region of Burkina Faso over a period of eight months (January-August 2013). It is based on monthly interviews with 14 women from village (10) and town (4) and on structured observations of clinical encounters in three primary healthcare facilities (two rural and one urban) (23 days). In addition, 13 health workers were interviewed and 11 focus groups with women from village (6) and town (5) were conducted (48 participants). Guided by an analytic focus on strategies and tactics and drawing on recent discussions on the notion of 'biomedical security', the article explores what tactics women employ in their efforts to maximize their chances of having a positive experience with public maternal healthcare. The synthesis of the cases shows that, in a context of poverty and social insecurity, women employ five tactics: establishing good relations with health workers, being mindful of their 'health booklet', attending prenatal care consultations, minimizing the waiting time at the maternity unit and using traditional medicines. In this way, women strive to achieve biomedical security for themselves and their child and to preserve their social reputation. The study reveals difficulty in the collaboration and communication between health workers and women and suggests that greater attention should be paid to social relations between healthcare providers and users.

    A cross-sectional study was initiated in Burkina Faso’s National Tuberculosis Programme to confirm successful treatment results within 3 months of completing treatment and to characterise longer-term outcomes 12–24 months after completion. The sample (n = 278) included 91 patients who had completed treatment 0–3 months earlier (‘short-term’ sample) and 187 patients who had completed treatment 12–24 months earlier (‘long-term’ sample). All sputum specimens from the short-term sample were confirmed as negative. In the long-term sample, among 154 patients with available information, 13 (8%) had died, 24 were not traced, and 117 (76%) were interviewed and had sputum examinations, of which 2 (2%) were smear-positive. Recording of successful treatment outcomes shows good validity. PMID:26392942

    Introduction L'accroissement rapide de la prévalence du diabète sucré en Afrique subsaharienne constitue un problème de santé public. L'Organisation Mondiale de la Santé (OMS) estime qu’à l'horizon 2025, l'augmentation la plus significative de la prévalence du diabète sera enregistrée dans les pays en développement. Ceux-ci devraient abriter 75% des patients diabétiques du monde. Outre ses complications métaboliques, le diabète est un facteur de risque cardiovasculaire majeur. Le but de notre étude était de decrire le profil épidémiologique du diabète et d’évaluer le niveau de perception de la maladie par une population africaine en milieu urb qwqain de Ouagadougou. Méthodes Le diabète a été défini chez tout sujet ayant une glycémie casuelle supérieure à 2 g/L ou une glycémie à jeun supérieur ou égale à 1,26 g/L (≥ 7 mmol/L) à deux controles d'une semaine d'intervalle. Etaient considérés diabétique, les sujets déjà suivis et ceux nouvellement dépistés par l'etude. Résultats L’étude a inclus 1532 personnes, d’âge compris entre 25 et 64 ans dont 55,6% d'hommes et 44,4% de femmes. L’âge moyen était 36,10 ± 11,19 ans. La tranche d’âge de 25 à 34 ans était la plus représentée avec une proportion de 57,1%. La glycémie moyenne était de 1,04 g/L, la proportion des femmes ayant une hyperglycémie était statistiquement plus importante que celle des hommes (p< 0,05). Près de 81,3% de la population ignoraient que le diabète était un facteur de risque cardiovasculaire. Conclusion Il est urgent de mettre en place un programme national de lutte contre le diabète sucré et les autres maladies non transmissibles au Burkina Faso. PMID:26524982

    Climate changes talks regularly underline that developing countries' agriculture could play a stronger role in GHGs mitigation strategies and benefit from the Kyoto Protocol program of subsidies. Scientists explain that agriculture can contribute to carbon mitigation by storing more carbon in the soil through greener cropping systems. In this context, a growing number of research projects have started to investigate how developing countries agriculture can contribute to these objectives. The clean development mechanism (CDM) proposed in the Kyoto protocol is one particular policy instrument that can incite farmers to mitigate the GHG balance towards more sequestration and less emission. Some economists such as Michael Porter think that environmental regulation lead to a win-win outcome, in which case subsidies are not necessary. If it is a trade-off between incomes and the environment, subsidies are required. CDM can be mobilized to support the mitigation strategy. Agriculture implies the use of inputs. Reducing the emission implies the reduction of those inputs which will in turn imply a yield decrease. The study aims to assess whether this measure will imply a trade-off between environmental and economic objectives or a win-win situation. I apply this study to the case of small farmers in Burkina Faso through environmental instruments such as the emissions limits and agroforestry using a bioeconomic model, in which the farmers maximize their utility subject to constraints. The study finds that the limitation of emissions in annual crops production involves a trade-off. by impacting negatively their net cash come. By integrating perennial crops in the farming system, the farmers' utility increases. Around 6,118 kg are sequestrated individually. By computing the value on this carbon balance, farmers' net cash incomes go better. Then practicing agroforestry is a win-win situation, as they reach a higher level of income, and reduce emissions.

    La démarche pluridisciplinaire s'impose de plus en plus dans le secteur de la santé dans le contexte africain, où les parcours thérapeutiques sont pluriels et les rapports des usagers des centres de santé sont complexes et peu satisfaisants. La compréhension des représentations de la maladie est nécessaire pour offrir des soins appropriés certes, mais l'expérience individuelle des malades représente également une source de savoir. Les données ont été collectées à travers des entretiens semi-directifs, le recueil des récits de vie et des observations participantes. Cet article rend compte d'une expérience d'implication de socio-anthropologue dans la mise en œuvre d'un programme de santé publique au Burkina Faso en vue d'une amélioration de la prise en charge des malades tuberculeux. L'analyse des données à été conduite dans une visée réflexive. Les perspectives socio-anthropologiques ont révélé que l'expérience des anciens malades tuberculeux peut être mise à profit afin d'apporter des changements dans les relations thérapeutiques et l'intégration sociale des autres malades. Cette idée à été mise en application pour tenir lieu d'une traduction des analyses anthropologiques en actes pour un changement. L'article évoque la manière dont l'approche socio-anthropologique au sein d'un programme de santé, peut mettre en évidence le potentiel des malades à être des acteurs importants dans le fonctionnement des services de soins et leur propre bien-être. Dans cette situation, la démarche théorique implique la réflexivité de l'anthropologue, mais également un regard critique sur les modes d'intervention en santé publique. PMID:24009798

    Background: In Burkina Faso, a comprehensive 35-month radio campaign addressed key, multiple family behaviors for improving under-5 child survival and was evaluated using a repeated cross-sectional, cluster randomized design. The primary outcome of the trial was postneonatal under-5 child mortality. This paper reports on behavior change achieved at midline. Method: Fourteen community radio stations in 14 geographic areas were selected based on their high listenership. Seven areas were randomly allocated to receive the intervention while the other 7 areas served as controls. The campaign was launched in March 2012. Cross-sectional surveys of about 5,000 mothers of under-5 children, living in villages close to the radio stations, were conducted at baseline (from December 2011 to February 2012) and at midline (in November 2013), after 20 months of campaigning. Statistical analyses were based on cluster-level summaries using a difference-in-difference (DiD) approach and adjusted for imbalances between arms at baseline. In addition, routine health facility data were analyzed for evidence of changes in health facility utilization. Results: At midline, 75% of women in the intervention arm reported recognizing radio spots from the campaign. There was some evidence of the campaign having positive effects on care seeking for diarrhea (adjusted DiD, 17.5 percentage points; 95% confidence interval [CI], 2.5 to 32.5; P = .03), antibiotic treatment for fast/difficult breathing (adjusted DiD, 29.6 percentage points; 95% CI, 3.5 to 55.7; P = .03), and saving money during pregnancy (adjusted DiD, 12.8 percentage points; 95% CI, 1.4 to 24.2; P = .03). For other target behaviors, there was little or no evidence of an impact of the campaign after adjustment for baseline imbalances and confounding factors. There was weak evidence of a positive correlation between the intensity of broadcasting of messages and reported changes in target behaviors. Routine health facility data

    Les ganglions de la tête et du cou sont parmi les localisations les plus fréquentes de la tuberculose, un problème de santé publique dans le monde. Une étude rétrospective conduite entre 2001 et 2010 rapporte les caractéristiques épidémiologiques et cliniques de l'adénite tuberculeuse de la tête et du cou, au CHU Sanou Souro, au Burkina Faso. Au total, 115 patients ont été observés dont l'âge était compris entre 2 ans et 64 ans (moyenne 31,46 ans). Il y avait 53 patients de sexe masculin (46,1%) et 62 de sexe féminin (53,9%). Un pic de fréquence de 39,8% était observé entre 30 et 39 ans. Les adénopathies cervicales étaient multiples chez 96,5% des patients et abcédées chez 30%. Elles étaient associées à des adénopathies extra cervicales chez 16,6% des patients. Chez 83,4% des patients, il a été noté un ou plusieurs signes à type d'asthénie et ou d'amaigrissement (70,8%), de fièvre 25% ou de toux (20,8%). L'infection associée la plus fréquente était celle par le VIH, observée chez 43,3% des patients. Les résultats de cette étude commandent la recherche systématique de l'infection par le VIH chez tout patient porteur d'adénite cervicale tuberculeuse dans un contexte de double endémicité de la tuberculose et de l'infection à VIH.

    Objectives Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) are common sexually transmitted infections (STI). We assessed the cumulative risk of NG and CT in a cohort of HIV-1-infected high-risk women taking antiretrovirals over 4 years in Burkina Faso. Methods Between March 2007 and February 2011, participants were followed every 3–6 months. At each visit, participants underwent a gynaecological examination with collection of cervical and vaginal swabs. Random-effects logistic regression models were used to analyse associations of NG and CT infection with behavioural and biological factors. Results 172 women had samples tested for NG and CT during the study period, in a total of 1135 visits. NG was detected in 6.4% of women (11/172, 95% CI 2.7 to 10.1) at a rate of 2.76 cases (95% CI 1.53 to 4.99) per 100 person-years. CT was detected in 1.7% (3/172, 95% CI 0 to 3.7) of women at a rate of 0.75 cases (95% CI 0.24 to 2.34) per 100 person-years. The majority of women were asymptomatic (9/14). In the multivariable model, the presence of NG or CT was associated with tobacco use (aOR=11.85, 95% CI 1.13 to 124.17), and concurrent genital HIV-1 RNA shedding (aOR=4.78, 95% CI 1.17 to 19.46). Higher levels of education (aOR=0.17, 95% CI 0.03 to 0.92), and age greater than 35 years (aOR=0.07, 95% CI 0.01 to 0.92) were associated with lower odds of infection. Conclusions The risk of NG or CT infection remains low among high-risk women in Bobo-Dioulasso. This provides some evidence that antiretroviral use does not contribute to behavioural disinhibition. The asymptomatic nature of most infections underscores the need for regular screening and treatment of STIs in core groups. PMID:24337732

    Background Intermittent screening and treatment (IST) of malaria during pregnancy has been proposed as an alternative to intermittent preventive treatment in pregnancy (IPTp), where IPTp is failing due to drug resistance. However, the antenatal parasitaemias are frequently very low, and the most appropriate screening test for IST has not been defined. Methodology/Principal Findings We conducted a multi-center prospective study of 990 HIV-uninfected women attending ANC in two different malaria transmission settings at Tororo District Hospital, eastern Uganda and Colsama Health Center in western Burkina Faso. Women were enrolled in the study in the second or third trimester of pregnancy and followed to delivery, generating 2,597 blood samples for analysis. Screening tests included rapid diagnostic tests (RDTs) targeting histidine-rich protein 2 (HRP2) and parasite lactate dehydrogenase (pLDH) and microscopy, compared to nPCR as a reference standard. At enrolment, the proportion of pregnant women who were positive for P. falciparum by HRP2/pan pLDH RDT, Pf pLDH/pan pLDH RDT, microscopy and PCR was 38%, 29%, 36% and 44% in Uganda and 21%, 16%, 15% and 35% in Burkina Faso, respectively. All test positivity rates declined during follow-up. In comparison to PCR, the sensitivity of the HRP2/pan pLDH RDT, Pf pLDH/pan pLDH RDT and microscopy was 75.7%, 60.1% and 69.7% in Uganda, 55.8%, 42.6% and 55.8% in Burkina Faso respectively for all antenatal visits. Specificity was greater than 96% for all three tests. Comparison of accuracy using generalized estimating equation revealed that the HRP2- detecting RDT was the most accurate test in both settings. Conclusions/Significance The study suggests that HRP2-based RDTs are the most appropriate point-of-care test currently available for use during pregnancy especially for symptomatic women, but will still miss some PCR-positive women. The clinical significance of these very low density infections needs to be better defined. PMID

    Reported are our findings from a case-control study of the association between prolonged breast-feeding and clinical malnutrition in an urban setting in West Africa. The cases were children aged 12-36 months who had been hospitalized with a diagnosis of clinical malnutrition. Children of a similar age who lived in neighbouring courtyards were recruited as controls. For 152 case-control pairs in which both children were receiving solid foods, non-breast-feeding was associated with an increased risk of clinical malnutrition (crude odds ratio = 2.37; 95% confidence interval = 1.24, 4.55). This association remained statistically significant after controlling for various potentially confounding variables (P = 0.03). Our findings suggest that either prolonged breast-feeding may offer substantial protection against clinical malnutrition in the study population or malnutrition leads mothers to stop breast-feeding. These results are inconsistent with those of a number of workers who have reported that prolonged breast-feeding is associated with an increased risk of malnutrition. This inconsistency might have arisen because of differences in the definition of malnutrition used or because of variations in the quantity and quality of weaning foods available in different settings. We found no evidence to support the hypothesis that prolonged breast-feeding may be detrimental to children.

    The adoption of Artemisinin based combination therapies (ACT) constitutes a basic strategy for malaria control in sub-Saharan Africa. Moreover, since cases of ACT resistance have been reported in South-East Asia, the need to understand P. falciparum resistance mechanism to ACT has become a global research goal. The selective pressure of ACT and the possibility that some specific Pfcrt and Pfmdr1 alleles are associated with treatment failures was assessed in a clinical trial comparing ASAQ to AL in Nanoro. Dried blood spots collected on Day 0 and on the day of recurrent parasitaemia during the 28-day follow-up were analyzed using the restriction fragments length polymorphism (PCR-RFLP) method to detect single nucleotide polymorphisms (SNPs) in Pfcrt (codon76) and Pfmdr1 (codons 86, 184, 1034, 1042, and 1246) genes. Multivariate analysis of the relationship between the presence of Pfcrt and Pfmdr1 alleles and treatment outcome was performed. AL and ASAQ exerted opposite trends in selecting Pfcrt K76T and Pfmdr1-N86Y alleles, raising the potential beneficial effect of using diverse ACT at the same time as first line treatments to reduce the selective pressure by each treatment regimen. No clear association between the presence of Pfcrt and Pfmdr1 alleles carried at baseline and treatment failure was observed. PMID:27031231

    With the institution of the primary health care strategy in 1978 and the devaluation of the CFA franc in 1994 the French-speaking countries of Africa are striving to encourage the prescription of generic essential drugs. However, their prescription rates continue to remain low in these countries, especially in the major hospitals. The aim of this study was thus to determine how prescribers at the national hospital in Ouagadougou were informed about genetric drugs and to analyse their attitudes and practices with a view to elucidating the barriers to a more widespread use of generic essential drugs in hospital practice. The study consisted of a survey of all of the qualified prescribers (n=194) at Yalgado Ouedraogo University Hospital Centre in 1998. Thirty refused to participate and 35 questionnaires were discarded because they were poorly filled out. So, the responses of 129 (66.5%) prescribers in all were analysed. More than 80% (106/129) of the prescribers were aware of the existence of generic drugs in the hospital, but only 24.8% of them considered generics to have the same efficacy as their corresponding proprietary drugs. However, 64.3% of the prescribers felt that there was a place for generic drugs in a last-resort echelon of medical care, such as the national hospital in Ouagadougou, and 85.3 % were willing to prescribe them for their patients because of their low cost. The analysis of the data and the responses to the open questions show that the main conditions that would boost the prescription of generic essential drugs by hospital staff are as follows: generic essential drugs available in appropriate dosage forms and of guaranteed quality; appropriate basic training starting in medical and nursing schools; providing the prescribers with information and further education about generic drugs; and better dispensing of these drugs by the hospital's central pharmacy.

  8. Measuring turbidity, and indicator to evaluate drinkability of waters in Southern countries? Approaches from Burkina Faso, Sudan and Argentina case studies

    The relationship between proportion of suspended solids, dissolved oxygen and bacteriology has long been proven (Brock, 1966; Lechevallier et al., 1985; Bustina and Levallois, 2003; Chang and Liao, 2012), bacteria need coarse elements to hang on and develop. However, water bacteriology analyses are difficult to implement in southern countries. They are expensive and require sterile equipment, transport in cold conditions and a nearby laboratory, which remains difficult in remote areas under these hot latitudes. Yet, simple measurement devices allow to know in a few minutes the water turbidity. Is turbidity an efficient tool to evaluate the drinkability of water when no bacteriological analyses are possible? The results proposed here are taken from three different studies whose purposes were to measure different physical, chemical and bacteriological parameters of water used for human and/or animal consumption. One of the finalities was to propose a method, at lower cost, to evaluate the drinkability of water for consumption. Four case studies were chosen: the basin of the Doubegue River in Burkina Faso is a rural area of a developing country, where drinking water is taken from the alluvial aquifer close to the surface. Furthermore, the laundry is washed and the children play in running streams. Major expansion of the cultivated lands since 1980s has brought important soils losses, thus a chronicle contamination of surface water with suspended solids (Robert, 2012). The Mendoza and Tunuyán Rivers Basins in Argentina, an emerging country, have snow-glaciar regimes with naturally turbid waters. They supply drinking water to two towns, Mendoza and Tunuyán cities, respectively 1 million and 40,000 inhabitants. However, these two streams -whose watersheds are common- do not present the same managements: the Mendoza River has been equipped with large hydraulic infrastructures, moving the turbid waters into clear and erosive ones (Lavie, 2009), while the Tunuyán River

    Migration patterns in Burkina Faso, contributing factors, and migrant characteristics are examined. Data are from published literature for the years 1969-1973. Net emigration from Burkina Faso, primarily to the Ivory Coast and Ghana, is shown to be the predominant trend. The migrant population consists largely of men aged 15-30 from the rural Mossi regions. The socioeconomic context contributing to the observed emigration and the benefits to the communities of origin as a result of these movements are considered. The impact of return migration on agricultural development is discussed. PMID:12267600

    The distribution of organophosphate and carbamate resistance was investigated in 33 samples of Culex pipiens quinquefasciatus Say from 25 cities in Côte d'Ivoire and Burkina Faso. Organophosphate resistance levels were higher in Côte d'Ivoire than in Burkina Faso. Chlorpyrifos resistance ratios at LC95 ranged from 4 to 30 times in Côte d'Ivoire and from 3 to 6 times in Burkina Faso. For temephos, ratios ranged from 3 to 18 and from 1 to 2, respectively. Of 27 samples from Côte d'Ivoire, 25 also displayed cross resistance to carbamates as shown by a mortality plateau in bioassays with propoxur and carbosulfan (similar to chlorpyrifos). Cross resistance to organophosphates and carbamates was caused by an insensitive acetylcholinesterase allele (AceR). This gene was absent from Burkina Faso, except in Niangoloko near the Côte d'Ivoire border. Organophosphate resistance also was associated with the presence of A2-B2 overproduced esterases which had higher frequencies in Côte d'Ivoire (75-100%) than in Burkina Faso (40-50%). Two other esterases with the same electrophoretic mobility as C2 from Puerto Rico and B1 from California were identified for the 1st time in West Africa. "C2" was widespread, whereas "B1" was present in only a few mosquitoes from Côte d'Ivoire. These differences in resistance patterns should be taken into consideration in planning urban mosquito control strategies within 2 countries.

    Logos of the University of Ouagadougou, ISAPA and Universite Blaise Pascal Africa (especially Sub-Saharan Africa) is a continent where electrification is at a low level. However, the development of the electrical power sector is a prerequisite for the growth of other industrial activities, that is to say for the social and economic development of African countries. Consequently, a large number of electrification projects (rural electrification, interconnection of different country's grids) takes place in many countries. These projects need expertise and make Africa a continent of opportunity for companies in different domains for business and research: energy; energetic production, transmission, distribution and protection of electricity; the supply of cable; the construction, engineering and expertise in the field of solar and wind power. The first International Symposium on electrical Arc and thermal Plasma in Africa (ISAPA) was held for the first time in Ouagadougou, Burkina Faso to progress and develop the research of new physical developments, technical breakthroughs, and ideas in the fields of electrical production and electrical applications. The ISAPA aims to encourage the advancement of the science and applications of electrical power transformation in Africa by bringing together specialists from many areas in Africa and the rest of the world. Such considerations have led us to define a Scientific Committee including representatives from many countries. This first meeting was an innovative opportunity for researchers and engineers from academic and industrial sectors to exchange views and knowledge. Both fundamental aspects such as thermal plasma, electrical arc, diagnostics and applied aspects as circuit breakers, ICP analyses, photovoltaic energy conversion and alternative energies, as well as space applications were covered.

    As part of prevention of HIV mother-to-child transmission (PMTCT) strategies, HIV-positive women are asked to choose between two options regarding infant feeding: replacement feeding or exclusive breastfeeding with early weaning. Health services must offer women counseling, guidance, and support to enable them to make an informed choice. This article aims to shed light on the content of counseling and its adaptation to local situations, including women's perceptions, in three resource-poor countries with different infant feeding patterns (Burkina Faso, Cambodia, and Cameroon). The qualitative study included observations in health facilities and interviews with HIV-positive mothers and health workers. The results show that counseling practices vary, including prescriptive counseling proposing only one option to all women, an option based on the mother's economic level assessed by health care providers, and the choice between options. While health workers consider economic aspects first, women mostly consider social aspects related to the risk of being stigmatized as a "bad mother'" or as HIV-positive. Overall trends identify some limits to counseling effectiveness when considering women's perceptions and needs, such as: the content of information provided by health care providers, duration and timing of counseling, discrepancies between information provided during counseling and from the health system, and ranking of preventive options by health workers. Women's agency for feeding choices is related to local practices and local authorities' abilities to provide more or less comprehensive counseling based on the organization of the health and aid system. Local practices also depend on institutions' interpretations of international recommendations based on public health considerations regarding standard of care and women's and the health system's respective responsibilities. Beyond structural constraints that hinder the adoption of preventive infant feeding patterns

    The pathogenesis and pathology of African animal trypanosomosis (AAT) in Baoulé, N'Dama/Baoulé-cross-bred and Zebu cattle was studied from 1987 to 1991 in a series of experiments conducted under natural and artificial conditions of challenge at the Centre de Recherches sur les Trypanosomoses Animales (CRTA) in Burkina Faso. This first paper reports on the clinical performance of 64 Baoulé, 10 N'Dama/Baoulé-cross-bred and 20 Zebu cattle, which were transferred to the pastoral zone of Satiri, 50 km northeast of Bobo-Dioulasso, a zone infested with Glossina palpalis gambiensis, G. morsitans submorsitans and G. tachinoides. Prior to the experiment, the cattle had been raised in a fly proof stable and at the CRTA breeding station, an area of extremely low incidence of trypanosomosis or had been exposed at least once to natural trypanosome challenge in an area of high Glossina density. The cattle were monitored daily for clinical performance. Blood samples were collected twice weekly and examined on the spot for packed red cell volume (PCV) and parasitaemia. In the blood of 98% of the cattle trypanosomes (Trypanosoma vivax, T. congolense) were detected. Significant inter- and intrabreed differences with respect to the clinical performance were recorded. Regarding general health, the humpless Baoulé and N'Dama/Baoulé cross-bred cattle (Bos taurus) proved to be superior to the humped Zebu cattle (B. indicus) under this high challenge. Previous exposure to natural challenge had a positive effect on survival for both Baoulé and Zebu cattle. The phenotypic variation in response to trypanosomosis was small in Baoulé previously exposed and large in Baoulé previously not exposed.(ABSTRACT TRUNCATED AT 250 WORDS)

    Specimens described as Rhadinorhynchus niloticus Meyer, 1932 (Rhadinorhynchidae) from two male specimens collected from Heterotis niloticus (Cuvier) in the Egyptian Nile were later redescribed in the genus Tenuisentis Van Cleave, 1936 (Tenuisentidae) based on 12 specimens collected from the same host species in the White Nile. That redescription basically distinguished the two genera based on five traits but did not actually provide a formal description. His account left out information about cerebral ganglion, lemnisci, some reproductive structures, eggs, proboscis hook dissymmetry and roots, size of trunk and a few other structures. We provide (i) the first complete description of this species enhanced by SEM, molecular, and histo-pathological studies; (ii) expand the existing descriptions; (iii) correct questionable accounts advanced by Van Cleave on the cement gland and the hypodermal giant nuclei; and (iv) add descriptions of new features such as the para-receptacle structure which we also report from Paratenuisentis Bullock & Samuel, 1975, the only other genus in Tenuisentidae Van Cleave, 1936. The subsequent description of a few more specimens from the same host collected in Mali was more informative yet incomplete and at variance with our specimens from Burkina Faso. Genetic divergence and phylogenetic analyses of mitochondrial (cytochrome oxidase c subunit I; COI) and nuclear (18S ribosomal RNA) gene relationships uncovered a cryptic species complex containing two lineages. Based on our studies, the family diagnosis is emended. The acanthocephalan causes damage to the host intestine as depicted in histopathological sections. The invading worm can extend from the mucosal layer to the muscularis externa of the host with subsequent tissue necrosis, villi compression, haemorrhaging and blood loss. PMID:26790681

    Objective Preventive zinc supplementation in the form of tablets or syrup reduces the incidence of diarrhoea and acute lower respiratory tract infections (RTI), but its effect on malaria is inconsistent. When zinc is administered with other micronutrients or foods, its effect is also uncertain. We assessed the effects of different amounts and sources of zinc on the frequency of diarrhoea, malaria, fever and RTI in young children. Design, setting and populations This community-based, double-blind, placebo-controlled, cluster-randomised trial of 2435 children 9 months of age was carried out between April 2010 and July 2012 in rural southwestern Burkina Faso. Interventions Participants were randomly assigned at the concession level to receive daily 1 of 4 interventions for 9 months: (1) 20 g small-quantity lipid-based nutrient supplement (SQ-LNS) without zinc and placebo tablet, (2) 20 g SQ-LNS with 5 mg zinc and placebo tablet, (3) 20 g SQ-LNS with 10 mg zinc and placebo tablet or (4) 20 g SQ-LNS without zinc and 5 mg zinc tablet. Participants were visited weekly in their homes for morbidity surveillance for 9 months, and those with uncomplicated diarrhoea and malaria received treatment from the study field workers in the community. Main outcomes Incidence and longitudinal prevalence of diarrhoea, malaria, fever, and lower and upper RTI by intervention group. Results The incidence of diarrhoea, malaria and fever was 1.10 (±1.03 SD), 0.61 (±0.66 SD) and 1.49 (±1.12 SD) episodes per 100 child-days at risk, respectively, and did not differ by intervention group (p=0.589, p=0.856 and p=0.830, respectively). The longitudinal prevalence of acute lower RTI (0.1%; 95% IC 0.1–0.2%) and of upper RTI (7.8%; 95% IC 7.1–8.4%) did not differ among groups (p=0.234 and p=0.501, respectively). Conclusions Inclusion of 5 or 10 mg zinc in SQ-LNS and provision of 5 mg zinc dispersible tablet along with SQ-LNS had no impact on the incidence of diarrhoea

    Objectifs l’augmentation du taux de personnes qui connaissent leur statut VIH est un impératif, notamment en Afrique subsaharienne, ce qui impose d’évaluer les stratégies utilisées pour accroître la fréquentation des services de dépistage. Cet article vise à faire le bilan de la pertinence, de la faisabilité et de l’efficacité des campagnes nationales de dépistagemenées entre 2006 et 2010 au Burkina Faso. Méthodologie une analyse de toutes les données de fréquentation du conseil dépistage sur cette période a été faite, couplée à des entretiens avec les principaux acteurs intervenant dans le dépistage. Résultats les résultats montrent que les huit campagnes de dépistage organisées sur la période ont permis à 487 727 personnes de faire leur test VIH. Ce nombre représente 50 % du nombre total de personnes ayant fait leur test et contribue à hauteur de 24,6 % au dépistage des personnes séropositives identifiées au cours de cette période. Les campagnes ont touché des populations difficiles à atteindre (en particulier les jeunes), à un coût moindre. Conclusions cette stratégie est donc pertinente pour identifier les personnes VIH+. Son intérêt pour la prévention, important selon les soignants et au vu des populations jeunes qui y participent, devrait être mesuré par des études complémentaires. Les campagnes sont efficaces et coût-efficaces même dans un pays de niveau de prévalence faible. Ces résultats soulignent l’intérêt de la synergie entre les associations et les services de santé dans l’offre de services de conseil et dépistage. PMID:24681563

    La cataracte demeure la première cause de cécité dans les pays en voie de développement posant un problème de santé publique. Le but de cette étude est de faire le bilan d'une activité de chirurgie avancée de la cataracte par la technique dite de « phacoalternative » ou par tunnélisation. Il s'agissait d'une étude prospective de base réalisée au Burkina Faso portant sur la chirurgie de la cataracte par la technique de tunnélisation. L’âge moyen de nos patients atteints de cataracte était de 62,47 ± 12,77 ans avec un sex-ratio de 0,98. La majorité des patients opérés (82,82%) étaient des cultivateurs et des ménagères. L'acuité visuelle de loin était réduite à la perception lumineuse dans 68,70% des cas. La profondeur moyenne de la chambre antérieure était de 2,98 ± 0,53 mm. L’épaisseur moyenne du cristallin était de 3,55 ± 0,75 mm. La longueur axiale moyenne de l’œil de nos patients opérés de la cataracte était de 22,88 ± 0,90 mm. La puissance réfractive moyenne estimée de la cornée était de 43,21 ± 2,03 dioptries chez nos patients. La puissance moyenne estimée de l'implant intra oculaire (IOL) utilisé était de23,11 ± 2,35D. La majorité (79,6%) de nos patients avait une bonne acuité visuelle après la chirurgie de la cataracte par tunnélisation. La chirurgie de la cataracte par tunnélisation est une technique révolutionnaire adaptée aux pays pauvres d'Afrique. Elle permet une lutte efficace à moindre coût contre la cécité par cataracte dans nos régions. La tunnélisation est une technique chirurgicale adaptée pour lutter efficacement contre la cécité due à la cataracte en Afrique. PMID:27022426

    Introduction La mortalité néonatale demeure un problème majeur de santé publique dans les pays en développement. Notre étude avait pour but de déterminer la morbidité et la mortalité des nouveau-nés à Ouagadougou, Burkina Faso. Méthodes Une étude rétrospective sur 10 années a permis d'inclure tous les nouveau-nés admis dans l'Unité de Néonatologie de la Clinique El Fateh-Suka. Résultats Au total, 697 nouveau-nés étaient hospitalisés sur la période d'étude. Les principaux diagnostics étaient les infections néonatales (23.5%), les anomalies liées à la durée de la gestation et à la croissance du fætus (17.9%) et le paludisme congénital (15.1%). Les 91 (13.1%) décès étaient dus aux anomalies liées à la durée de la grossesse et à la croissance du fætus (46.1%), à l'hypoxie intra-utérine et à l'asphyxie obstétricale (20,9%) et aux infections néonatales (17.6%). Ces décès survenaient dans 81.3% dans les 72 heures, dans 93.4% des cas dans la première semaine d'hospitalisation. Le facteur de risque associé à ces décès était la voie basse d'accouchement (p = 0.02). Conclusion Cette étude a identifié des pathologies évitables déjà décrites comme les principales causes d'hospitalisations et de décès néonatals. La voie basse d'accouchement était le facteur de risque associé à ces décès, ce qui n'avait pas encore été rapporté. Les efforts pour améliorer la qualité des services de soins périnatals doivent être intensifiés afin de réduire la mortalité néonatale dans les pays en développement. PMID:23785558

    The expected growth in NCDs in cities is one of the most important health challenges of the coming decades in Sub-Saharan countries. This paper aims to fill the gap in our understanding of socio-economic differentials in NCD mortality and risk in low and middle income neighborhoods in urban Africa. We use data collected in the Ouagadougou Health and Demographic Surveillance System. 409 deaths were recorded between 2009-2011 among 20,836 individuals aged 35 years and older; verbal autopsies and the InterVA program were used to determine the probable cause of death. A random survey asked in 2011 1,039 adults aged 35 and over about tobacco use, heavy alcohol consumption, lack of physical activity and measured their weight, height, and blood pressure. These data reveal a high level of premature mortality due to NCDs in all neighborhoods: NCD mortality increases substantially by age 50. NCD mortality is greater in formal neighborhoods, while adult communicable disease mortality remains high, especially in informal neighborhoods. There is a high prevalence of risk factors for NCDs in the studied neighborhoods, with over one-fourth of the adults being overweight and over one-fourth having hypertension. Better-off residents are more prone to physical inactivity and excessive weight, while vulnerable populations such as widows/divorced individuals and migrants suffer more from higher blood pressure. Females have a significantly lower risk of being smokers or heavy drinkers, while they are more likely to be physically inactive or overweight, especially when married. Muslim individuals are less likely to be smokers or heavy drinkers, but have a higher blood pressure. Everything else being constant, individuals living in formal neighborhoods are more often overweight. The data presented make clear the pressing need to develop effective programs to reduce NCD risk across all types of neighborhoods in African cities, and suggest several entry points for community

    Usutu virus (USUV) was discovered in South Africa in 1959. Since then, it has been reported in several African countries including Senegal, Central African Republic, Nigeria, Uganda, Burkina Faso, Cote d'Ivoire, and Morocco. In 2001, USUV has been identified for the first time outside of Africa, namely in Europe, where it caused a significant mortality among blackbirds in Vienna, Austria. In 2009, the first two human cases of USUV infection in Europe have been reported in Italy, causing encephalitis in immunocompromised patients. The host range in Africa includes mainly Culex mosquitoes, birds, and also humans with one benign and one severe case. Given its role as a potential human pathogen and the similar appearance compared with other emerging arboviruses, it is essential to investigate the natural history and ecology of USUV in Africa. In this regard, we review the emergence of USUV in Africa, summarizing data about isolations, host range, and potential vectors, which should help to improve our understanding of the factors underlying the circulation of USUV in Europe and Africa.

    Hepatitis D virus (HDV) is a satellite of hepatitis B virus (HBV), and infection with this virus aggravates acute and chronic liver disease. While HBV seroprevalence is very high across sub-Saharan Africa, much less is known about HDV in the region. In this study, almost 2,300 blood serum samples from Burkina Faso (n = 1,131), Nigeria (n = 974), Chad (n = 50), and the Central African Republic (n = 118) were screened for HBV and HDV. Among 743 HBsAg-positive serum samples, 74 were positive for HDV antibodies and/or HDV RNA, with considerable differences in prevalence, ranging from <2% (pregnant women from Burkina Faso) to 50% (liver patients from Central African Republic). HDV seems to be much more common in chronic liver disease patients in the Central African Republic (CAR) than in similar cohorts in Nigeria. In a large nested mother-child cohort in Burkina Faso, the prevalence of HDV antibodies was 10 times higher in the children than in their mothers, despite similar HBsAg prevalences, excluding vertical transmission as an important route of infection. The genotyping of 16 full-length and 8 partial HDV strains revealed clade 1 (17/24) in three of the four countries, while clades 5 (5/24) and 6 (2/24) were, at least in this study, confined to Central Nigeria. On the amino acid level, almost all our clade 1 strains exhibited a serine at position 202 in the hepatitis D antigen, supporting the hypothesis of an ancient African HDV-1 subgroup. Further studies are required to understand the public health significance of the highly varied HDV prevalences in different cohorts and countries in sub-Saharan Africa. PMID:24599979

    In Africa, highly pathogenic avian influenza H5N1 virus was first detected in northern Nigeria and later also in other regions of the country. Since then, seven other African countries have reported H5N1 infections. This study reports a comparison of full-length genomic sequences of H5N1 isolates from seven chicken farms in Nigeria and chicken and hooded vultures in Burkina Faso with earlier H5N1 outbreaks worldwide. In addition, the antigenicity of Nigerian H5N1 isolates was compared with earlier strains. All African strains clustered within three sublineages denominated A (south-west Nigeria, Niger), B (south-west Nigeria, Egypt, Djibouti) and C (northern Nigeria, Burkina Faso, Sudan, Côte d'Ivoire), with distinct nucleotide and amino acid signatures and distinct geographical distributions within Africa. Probable non-African ancestors within the west Asian/Russian/European lineage distinct from the south-east Asian lineages were identified for each sublineage. All reported human cases in Africa were caused by sublineage B. Substitution rates were calculated on the basis of sequences from 11 strains from a single farm in south-west Nigeria. As H5N1 emerged essentially at the same time in the north and south-west of Nigeria, the substitution rates confirmed that the virus probably did not spread from the north to the south, given the observed sequence diversity, but that it entered the country via three independent introductions. The strains from Burkina Faso seemed to originate from northern Nigeria. At least two of the sublineages also circulated in Europe in 2006 as seen in Germany, further suggesting that the sublineages had already emerged outside of Africa and seemed to have followed the east African/west Asian and Black Sea/Mediterranean flyways of migratory birds.

    Malaria is the biggest killer of African children, yet it is cheaply preventable and curable with insecticides spraying, impregnated bednets and effective drugs. This study aimed to evaluate the quality of Chloroquine (CQ) tablets available in selected African countries. Twenty-six samples of antimalarial CQ tablet of 100, 150 and 250 mg were collected from 12 African countries and evaluated for their quality in the Drugs Quality Control Laboratory of Rabat, Morocco. The identification and dosage of active pharmaceutical ingredients in the tablets, dissolution rate, hardness and the friability of CQ tablets were performed according to the United States Pharmacopeia (USP) and European Pharmacopoeia (Eur.Ph.) recommended methods. The results showed that 7.7% of the sampled CQ tablets available in Burkina Faso were of low quality. Failure in dissolution profile was found in 50% of CQ tablets sampled from Benin, Burkina Faso, Comoros Union, Mali and Senegal. The findings showed poor quality of CQ tablets available in the African market. This problem may affect the efforts to control malaria in Africa. Efficient regulatory systems of drugs quality control should be implemented. PMID:22117854

    This article reviews scientific and other literature during the 1990s that links migration and mobility with the spread of sexually transmitted diseases (STDs), including HIV/AIDS. The focus is on key population groups linked to the spread of HIV and STDs in West and Central Africa: migrant laborers, truck drivers, itinerant traders, commercial sex workers (CSWs), and refugees. Countries with high emigration and immigration tend to have high levels of HIV infection, with the exception of Senegal. The main destination of immigrants are Senegal, Nigeria, and Cote d'Ivoire in West Africa and Cameroon, Congo, Gabon, and Congo in Central Africa. The risk of infection and the spread of HIV is variable among migrants. There is little in the literature that substantiates hypotheses about the strong association between migration and HIV-positive status. Information is needed on the duration, frequency of return visits, living conditions, sexual activities with multiple partners, and information before departure, along the routes, at final destination, and at the time of returns. Action-based research in five West African countries (Burkina Faso, Cote d'Ivoire, Mali, Niger, and Senegal) should produce results in late 1998. Comparable studies in Central Africa are unknown. Regional studies should be complemented by local studies. Prevention would benefit from studies on the relative size of these five population groups by geographic location.

    The University Corporation for Atmospheric Research (UCAR) Africa Initiative (AI) is a coordinated effort aimed at building sustainable partnerships between UCAR and African institutions in order to pursue research and applications for the benefit of the African people. The initiative is based on four fundamental operating principles, concisely summarized by the overall philosophy of enabling African solutions to African needs. The four principles are: • Collaborate with African institutions • Focus on institutional capacity building and research support • Explore science research themes critical to Africa and important for the world • Leverage the research infrastructure in UCAR to add value These principles are realized in a set of pilot activities, chosen for their high probability of short-term results and ability to set the stage for longer-term collaboration. The three pilot activities are listed below. 1. A modest radar network and data-distribution system in Mali and Burkina Faso, including a data-sharing MOU between the Mail and Burkina Faso Weather Services. 2. A partnership among UCAR, the Ghana Meteorological Agency, and the Ghana university community to develop an operational Weather Research and Forecasting (WRF) model for West Africa. The output is used by researchers and operational forecasters in Africa. Model output is also part of a demonstration project that aims to allow humanitarian agencies to share geo-referenced information in Africa via a web portal. 3. A workshop in Ouagadougou, Burkina Faso from April 2-6, 2007, with the theme Improving Lives by Understanding Weather. The workshop, co-organized with Programme SAAGA and the Commité Permanent Inter-Etats de Lutte Contre la Sécheresse dans le Sahel (CILSS), included over 80 participants from 18 countries, and produced a set of recommendations for continued collaboration. Our presentation will provide an update of these pilot activities and point to future directions. Recognizing

    Agriculture is the main source of income for population and the main driver of economy in Africa, particularly in West Africa. West African agriculture is dominated by rainfed agriculture. This agricultural system is characterized by smallholder and subsistence farming, and a limited use of crop production inputs such as machines, fertilizers and pesticides. Therefore, crop yield is strongly influenced by climate fluctuation and is more vulnerable to climate change and climate variability. To reduce climate risk on crop production, a development of tailored agricultural management strategies is required. The usage of agricultural management strategies such as tailored crop planting date might contribute both to reduce crop failure and to increased crop production. In addition, unlike aforementioned crop production inputs, the usage of tailored planting dates is costless for farmers. Thus, efforts to improve crop production by optimizing crop planting date can contribute to alleviate food insecurity in West Africa, in the context of climate change. In this study, the process-based crop model GLAM (General Large Area Model for annual crop) in combination with a fuzzy logic approach for planting date have been coupled with a genetic algorithm to derive Optimized Planting Dates (OPDs) for maize cropping in Burkina Faso, West Africa. For a specific location, the derived OPDs correspond to a time window for crop planting. To analyze the performance of the OPDs approach, the derived OPDs has been compared to two well-known planting date methods in West Africa. The results showed a mean OPD ranging from May 1st (South-West) to July 11th (North) across the country. In comparison with well-known methods, the OPD approach yielded earliest planting dates across Burkina Faso. The deviation of OPDs from planting dates derived from the well known methods ranged from 10 days to 20 days for the northern and central region, and less than 10 days for the southern region.

    Introduction L'infection au VIH chez les nouveau-nés par leur mère peut être réduite grâce à des programmes de prévention de transmission mère-enfant du VIH (PTME). L'objectif dans cette étude était d’évaluer le traitement antirétroviral chez les femmes enceintes VIH-1 positif sur la transmission mère-enfant de l'infection au Centre Médical Saint Camille de Ouagadougou, Burkina Faso. Méthodes Des échantillons de spot de sang total ont été collectés chez 160 enfants âgés de 6 semaines, nés de mères VIH-1 positif et chez 40 enfants âgés de 2 à 13 mois provenant d'orphelinats et dont les mères étaient inconnues. Ces échantillons ont été testés avec le kit Abbott Real Time HIV-1 Qualitative. Un questionnaire a permis de connaitre les âges et les fonctions des femmes enceintes. Résultats Les femmes enceintes avaient un âge moyen global de 29,50±5,19 ans. Au total, 50,5% (101/200) ont été mises sous combinaison AZT/3TC/NVP et 29,5% (59/200) étaient sous prophylaxie (AZT/3TC). Le taux de transmission verticale du VIH-1 était de 0,0% (0/160) (p < 0,001) chez les enfants dont les mères étaient sous combinaison AZT/3TC/NVP ou sous prophylaxie AZT/3TC et de 15,0% (6/40) chez les enfants orphelins qui n’étaient pas inclus dans le protocole de la PTME. Conclusion Selon les résultats, le protocole de la PTME est efficace et réduit très significativement le risque de transmission du VIH-1 de la mère à l'enfant. De plus, le dépistage par PCR, des enfants orphelins infectés verticalement par le VIH, permet leur prise en charge thérapeutique précoce. PMID:26301003

    Introduction Les herpès virus EBV, CMV et HHV-6 sont des virus qui évoluent sous le modèle pandémique et sont responsables d’infections congénitales pouvant provoquer des séquelles graves chez les nouveau-nés. L’objectif de cette étude était de déterminer les prévalences de CMV, EBV et HHV-6 chez les femmes enceintes VIH(+) et VIH(-) à Ouagadougou. Méthodes Dans cette étude 200 échantillons de plasma sanguin de femmes enceintes dont 100 femmes VIH(+) et 100 femmes VIH(-) ont été diagnostiqués par PCR multiplex en temps réel pour les trois infections (EBV, CMV et HHV-6). Résultats Sur l’ensemble des 200 échantillons analysés, 18 (9,0%) étaient positifs à au moins un des trois virus, 12 (6,0%) étaient positifs au EBV, 13 (6,5%) au CMV et 12 (6,0%) positifs au HHV-6. Parmi les 18 cas d’infections, nous avons trouvé 10 cas (55,6%) de coïnfections dont 90,0% (9/10) d’infection multiple EBV/CMV/HHV6 et 10,0% de coinfection EBV/HHV6. Le taux d’infection HHVs était plus élevé chez les femmes VIH(-) que celles VIH(+) (12,0% versus 6,0%). Parmi les VIH(+), la PCR a révélé 7,1% (soit 6/85) d’infection HHVs chez celles qui n’étaient pas sous ARV contre 0% chez celles sous ARV. Conclusion Les herpès virus sont fréquents chez les femmes enceintes au Burkina Faso et pourraient constituer une menace chez ces dernières à cause des complications et des risques d’infection pour le nouveau-né.

    Introduction Il s'agit d'analyser la prise en charge du nouveau-né dans le cadre de la stratégie na-tionale de subvention des accouchements et des soins obstétricaux et néonatals d'urgence mis en place par le gouvernement du Burkina Faso en 2006. Méthodes Nous avons menée une étude à visée descriptive et analytique comportant un volet ré-trospectif du 01 janvier 2006 au 31 décembre 2010 portant sur les paramètres épidémiologiques, cliniques des nouveau-nés hospitalisés et un volet prospectif du 3 octobre 2011 au 29 février 2012 par une entrevue des accompagnateurs des nouveau-nés et des prestataires des services de santé. Résultats Les hospitalisations ont augmenté de 43,65% entre 2006 à 2010 Le taux de mortalité néo-natale hospitalière qui était de 11,04% a connu une réduction moyenne annuelle de 3,95%. L'entrevue a porté sur 110 accompagnateurs et 76 prestataires. La majorité des prestataires (97,44%) et des ac-compagnateurs (88,18%) étaient informés de la stratégie mais n'avait pas une connaissance exacte de sa définition. Les prestataires (94,74%) ont signalé des ruptures de médicaments, consommables médicaux et des pannes d’ appareils de laboratoire et d'imagerie. Parmi les accompagnateurs (89%) disaient être satisfaits des services offerts et (72,89%) trouvaient les coûts abordables mais évoquaient les difficultés du transport. Conclusion: La subvention a amélioré la prise en charge du nou-veau-né mais son optimisation nécessiterait une meilleur information et implication de tous les acteurs. Conclusion La subvention a amélioré la prise en charge du nouveau-né mais son optimisation nécessiterait une meilleur information et implication de tous les acteurs. PMID:26161166

    High relative poverty levels in Africa are attributed to the continent's under performing agriculture. Drought, low-yielding crop varieties, pests and diseases, poor soils, low fertilizer use, limited irrigation and lack of modern technologies are among the problems that plague African agriculture. Genetically modified (GM) crops may possess attributes that can help overcome some of these constraints, but have yet to be fully embraced in the mix of technology solutions for African agriculture. Cognizant of this, South Africa, Burkina Faso and Egypt are steadily growing GM crops on a commercial scale. Countries like Kenya, Nigeria, and Uganda are increasingly field-testing these crops with the view to commercialize them. These countries show strong government support for GM technology. Progress by these first adopter nations provides an insight as to how GM crops are increasingly being viewed as one of the ways in which the continent can invigorate the agriculture sector and achieve food security.

    The WAHARA project aims to increase the potential of water harvesting in Africa. The WAHARA project draws on expertise and field data from four study sites in Ethiopia, Tunisia, Burkina Faso and Zambia. The project is transdisciplinary working closely with stakeholders to ensure that the water harvesting technologies selected and tested meet their needs. The effectiveness of WH technologies will be assessed under different environmental and socio-economic conditions. Each study site offers a number of WH technologies and aim to trial technologies from other study sites. The results from the study sites will inform the adaptation of the PESERA model and the potential of WH for the whole of Africa This presentation highlights the climate range in which the field trials are being carried out and the technologies being trialed in northern Ethiopia. Conceptual models for each technology are considered and incorporated into the PESERA model. The model is applied for the study site with both field based and catchment based technologies being assessed. The transferability and potential of individual and combined technologies will be considered across climate gradients and soil type for Africa. A quick assessment tool has been developed and offers an initial assessment of water harvesting potential. The tool can be used to quickly assess which kinds of WHT could be used in specific areas in Africa and is available to interested parties.

    We used seasonal ground total counts and remote sensing and GIS technology to relate elephant (Loxodonta africana africana) distribution at Nazinga Game Ranch to environmental and anthropogenic factors. Variables used in analyses were normalized difference vegetation index, elevation, stream density, density of poaching and human illegal activities, distance to dams, distance to rivers, distance to roads, and distance to poaching risk. Contrary to our expectation, road traffic did not disturb elephants. Strong negative relationships were documented between elephant abundance and stream density, distance to dams, and poaching density. Density of poaching and other human illegal activities explained 81%, vegetation greenness 6%, and stream density 3% of the variation in elephant density. Elephant distribution represented a survival strategy affected by poaching, food quality and abundance, and water availability.

    After a strong reduction in investments in water infrastructure in Sub-Saharan Africa, we now see a revival and increased interest to start water-related projects. The global political willingness to work towards the UN millennium goals are an important driver behind this recent development. Large scale irrigation projects, such as were constructed at tremendous costs in the 1970's and early 1980's, are no longer seen as the way forward. Instead, the construction of a large number of small, village-level irrigation schemes is thought to be a more effective way to improve food production. Such small schemes would fit better in existing and functioning governance structures. An important question now becomes what the cumulative (downstream) impact is of a large number of small irrigation projects, especially when they threaten to deplete transboundary water resources. The Volta Basin in West Africa is a transboundary river catchment, divided over six countries. Of these six countries, upstream Burkina Faso and downstream Ghana are the most important and cover 43% and 42% of the basin, respectively. In Burkina Faso (and also North Ghana), small reservoirs and associated irrigation schemes are already an important means to improve the livelihoods of the rural population. In fact, over two thousand such schemes have already been constructed in Burkina Faso and further construction is to be expected in the light of the UN millennium goals. The cumulative impact of these schemes would affect the Akosombo Reservoir, one of the largest manmade lakes in the world and an important motor behind the economic development in (South) Ghana. This presentation will put forward an analytical framework that allows for the impact assessment of (large) ensembles of small reservoirs. It will be shown that despite their relatively low water use efficiencies, the overall impact remains low compared to the impact of large dams. The tools developed can be used in similar settings elsewhere

    Sub-Saharan West Africa is a vulnerable region where a better quantification and understanding of the impact of climate change on crop yields is urgently needed. Here, we have applied the process-based crop model SARRA-H calibrated and validated over multi-year field trials and surveys at eight contrasting sites in terms of climate and agricultural practices in Senegal, Mali, Burkina Faso and Niger. The model gives a reasonable correlation with observed yields of sorghum and millet under a range of cultivars and traditional crop management practices. We applied the model to more than 7000 simulations of yields of sorghum and millet for 35 stations across West Africa and under very different future climate conditions. We took into account 35 possible climate scenarios by combining precipitation anomalies from -20% to 20% and temperature anomalies from +0 to +6 °C. We found that most of the 35 scenarios (31/35) showed a negative impact on yields, up to -41% for +6 °C/ - 20% rainfall. Moreover, the potential future climate impacts on yields are very different from those recorded in the recent past. This is because of the increasingly adverse role of higher temperatures in reducing crop yields, irrespective of rainfall changes. When warming exceeds +2 °C, negative impacts caused by temperature rise cannot be counteracted by any rainfall change. The probability of a yield reduction appears to be greater in the Sudanian region (southern Senegal, Mali, Burkina Faso, northern Togo and Benin), because of an exacerbated sensitivity to temperature changes compared to the Sahelian region (Niger, Mali, northern parts of Senegal and Burkina Faso), where crop yields are more sensitive to rainfall change. Finally, our simulations show that the photoperiod-sensitive traditional cultivars of millet and sorghum used by local farmers for centuries seem more resilient to future climate conditions than modern cultivars bred for their high yield potential (-28% versus -40% for

    The legume pod borer, Maruca vitrata, is an endemic insect pest that causes significant yield loss to the cowpea crop in West Africa. The application of population genetic tools is important in the management of insect pests but such data on M. vitrata is lacking. We applied a set of six microsatellite markers to assess the population structure of M. vitrata collected at five sites from Burkina Faso, Niger and Nigeria. Observed polymorphisms ranged from one (marker 3393) to eight (marker 32008) alleles per locus. Observed and expected heterozygosities ranged from 0.0 to 0.8 and 0.0 to 0.6, respectively. Three of the loci in samples from Nigeria and Burkina Faso deviated significantly from Hardy-Weinberg Equilibrium (HWE), whereas no loci deviated significantly in samples from Niger. Analysis of molecular variance (AMOVA) indicated that 67.3% level of the genetic variation was within individuals compared to 17.3% among populations. A global estimate of F ST=0.1 (ENA corrected F ST=0.1) was significant (P⩽0.05) and corroborated by pairwise F ST values that were significant among all possible comparisons. A significant correlation was predicted between genetic divergence and geographic distance between subpopulations (R2=0.6, P=0.04), and cluster analysis by the program STRUCTURE predicted that co-ancestry of genotypes were indicative of three distinct populations. The spatial genetic variance among M. vitrata in West Africa may be due to limited gene flow, south-north seasonal movement pattern or other reproductive barriers. This information is important for the cultural, chemical and biological control strategies for managing M. vitrata.

  20. Mapping and analyzing urban growth in West Africa

    Africa has experienced the highest urban growth (~3.5% per year) in the developing world. West Africa in particular has seen significant urban growth mainly driven by the high natural population growth rate and the increasing percentage of population moving to urban areas. Urban growth in West Africa is expected to continue in decades to come. This study uses Landsat data at five different time steps (1970, 1980, 1990, 2000, and 2010) to map four cities from four different eco-regions of West Africa since the early 1970s. The selected four cities, Kumasi in Ghana, Abuja in Nigeria, Tahoua in Niger and Ouagadoughou in Burkina Faso, are some of the fastest growing cities in the region. We selected the cities in the following ecoregions: Eastern Guinean Forest, Guinean Forest-Savanna Mosaic, Sahelian Acacia Savanna and West Sudanian Savanna. We hypothesize that urban growth in West Africa is different compared to the other parts of the world primarily due to the dependency of about 60 percent of active labor force on subsistence agriculture in the region. As agriculture productivity is dependent on favorable climatic conditions (i.e., good rainfall, suitable temperature), any variability in climate impends the livelihood of subsistence farmers triggering the movements of more people towards the cities. Therefore, studying urban growth based on ecoregions help to better explain the urban development in West Africa. After mapping the urban areas, this study makes a comparative analysis of the temporal and spatial pattern of the urban growths across the ecoregions in West Africa.

    Despite the reported benefits of conservation agriculture (CA), its wider up-scaling in Sub-Saharan Africa (SSA) has remained fairly limited. This paper shows how a newly developed qualitative expert assessment approach for CA adoption (QAToCA) was applied to determine its adoption potential in SSA. CA adoption potential is not a predictor of observed adoption rates. Instead, our aim was to systematically check relevant factors that may be influencing its adoption. QAToCA delivers an assessment of how suitable conditions "and thus the likelihood for CA adoption" are. Results show that the high CA adoption potentials exhibited by the Malawi and Zambia case relate mostly to positive institutional factors. On the other hand, the low adoption potential of the Zimbabwe case, in spite of observed higher estimates, is attributed mainly to unstable and less secured market conditions for CA. In the case of Southern Burkina Faso, the potential for CA adoption is determined to be high, and this assessment deviates from lower observed figures. This is attributed mainly to strong competition of CA and livestock for residues in this region. Lastly, the high adoption potential found in Northern Burkina Faso is explained mainly by the fact that farmers here have no alternative other than to adopt the locally adapted CA system—Zaï farming. Results of this assessment should help promoters of CA in the given regions to reflect on their activities and to eventually adjust or redesign them based on a more explicit understanding of where problems and opportunities are found.

    Crop models are common tools for simulating crop yields and crop production in studies on food security and global change. Various uncertainties however exist, not only in the model design and model parameters, but also and maybe even more important in soil, climate and management input data. We analyze the performance of the point-scale crop model APSIM and the global scale crop model LPJmL with different climate and soil conditions under different agricultural management in the low-input maize-growing areas of Burkina Faso, West Africa. We test the models’ response to different levels of input information from little to detailed information on soil, climate (1961-2000) and agricultural management and compare the models’ ability to represent the observed spatial (between locations) and temporal variability (between years) in crop yields. We found that the resolution of different soil, climate and management information influences the simulated crop yields in both models. However, the difference between models is larger than between input data and larger between simulations with different climate and management information than between simulations with different soil information. The observed spatial variability can be represented well from both models even with little information on soils and management but APSIM simulates a higher variation between single locations than LPJmL. The agreement of simulated and observed temporal variability is lower due to non-climatic factors e.g. investment in agricultural research and development between 1987 and 1991 in Burkina Faso which resulted in a doubling of maize yields. The findings of our study highlight the importance of scale and model choice and show that the most detailed input data does not necessarily improve model performance.

  4. Trends and Projections of Climatic Extremes in the Black Volta Basin, West Africa: Towards Climate Change Adaptation.

    The water resources of the Black Volta Basin in West Africa constitute a major resource for the four countries (Burkina Faso, Ghana, Côte d'Ivoire, Mali) that share it. For Burkina Faso and Ghana, the river is the main natural resource around which the development of the diverse sectors of the two economies is built. Whereas Ghana relies heavily on the river for energy, land-locked Burkina Faso continuously develops the water for agricultural purposes. Such important role of the river makes it an element around which there are potential conflicts: either among riparian countries or within the individual countries themselves. This study documents the changes in temperature and precipitation extremes in the Black Volta Basin region for the past (1981-2010) and makes projections for the mid-late 21st century (2051-2080) under two emission scenarios; RCP 2.6 and RCP 8.5. The Expert Team on Climate Change Detection and Indices (ETCCDI) temperature- and precipitation-based indices are computed with the RClimdex software. Observed daily records and downscaled CORDEX data of precipitation and maximum and minimum temperatures are used for historical and future trend analysis respectively. In general low emission scenarios show increases in the cold extremes. The region shows a consistent pattern of trends in hot extremes for the 1990's. An increasing trend in hot extremes is expected in the future under RCP 8.5 while RCP 2.5 shows reductions in hot extremes. Regardless of the emission scenario, projections show more frequent hot nights in the 21st century. Generally, the region shows variability in trends for future extreme precipitation indices with only a few of the trends being statistically significant (5% level). Results obtained provide a basic and first step to understanding how climatic extremes have been changing in the Volta Basin region and gives an idea of what to expect in the future. Such studies will also help in making informed decisions on water management

    Background Mastitis constitutes an important risk factor in HIV vertical transmission. Very little, however, is known on how women in sub-Saharan Africa conceptualise health problems related to breastfeeding, such as mastitis, and how they act when sick. We aimed at filling this gap in knowledge, by documenting the indigenous nosography of mastitis, health seeking behaviour, and remedies for prophylaxis and treatment in rural sub-Saharan Africa. Methods The study was conducted in the Nouna Health District, rural Burkina Faso. We employed a combination of in-depth individual interviews and focus group discussions reaching both women and guérisseuers. All material was transcribed, translated, and analysed inductively, applying data and analyst triangulation. Results Respondents perceived breast problems related to lactation to be highly prevalent and described a sequence of symptoms which resembles the biomedical understanding of pathologies related to breastfeeding, ranging from breast engorgement (stasis) to inflammation (mastitis) and infection (breast abscess). The aetiology of disease, however, differed from biomedical notions as both women and guerisseurs distinguished between "natural" and "unnatural" causes of health problems related to breastfeeding. To prevent and treat such pathologies, women used a combination of traditional and biomedical therapies, depending on the perceived cause of illness. In general, however, a marked preference for traditional systems of care was observed. Conclusion Health problems related to breastfeeding are perceived to be very common in rural Burkina Faso. Further epidemiological research to assess the actual prevalence of such pathologies is urgently needed to inform the design of adequate control measures, especially given the impact of mastitis on HIV vertical transmission. Our investigation into local illness concepts and health care seeking behaviour is useful to ensure that such measures be culturally sensitive. Further

    Objective The hypertension epidemic in Africa collectively with very low rates of blood pressure control may predict an incremented prevalence of resistant hypertension (RH) across the continent. The aim of this study was to determine the prevalence of RH and associated risk factors in Africa. Data sources We conducted a comprehensive search of electronic databases (PubMed, EMBASE, Africa Wide Information and Africa Index Medicus) completed by manual search of articles, regardless of language or publication date. Methods We included studies which have reported the prevalence and/or risk factors for RH in Africa from inception to 19 May 2016. Forest plots were drawn to visualise the combined prevalence of RH and extent of statistical heterogeneity between studies. Results Out of 259 retrieved studies, only 5 from Cameroon, Nigeria, Burkina Faso, Lesotho and Algeria with a total population of 4 068 patients were finally included in this review. There was no study from the Eastern part of Africa. Though the definition of RH was not similar across studies, its prevalence was respectively 11.7%, 4.9%, 14.6%, 14.3% and 19.0%, with an overall pooled prevalence of 12.1% (95% CI 8.0% to 17.7%). Potential risk factors were: non-compliance to treatment, ageing, male sex, dyslipidaemia, metabolic syndrome, previous cardiovascular events, physical inactivity and stress, but not excessive salt intake, alcohol and coffee ingestions. Moreover, diabetes, smoking, obesity and renal insufficiency yielded discrepant results. Conclusions There is a huge dearth of research on the epidemiology of RH in Africa. Thereby, an extensive study of RH prevalence and risk factors is still largely warranted to curtail the high and continuously increasing burden of hypertension across Africa. PMID:27650760

    In September 1994, there will be a crucial vote in international public health: the nomination of the World Health Organization (WHO)'s next regional director for Africa. The appointment will affect how $850 million is spent and what happens to the health of 550 million of the world's poorest people. The current regional director, Dr Lobe Monekosso, took office 10 years ago, and just over half of the region's $136 million budget for 1992-3 reached the region's 45 member states. The rest of the budget was spent at the regional office in Zaire, along with 2/3 of the 112 million pounds sterling donated for the AIDS and immunization programs. Chronic difficulties caused by Africa's lack of infrastructure have been aggravated by civil unrest in Brazzaville, where the regional office is based, which prevented the WHO's auditors from evaluating biennial spending. The main contender for the post is Dr. Ebrahim Samba, director of the onchocerciasis control program, who took over the ailing program in 1980 and has turned it into a success. From its base in Ouagadougou in Burkina Faso, it has cut the prevalence of onchocerciasis as a public health problem in 11 West African countries from 95% in 1974 to less than 5%. The appointment will be decided by the regional committee, which is made up of health ministers of the region's 45 member states, and the incumbent has the upper hand. Regardless of the result of the regional committee meeting in Brazzaville, the time has come for a thorough review of the effectiveness of the WHO in Africa to reassure those treasury officials in donor countries waiting to withdraw their funds. The WHO needs to reform its selection procedures and make its regional directors more answerable to the World Health Assembly; in this way it will eliminate the existing potential for too much power combined with too little accountability.

    ABSTRACT Burkholderia pseudomallei, an environmental bacterium that causes the deadly disease melioidosis, is endemic in northern Australia and Southeast Asia. An increasing number of melioidosis cases are being reported in other tropical regions, including Africa and the Indian Ocean islands. B. pseudomallei first emerged in Australia, with subsequent rare dissemination event(s) to Southeast Asia; however, its dispersal to other regions is not yet well understood. We used large-scale comparative genomics to investigate the origins of three B. pseudomallei isolates from Madagascar and two from Burkina Faso. Phylogenomic reconstruction demonstrates that these African B. pseudomallei isolates group into a single novel clade that resides within the more ancestral Asian clade. Intriguingly, South American strains reside within the African clade, suggesting more recent dissemination from West Africa to the Americas. Anthropogenic factors likely assisted in B. pseudomallei dissemination to Africa, possibly during migration of the Austronesian peoples from Indonesian Borneo to Madagascar ~2,000 years ago, with subsequent genetic diversity driven by mutation and recombination. Our study provides new insights into global patterns of B. pseudomallei dissemination and adds to the growing body of evidence of melioidosis endemicity in Africa. Our findings have important implications for melioidosis diagnosis and management in Africa. IMPORTANCE Sporadic melioidosis cases have been reported in the African mainland and Indian Ocean islands, but until recently, these regions were not considered areas where B. pseudomallei is endemic. Given the high mortality rate of melioidosis, it is crucial that this disease be recognized and suspected in all regions of endemicity. Previous work has shown that B. pseudomallei originated in Australia, with subsequent introduction into Asia; however, the precise origin of B. pseudomallei in other tropical regions remains poorly understood

    This document describes the contents of a digital database containing maximum potential aboveground biomass, land use, and estimated biomass and carbon data for 1980. The biomass data and carbon estimates are associated with woody vegetation in Tropical Africa. These data were collected to reduce the uncertainty associated with estimating historical releases of carbon from land use change. Tropical Africa is defined here as encompassing 22.7 x 10{sup 6} km{sup 2} of the earth's land surface and is comprised of countries that are located in tropical Africa (Angola, Botswana, Burundi, Cameroon, Cape Verde, Central African Republic, Chad, Congo, Benin, Equatorial Guinea, Ethiopia, Djibouti, Gabon, Gambia, Ghana, Guinea, Ivory Coast, Kenya, Liberia, Madagascar, Malawi, Mali, Mauritania, Mozambique, Namibia, Niger, Nigeria, Guinea-Bissau, Zimbabwe (Rhodesia), Rwanda, Senegal, Sierra Leone, Somalia, Sudan, Tanzania, Togo, Uganda, Burkina Faso (Upper Volta), Zaire, and Zambia). The database was developed using the GRID module in the ARC/INFO{trademark} geographic information system. Source data were obtained from the Food and Agriculture Organization (FAO), the U.S. National Geophysical Data Center, and a limited number of biomass-carbon density case studies. These data were used to derive the maximum potential and actual (ca. 1980) aboveground biomass values at regional and country levels. The land-use data provided were derived from a vegetation map originally produced for the FAO by the International Institute of Vegetation Mapping, Toulouse, France.

    This edition of Cahiers Quebecois de Demographie is dedicated to the important evolution in the demographic production in French speaking Africa, with the exception of one article on fertility trends in Haiti. Between the 1960s until about the 1980s, African demography settled down to the heavy task of filling the void in demographic data. Data collection and development of new analysis techniques characterize the type of training received by demographers and their scientific production, most often realized in the teaching of national statistics. During this period, African demography contributed much to the advancement of demography, especially certain concepts and tools for collection and analysis. It faced declared limits in classical definitions of household, migration, and forms of union. It yearned to forge definitions which better fit the African context. It uses historical calendars to collect data on age in populations which do not always know their birth year. It developed the technique of observation to collect data on nomads. Africa had been the place entitled to the development of indirect estimation methods. Demographic works in Africa have participated in the restatement of the demographic transition theory and the reversal of intergenerational transfers theory. Since the end of the 1980s, African demography has moved in a social and explicative direction. One article in this edition concerns a new proposed method to comprehend the notion of family ties in demographic surveys, especially those examining migrants to Dakar and Bamako. Another article explores the implications of a very young age structure in Africa. Another article analyzes the differential factors of intergenerational intervals while considering all at once demographic variables and socioeconomic variables. Another articles addresses excess female mortality, especially after three months, in Mali. Two articles examine female migration towards Lome, Togo, and in Burkina Faso. PMID

    Salmonella enterica serovar Typhi and nontyphoidal Salmonella (NTS) cause the majority of bloodstream infections in sub-Saharan Africa; however, serotyping is rarely performed. We validated a multiplex polymerase chain reaction (PCR) assay with the White-Kauffmann-Le Minor (WKLM) scheme of serotyping using 110 Salmonella isolates from blood cultures of febrile children in Ghana and applied the method in other Typhoid Fever Surveillance in Africa Program study sites. In Ghana, 47 (43%) S. Typhi, 36 (33%) Salmonella enterica serovar Typhimurium, 14 (13%) Salmonella enterica serovar Dublin, and 13 (12%) Salmonella enterica serovar Enteritidis were identified by both multiplex PCR and the WKLM scheme separately. Using the validated multiplex PCR assay, we identified 42 (66%) S. Typhi, 14 (22%) S. Typhimurium, 2 (3%) S. Dublin, 2 (3%) S. Enteritidis, and 4 (6%) other Salmonella species from the febrile patients in Burkina Faso, Guinea-Bissau, Madagascar, Senegal, and Tanzania. Application of this multiplex PCR assay in sub-Saharan Africa could advance the knowledge of serotype distribution of Salmonella.

    Based on the United Nations study, "AIDS and the Demography of Africa", population growth rates will remain high in African countries south of the Sahara despite high mortality due to acquired immunodeficiency syndrome (AIDS). The Population Division of the UN Department for Economic and Social Information and Policy Analysis (DESIPA) incorporated the demographic impact of AIDS in its biennial population estimates and projections for Benin, Burkina Faso, Burundi, Central African Republic, Congo, Ivory Coast, Kenya, Malawi, Mozambique, Rwanda, United Republic of Tanzania, Uganda, Zaire, Zambia, and Zimbabwe. 9 million additional deaths due to AIDS are projected by 2005; 61% will occur in Uganda, Zaire, Tanzania, and Zambia. From 2000 to 2005, the average life expectancy for the region (51.2 years) will be 6.5 years lower than that without AIDS; that in Uganda (42.9 years) will be 11.1 years less. Mortality is increasing and its hardest impact will be during the prime working and family care years. Socioeconomic effects may include reductions in the size and productivity of the labor force, decreased industrial and agricultural production, and changes in care of children and the elderly. Due to high fertility rates, however, population increases are projected for all 15 countries. Although its nearly 12.4 million years less (4%) than that expected without the effect of AIDS, the total population for the region is projected to be 297.9 million by 2005.

    This article presents the publication ¿Women of the World--Francophone Africa: Laws and Policies Affecting their Reproductive Lives,¿ by Codou Bop, a Senegalese women's rights activist. This book contains a comprehensive review of the reproductive health and rights of women in Benin, Burkina Faso, Cameroon, Cote d'Ivoire, Mali, Senegal, and Chad. It provides practical and legal guidelines for rights advocates and identifies problem issues in the region. Each country was examined in terms of its political framework, sources for governing laws, customary laws and health, population and family planning policies. Across the seven nations, similar problems in restrictive abortion laws, high maternal mortality rates, high HIV/AIDS prevalence rates, low contraceptive use and the continuation of harmful traditional practices were noted. Likewise, legal status of women in the context of their right to be free from discrimination and issues affecting adolescents were examined. During the launching of the book, representatives from the featured countries were able to discuss strategies for revising laws and adopting better policies to protect the rights and welfare of women.

    As the global climate changes and the populations of many African countries grow, ensuring clean drinking water and food has become a pressing concern. Because of their vulnerability to malnutrition and food insecurity, children face the greatest risk for adverse health outcomes related to climate change. Vulnerability, however, is highly variable, with some children in food insecure communities showing healthy growth, while some children in food secure communities show signs of malnutrition. In West Africa, Burkina Faso faces high levels of child malnutrition, loses to farmland and a large share of the population have no access to clean water. Because the overwhelming majority of children rely on locally grown, rainfed agriculture and well/surface water, the combined impact of climate change and population growth decreases water availability and farmland per person. However, there is notable community and individual variation in malnutrition levels suggesting that there are important coping strategies that vulnerable families may use to secure their children's health. No spatially relevant analysis of water and food insecurity and children's health exists for Burkina Faso. The goal of this research is to identify and quantify the combined and inter-related impact of unsafe drinking water and community-level food availability on the physical health outcomes of Burkinabe children under five years of age. To accomplish this goal we rely on a publically available highly detailed, geo-referenced data set (Demographic and Health Survey (DHS)) to provide information on measures of childhood malnutrition and details on parental characteristics related to children's health. Information on water source (covered/uncovered well, piped water, etc.) and water quality (measures of arsenic and pollution) comes from DHS along with a recently collected geo-referenced US Agency for International Development (USAID) data set.

    The controversies surrounding transgenic crops, often called Genetically Modified Organisms (GMOs), call for a need to raise the level of public awareness of Genetic Modification (GM) technology in Africa. This should be accomplished by educating the public about the potential benefits and risks that may be associated with this new technology. In the last 15 years, GM crop producing countries have benefited from adoption of this new technology in the form of improved crop productivity, food security, and quality of life. The increased income to resource-poor farmers is a key benefit at the individual level especially as most countries using this technology are in the developing world, including three African countries (South Africa, Burkina Faso and Egypt). Despite clear benefits to countries and farmers who grow GMOs, many people are concerned about suspected potential risks associated with GMOs. This sparks debate as to whether GM technology should be adopted or not. Given the concerns regarding the safety of GMO products, thorough scientific investigation of safe application of GMOs is required. The objective of this paper is to respond to the issues of GM agriculture in Africa and some of the issues surrounding the adoption of GM crops between developed and developing countries. In this article, I analyse relevant papers relating to the adoption of GM technology particularly in developing countries including the few African countries that have adopted GM crops. The issues discussed span a wide range including: safety; potential benefits and risks; disputes between the United States of America (USA) and the European Union (EU) over adoption of GM crops with a focus on Africa continent. This article is concluded by summarising the issues raised and how GM technology can be adopted for agricultural development in Africa. PMID:21981823

    In many part of the Tropics the ground based gauge networks are sparse, often degrading and accessing this data for monitoring rainfall or for validating satellite products is sometime difficult. Here, an alternative rainfall measuring technique is proposed and tested in West Africa. It is based on using commercial microwave links from cellular telephone networks to detect and quantify rainfall. Rainfall monitoring based on commercial terrestrial microwave links has been tested for the first time in Burkina Faso, in Sahel. The rainfall regime is characterized by intense rainfall intensities brought by mesoscale Convective systems (MCS), generated by deep organized convection. The region is subjected to drought as well as dramatic floods associated with the intense rainfall provided by a few MCSs. The hydrometeorological risk is increasing and need to be monitored. In collaboration with the national cellular phone operator, Telecel Faso, the attenuation on 29 km long microwave links operating at 7 GHz was monitored at 1s time rate for the monsoon season 2012. The time series of attenuation is transformed into rain rates and compared with rain gauge data. The method is successful in quantifying rainfall: 95% of the rainy days are detected. The correlation with the daily raingauge series is 0.8 and the season bias is 5%. The correlation at the 5 min time step within each event is also high. We will present the quantitative results, discuss the uncertainties and compare the time series and the 2D maps with those derived from a polarimetric radar. The results demonstrate the potential interest of exploiting national and regional wireless telecommunication networks to provide rainfall maps for various applications : urban hydrology, agro-hydrological risk monitoring, satellite validation and development of combined rainfall products. We will also present the outcome of the first international Rain Cell Africa workshop held in Ouagadougou early 2015.

    The use of information and communication technologies (ICT) tools to improve the efficiency of professionalism at work is increasing every time under the dynamic digital environment. Tools such as telemedicine, tele-education, and health informatics have of late been incorporated in the health sector to enable easy access to essential services, for example, in medical areas from referral centers by the patients on one hand and enabling the doctor to doctor consultations for the benefit of patients. Unfortunately, observations indicate dearth efforts and commitment to optimize use of the tools in the majority of the countries south of the Sahara. Sub-Saharan Africa has been left almost behind the rest of the world in terms of development going through decades of economic exploitation by especially the west through its natural and human resources. These factors, ethnic conflicts and endless wars have continued to ruin sub-Saharan Africa's socio-economic development. Information was obtained through a network of telemedicine practitioners in different African countries using internet communication, through E-mail and reviewing existing literature of their activities. This information was compiled from representative countries in each African region and the previous authors'experiences as telemedicine practioners. Most of these countries have inadequate ICT infrastructure, which yet creates sub-optimal application. Sub-Saharan Africa, made up of 33 of the 48 global poorest countries has to extend its ICT diffusion and policy to match the ever developing global economy. In some countries such as Ethiopia and South Africa there is significant progress in Telemedicine while in countries such as Burkina Faso and Nigeria the progress is slow because of lack of political support. Almost all reference to Africa is made in due respect to sub-Saharan Africa, one with big social, economic, and political problems with resultant high morbidity and mortality rates. This also

Information was obtained through a network of telemedicine practitioners in different African countries using internet communication, through E-mail and reviewing existing literature of their activities. This information was compiled from representative countries in each African region and the previous authors’experiences as telemedicine practioners. Most of these countries have inadequate ICT infrastructure, which yet creates sub-optimal application. Sub-Saharan Africa, made up of 33 of the 48 global poorest countries has to extend its ICT diffusion and policy to match the ever developing global economy. In some countries such as Ethiopia and South Africa there is significant progress in Telemedicine while in countries such as Burkina Faso and Nigeria the progress is slow because of lack of political support. Almost all reference to Africa is made in due respect to sub-Saharan Africa, one with big social, economic, and political problems with resultant high morbidity and mortality rates. This also

    This research on user fee removal in three African countries is located at the interface of public policy analysis and health systems research. Public policy analysis has gradually become a vast and multifaceted area of research consisting of a number of perspectives. But the context of public policies in Sahelian Africa has some specific characteristics. They are largely shaped by international institutions and development agencies, on the basis of very common 'one-size-fits-all' models; the practical norms that govern the actual behaviour of employees are far removed from official norms; public goods and services are co-delivered by a string of different actors and institutions, with little coordination between them; the State is widely regarded by the majority of citizens as untrustworthy. In such a context, setting up and implementing health user fee exemptions in Burkina Faso, Mali and Niger was beset by major problems, lack of coherence and bottlenecks that affect public policy-making and implementation in these countries.

    Environmental change in the Sudan-Sahel region of West Africa (SSWA) has been much debated since the droughts of the 1970s. In this article we assess climate variability and environmental stress in the region. Households in Senegal, Mali, Burkina Faso, Niger, and Nigeria were asked about climatic changes and their perceptions were compared across north-south and west-east rainfall gradients. More than 80% of all households found that rainfall had decreased, especially in the wettest areas. Increases in wind speeds and temperature were perceived by an overall 60-80% of households. Contrary to household perceptions, observed rainfall patterns showed an increasing trend over the past 20 years. However, August rainfall declined, and could therefore potentially explain the contrasting negative household perceptions of rainfall trends. Most households reported degradation of soils, water resources, vegetation, and fauna, but more so in the 500-900 mm zones. Adaptation measures to counter environmental degradation included use of manure, reforestation, soil and water conservation, and protection of fauna and vegetation. The results raise concerns for future environmental management in the region, especially in the 500-900 mm zones and the western part of SSWA.

    A putative driver of global amphibian decline is the panzootic chytrid fungus Batrachochytrium dendrobatidis (Bd). While Bd has been documented across continental Africa, its distribution in West Africa remains ambiguous. We tested 793 West African amphibians (one caecilian and 61 anuran species) for the presence of Bd. The samples originated from seven West African countries - Bénin, Burkina Faso, Côte d'Ivoire, Ghana, Guinea, Liberia, Sierra Leone - and were collected from a variety of habitats, ranging from lowland rainforests to montane forests, montane grasslands to humid and dry lowland savannahs. The species investigated comprised various life-history strategies, but we focused particularly on aquatic and riparian species. We used diagnostic PCR to screen 656 specimen swabs and histology to analyse 137 specimen toe tips. All samples tested negative for Bd, including a widespread habitat generalist Hoplobatrachus occipitalis which is intensively traded on the West African food market and thus could be a potential dispersal agent for Bd. Continental fine-grained (30 arc seconds) environmental niche models suggest that Bd should have a broad distribution across West Africa that includes most of the regions and habitats that we surveyed. The surprising apparent absence of Bd in West Africa indicates that the Dahomey Gap may have acted as a natural barrier. Herein we highlight the importance of this Bd-free region of the African continent - especially for the long-term conservation of several threatened species depending on fast flowing forest streams (Conraua alleni (“Vulnerable”) and Petropedetes natator (“Near Threatened”)) as well as the “Critically Endangered” viviparous toad endemic to the montane grasslands of Mount Nimba (Nimbaphrynoides occidentalis).

    Coercive experiences at sexual debut have been shown to be associated with other sexual risks throughout the life course. Using nationally representative surveys from 12–19 year old girls in Burkina Faso, Ghana, Malawi, and Uganda collected in 2004, we examine the prevalence of sexual coercion at sexual debut among unmarried girls and its correlates. In Malawi, 38 percent of girls said that they were “not willing at all” at their first sexual experience followed by Ghana at 30 percent, Uganda at 23 percent and Burkina Faso at 15 percent. In-depth interviews collected in 2003 with the same demographic shows that there are four primary types of sexual coercion: forced sex; pressure through money or gifts; flattery, pestering, and threatening to have sex with other girls; and passive acceptance. The article concludes with the research and policy implications of these findings. PMID:18458747

    Background: This study aimed to analysis the inequalities of mortality of children under 5 years in West Africa by examining the determinants and contributing factors to the overall inequality concentration in these countries. Method: Data used came from the DHS surveys conducted in the six countries in West Africa: Burkina Faso (2010), Benin (2006), Cote d’Ivoire 2011), Ghana (2008), Mali (2006), Nigeria (2008) and Niger (2012). The concentration index (CI) and Generalized Linear Model (GLM) with logit link were used to access inequality. Results: The results show that in all countries, the poorest Q1 have the highest proportions of deaths: Nigeria (31.4%), Cote d’Ivoire (30.4%) and Ghana (36.4%), over 30% of deaths of children under 5 years are among the children of the poorest (Q1) and the absolute differences of proportions Q1–Q5 are more than 20 points (25.8 in Ghana and 23.6 in Nigeria). The contributing factors of inequalities of child mortality were birth order, maternal age, parity and household size. Our findings also showed that the intensity of inequality varies from one country to another. Conclusion: The most important conclusion of this study is to reduce mortality in children under 5 years, it is needed to reduce economic and social inequalities and improve the country’s economic and social condition. There is a need for monitoring and assessment inequalities by leading causes of death and morbidity among children in the region in order to advance in understanding the gaps and finding a way to reduce them in West Africa countries.

    Background Malaria continues to be a major cause of infectious disease mortality in tropical regions. However, deaths from malaria are most often not individually documented, and as a result overall understanding of malaria epidemiology is inadequate. INDEPTH Network members maintain population surveillance in Health and Demographic Surveillance System sites across Africa and Asia, in which individual deaths are followed up with verbal autopsies. Objective To present patterns of malaria mortality determined by verbal autopsy from INDEPTH sites across Africa and Asia, comparing these findings with other relevant information on malaria in the same regions. Design From a database covering 111,910 deaths over 12,204,043 person-years in 22 sites, in which verbal autopsy data were handled according to the WHO 2012 standard and processed using the InterVA-4 model, over 6,000 deaths were attributed to malaria. The overall period covered was 1992–2012, but two-thirds of the observations related to 2006–2012. These deaths were analysed by site, time period, age group and sex to investigate epidemiological differences in malaria mortality. Results Rates of malaria mortality varied by 1:10,000 across the sites, with generally low rates in Asia (one site recording no malaria deaths over 0.5 million person-years) and some of the highest rates in West Africa (Nouna, Burkina Faso: 2.47 per 1,000 person-years). Childhood malaria mortality rates were strongly correlated with Malaria Atlas Project estimates of Plasmodium falciparum parasite rates for the same locations. Adult malaria mortality rates, while lower than corresponding childhood rates, were strongly correlated with childhood rates at the site level. Conclusions The wide variations observed in malaria mortality, which were nevertheless consistent with various other estimates, suggest that population-based registration of deaths using verbal autopsy is a useful approach to understanding the details of malaria

  15. Microsatellite analysis supports clonal propagation and reduced divergence of Trypanosoma vivax from asymptomatic to fatally infected livestock in South America compared to West Africa

    2014-01-01

    Background Mechanical transmission of the major livestock pathogen Trypanosoma vivax by other biting flies than tsetse allows its spread from Africa to the New World. Genetic studies are restricted to a small number of isolates and based on molecular markers that evolve too slowly to resolve the relationships between American and West African populations and, thus, unable us to uncover the recent history of T. vivax in the New World. Methods T. vivax genetic diversity, population structure and the source of outbreaks was investigated through the microsatellite multiloci (7 loci) genotype (MLGs) analysis in South America (47isolates from Brazil, Venezuela and French Guiana) and West Africa (12 isolates from The Gambia, Burkina Faso, Ghana, Benin and Nigeria). Relationships among MLGs were explored using phylogenetic, principal component and STRUCTURE analyses. Results Although closely phylogenetically related, for the first time, genetic differences were detected between T. vivax isolates from South America (11 genotypes/47 isolates) and West Africa (12 genotypes/12 isolates) with no MLGs in common. Diversity was far greater across West Africa than in South America, where genotypes from Brazil (MLG1-6), Venezuela (MLG7-10) and French Guiana (MLG11) shared similar but not identical allele composition. No MLG was exclusive to asymptomatic (endemic areas) or sick (outbreaks in non-endemic areas) animals, but only MLGs1, 2 and 3 were responsible for severe haematological and neurological disorders. Conclusions Our results revealed closely related genotypes of T. vivax in Brazil and Venezuela, regardless of endemicity and clinical conditions of the infected livestock. The MLGs analysis from T. vivax across SA and WA support clonal propagation, and is consistent with the hypothesis that the SA populations examined here derived from common ancestors recently introduced from West Africa. The molecular markers defined here are valuable to assess the genetic diversity, to

    Endemic and epidemic group A meningococcal meningitis remains a major cause of morbidity and mortality in sub-Saharan Africa, despite the availability of the safe and inexpensive group A meningococcal polysaccharide vaccine, which is protective at all ages when administered as directed. Despite optimal therapy, meningococcal meningitis has a 10% fatality rate and at least 15% central nervous system damage. WHO's policy of epidemic containment prevents, at best, about 50% of cases and ignores endemic meningitis, which is estimated at 50,000 cases per year. The effectiveness of group A, C, W135, and Y capsular polysaccharides is the basis for recommending universal vaccination with group A meningococcal polysaccharide twice in infancy, followed by the four-valent vaccine in children aged two and six years. This could eliminate epidemic and endemic disease, prepare for the use of conjugates when they become available, and probably could have prevented the recent epidemics of groups A and W135 meningitis in Burkina Faso.

    Peroxy radical measurements made on board the DLR-Falcon research aircraft over West Africa within the African Monsoon Multidisciplinary Analysis (AMMA) campaign during the 2006 wet monsoon are presented in this study. The analysis of data focuses on the photochemical activity of air masses sampled during episodes of intense convection and biomass burning. Generally, the total sum of peroxy radical mixing ratios, measured in the outflow of convective clouds, are quite variable but occasionally are coupled with the NO variations indicating the coexistence or simultaneous emission of NOx, with a potential radical precursor (i.e. formaldehyde, acetone or peroxides), which has likely been transported to higher atmospheric altitudes. Based on the measurements, significant O3 production rates around 1 ppb/h in the MCS outflow are estimated by using a box model with simplified chemistry. Peroxy radicals having mixing ratios around 20-25 pptv and with peak values of up to 60-70 pptv are measured within biomass burning plumes, detected at the coast in Ghana. Calculations of back-trajectory densities confirm the origin of these air masses being a biomass burning region at southern latitudes and close to the Gulf of Guinea, according to satellite pictures. Measured peroxy radical concentrations agree reasonably with modelled estimations taking into account simple local chemistry. Moreover, the vertical profiles taken at the aircraft base in Ouagadougou, Burkina Faso, indicate the common feature of having maximum concentrations between 2 and 4 km, in agreement with other literature values obtained under similar conditions.

    The Great Green Wall for the Sahara and the Sahel Initiative was launched to address the increasing challenges of land degradation, desertification and drought, climate change, food insecurity and poverty in more than 20 countries. Restoration of agro-sylvo-pastoral landscapes and degraded lands is one of the priority interventions initiated, enabling the springing up of green nests of life. When complete, the Great Green Wall of Africa will reverse the seemingly unstoppable desertification and address the development of its drylands' inhabitant rural communities. Today's planting of modest seedlings will grow into vast mosaics of forest and agroforestry landscapes and grasslands, which will provide essential ecosystem goods and services, restore lost livelihoods and create new wealth. The ambition of reforestation efforts within this initiative - the like of which the world has never seen before - sounds like an impossible dream. However, learning from past mistakes and capitalising on current advancement in science and technology, it is a reality that is taking root. Following a successful restoration model that RBG Kew experts have devised, we are helping to mobilise, train and support communities in four border regions in Burkina Faso, Mali and Niger. In collaboration with FAO, the Millennium Seed Bank Partnership is using its unique expertise to ensure that seeds of environmentally well-adapted and economically useful local species are collected and planted in communal gardens and village agroforestry systems managed by the communities themselves. In our first year, an estimated total of 162,000 seedlings and 61 kg of seeds from 40 useful native species, including grasses for livestock, have been planted to cover 237 ha of farmer-managed land in 19 villages. The keen interest it has created has indicated that these figures will rise five-fold in the second year. These green bricks are the foundations of the living wall that will eventually reach across the

    One of the most immediate and obvious impacts of climate change is on the weather-sensitive agriculture sector. Both local and global impacts on production of food will have a negative effect on the ability of humanity to meet its growing food demands. Agriculture has become more risky, particularly for farmers in the most vulnerable and food insecure regions of the world such as East Africa. Smallholders and low-income farmers need better financial tools to reduce the risk to food security while enabling productivity increases to meet the needs of a growing population. This paper will describe a recently funded project that brings together climate science, economics, and remote sensing expertise to focus on providing a scalable and sensor-independent remote sensing based product that can be used in developing regional rainfed agriculture insurance programs around the world. We will focus our efforts in Ethiopia and Kenya in East Africa and in Senegal and Burkina Faso in West Africa, where there are active index insurance pilots that can test the effectiveness of our remote sensing-based approach for use in the agriculture insurance industry. The paper will present the overall program, explain links to the insurance industry, and present comparisons of the four remote sensing datasets used to identify drought: the CHIRPS 30-year rainfall data product, the GIMMS 30-year vegetation data product from AVHRR, the ESA soil moisture ECV-30 year soil moisture data product, and a MODIS Evapotranspiration (ET) 15-year dataset. A summary of next year's plans for this project will be presented at the close of the presentation.

    2014-01-01

    Background Malaria control is based on early treatment of cases and on vector control. The current measures for malaria vector control in Africa are mainly based on long-lasting insecticide treated nets (LLINs) and to a much smaller extent on indoor residual spraying (IRS). A third pillar in the fight against the malaria vector, larval source management (LSM), has virtually not been used in Africa since the ban of DDT in the 1960s. Within the light of recent WHO recommendations for Bacillus thuringiensis israelensis (Bti) use against malaria and other vector species, larval source management could see a revival in the upcoming years. In this project we analyze the ecologic and health impacts as well as the cost effectiveness of larval source management under different larviciding scenarios in a health district in Burkina Faso. Methods The project is designed as prospective intervention study with duration of three years (2013–2015). Its spatial scale includes three arms of interventions and control, comprising a total of 127 villages and the district capital Nouna in the extended HDSS (Health Demographic Surveillance System) of the Kossi province. Baseline data on mosquito abundance, parasitemia in U5 children, and malaria related morbidity and mortality are gathered over the project duration. Besides the outcome on ecologic and health parameters, the economic costs are seized and valued against the achieved health benefits. Conclusions Risk map based, guided larvicide application might be a possibility to further decrease economic cost of LSM and facilitate its faster incorporation to integrated malaria control programs. Given the limited resources in many malaria endemic countries, it is of utmost importance to relate the costs of novel strategies for malaria prevention to their effect on the burden of the disease. Occurring costs and the impact on the health situation will be made comparable to other, existing intervention strategies, allowing stakeholders and

    Within the international momentum for achieving Education for All (EFA) and the Millennium Development Goals (MDGs), many African countries have made considerable progress during the last decade in terms of access to basic education. However, a significant number of children enrolled in the early grades of primary schools either repeat classes or drop out and never graduate. Moreover, there are currently about 30 million school-age children in sub-Saharan Africa who have never attended any form of schooling. In view of this situation, sub-Saharan African countries have been looking for alternative options to educate those who have not been accounted for in the formal school system. This note considers informal Koranic Education Centres (KECs) which are trying to fill the gap of schooling in the Sahel-Saharan strip. The author looks at the challenges this form of schooling faces and at how to meet them efficiently. He sounds out the possibility of using KECs to cater for those who have been left aside by formal schooling. Based on existing studies, data compiled by educational systems and a study conducted by the Working Group on Non-Formal Education (WGNFE) of the Association for the Development of Education in Africa (ADEA) in four West African countries (Burkina Faso, Mali, Mauritania and Senegal) in 2013, the author of this research note came to the conclusion that a holistic approach, where the two systems (the Koranic and the formal) collaborate and support one another, could effectively contribute to alleviating the dropout predicament and to reducing the number of unschooled children. It could offer a second-chance opportunity to dropout and unschooled children in the Sahel and Saharan zone. However, before this can become a viable alternative, a number of major challenges need to be addressed. Through its WGNFE, ADEA intends to further investigate the holistic approach of combining formal "modern" and informal "Koranic" schooling to come up with tangible

    Providing valuable forecasts of the seasonal precipitation amount for the upcoming rainy season is one of the big challenges for the national weather services in West Africa. Every year a harmonized forecast of the seasonal precipitation amount for the West African region is issued by the national weather services within the PRESAO framework. The PREASO forecast is based on various statistical approaches ranging from a simple subjective analog method based on the experiences of a meteorological expert to objective regression-based approaches by using various sources of input information such as predicted monsoon winds or observed sea surface temperature anomalies close to the West African coastline. The objective of this study is to perform an evaluation of these techniques for selected West African regions and to introduce classification techniques in the current operational practices and to combine these approaches with further techniques for an additional refinement of the forecasting procedure. We use a fuzzy-rule based technique for a classification of (sub-) monthly large-scale atmospheric and oceanic patterns which are combined to further statistical approaches such as an analog method and a data depth approach for the prediction of the (sub-) seasonal precipitation amounts and additional precipitation indices. The study regions are located from the Edges of the Sahel region in the North of Burkina Faso to the coastline of Ghana. A novel precipitation archive based on daily observations provided by the meteorological services of Burkina Faso and Ghana is the basis for the predictands and is used as reference for model evaluation. The performance of the approach is evaluated over a long period (e.g. 50 years) using cross-validation techniques and sophisticated verification measures for an evaluation of a probability forecast. The precipitation forecast of the classification techniques are also compared to the techniques of the PREASAO community, the

    The main aetiology of human arsenic toxicity provide from natural geological source. The characteristic skin lesions of arsenic toxicity may be used as an indicator of high exposure. We have registered 45 cases. The age bracket was one to 70 years. We have registered 27 women (60%) and 18 men (40%). The cutaneous manifestations have been dominated by the palmo plantar hyperkeratosis and hyperpigmentations (77,8% each one). The urinary concentrations of arsenic were 13 microg/l to 212 microg/l; they were 69 to 101 microg/l in the drinking water localized in the golden area, however they were normal outside this area. The clinical features were similar with the description of the literature. Intoxication of drinking water is problem of public health and we recommend checking all the other golden areas to find some appropriate solutions.

    Background Financial barriers are a recognized major bottleneck of access and use of health services. The aim of this study was to assess effectiveness of a community based health insurance (CBHI) scheme on utilization of health services as well as on mortality and morbidity. Methods Data were collected from April to December 2007 from the Nouna’s Demographic Surveillance System on overall mortality, utilization of health services, household characteristics, distance to health facilities, membership in the Nouna CBHI. We analyzed differentials in overall mortality and selected maternal health process measures between members and non-members of the insurance scheme. Results After adjusting for covariates there was no significant difference in overall mortality between households who could not have been members (because their area was yet to be covered by the stepped-wedged scheme), non-members but whose households could have been members (areas covered but not enrolled), and members of the insurance scheme. The risk of overall mortality increased significantly with distance to health facility (35% more outside Nouna town) and with education level (37% lower when at least primary school education achieved in households). Conclusion There was no statistically significant difference in overall mortality between members and non-members. The enrolment rates remain low, with selection bias. It is important that community based health insurances, exemptions fees policy and national health insurances be evaluated on prevention of deaths and severe morbidities instead of on drop-out rates, selection bias, adverse selection and catastrophic payments for health care only. Effective social protection will require national health insurance. PMID:23082967

    The aim of the study was to describe the bacterial microflora of diabetic foot infection and to identify the factors which determine the bacterial spectrum in order to increase empiric antibiotic prescription in Ouagadougou. The study was a cross-sectional one, carried from July 1st, 2011 to June 30, 2012 in the departments of internal medicine and general and digestive surgery in Yalgado Ouédraogo teaching hospital. Samples for bacteriological tests consisted of aspiration of pus through the healthy skin, curettage and swab of the base of the ulceration or tissue biopsy from foot lesions. The bacteria's sensitivity to antibiotics has been tested by the qualitative method (Kirby-Bauer). The frequency of diabetic foot infection was 14.45% and the monthly incidence 5.33. The mean age of patients was 56 years and the sex ratio 1.37. Foot ulcerations were chronic in 33 (51.56%), necrotic in 51 (79.69%) and associated with osteitis in 40 (62.5%) patients. Infection was grade 3 in 70.3% cases. Thirty-nine patients had received antibiotics before hospital admission. Among the 71 samples, 62 (87.32%) cultures were positive: 53 (85.48%) monomicrobial and 9 (14.52%) bimicrobial. Aerobic Gram-positive cocci (76%) were the most frequent from ulcerations: Staphylococcus aureus (32.39%), Streptococcus sp (18.30%). Negative coagulase staphylococci have been found in 23.94% cases. Aerobic gram-negative bacilli have been isolated from 24% ulcerations. No factor was associated with the type of bacteria. Gram-positive pathogen cocci showed a high sensitivity to amoxicillin-clavulanic acid and oxacillin. No methicillin-resistant Staphylococcus aureus (MRSA) or extended-spectrum beta lactamase Enterobacteriaceae (ESBL) have been isolated. A better design is necessary to a clarification of bacterial flora in diabetic foot infections. Prevention of bacterial resistance is also needed.

    High-risk human papillomavirus (HPV) is found in over 99% of cervical cancers. The aim of this study was to determine the prevalence of HPV in a population of women in Bobo-Dioulasso and to identify the high-risk types present in these women. From May to June, 2015, 181 women who came for consultation at the Souro Sanou University Hospital of Bobo-Dioulasso have been included in this study. Uterine endocervical swabs have been taken in these women. DNA obtained by extraction from the samples thus collected was used to determine the prevalence of high-risk human papillomavirus genotypes through real-time PCR. The age of the women ranged from 20 to 56 years with a mean of 35.3 ± 8.1 years. The prevalence of infection by high-risk HPV types was 25.4% (46/181). The most common high-risk HPV genotypes were HPV 39 (18.5%), HPV 52 (16.7%), HPV 18 (14.8%), and HPV 35 (13.0%). HPV 16 which is included in the HPV vaccines was not found in the population studied. This type of study which is the first one in Bobo-Dioulasso has showed a high prevalence of genotypes HPV 39, HPV 52, and HPV 35 which are not yet covered by a vaccine. PMID:27525275
