While it seems likely that dengue fever (DF) has existed in French Guiana for at least one century, data on outbreaks are sketchy before temporary eradication of the dengue vector mosquito Aedes aegypti and its reestablishment in the early 1960s. Dengue cases were serologically confirmed for the first time in 1965, ...

BackgroundDengue infection has been an important and serious public health concern in Malaysia ever since its first reported case here in 1902. Nevertheless, to our knowledge, no nationwide investigation has been carried out to determine the actual magnitude of dengue endemicity in the Malaysian population. In this study, we describe a cross sectional ...
BackgroundDuring the last decades, dengue viruses have spread throughout the Americas region, with an increase in the number of severe forms of dengue. The surveillance system in Guadeloupe (French West Indies) is currently operational for the detection of early outbreaks of dengue. The goal of the study was to ...
Objective? To assess the economic cost of routine Aedes aegypti control in an at-risk environment without dengue endemicity and the incremental costs incurred during a sporadic outbreak. Methods? The study was conducted in 2006 in the city of Guantanamo, Cuba. We took a societal perspective to calculate costs in months without dengue ...
During 2003, the Indian capital metropolis of Delhi was afflicted with an outbreak of dengue. A private-sector tertiary care hospital responded instantly to the sudden influx of 162 patients during an 8-week interval. That was an unusual challenge because, until 1997, the hospital had exclusively managed patients with ophthalmic disorders. ...
The Indian Subcontinent has emerged as a scene of many mosquito-borne infectious diseases, including malaria and dengue fever. After the 1990s, the rate of malaria declined owing largely to preventive measures, but at the same time dengue fever (DF) and dengue hemorrhagic fever (DHF) were increasing in the region. ...

BackgroundDengue infection spread in naive populations occurs in an explosive and widespread fashion primarily due to the absence of population herd immunity, the population dynamics and dispersal of Ae. aegypti, and the movement of individuals within the urban space. Knowledge on the relative contribution of such factors to the spatial dimension of dengue ...
Despite tremendous efforts by public health organizations in dengue-endemic countries, it has proven difficult to achieve effective and sustainable control of the primary dengue virus vector Aedes aegypti (L.) and to effectively disrupt dengue outbreaks. This problem has multiple root causes, including uncontrolled ...

In recent years, dengue viruses (serotypes 1 to 4) have spread throughout tropical regions worldwide. In many places, multiple dengue virus serotypes are circulating concurrently, which may increase the risk for the more severe form of the disease, dengue hemorrhagic fever. For the control and prevention of ...

SUMMARYNotified cases of dengue infections in Singapore reached historical highs in 2004 (9459 cases) and 2005 (13 817 cases) and the reason for such an increase is still to be established. We apply a mathematical model for dengue infection that takes into account the seasonal variation in incidence, characteristic of dengue fever, and ...
Dengue reemerged in Mauritius in 2009 after an absence of >30 years, and >200 cases were confirmed serologically. Molecular studies showed that the outbreak was caused by dengue virus type 2. Phylogenetic analysis of the envelope gene identified 2 clades of the virus. No case of hemorrhagic fever was recorded. PMID:20350397

Chapter overview Many mosquito-borne diseases were under surveillance in Queensland during the period 2002� 2006. Of these, Ross River virus (RRV) infection, Barmah Forest virus (BFV) infection, dengue and malaria were the most commonly reported. While the morbidity associated with these diseases is significant, among the 15,404 notifications of all mosquito-borne disease ...
Early and accurate diagnosis of dengue is imperative for disease surveillance, which helps in the control of dengue in endemic countries.

Aedes albopictus (Tiger mosquito) lives mostly in urban areas. The females lay their eggs in containers close to the stagnant water. Aedes albopictus is spreading worldwide, helped by international transports of tires. In metropolitan France, it has settled down in the French Riviera since 2004, in Corsica since 2006. It is also present in other Mediterranean countries like Italy and Spain. Since ...
During the month of June 2009, Mauritius experienced a short-lived outbreak of dengue fever localised in its capital city Port Louis. Aedes albopictus, a secondary vector of dengue viruses, was the probable vector. We introduce a method which combines Google Earth images, stochastic cellular automata and scale free network ideas to map ...
Dengue and dengue hemorrhagic fever re-emerged in Bangladesh in 2000 and 2001 and nearly all viruses isolated were dengue type 3. Phylogenetic analyses of the envelope genes of examples of these viruses indicated that they were most closely related to recently emerged dengue type 3 viruses from neighboring Thailand ...
In Singapore, after a major outbreak of dengue in 2005, another outbreak occurred in 2007. Laboratory-based surveillance detected a switch from dengue virus serotype 1 (DENV-1) to DENV-2. Phylogenetic analysis showed a clade replacement within DENV-2 cosmopolitan genotype, which accompanied the predominant serotype ...
