French Guiana

In the present study, dengue and malaria co-infection clinical picture seems to be more severe than single infections in French Guiana, with a greater risk of deep thrombocytopaenia and anaemia.

Our results strongly support a role of illegal mining activities in the emergence of new foci of malaria.

A land-cover map, the hydrological network and the geolocalised inhabited houses were used to characterise the peridomestic landscape in eleven discoid buffers with radii of 50, 100, 200, 300, 400, 500, 600, 700, 800, 900 and 1000 metres.

We obtained health surveillance epidemiologic data on malaria among French military personnel deployed to French Guiana during 1998–2008. Incidence of Plasmodium vivax malaria increased and that of P. falciparum remained stable.

Although there is a statistical link, the predictive value of ENSO to modulate prevention intervention seems marginal in French Guiana.

In French Guiana, malaria transmission is mainly due to Anopheles darlingi Root, but other species also are involved. Investigation and surveillance must be carried out on all the species to unravel malaria transmission patterns.

With an Annual Parasite Incidence (API) of 132.1, in the high and moderate risks zones, French Guiana has the second highest malaria incidence of South-America after Guyana (API=183.54) and far above Brazil (API=28.25). For the first time in the past 40 years, the mosquito bionomics was related to the malaria transmission patterns in French Guiana.

The border area between Suriname and French Guiana is considered the most affected malaria area in South America. A one-year cooperative malaria vector study was performed by the two countries, between March 2004 and February 2005, in four villages.

Should the Kalimbe (a traditional Amerindian loincloth) be banned, based on its association with an increased risk of malaria?
