摘要: Gabon, in Central Africa, was affected for the first time 2007 and then 2010 by simultaneous outbreaks of chikungunya Dengue serotype 2 (DENV-2) viruses. Through national surveillance dengue-like syndromes between 2010, we observed continuous circulation DENV-2 a southward movement. This rapid spread associated with emergence DENV-1 DENV-3 2010. Interestingly, detected six infected patients hemorrhagic signs during second outbreak Although these cases do not meet all standard WHO criteria severe hemorrhage (formerly DHF), this is report several dengue fever different DENV serotypes Africa. Together, findings suggest that becoming more widely established on continent DHF will likely become serious public-health problem near future.
