Answer

The epidemiology of dengue fever in Africa is more poorly characterized. Aedes aegypti is present in a large portion of the Middle East and sub-Saharan Africa. Dengue fever is present in 19 countries on the African continent. In a 1993 epidemic in the Comoros, an estimated 60,000 persons were infected with dengue. Of note, no major dengue hemorrhagic fever epidemics have occurred in Africa, despite the fact that all 4 dengue serotypes circulate in the continent. This may be explained by a genetic factor in these populations.
