Epidemiology of dengue fever in Gabon: Results from a health facility-based fever surveillance in Lambarene and its surroundings.

ABSTRACT:

Background

In Africa, information on dengue is limited to outbreak reports and focused on some countries with continuing transmission in West and East Africa. To estimate the proportion of dengue-positive cases among febrile patients and identify clinical indicators of dengue cases, we conducted passive facility-based fever surveillance in a catchment area population of 70,000 residents of Lambaréné and its surroundings in Gabon.
