Ecology of arboviruses and their potential mosquito vectors in Benin, Côte d’Ivoire and Gabon: a mini review

Résumé

Mosquito-borne arboviral zoonoses are an increasingly (re-)emerging threat for millions of people in endemic countries of Africa. Aedes-transmitted yellow fever (YF), dengue (DEN), chikungunya (CHIK), and Zika (ZIK) viruses, as well as Aedes- and Culex transmitted Rift Valley fever virus (RVFV) infections often go undiagnosed and as a result, accurate clinical reports for these viral diseases are lacking. The absence of evidence-based risk maps for arbovirus infections hinders the implementation of more suitable prevention/surveillance and control strategies in both non-endemic and endemic African countries. The vectorial capacity of arbovirus-transmitting vectors is highly complex mainly due to the interplay between biotic and abiotic factors that vary in time and space, explaining the differential patterns of arbovirus diseases between countries. Mapping the influential factors of arbovirus transmission, such as vector ecology, behavior, and biology in countries with different outcomes of arboviral diseases, will strongly help improve our understanding of local epidemiology and circulation of these diseases. Herein, we review up-to-date data on the distribution of arboviruses and their respective vectors from three sub-Saharan African countries (Benin, Côte d’Ivoire, and Gabon) presenting different patterns of arbovirus diseases. We pinpointed major knowledge gaps and potential research interests to increase knowledge of the distribution of arboviral diseases and their vectors through African countries to improve the strategies to successfully prevent, monitor, and control the disease outbreak.
