Description
Summary:The sub-Saharan African region is increasingly becoming urbanized with the creation of an urban ecology that is conducive to the emergence of vector-borne diseases, such as Aedes-borne viral infections. Aedes-borne viral infections pose a threat to urban health in sub-Saharan Africa. The major menacing arbovirus diseases in sub-Saharan Africa include dengue, yellow fever, chikungunya, and Zika, since they have shown (re)emergence in the last decades. In this review, we analyzed the risk factors for the resurgence of these arboviral diseases as well as their epidemiology and burden by studying the literature. The results suggested that the risk of emergence of Aedes-borne viral infections was related to the urbanicity and competence of Aedes, the genetics of these viruses, environmental factors, and the socio-economic conditions of the sub-Saharan population in urban areas. Better public health awareness and appropriate epidemiological and vector surveillance are essential.
