Abstract
Aedes-borne viruses, yellow fever (YF), dengue, Chikungunya and Zika are taking a huge toll on global health as Africa faces re-emergence with potential for massive human catastrophe. Transmission driven by diverse vectors in ecological settings that range from urban to rural and sylvatic habitats with human and nonhuman primate/reservoir activities across such habitats hasfacilitated virus movement and spillover to susceptible human populations. Approved vaccine exists for YF, although availability for routine and mass vaccination is often constrained. Integrating vector surveillance, understanding disease ecology with rationalised vaccination in high-risk areas (YF) remains important in disease prevention and control. We review trends in disease occurrence in Africa, hinting on gaps in disease detection and management and the prospects for prevention and/or control.
