Vector Competence Matrix of Aedes Mosquitoes and Arboviruses in Africa
Ecological, biological, and epidemiological synthesis
Virus	Aedes species	Key competence drivers	African evidence
Dengue virus	Aedes aegypti	Strong anthropophily; urban container breeding; temperature-sensitive replication	Urban outbreaks across West and East Africa; burden underestimated by limited diagnostics
Dengue virus	Aedes albopictus	Ecological plasticity; invasive spread; broad thermal tolerance	Emerging role in Central and West African dengue outbreaks
Chikungunya virus	Aedes aegypti	Efficient human–vector contact; aggressive daytime biting	Major East African outbreaks with rapid amplification
Chikungunya virus	Aedes albopictus	Enhanced competence for some genotypes; peri-urban adaptation	Outbreak intensification following species invasion
Zika virus	Aedes aegypti	Urban adaptation; immune–virus interactions	Evidence of cryptic circulation from serological studies
Yellow fever virus	Aedes aegypti	Efficient urban transmission; outbreak-driven amplification	Recurrent outbreaks despite vaccination campaigns
