Effect of chikungunya, Mayaro and Una virus coinfection on vector competence of Aedes aegypti mosquitoes.

ABSTRACT: The mosquito-borne alphaviruses chikungunya (CHIKV), Mayaro (MAYV) and the lesser known Una (UNAV) are currently co-circulating in Latin America, sharing their geographical and ecological niche with the Aedes aegypti mosquito. The sylvatic MAYV cycle and the unknown cycle of UNAV could possibly spill over and become urban transmission cycles involving Ae. aegypti. Despite their potential impact on public health, we know little about arboviral coinfections in humans, animals or mosquitoes. Especially the effect of coinfections on transmission by Ae. aegypti mosquitoes is understudied. We investigated the vector competence of Ae. aegypti for single, dual, and triple exposures with UNAV, MAYV and CHIKV, provided simultaneously in an infectious blood meal. Mosquitoe
