Zika virus, like other flviviruses, is transmitted by mosquitoes, primarily of the Aedes (Stegomyia) genus. Several Aedes spp. have been implicated, including Ae. aegypti, Ae. africanus, Ae. hensilli, and Ae. albopictus. The Ae.aegypti mosquito appears to be the major vector in Asia and was the suspected primary vector for the French Polynesia outbreak .
