Resumo: Chikungunya virus (CHIKV) has caused recent, large epidemics on isl-s in the Indian Ocean, raising the possibility of more widespread CHIKV epidemics. Historically, CHIKV has been vectored by Aedes aegypti, but these outbreaks likely also involved Ae. albopictus. To examine the potential for an outbreak of CHIKV in Florida, we determined the susceptibility to CHIKV of F1 Ae. aegypti - Ae. albopictus from Florida. In addition, we also evaluated two well-characterized laboratory strains (Rockefeller - Lake Charles) of these species. We determined infection - dissemination rates as well as total body titer of mosquitoes 7 days post-exposure (pe) (Ae. albopictus) - 3, 7, - 10 days pe (Ae. aegypti). All mosquito strains were susceptible to both infection - dissemination, with some variation between strains. Our results suggest Florida would be vulnerable to transmission of CHIKV in urban - rural areas where the two vector species occur.
