Anopheles albimanus is a Potential Alphavirus Vector in the Americas.

ABSTRACT: Despite its ecological flexibility and geographical co-occurrence with human pathogens, little is known about the ability of Anopheles albimanus to transmit arboviruses. To address this gap, we challenged An. albimanus females with four alphaviruses and one flavivirus and monitored the progression of infections. We found this species is an efficient vector of the alphaviruses Mayaro virus, O'nyong-nyong virus, and Sindbis virus, although the latter two do not currently exist in its habitat range. An. albimanus was able to become infected with Chikungunya virus, but virus dissemination was rare (indicating the presence of a midgut escape barrier), and no mosquito transmitted. Mayaro virus rapidly established disseminated infections in An. albimanus females and was detected in the saliva of
