Zika vírus (ZIKV) has caused a major epidemic in Brazil and several American countries. ZIKV is an arbovirus whose natural vectors during epidemics have been poorly determined. In this study, 1,683 mosquitoes collected in the vicinity of ZIKV suspected cases in Rio de Janeiro, Brazil, from June 2015 to July 2016 were screened for natural infection by molecular methods. Three pools of Aedes aegypti were found with ZIKV genomes. None of the examined Aedes albopictus and Culex quinquefasciatus were positive. This is the first report of natural infection by ZIKV in mosquitoes in Brazil and South America.
