Abstract

Zika virus (ZIKV) is widely distributed in Brazil, with the Northeastern region (NE) the  most affected zone with the highest incidence of microcephaly associated with ZIKV  congenital infections. We report attempts to infect three populations of Cx. quinquefasciatus from severely affected sites from NE and Southeast (SE) regions of Brazil with three strains of ZIKV isolated from these localities. An Ae. aegypti  population from SE, was used as a positive control. All tested Cx. quinquefasciatus populations were refractory to the ZIKV isolates. There is still no reason to consider Cx. quinquefasciatus as a potential vector of ZIKV in Brazil.
