At the International Congress of Entomology’s annual meeting in Orlando, separate labs presented unpublished data suggesting that Culex mosquitoes can harbor the Zika virus. UTMB researchers shared unpublished data last month shared data suggesting that Culex mosquitoes in the U.S. do not transmit Zika virus. “Geographic populations of mosquito species can vary in their ability to transmit viruses like Zika, so we cannot be sure that Culex mosquitoes in other regions of the world are equally refractory to Zika virus infection,” a UTMB press release stated.
