Emerg Infect Dis. 2017 Aug;23(8):1411-1412. doi: 10.3201/eid2308.162007. Epub 2017 Aug 15.


During 2014-2016, we conducted mosquito-based Zika virus surveillance in Rio de Janeiro, Brazil. Results suggest that Zika virus was probably introduced into the area during May-November 2013 via multiple in-country sources. Furthermore, our results strengthen the hypothesis that Zika virus in the Americas originated in Brazil during October 2012-May 2013.
