The 2016 Olympic and Paralympic Games (Games) will be hosted in Rio de Janeiro, Brazil during August–September 2016. As of June 30, 2016, CDC had issued Zika-related travel notices for 49 countries and U.S. territories, including Brazil. Mosquito-borne Zika virus transmission is expected to be low during the Games, because they will be held during the winter season in Brazil and cooler, drier temperatures generally reduce mosquito populations. This report provides a risk assessment for importation and sustained, local mosquito-borne transmission of Zika virus from travel to the Games.
