full_question: This virus is a member of the Flaviviridae family and is most closely related to the Spondweni virus. It was first isolated in a rhesus macaque in Uganda in 1947. In both humans and monkeys it is transmitted primarily by Aedes aegypti, though it can also be spread through sex, blood transfusions, and mother-to-child transmission. The latter can lead to chorioretinal scarring and microcephaly. An outbreak of this disease in 2015-2016 raised concerns about athletes competing in the Olympics. For 10 points, identify this mosquito-borne virus that caused a sharp drop in tourism to Brazil and the Caribbean.
