Zika virus was first described in a captive sentinel febrile rhesus monkey in the Zika forest of Entebbe, Uganda in 1947. In 1948, the virus was recovered from the mosquito Aedes africanus in the Zika forest. The first human case was reported shortly thereafter in 1952. [1, 3]  Zika virus is widely distributed outside of Africa. Outbreaks have been described in Micronesia and French Polynesia. [4, 5]  A large outbreak of Zika was declared in the Americas in 2015-2016 that later spread mostly via travel to US states. In February 2016, the World Health Organization (WHO) declared the spread of Zika virus a public health emergency. [6]  Since 2017, Zika cases have declined, and as of January 2021, no countries in the world report active Zika virus infection outbreaks. [7]
