Zika virus (ZIKV) is a member of the virus family Flaviviridae.[3] It is spread by daytime-active Aedes mosquitoes, such as A. aegypti and A. albopictus.[3] Its name comes from the Zika Forest of Uganda, where the virus was first isolated in 1947.[4] Zika virus is related to the dengue, yellow fever, Japanese encephalitis, and West Nile viruses.[4] Since the 1950s, it has been known to occur within a narrow equatorial belt from Africa to Asia. From 2007 to 2016, the virus spread eastward, across the Pacific Ocean to the Americas, leading to the 2015–16 Zika virus epidemic.
