Zika virus (ZIKV) is a mosquito- borne flavivirus related to yellow fever virus, dengue virus (DENV), and West Nile virus (WNV). It is a single-strand- ed positive RNA virus (10,794-nt genome) that is closely related to the Spondweni virus and is transmitted by many Aedes spp. mosquitoes, including Ae. africanus, Ae. lu- teocephalus, Ae. hensilli, and Ae. aegypti. The virus was identified in rhesus monkeys during sylvatic yellow fever surveillance in the Zika Forest in Uganda in 1947 and was reported in humans in 1952.
