Zika Virus (ZIKV) Infection: Recommendations for travelers, before / after travel

What is Zika Virus (ZIKV)?

The zika virus, a flavivirus spread by mosquitoes, was initially discovered in Uganda in 1947 in monkeys. Later, in 1952, it was discovered in people in the United Republic of Tanzania and Uganda.

People are typically exposed to the zika virus through the bite of infected Aedes mosquitoes, which primarily bite during the day and early at night.

Zika virus outbreaks have been reported in Asia, the Pacific, the Americas, Africa, and the African continent. Rare sporadic human infections were discovered in Africa and Asia during the 1960s and 1980s; these infections were often followed by a minor sickness.
