Zika virus is a mosquito-borne flavivirus that was first identified in macaques (Uganda, 1947). Later, in 1952, the virus was identified as a human virus in Uganda and the United Republic of Tanzania.
Disease outbreaks of this virus have been recorded in Africa, the Americas, Asia and the Pacific. Rare sporadic human infections were detected in Africa and Asia between the 1960s and 1980s, usually accompanied by mild symptoms.
The estimated incubation period (time elapsed between exposure and the onset of symptoms) of Zika virus is 3 to 14 days. Most infected people are asymptomatic. Symptoms, usually mild and lasting 2 to 7 days, consist of fever, rashes, conjunctivitis, muscle and joint pain, malaise and headache.
