Zika Fever History

The Zika virus was first isolated in 1947 in the Zika forest in Uganda (Africa). Since then, it has been found mainly in Africa and has caused small, sporadic outbreaks in Asia as well.

In 2007, a large epidemic was described on the Island of Yap (Micronesia), where about 75% of the population was infected.

During 2014, Chile notified the WHO of indigenous transmission of Zika virus fever on Easter Island. Then, in May 2015, the public health authorities of Brazil confirmed the transmission of the Zika virus.
