The Zika virus rarely leads to serious illness for the holder but it does cause several pregnancy defects, including microcephaly as well as other severe fetal brain defects.
Outbreaks have been reported in Africa, Southeast Asia and the Pacific Islands and it is said to have been seen in more than 50 countries.
A recent rise in the spread of Zika has led to a number of children being born with abnormally small heads.
In February, WHO declared the Zika virus as a Public Health Emergency of International Concern.
