The Zika virus info graphic

Zika virus was first identified in Uganda in 1947 in rhesus monkeys by researchers monitoring yellow fever. The virus got its name from the Zika Forest in Uganda where it was first discovered. It is classified as a flavivirus, which puts it in the same family as yellow fever, West Nile, Japanese encephalitis viruses and dengue. According to the Brazilian Ministry of Health, Brazil saw 20 times more microcephaly cases in 2015 than usual, following the outbreak of Zika in the country that year.
