Zika virus (ZIKV) is a flavivirus related to yellow fever, dengue, West Nile, and Japanese encephalitis viruses; however, ZIKV produces a comparatively mild disease in humans. It was first isolated from an infected rhesus monkey in the Zika Forest of Uganda in 1947.

Until recently, it was relatively rare to see ZIKV outside of Africa and Asia. The virus is transmitted to humans via mosquitoes of the genus Aedes.

Symptoms may include a headache, a maculopapular rash covering the face, neck, trunk, and upper arms,which may spread to the palms and soles. Transient fever, malaise, and back pain may also develop.

In 2015 to date, 10 countries in Central and South America and Mexico have reported local transmission of Zika virus.
