Zika virus is the virus that causes the infection known as zika fever or zika virus disease. The virus is a member of the Flaviviridae virus family and the genus Flavivirus.

The zika virus is related to the yellow fever, dengue, West Nile and the Japanese encephalitis viruses. The zika virus, because it is a Flavivirus, is icosahedral and enveloped. It has a single-stranded and non-segmented, positive-sense RNA genome. It belongs to the Spondweni serogroup.
