Zika virus is an enveloped, single-stranded RNA virus that belongs to the flavivirus genre. As with arbovirus, it is transmitted by arthropods (mosquitoes), both Aedes aegypti (urban) and albopictus (rural). Zika virus was first isolated in 1947 from monkeys in Uganda. The first human cases were reported in 1952 in East Africa. Outbreaks were reported in Micronesia (2007), Polynesia (2013), and Chile (2014). Both diagnostic procedures and therapeutics are poorly developed. Serological tests cross-react with dengue and there are neither specific antivirals nor vaccines.
