ZIKAV, an arthropod-borne virus (arbovirus) belonging to the family Flaviviridae and genus Flavivirus , was first isolated in 1947 from a monkey in the Zika forest, Uganda . Sporadic human Zika fever cases have been reported since the 1960s . The first documented outbreak outside Africa and Asia occurred in 2007 in the Yap State, Micronesia, in the North Pacific, where Zika fever was characterised by rash, conjunctivitis and arthralgia . ZIKAV has been isolated from several Aedes mosquito species, notably including Ae. aegypti  and Ae. albopictus . Ae. aegypti is widespread in the tropical and subtropical regions of the world and Ae. albopictus is now established in many parts of Europe, especially Mediterranean countries . Recent reports of imported cases of ZIKAV infection from south-east Asia or the Pacific to Europe  or Japan  highlight the risk of ZIKAV emergence in parts of the world where the vector is present.
