Countries with current or recent local transmission of Zika virus*^
Country Transmission status#

* Criteria for current or recent local transmission include reporting of local transmission by the country through the WHO or other official channels, clusters of travel related infection acquired in that country in travellers returning to other countries, or a declaration by the WHO of local transmission occurring in the country. Current or recent transmission is further defined as where the case(s) have onset dates within the past three months. There may be differences in the countries that are included between this list and others due to the assessment criteria.

Countries where there the only local transmission is sexual or intra-uterine/perinatal transmission (and not mosquito-borne) are not included.

^ The mosquitoes that spread Zika usually do not live at elevations above 2,000 metres. The risk of mosquito borne transmission in such areas of high elevation within a country (where present) is minimal. For more information, refer to the MMWR journal (

# The transmission status is based on the number of reported locally acquired confirmed cases, the number of affected areas in the country and the duration of the circulation.

Countries with evidence of past circulation or past outbreaks of Zika

It should be noted that the list of countries where Zika has occurred in the past may be much wider than those listed below, including tropical Africa, Asia and the Pacific Islands.  Zika may occur in other countries where there are suitable species of mosquitoes that can transmit the virus.

Pacific Islands

Historically, the first documented outbreak of Zika virus in the South Pacific occurred on Yap Island in the Federated States of Micronesia in 2007. In October 2013, French Polynesia reported its first outbreak, which then spread to other Pacific Islands.

Further cases of Zika may be reported from other nearby countries where there are suitable species of mosquitoes that can transmit the virus.

  • Cook Islands
  • Fiji
  • French Polynesia
  • Micronesia
  • New Caledonia
  • Papua New Guinea
  • Solomon Islands
  • Vanuatu

Elsewhere in the world

For a list of countries where there has been any evidence of past circulation, refer to the Bulletin World Health Organization, at the WHO website  (
