Zika virus: country specific risk
Countries or areas with current or past Zika transmission have been classified into one of two risk ratings.
Latest update
Zika virus risk rating for countries, territories or areas
Countries or areas with current or past Zika virus transmission have been given 1 of 2 risk ratings (risk or very low risk) based on Zika virus epidemiology and risk to UK travellers. The greatest likelihood of acquiring Zika virus infection is in a country with risk, however, the individual risk of infection is likely to be lower if mosquito bite avoidance measures are followed.
An A to Z list of countries and areas and their Zika virus risk ratings is available.
Countries that have never reported Zika virus transmission are not listed in the A to Z list.
There is no specific travel advice for countries with presence of the mosquito vector and close proximity to countries that have reported Zika transmission but with no evidence of Zika virus. Other vector borne diseases may be present in these countries so appropriate precautions should be taken. Further advice regarding travel to these countries is available from the NaTHNaC country information pages.
To produce the country or area risk ratings, the UK uses data from the World Health Organization (WHO ), the European Centre for Disease Control (ECDC ), US Centers for Disease Control and Prevention, and epidemic intelligence systematically collected by PHE and NaTHNaC . This information is reviewed on a regular basis and the A to Z list updated as required.
The rationale and criteria for classifying the Zika risk for countries or areas in the A to Z list is available on the NaTHNaC website. Risk countries include those where there is evidence of current or recent outbreaks with significant transmission, new introduction or re-introduction of Zika virus or endemic transmission. Very low risk countries have interrupted transmission and a potential for future transmission.
A to Z of countries
To determine the Zika risk for a country or area of travel, use the A to Z and follow the links to country specific travel advice from NaTHNaC .
This list will be subject to change as the Zika virus outbreak situation in each area continues to evolve. It is strongly advised to continuously refer back to this list (which will be kept updated) and not rely on printed copies.
