Zika is a mosquito-borne infection caused by Zika virus, a member of the genus flavivirus and family Flaviviridae. Zika virus was first isolated from a monkey in the Zika forest in Uganda in 1947.
Following the 2015-16 outbreak in the Americas and Caribbean, Zika virus is now thought to be endemic in this region as well as in much of Africa and Asia.

PHE and the National Travel Health Network and Centre (NaTHNaC) have reviewed and updated their Zika travel and sexual transmission advice and have made changes to the risk ratings in some countries.
Travellers should use the Country Information Pages on the NaTHNaC website for up to date and detailed advice for those travelling to countries or areas affected by Zika virus. The CIP are also linked to each individual country from the A to Z country list.
Travel associated risks of Zika have been classified into 2 categories based on the current and potential epidemiological situation in order to ensure that travel advice is appropriate and proportionate.
Guidance for primary care and clinicians has been jointly developed by PHE, the Royal College of Obstetricians and Gynaecologists and Royal College of Midwives, and Health Protection Scotland.
Zika virus infection may present an increased risk for certain groups of the population, particularly pregnant women. Specific travel advice for women planning pregnancy or who are currently pregnant is available.
If a person acquires Zika abroad and becomes ill on their return to the UK, any public health risk to the wider population is negligible, as the mosquito that transmits the virus is not found in the UK.
