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 to 2016 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.

Zika and pregnancy

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.

UK risk assessment

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.
