Zika virus (ZIKV) is transmitted by daytime biting mosquitoes and is similar to dengue fever. Symptoms include rash, conjunctivitis, muscle or joint pain. Neurological complications have been reported. There is consensus that ZIKV infection during pregnancy may cause some birth defects such as microcephaly. There is a low risk of sexual transmission of the disease. Countries/territories/areas with active or past Zika transmission have now been classified into 4 risk categories: high, moderate, low and very low, based on the current and potential epidemiological situation. These categories ensure travel advice is appropriate and proportionate to the defined ZIKV transmission risk.See current national advice for more details, including that for pregnant travellers, who are advised to postpone non-essential travel to high risk countries and also regarding condom use for preventing sexual transmission of the disease.
