What should you know about Zika virus affected areas?

Zika is carried mainly by Aedes mosquitoes, which are present in many warm areas. The presence of these mosquitoes does not by itself confirm active Zika transmission. Local outbreaks and public-health advice can change, so an old travel blog or a friend’s previous experience may not reflect the current situation. Your actual exposure also depends on where you stay, time spent outdoors, mosquito protection and whether a sexual partner has travelled.

Check official destination-specific travel health information shortly before you leave and again if plans change. Pack an effective insect repellent, light clothing that covers skin, and items that help keep mosquitoes out of your room. Consider accommodation with screens or air conditioning. If pregnancy is planned, possible or established, seek individual advice before travel; decisions may involve both the traveller and their partner.

Contact a clinician if you feel unwell after travel, especially with fever, rash, red eyes, headache or joint pain. Arrange prompt advice if you are pregnant or planning pregnancy after travel to an area with possible Zika transmission. Get urgent help for severe headache, weakness, confusion, breathing difficulty, persistent vomiting, unusual bleeding or signs of dehydration. Tell the clinician where and when you travelled.

Ask how your destination and travel dates affect your risk, whether any tests could be useful, and how to reduce mosquito and sexual transmission risk. If you are planning a family, ask how your own travel and your partner’s travel should be considered.
