What should you know about Zika countries?

Zika is associated with areas where the mosquitoes that can carry the virus are present, but the situation in a destination can change. A country name alone does not describe risk for every region, season, or traveller. Your route, time spent outdoors, accommodation, and dates of travel all help a clinician interpret exposure. Destination information is especially relevant before pregnancy or when symptoms develop after a trip.

Before leaving, obtain current destination-specific travel advice and plan bite prevention. Pack a suitable repellent, choose clothing that covers exposed skin, and consider how you will protect sleeping areas. After travel, note any fever, rash, red eyes, headache, or aching joints, along with their start date. Take those details to an appointment rather than trying to identify an illness from destination lists alone.

Seek prompt medical advice if you are pregnant, may be pregnant, are trying to conceive, or have a pregnant partner and have travelled to a potentially affected destination. Make an appointment for illness after travel even if symptoms seem mild. Get urgent help for breathing difficulty, confusion, fainting, severe headache, repeated vomiting, or inability to keep fluids down.

Ask whether the exact places and dates of your trip affect Zika assessment, whether testing is indicated, and what precautions are appropriate for sex and pregnancy planning. Mention previous mosquito-borne illness and all medicines you take.
