Zika and infected mosquito bites

The mosquitoes linked with Zika tend to bite during daylight as well as around dawn and dusk. A person may have no symptoms, or may develop fever, rash, joint aches, red eyes, headache, or muscle pain. These symptoms overlap with other infections, so a mosquito bite alone cannot identify the cause. Zika infection deserves particular attention around pregnancy because infection can affect a developing baby.

Before and during travel, use an insect repellent suitable for you, wear clothing that covers exposed skin, and keep accommodation screened or air-conditioned where possible. Remove or cover standing water near where you are staying because mosquitoes can breed there. If you develop symptoms after travel, note the countries visited and the dates of travel. A travel-health appointment can tailor prevention advice to your route and pregnancy plans.

Arrange prompt medical advice if you are pregnant or planning pregnancy and have travelled to an area with Zika transmission, especially after a mosquito bite or illness. Seek urgent assessment for severe headache, confusion, weakness, breathing difficulty, persistent vomiting, or signs of dehydration. Tell the clinician about recent travel, symptoms, pregnancy status, and any sexual exposure that may be relevant.

Ask whether your destination creates a Zika concern, which bite-prevention products fit your circumstances, and whether testing is appropriate after your travel or symptoms. If pregnancy is relevant, ask about protecting yourself and your partner from sexual transmission.
