Incubation period for Zika virus

Zika symptoms may begin within several days after infection, although many infected people have no noticeable symptoms. The timing is an estimate, so feeling well soon after a mosquito bite does not establish that infection did or did not occur.

When symptoms occur, they may include a mild fever, an itchy rash, red eyes, joint pain, muscle pain, headache, or discomfort behind the eyes. These signs overlap with other travel-related infections. Zika can also spread through sexual contact, and infection during pregnancy can affect the developing fetus, making travel and pregnancy details important during assessment.

Record travel dates, the places visited, mosquito bites, sexual exposure, pregnancy status, and when symptoms started. Contact a GP Consultation for personalised advice, particularly if you are pregnant or planning pregnancy. Use insect repellent, long clothing, screens, and condoms as appropriate. A Travel Health Consultation can help with prevention before future journeys.

Arrange medical advice for a new rash, fever, red eyes, or joint pain after travel or possible exposure. Seek urgent help for severe headache, weakness, confusion, breathing difficulty, or neurological symptoms. Pregnancy, a partner who may have been exposed, or a destination with mosquito-borne infections warrants prompt discussion even without obvious symptoms.

Ask whether testing is appropriate, how long to use mosquito and sexual precautions, what pregnancy-related steps are needed, and which symptoms require urgent review.
