What should you know about chikungunya zika?

Chikungunya and Zika are mosquito-borne viruses with overlapping symptoms, so exposure history and clinical assessment help distinguish them. Chikungunya is particularly associated with prominent joint pain, while Zika may be milder and can include rash, red eyes and joint discomfort. Symptoms alone cannot reliably identify which virus is present.

Both infections can cause [Fever](/symptoms/fever/), tiredness, headache and muscle aches after mosquito exposure. Chikungunya often draws attention because joint pain can be intense or continue after the early illness. Zika matters especially in pregnancy because infection can affect an unborn baby, so pregnancy or plans to become pregnant should be mentioned promptly. Local transmission patterns and recent travel also change the clinical picture.

Write down symptom onset, travel dates, mosquito exposure, pregnancy status and medicines. Rest, drink fluids and prevent further bites with repellent, covered skin and screened spaces. Do not rely on a home guess to guide treatment or travel decisions. Arrange a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) for advice about testing, symptom relief and precautions, particularly if pregnancy is possible or confirmed.

Seek prompt advice for fever, rash, red eyes or new joint and muscle symptoms after travel or mosquito exposure. Get urgent help for breathing difficulty, confusion, fainting, severe dehydration, repeated vomiting or unusual bleeding. Contact a clinician promptly if you are pregnant, may be pregnant or have had a partner recently exposed in an area where Zika occurs. The same symptoms can have causes other than either infection.

Ask whether chikungunya, Zika or another illness fits your exposure history, whether testing is useful, what pregnancy precautions apply and how long to continue bite prevention. Mention your partner’s travel or illness when relevant.
