What should you know about Zika rash?

A viral rash may look like small pink or red spots or patches and may occur with fever, joint pain, red eyes, or headache. Many other conditions can look similar, including contact dermatitis, heat rash, drug rash, atopic dermatitis, psoriasis, ringworm, scabies, and intertrigo. A rash is a symptom, not a diagnosis.

Tell a clinician when the rash began, where it started, whether it itches or hurts, new medicines or products, recent travel, mosquito exposure, and contact with anyone who was unwell. Pregnancy or possible pregnancy makes timely medical advice particularly important because some mosquito-borne infections can affect fetal health.

Arrange medical advice if Zika is possible or the rash is accompanied by fever, joint symptoms, or red eyes. Avoid mosquito bites while unwell by using appropriate repellent, covering skin, and reducing mosquito exposure. Use separate towels, avoid sharing personal items, and ask about sexual-transmission precautions because Zika can spread through sexual contact.

Do not start antibiotics or stop a prescribed medicine based only on the rash. A clinician may recommend symptom relief and decide whether testing or another examination is appropriate. Keep a dated photo and list of medicines and exposures to support the assessment.

Seek urgent care for trouble breathing, swelling of the lips or face, faintness, confusion, severe headache, stiff neck, bleeding, purple spots, blistering, skin peeling, or a rapidly worsening illness. Prompt advice is also needed for a rash during pregnancy, in a newborn, or with marked dehydration or weakness.

Could this be an infection, medicine reaction, heat rash, or another skin condition? What symptoms should I monitor, do I need testing, and what precautions should I take around mosquitoes and sexual contact?
