What should you know about monkey measles virus?

People sometimes use this phrase when they are worried about measles after contact with a monkey or another animal. Measles is a human viral illness; it is not the same as an infection acquired from monkeys. Typical illness can include fever, cough, runny nose, sore eyes, and a rash that begins on the face before spreading. Fever and swollen glands can have many causes, so symptoms alone cannot confirm measles.

If measles is possible, avoid close contact with babies, pregnant people, and anyone with reduced immunity until a clinician gives advice. Call ahead before attending a clinic so staff can reduce exposure to others.

Contact a GP or public-health service promptly if you have a new widespread rash with fever, or if you were exposed to confirmed measles. Rest, drink fluids, and use only medicines suitable for you; do not share towels, cups, or utensils. Ask about MMR vaccination if your immunisation history is incomplete. A clinician may arrange testing and explain isolation advice.

Seek urgent medical help for trouble breathing, confusion, severe weakness, dehydration, a seizure, or a rapidly worsening condition. Get prompt advice for a child, pregnancy, or a weakened immune system, even when symptoms seem mild. A high fever with a spreading rash should be assessed without waiting for the rash to settle.

Could this be measles or another rash illness? Do I need testing or isolation? Is my MMR vaccination record complete? What should household contacts do?
