What should you know about measles?

Early illness may include fever, cough, runny nose, sore or red eyes, and small spots inside the mouth. A rash often begins on the face or hairline and moves down the body. Swollen glands can occur. The virus spreads through air and respiratory droplets, so people can infect others before the rash is obvious.

Measles can be more serious in babies, pregnant people, adults with reduced immunity, and people with poor nutrition. Complications may affect breathing, hearing, or the nervous system. A suspected case should be assessed with infection-control arrangements.

Call a GP or clinic before attending in person and describe the fever, rash, and any exposure. This allows the service to reduce contact with other patients. Rest, drink fluids, and use fever relief only as directed for your age and health needs. Do not share towels, cups, or eating utensils.

Check vaccination records for yourself and close contacts. MMR vaccination is the main preventive measure and a clinician can advise on catch-up doses or post-exposure options. Keep away from school, work, and vulnerable people until a healthcare professional says it is appropriate to return.

Get emergency help for difficulty breathing, blue lips, severe dehydration, unusual drowsiness, confusion, a seizure, or a severe headache with a stiff neck. Seek prompt clinical advice for a high or persistent fever, worsening cough, eye pain, or a child who is drinking very little. Mention pregnancy or reduced immunity when you call.

Ask whether the illness needs testing, how long isolation should last, which fever medicines are suitable, and whether household contacts need urgent vaccination advice. Confirm warning signs, fluid goals, and the safest way to arrange follow-up without exposing other patients.
