Measles: what to do

Measles is a contagious viral illness that may begin with fever, tiredness, cough, runny nose, or sore eyes before a rash appears. Some people also develop swollen glands. Symptoms can overlap with other infections, so a clinician may need to assess the pattern, vaccination history, and any known exposure.

Because the infection can spread through the air, a person with suspected measles should avoid close contact with babies, pregnant people, and anyone with reduced immunity until a clinician gives advice. Do not arrive unannounced at a clinic, where other patients could be exposed.

Phone a GP or health service and explain the symptoms, when they started, and whether there was contact with someone who had measles. Ask how to be assessed safely; a GP consultation may be arranged with infection-control precautions.

Rest, drink fluids, and use only medicines suitable for the person’s age and health history. Keep a note of fever, new symptoms, and recent contacts. Do not share towels, cups, or utensils, and wash hands regularly. Ask about MMR vaccination if immunisation is incomplete or uncertain; vaccination decisions depend on age, records, pregnancy, and medical history.

Seek urgent medical help for breathing difficulty, severe drowsiness, confusion, a seizure, inability to drink, signs of dehydration, or a rapidly worsening illness. Tell the service that measles may be involved before travelling. For a less urgent concern, arrange prompt clinical advice, especially for a young child, pregnancy, or weakened immune system.

Could these symptoms fit measles or another infection? How should assessment be arranged without exposing others? Is MMR vaccination appropriate, and should close contacts receive advice? Which fever or pain medicines are suitable? How long should school, work, travel, or social contact be avoided?
