How long does measles last?

Measles often begins with fever and a generally unwell feeling, followed by cold-like symptoms and irritated eyes. A rash then appears and spreads across the body before fading. Cough and tiredness may remain after the skin looks better. Swollen glands can occur with viral illnesses, but the combination of symptoms needs clinical assessment because several infections can look alike. The person can spread measles around the early symptom period and while the rash is active, so timing matters for contact advice.

Call a GP consultation service before attending in person if measles is possible, so the practice can reduce exposure to other patients. Rest, drink fluids, and use only medicines suitable for the person’s age and health. Keep the unwell person away from school, childcare, work, and vulnerable contacts until a clinician advises that returning is appropriate. Check vaccination history with a healthcare professional; MMR vaccination helps prevent measles and other infections.

Seek urgent medical help for breathing difficulty, severe drowsiness, confusion, a seizure, dehydration, or a fever that is worsening or not settling. Babies, pregnant people, and anyone with a weakened immune system should receive prompt advice after possible exposure or when symptoms begin. Do not arrive unannounced at a clinic if measles is suspected, because it spreads easily.

Ask how long to stay away from shared settings, whether close contacts need urgent advice, and whether vaccination records change the plan. Tell the clinician when fever and rash began, who may have been exposed, and whether breathing or drinking has become difficult.
