What happens if measles is not treated?

Measles is a highly contagious viral illness. Fever, cough, runny nose, sore eyes, and a spreading rash can leave someone exhausted and unable to drink enough. Complications may include dehydration, middle-ear infection, pneumonia, or inflammation of the brain. Risk is higher for babies, pregnant people, adults with severe illness, and people with weakened immunity.

A person can spread measles before the rash is obvious and while ill. Avoiding shared waiting rooms protects others, especially infants and people who cannot be vaccinated. A rash with fever needs clinical advice because several illnesses can look similar.

Call a GP Consultation service before attending in person and say that measles is possible, so infection-control arrangements can be made. Rest, take fluids in small frequent amounts, and use fever relief only as advised for the person’s age and health. Do not share towels, utensils, or close indoor space, and follow local public-health instructions about isolation and contact advice.

Get emergency help for breathing difficulty, blue lips, severe drowsiness, confusion, a seizure, inability to drink, very little urine, or a severe headache with neck stiffness. Seek prompt advice for a child who is worsening, persistent fever, ear pain, or signs of dehydration. Tell the service about possible measles before arrival.

Ask whether the illness needs testing, how to maintain fluids, how long to stay away from others, and which contacts need advice. For future prevention, discuss whether MMR Vaccination is suitable and check the person’s vaccination record.
