Measles

Also called Rubeola

Measles is a highly infectious illness caused by a virus. It usually starts with cold-like symptoms and red, sore eyes, followed a few days later by a blotchy rash that starts on the face and behind the ears and spreads. It can lead to serious problems such as pneumonia and encephalitis, especially in babies, pregnant women and people with weak immune systems.

What it is

There is no specific treatment. Rest, fluids and fever relief help, and some people need hospital care.

Two doses of the MMR vaccine give very good protection. People with measles should stay away from others for at least 4 days after the rash appears.

Common signs

  • High temperature
  • Runny or blocked nose, sneezing and cough
  • Red, sore, watery eyes
  • Small white spots inside the cheeks
  • A blotchy rash that spreads from the head down

How it is usually diagnosed

  • Examination and symptoms
  • A saliva or blood test to confirm

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Notes on complications or hospital stays

Questions to ask your doctor

  • Is everyone at home vaccinated?
  • When is it safe to go back to school or work?
  • What complications should I watch for?

When to get help right away

Call 112 or go to the nearest emergency department if you have:
