Information for Patients


Also called: Rubeola

Measles is an infectious disease caused by a virus. It spreads easily from person to person. It causes a blotchy red rash. The rash often starts on the head and moves down the body. Other symptoms include

  • Fever
  • Cough
  • Runny nose
  • Conjunctivitis (pink eye)
  • Feeling achy and run down
  • Tiny white spots inside the mouth

Sometimes measles can lead to serious problems. There is no treatment for measles, but the measles-mumps-rubella (MMR) vaccine can prevent it.

"German measles", also known as rubella, is a completely different illness.
