Measles

Recent Notices

Measles, also called rubeola or red measles, is a very contagious disease that is caused by a virus. Anyone who has not been immunized can get measles, but children are especially at risk.

Measles causes a red, blotchy rash that begins on the face and spreads down the body. Symptoms also include:

  • fever
  • cough
  • runny nose
  • red, watery eyes

Most people fully recover from measles within 2 to 3 weeks. But measles can sometimes cause dangerous problems, such as brain swelling (encephalitis) leading to seizures, hearing loss or even death. Since there is no cure, prevention is very important. The measles vaccine is a safe and effective way to prevent measles.
