Symptoms of measles generally begin within 7-14 days after exposure. It starts with a fever, runny nose, cough, red eyes and sore throat and is followed by a rash that spreads all over the body. It can also cause severe complications like pneumonia and encephalitis.

If people experience measles-like symptoms, they should see a health care provider. Those most at risk of being infected with the measles are people who have had no doses or only one dose of MMR (measles, mumps and rubella) vaccine or who have not had the measles.

Measles vaccination is highly effective. Studies show more than 97 percent of people who receive two doses of vaccine are protected.
