Facts about measles

Measles spreads through the air after a person with measles coughs or sneezes. People are contagious with measles for four days before a rash appears and up to four days afterward. The virus particles also can linger in the air for up to two hours after someone who is infectious has left the area.

Measles typically starts with a fever, cough, runny nose and red eyes. A rash usually follows, beginning on the face and spreading to the rest of the body. Symptoms begin seven to 21 days after exposure to a person with measles. Common complications of measles include ear infection, lung infection and diarrhea. Swelling of the brain is a rare but much more serious complication.

Measles can be dangerous, especially among children younger than 5, adults older than 20, pregnant people, and people with weakened immune systems. In developed countries in recent years, one to three of every 1,000 measles cases has been fatal. The measles vaccine is highly effective at providing protection, as two doses of the MMR vaccine is 97% effective at preventing the virus. The risk of severe disease from measles for people who are up to date on their vaccines is very low.

What to do if you suspect measles in your household

Public health officials urge people experiencing symptoms of measles not to arrive unannounced at a medical office if they:

Have a measles-like rash, or
Have been exposed to measles within the previous 21 days, AND have any other symptom of measles (such as fever, cough or red eyes). Whenever possible, individuals planning to seek medical care should first call your health care provider or urgent care center by telephone to create an entry plan to avoid exposing others in waiting rooms.
