What is measles?

Measles is a highly contagious respiratory disease that is spread through the air when an infected person coughs or sneezes. Measles symptoms start with a fever, runny nose, cough, and red eyes, and are followed by a rash that spreads all over the body. Learn more about measles.

What can you do?

Vaccination with two doses of MMR vaccine is a safe and effective way to prevent measles.

Know if you and your children are protected. Two doses of MMR vaccine provide long-lasting protection against measles. Those who have previously been infected with measles are also protected from being infected with measles again.

Get vaccinated if you are not already vaccinated or are unsure of your vaccination status. Talk with your healthcare provider about getting vaccinated or having a blood test to check for immunity to measles.

Vaccinate your children. The MMR vaccine is included in the routine childhood immunization schedule. Children should receive the first dose at 12-15 months and the second dose at 4-6 years. Older children can be vaccinated, too, if they haven't already.

Call your healthcare provider if you think you or your child might have measles. Call before going to the medical office so the office can take steps to prevent others from being exposed to measles.

If you have more questions about measles, please contact your healthcare provider.

Measles and travel

Measles is still common in many parts of the world in Europe, Asia, the Pacific, South America, and Africa. People planning international travel should ensure they have already received the recommended two doses of MMR vaccine. Talk to your doctor about travel immunizations at least 4-6 weeks before traveling.
