Measles is still common in many parts of the world, including countries in Europe, Asia, the Pacific, and Africa. The United States has also seen a high number of measles cases. The majority of people who get measles are unvaccinated.

Measles is highly contagious, causing high fever and rash all over the body. Infection can be serious and more severe in young infants, pregnant women who are not immune to measles, and persons with a weak immune system. 

Complications may include:

• Ear infection
• Diarrhea
• Pneumonia
• Brain inflammation
• Death

The measles vaccine is very effective and safe, with the benefits far outweighing any risks. Children should receive their first dose of MMR vaccine routinely at 12 months of age and their second dose between ages 4 and 6 years. 

Adults without documentation of either prior measles vaccination or an immunity to measles should contact their healthcare provider to ask about a blood test to see if they are immune or for vaccination information. There is no harm in receiving additional doses of MMR vaccine. 

You should contact your healthcare provider to check your vaccination status before international travel.
