Each year, on average, 60 people in the United States are reported to have measles. But the number of cases reported so far in 2013 is higher than usual—from January 1 to August 24, 2013, 159 people have been reported to have the disease. This is the second largest number of cases in the U.S. since measles was eliminated in 2000. About 26% of these people got measles in other countries. They brought the disease to the United States and spread it to others. This caused 8 measles outbreaks in various U.S. communities, including the largest U.S. measles outbreak since 1996 (58 cases). See Measles—United States, January 1-August 24, 2013 for more information.
Measles was declared eliminated from the United States in 2000. So, the disease no longer spreads year round in this country. But it is still common throughout the world, including some countries in Europe, Asia, the Pacific, and Africa. Anyone who is not protected against measles is at risk of getting infected when they travel internationally. They can bring measles to the United States and infect others. Unvaccinated people put themselves and others at risk for measles and its serious complications.
Children, teenagers, and adults should be up to date on their measles vaccination, including before they leave for international travel. For more information, visit For Travelers.
