Measles remains a common disease in many parts of the world, including areas in Europe, Asia, the Pacific, and Africa. Worldwide, about 20 million people get measles each year; about 146,000 die. In the United States, most of the measles cases result from international travel. The disease is brought into the United States by unvaccinated people who get infected in other countries. They spread measles to others, which can cause outbreaks.
Anyone who is not protected against measles is at risk of getting infected when they travel internationally.
Some U.S. travelers have become sick with measles after traveling abroad. Before you leave on an international trip, check the CDC Travel Notices on measles.
