Measles remains a common disease in many parts of the world, including areas in Europe, Asia, the Pacific, and Africa. Worldwide, 19 cases of measles per 1 million persons are reported each year; about 89,780 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.
