Where do cases of measles that are brought into the United States come from?

Measles can be brought into the United States from any country where the disease remains endemic or where outbreaks are occurring including Europe, Africa, Asia, and the Pacific Islands. In recent years, many measles cases have been brought into the United States from common U.S. travel destinations, such as England, France, Germany, India, and, during 2014, from the Philippines and Vietnam.
