Measles transmission in the United States and Canada continues to increase, including recent cases of measles reported in other New England states. Measles cases have been increasing rapidly in the US since early 2025 with large, extended outbreaks as fewer people have gotten the measles, mumps, and rubella (MMR) vaccine. Before that, most measles cases were tied to international travel. Measles is still common in many countries and easily spreads through communities of unvaccinated people. Unvaccinated travelers to and from those areas of the US and other countries can spread it to others.
Measles can be severe. In 2025, 1 out of every 10 people diagnosed with measles in the US was hospitalized and 3 people died from measles. Complications include diarrhea, middle ear infections, pneumonia, hepatitis, and encephalitis (swelling of the brain). Learn more about measles
