Expanded Measles Vaccination Recommendations for Domestic Travel
As of April 3, 2025, the U.S. CDC had been notified of 607 confirmed cases of measles across 22 states and jurisdictions. Measles is an airborne, extremely infectious, potentially severe rash illness. Since January 1, 2025, 12% of reported measles cases in the United States have been hospitalized. At the time of sending this HAN, the U.S. CDC has confirmed two measles deaths in 2025.
The risk of measles infection remains low for most people in Maine given high rates of MMR immunization in the state. Likewise, across the United States, risk of infection remains low due to high immunization coverage in most communities and rapid case identification and response efforts underway. The measles, mumps, rubella (MMR) vaccination is safe, effective, and the best way to protect against measles and measles-associated complications.
