Expanding Measles Outbreak in Texas and New Mexico Prompts Centers for Disease Control and Prevention (CDC) to Issue Health Alert Network (HAN) Health Advisory

The Centers for Disease Control and Prevention (CDC) has issued a Health Alert Network (HAN) Health Advisory to notify clinicians, public health officials, and potential travelers about a measles outbreak in Texas and New Mexico and offer guidance for prevention and monitoring.

As of March 7, 2025, Texas and New Mexico have reported 208 confirmed cases of measles associated with this outbreak (198 in Texas and ten [10] in New Mexico). As a part of this outbreak, two (2) deaths have been reported: one (1) in Texas and one (1) in New Mexico. More cases are expected as this outbreak continues to expand rapidly. 

With spring and summer travel season approaching in the United States, CDC has emphasized the important role that clinicians and public health officials play in preventing the spread of measles. 

Measles-mumps-rubella (MMR) vaccination remains the most important tool for preventing measles. To prevent measles infection and spread from imported cases, all residents of the United States should be up-to-date on their MMR vaccinations—especially before traveling internationally—regardless of the destination.

CDC reports that the risk for widespread measles in the United States remains low due to robust immunization and surveillance programs and outbreak response capacity supported by federal, state, tribal, local, and territorial health partners.
