On Feb. 26, 2025, Texas health officials announced the death of a child in a measles outbreak – the first measles death in the United States since 2015. The outbreak was first identified in early February in Gaines County, Texas, where just 82% of kindergartners are vaccinated against measles, compared with 93% on average across the country. As of Feb. 27, there were at least 124 confirmed cases in Texas and nearby towns in New Mexico.
In an interview with The Conversation U.S. associate health editor Alla Katsnelson, neurologist and medical epidemiologist Daniel Pastula, MD, MHS, explains why measles is so dangerous and how people and communities can protect themselves from the virus.
