Texas health officials declared the state’s measles outbreak over after more than 42 days without a new infection, the benchmark public-health threshold for ending an outbreak. The last related case was reported on July 1, and the formal announcement came from the Texas Department of State Health Services on 18 August. The virus sickened 762 people between late January and early July, hospitalised about 100 and killed two school-aged children—the first U.S. measles deaths since 2015. More than two-thirds of infections were in children, and the outbreak began in an under-vaccinated Mennonite community in West Texas before seeding cases elsewhere in the state and in neighbouring New Mexico. It was the largest U.S. measles outbreak in more than three decades and accounted for more than half of the nation’s cases so far this year. Commissioner Jennifer Shuford credited aggressive testing, vaccination drives, disease monitoring and public-awareness campaigns for containing “one of the most contagious viruses” and thanked health-care workers who, in many instances, were treating measles for the first time. She cautioned that Texas could still see additional cases, given ongoing outbreaks in North America and national vaccination gaps. The United States has logged more than 1,350 infections in 2025, threatening the elimination status it has held since 2000.
