Already in 2025, the United States has reported more measles cases than in any full year since the early ‘90s, according to federal data. And that record-setting case count has been driven by a massive outbreak that began in Texas.

Measles cases in the United States have reached their highest number in more than 30 years, according to new federal data published Wednesday.

CDC data shows 2025 is now the worst year for measles cases in this country in more than three decades. More than 150 people have been hospitalized due to the growing outbreak and three have died, including two unvaccinated children in Texas.
