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

The epicenter of the crisis is Texas, particularly Gaines County, where 414 of the state’s 753 cases have been reported

Measles was considered eradicated in the United States in 2000. For the first time in 25 years, cases have reached a new high.

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.

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.

Three deaths reported nationally as Ohio's outbreak ends with 35 cases, while Texas accounts for 753 infections in the largest national surge since measles was declared eliminated in 2000.
