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

The U.S. has hit an unwelcome milestone in measles cases this year. The CDC is reporting 1,288 cases across the country. The disease was declared eliminated 25 years ago.

The US Centers for Disease Control and Prevention on Wednesday tallied the highest number of US measles cases since the disease was declared eliminated a quarter-century ago, just as a key Senate committee split the vote to advance President Donald Trump’s nominee to lead the public health agency.

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.
