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.

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

The United States has broken its record for the highest number of measles cases in the country since the disease was eliminated in 2000. It comes amid falling childhood vaccination rates and a rise in anti-vaccine sentiment fueled by lingering COVID-era distrust in public health authorities and a strengthening anti-vaccine movement.
