This isn’t just a bad year for measles. It looks to be the start of a bad era. Confirmed measles cases just hit a 35-year high, and it’s only July. Together with last year, the number of cases has exceeded the combined total over the previous 25 years. The vast majority of cases stem from domestic outbreaks fueled by low rates of vaccination—and rates are declining.
For the first time in a quarter century, the U.S. no longer meets a main criterion for having eliminated measles as a public health threat. That status hinges on sporadic outbreaks fizzling out within a year. Utah’s outbreak has lasted for longer, since June 2025.
Nearly 400 people have been hospitalized with measles in the U.S. this year and last, three people have died, and at least three suffered brain swelling with lingering symptoms.
This month, the Centers for Disease Control and Prevention is set to finalize a comprehensive study of the nation’s measles situation, examining data from January 2025 through June 2026.
“I don’t think we could say with a straight face that there hasn’t been transmission over the past 12 months,” said a CDC scientist with knowledge of the agency’s measles report. (KFF Health News agreed not to name the researcher, who is concerned about retaliation.) The researcher said a national committee of measles specialists will review the CDC’s internal report, which then goes to the Pan American Health Organization, a group that evaluates the measles elimination status of countries throughout North, South, and Central America and the Caribbean.
