The number of measles cases in the United States has surpassed 2019's wave of infections, according to Centers for Disease Control and Prevention data.

There have been more measles cases in the US this year than any other since the disease was declared eliminated a quarter-century ago.

The U.S. has now recorded more confirmed measles cases this year than in any year in well over a quarter-century.

With nearly six months left in the year, the total number of cases so far in 2025 has surpassed every year since 1992

Measles cases in the United States are the highest they’ve been since the country eliminated the disease in 2000. The U.S. has reported 1,277 cases since the start of the year, according to NBC News’ tally of state health department data.

While weekly reported cases have slowed over the past few months, the CDC’s figure surpasses the high of 1,274 cases in 2019 and marks a grim milestone for the U.S. as immunization coverage wanes across the country and the federal government’s vaccine policy shifts under Health Secretary Robert F. Kennedy Jr.

Los Angeles, Orange, Riverside and San Bernardino counties have reported eight cases so far this year compared to 10 total in 2024.

The U.S. is having its worst year for measles spread in more than three decades, with a total of 1,288 cases nationally and another six months to go in 2025.
