Per CDC data, there have been over 1,670 confirmed measles cases reported in the U.S. this year. For comparison, there were 2,286 confirmed cases reported in all of 2025, which is more than any year since 1991 and could put the U.S. measles elimination status at risk.
About 92% of people who have contracted measles this year have been unvaccinated or had an unknown status. Experts say it is likely that cases are significantly undercounted, as many go unreported.
The AAP recommends ensuring patients are covered with a two-dose measles, mumps, and rubella (MMR) vaccination series. Read the full update in AAP News:
