Since the actual CDC is being blocked from posting updates on outbreaks, I will do it myself.
As of June 19, 2025, a total of 1,214 confirmed* measles cases were reported by 36 jurisdictions: Alaska, Arkansas, Arizona, California, Colorado, District of Columbia, Florida, Georgia, Hawaii, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Missouri, Montana, Nebraska, New Jersey, New Mexico, New York City, New York State, North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Dakota, Tennessee, Texas, Vermont, Virginia, and Washington.
There have been 23 outbreaks** reported in 2025, and 89% of confirmed cases (1,081 of 1,214) are outbreak-associated. For comparison, 16 outbreaks were reported during 2024 and 69% of cases (198 of 285) were outbreak-associated.
*CDC is aware of probable measles cases being reported by jurisdictions. However, the data on this page only includes confirmed cases.
**CDC reports the cumulative number of measles outbreaks (defined as 3 or more related cases) that have occurred this year in the U.S.; states have the most up-to-date information about cases and outbreaks in their jurisdictions.
Please check your local health department to check on the risk in your area and follow their recommendations to avoid infection. Most cases are in the unvaccinated population, so if you are able to get the MMR vaccine and haven’t already, please reach out to your doctor to get that done
