Measles Cases Continue to Rise

As of May 15, 2025, a total of 1,024 confirmed measles cases in the U.S. were reported by 31 jurisdictions (Alaska, Arkansas, California, Colorado, Florida, Georgia, Hawaii, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Missouri, Montana, New Jersey, New Mexico, New York City, New York State, North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, Tennessee, Texas, Vermont, Virginia, and Washington). Over one-third of all the measles cases (38%) are in school-aged children or teens, and 30% occurred in children younger than 5 years old. Out of the 1024 total cases, 128 (13%) persons were hospitalized. The highest hospitalization rate (23%) occurred in children under 5 years of age. This information underscores the fact that measles can lead to dangerous complications, especially in children less than 5 years old. Ninety-six percent of individuals who acquired this illness were unvaccinated or had unknown vaccination status.

Approximately 92% of the confirmed measles cases were associated with outbreaks in Texas, New Mexico, Kansas, Ohio, Indiana, Michigan, Illinois, and North Dakota. The remaining 8% of cases were associated with international travel to countries where measles spreads regularly. In March, three cases of measles were reported in Maryland: 1 Howard County resident who recently travelled internationally and 2 Prince Georges County residents who also recently travelled abroad. None of the cases in Maryland were associated with the ongoing outbreaks.
