Colorado has not recorded a case of measles this year, according to the state health department, but officials believe it may only be a matter of time.
A total of 222 measles cases were reported by 12 states, as of March 6, 2025, according to the CDC: Alaska, California, Florida, Georgia, Kentucky, New Jersey, New Mexico, New York, Pennsylvania, Rhode Island, Texas, and Washington.
Two more cases popped up in nearby Oklahoma on Tuesday. In all of 2024, the U.S. recorded 285 cases.
Measles is a highly contagious, airborne, respiratory infection, perhaps best known for its rash and fever, which can cause serious health problems, especially for children under the age of 5.
