The Centers for Disease Control and Prevention says the U.S. is currently experiencing its worst measles outbreak in more than 30 years, according to the Associated Press. On Wednesday, the CDC said the 2025 case count has surpassed the 2019 count, when there were 1,274 cases for the year.

U.S. measles cases hit 1,277—the worst outbreak since the disease was declared eliminated in 2000, surpassing 2019's peak.

The Illinois Department of Public Health has reported 10 measles cases in the state so far this year. There were 67 cases last year.

While measles symptoms typically resolve in a few weeks, the virus can cause pneumonia, making it difficult for patients, especially children, to get oxygen into their lungs. It may also lead to brain swelling, which can cause lasting damage, including blindness, deafness and intellectual disabilities.

Health experts say the true case count may be higher. Measles was considered eliminated in the U.S. in 2000, but if cases continue to rise at the rate it has, that status could change. The United States just reported its highest number of measles cases in more than three decades.
