SPRINGFIELD — The Illinois Department of Public Health on Tuesday confirmed the state’s first measles case of 2025, involving an adult in far southern Illinois. The patient received care at a local clinic, and health officials are working to identify any potential exposures. All exposed health care workers were masked and are considered immune. The case is not considered an outbreak, and the risk to the general public remains low. IDPH is urging residents to ensure they are up to date on measles, mumps, and rubella (MMR) vaccinations, especially those traveling to areas with known outbreaks.
