Chicago authorities warn of possible measles exposure at O’Hare

Chicago health authorities issued a measles exposure warning Tuesday after a contagious individual visited O'Hare International Airport and two other locations in the area. The Cook County Department of Public Health identified Terminal 5 at O'Hare as one exposure site and advised people who were there between 10:45 a.m. and an unspecified later time to monitor themselves for symptoms. Measles is highly contagious and can cause serious complications, making public alerts critical to prevent further spread. Individuals exposed should watch for fever, cough, and the characteristic rash and seek medical attention if symptoms appear, while confirming their vaccination status with a healthcare provider.
