Health authorities are warning passengers of a possible measles exposure at Chicago O’Hare International Airport.
An adult diagnosed with measles spent time in Terminal 1, potentially coming into contact with hundreds of travelers. The individual, who had previously received one dose of the MMR vaccine, was at the airport on April 22 and 23 between 10 a.m. and 8 p.m. They developed a rash on April 25, and subsequent testing confirmed the infection. Since the diagnosis, the person has been isolating at home.
A second case was reported days later in an adult from the same Illinois county. While their vaccination status is unknown, the patient sought treatment at a local hospital on April 28, where staff promptly isolated them to prevent further spread.
Officials are urging anyone who may have been exposed to monitor for symptoms and contact their healthcare provider immediately. This incident marks the latest in a string of measles scares affecting major U.S. airports and nearby communities.
