Health officials have issued a warning about possible measles exposure at Chicago’s O’Hare Airport.
An infected individual spent time in Terminal 1 on April 22-23 between 10am and 8pm, potentially exposing hundreds to the highly contagious disease.
The patient, who had received one dose of the MMR vaccine, developed a rash on April 25 and later tested positive for measles. They are currently isolating at home while health authorities investigate the case.
A second measles case emerged days later in the same Illinois county.
