Health officials are sounding the alarm over a potential measles exposure at Chicago O’Hare International Airport.
An infected adult was mainly confined to the airport’s Terminal 1 area, potentially exposing hundreds of others to the world’s most infectious disease.
The person was at the airport – the world’s fourth busiest in terms of passenger numbers – on April 22 and April 23 between 10am and 8pm both days.
They had had one prior dose of the MMR vaccine but they went on to develop a rash on April 25 and tests confirmed they had contracted measles.
Since being being diagnosed, they have been been isolating home.
