In a statement, the city said additional "exposures may have occurred" Thursday at O’Hare International Airport, the University of Illinois Chicago (UIC) campus and the Chicago Loop. Residents may have also been exposed in Millennium Park, retail establishments on State Street between Monroe and Randolph Streets, and on South Canal Street, according to the city.

“Measles is a serious yet preventable disease through a safe, effective and universally available vaccine,” said CDPH Commissioner Julie Morita, M.D. “Chicagoans should make sure their children and family members are up to date on vaccines now. Vaccination is the best way to protect against measles.”

The city said its health officials are monitoring high-risk locations to contain exposure.
