Health Officials Confirm 11th Measles Case in Cook County

Public health officials said 10 of the cases are related to the Palatine KinderCare Learning Center

Public health officials have confirmed an 11th measles case in Cook County.

The most recent case involves an infant who officials say they have been monitoring for several days, according to Cook County Department of Public Health spokeswoman Amy Poore.

Ten of the cases are related to the Palatine KinderCare Learning Center at the center of last week’s outbreak.

A spokesperson with the Illinois Department of Public Health and the Chicago Department of Public Health confirmed one case is a Chicago infant who is associated with KinderCare. Officials say eight other infants and one adult from the Palatine KinderCare have also been diagnosed, though the adult is not an employee with the facility.

Elgin Community College confirmed Tuesday that one case is an ECC student who is a Cook County resident associated with the KinderCare outbreak.

The one case not linked to the day care center was an adult who last month was the state's first confirmed diagnosis.

Doctors last week said there was no link between the first case and the KinderCare cases, and no link to any of them with the multi-state outbreak associated with Disneyland.

DuPage County issued a warning to residents Tuesday of the potential for exposure in the county. County officials said while there were no cases confirmed in the county as of Tuesday afternoon, it is likely those diagnosed in Cook County "visited locations throughout the northern Illinois region."

"The solution to ending measles is simple – get vaccinated," said Illinois Department of Public Health director Nirav Shah. "The vaccine is 97 percent effective upon receipt of two doses. But the vaccine alone doesn’t provide protection; it is the vaccination that will prevent disease. I urge everyone who is eligible to receive the vaccine to get vaccinated."
