CHICAGO — Five infants who attend a suburban Chicago day-care center have been diagnosed with measles and about 10 more children, including some also too young for vaccinations, could have been exposed to the disease, health officials said Thursday.
The Illinois and Cook County health departments said in a news release that lab tests confirmed measles in two infants who go to the KinderCare Learning Center on East Palatine Road in Palatine. Tests are pending for three others, but they have been diagnosed based on symptoms.
Officials had not identified the source of the infections at the center as of Thursday, but Dr. Terry Mason, chief operating officer for the county’s health and hospitals system, told a news conference there is no known link between the infants’ measles and a recent outbreak at Disneyland that sickened dozens of people.
Mason said children who have not been vaccinated — whether infected or exposed — should not return to the Palatine center until Feb. 24 or until they provide proof of vaccination or immunity to measles, which is spread through the air when an infected person coughs or sneezes.
