(CNN) Parents at a Chicago-area day care center are keeping a close watch over their children for any signs of fever or rashes. They learned Wednesday that two infants who attend a KinderCare Learning Center in Palatine, Illinois, have tested positive for measles.
Three more cases have been diagnosed, based on clinical and other criteria, but results are pending, according to a statement from the Cook County Department of Public Health and state officials.
Officials say it is not clear whether these cases are linked to a previously confirmed case in suburban Cook County or to the outbreak associated with Disneyland in California.
