CHICAGO (AP) -- Health authorities in Illinois are warning there will likely be more local cases of measles as they await laboratory tests expected to confirm that a total of five infants attending the same daycare center have been infected.
Lab results have already confirmed two of those cases, and doctors have diagnosed the other three based on symptoms. They attend a KinderCare Learning Center in the Chicago suburb of Palatine.
Children under 1 are too young to be vaccinated, putting them at particular risk.
KinderCare notified families that it will now require staff working with children under the age of 15 months to be vaccinated at all of its facilities nationwide.
Dr. Terry Mason of Cook County's health and hospital system says he expects more local cases to turn up.
