Cook County health department officials confirmed a 15th case of measles in Illinois on Wednesday.
Officials say the latest case is an adult, but does not appear to be related to the KinderCare Learning Center at the center of a northwest suburban outbreak.
All 15 cases reported statewide are in Cook County and 13 of them are related to the outbreak at the KinderCare Learning Center, including one adult and 12 infants.
Officials say potential exposure from the newest confirmed case may have occurred at the following places:
• LaRosita Laundromat at 1212 E. Dundee Rd. in Palatine on Feb. 16
• Vista Clinic at 1585 North Rand Road in Palatine on Feb. 19
Illinois health officials are still trying to figure out how the people became infected with the measles virus. No ties have been found to the December outbreak at Disneyland in California, health officials said.
