A measles case has been confirmed in a DuPage County resident, marking the county's first case since 2009, health officials said. The source of infection is currently unknown, as the case does not appear to be linked to the Chicago outbreak.
According to health officials, the individual diagnosed with measles has received outpatient medical care and is recovering.
There have not been any exposure locations identified in DuPage County, though several exposure locations in Chicago from April 2 to April 10 have been identified, and can be found here.
Health officials advise that unvaccinated individuals, or those who are unsure about their vaccination status, and were at any of the exposure locations in Chicago may have been exposed to measles.
