Measles Outbreak under control

The Illinois Department of Public Health has announced that the largest measles outbreak to affect the state of Illinois since 1990 is officially contained. No new cases have been reported for more than 42 days, which is two full incubation periods. A total of 67 measles cases were reported during the outbreak, which started March 7, with the vast majority linked to a Chicago shelter for migrants. Cases eventually extended beyond Chicago to suburban Cook County, DuPage, Lake and Will counties, but were rapidly contained in all the other locations.
