In a follow-up to the recent Legionnaires’ disease clusters in Illinois, state and county health officials are investigating a cluster of three cases at McHenry Villa, an independent senior living community.
Public health officials confirmed the third case this week. McHenry Villa is notifying residents, the residents’ identified contact, and staff. All three cases had outside exposures, and two of the cases had potential exposures at Centegra Hospital-McHenry. Public health officials will continue to investigate any other potential sources.
