CHICAGO (AP) — An indoor event at a rural Illinois bar led to 46 cases of COVID-19, one resident of a long-term care facility being hospitalized and a school closure.

That’s according to a Centers for Disease Control and Prevention report released Monday. The Illinois Department of Public health was notified on Feb. 17 of an outbreak.

The positive cases include 26 bar patrons, three staff members and 17 secondary cases. The report doesn’t name the establishment or local health department that investigated but a citation in the report shows several authors work for the Douglas County Health Department. A health department spokeswoman hasn’t commented on the report.
