A rural Illinois bar opening event in February was linked to a Covid-19 outbreak of at least 46 cases, a school closure and the hospitalization of a long-term care facility resident, according to a United States Centers for Disease Control and Prevention report.

The Illinois Department of Public Health identified 29 individuals who tested positive for Covid-19 or had Covid-19-like symptoms within 14 days after the indoor bar opening event. All 29 cases were confirmed by Covid-19 antigen or nucleic acid amplification tests except for one probable symptomatic case who did not receive testing.
