Looks like a South Loop academy had a Covid-19 outbreak (via ABC7):

The Chicago fire academy is closed until further notice after an apparent COVID-19 outbreak impacting both students and instructors.
Officials said they are working to determine the source of the outbreak at the Robert J. Quinn Fire Academy, located at 558 W. De Koven Street in the South Loop. It's not clear how long the building will be shut down.
Officials have not said exactly how many people tested positive for COVID-19, but there are multiple cases. Those individuals are now in isolation and none require hospitalization. For now, the other trainees will participate in remote instruction.
