PerformInk is Chicago's entertainment industry trade publication.
Update – 3/14/20 3:30pm
PerformInk will no longer track show closings due to the Coronavirus, as most shows have decided to close, and re-opening dates and postponements are all fluid at this point. A handful of small theaters have decided to end runs as planned or stay open. If you are a ticket holder, you should contact the theater you are scheduled to attend for up-to-date info.
The City of Chicago has banned events over 1000 people temporarily, and the State of Illinois is asking that events with over 250 people be canceled.
