This is a second section of a spreadsheet obtained by The Documenting Covid-19 Project at Columbia University's Brown Institute for Media Innovation, in partnership with The Midwest Center for Investigative Reporting, through a public records request they made to a county agency. NBC5 Investigates and Telemundo Investiga Chicago have confirmed with IDPH officials that this is a confidential list kept by the state. This section of the spreadsheet is entitled "Outbreaks in ORS." ORS stands for the Outbreak Reporting System.
These outbreaks are all in downstate counties in Illinois. Scroll all the way to the right, to see extended descriptions of many of these cases. NBC5 and Telemundo have redacted all descriptions which might specifically identify individuals involved in each outbreak.
