Though some schools offer case trackers of their own, IDPH releases data each week showing COVID outbreaks from the previous 30 days at schools across the state.

According to the health department, outbreak information is reported once an investigation is considered complete. An outbreak is defined as "those that have been identified by the local health department to have two or more COVID-19 cases who may have a shared exposure on school grounds and are from different households."

Here is a full list of school outbreaks reported by state officials.
