While the state reported 5,368 new cases of COVID-19 on Sept. 4, that total included cases from several previous days, after the state cleared a backlog of cases caused by a slowdown in the public reporting of results.

The 4,015 new cases announced by IDPH is the most Illinois has reported from a single day of testing, and account for nearly 6% of the 67,086 new tests reported on Thursday. The statewide seven-day average positivity rate in Illinois is up to 4.9%, the highest it’s been since June 8, when that metric was at 5%, while Illinois was still in Phase 3 of its reopening plan.
