COVID-19 Community Levels Map
IDPH experienced processing errors on October 20, 2022 that led to about 3,000 duplicate cases being included in the reported case data. These have now been corrected.
Daily deaths reported on weekends and at the beginning of the week may be low as IDPH and local health departments move away from reviewing and processing COVID-19 death records over the weekend. Those deaths will be captured in subsequent days. (March 4, 2022)
On January 22, 2021, IDPH began including in the total case count all probable deaths reported since the beginning of the pandemic. Due to this change, all probable deaths, 1,903, have been added to the one-day, January 22, 2021, total of new cases.
Beginning November 6, 2020 and going forward, IDPH will report confirmed cases and probable cases combined. Due to this change, all probable cases previously reported separately, 7,673, have been added to the one-day, November 6, 2020 total of new cases.
This is a rapidly evolving situation and information will be updated as needed here and on the CDC website at https://www.cdc.gov/coronavirus/2019-ncov/index.html.
