All data points are provisional and subject to change upon completion of the investigation for each locally reported case to the Skokie Health Department. Daily case counts may change over time due to corrections in case jurisdiction, testing status, or identification of duplicate cases. The Skokie Health Department reports investigation data to the Illinois Department of Public Health (IDPH) through the Illinois-National Electronic Disease Surveillance System (I-NEDSS) on a continual basis. Based on when IDPH accesses the information, the reports issued at the State level may be different from what is being reported at the local level. The data for all graphs is updated daily, Monday through Friday, except for the graphs showing Skokie's positivity rate and the progression of vaccinations in the community which are updated weekly on Tuesdays.
