COVID-19 Data

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 is updated as available from IDPH. 

Illinois Department of Public Health (IDPH) calculates Community Risk Levels for COVID-19 based on the county transmission rate (number of officially diagnosed COVID-19 cases for the last 7 days) and COVID hospitalization information.  To see this information, please visit IDPH COVID-19 Community Risk Levels.

Positivity Rate - On April 12, IDPH announced it is using new federal guidelines for tracking COVID-19 at the community level.  The new CDC guidelines emphasize the case rate and hospitalizations in order to better track the impact of COVID-19 in communities.  In addition, as a result of HHS announcing that testing providers are no longer required to report some negative test results, IDPH and Skokie will no longer know how many tests are being done and will therefore no longer report test and case positivity.

Avg. Cases/Day - total number of tests administered as reported to the IDPH Electronic Lab Reporting System for Skokie Residents for the week (Monday – Sunday) divided by 7 days

Transmission Rate - The number of new confirmed positive COVID-19 cases per 100,000 population for Skokie residents in a 7 day period.  Number of confirmed cases for 7 days (Monday – Sunday) divided by Skokie’s 2020 Census Population (67,824) x 100,000 population

Vaccination Data
Information on the overall percentage of Skokie residents that have received at least one dose of COVID-19 vaccine, as well as the percentages of residents ages 65 and older and residents ages 18 and older that have received at least one dose of COVID-19 vaccine.

5/17/2022 - Skokie Resident COVID-19 vaccination percentages for specific indicators may show a subtle decrease in vaccination percentages effective the week of May 16 due to Illinois Department of Public Health (IDPH) ongoing data review and quality assurance efforts.  IDPH reported that data for previously reported COVID-19 vaccine doses administered are being continuously updated. Therefore, previously reported numbers may change to reflect the updated data. IDPH will continue to report the number of COVID-19 vaccine doses administered daily, but is should be noted that IDPH is updating COVID-19 vaccination data twice a month.
