information gathered from the Illinois Department of Public Health and the SSMMA COVID dashboard

LANSING, Ill. (January 22, 2021) – This post includes data for the village of Lansing and data visuals for the state of Illinois.


The South Suburban Mayors and Managers Association has created a COVID dashboard aggregating data from villages throughout the south suburbs. Highlights from Lansing are listed below:

  • Cumulative total of COVID-19 cases: 2,798 (Previous reported total: 2,784)
  • Cumulative total of COVID-19 deaths: 14 (Previous day’s total: 14)
  • Current positivity rate: 11.71% (Previous reported rate: 11.77%)
  • Seven-day average positivity rate: 11.87%


The graphs below are created by HiGeorge and are “live,” so they are continually updated as new data is released from official sources. For that reason, the numbers within a graph might not match the number in the text of this post, depending on when the post is being viewed.

The Illinois Department of Public Health (IDPH) today reported 7,042 new confirmed and probable cases of coronavirus disease (COVID-19) in Illinois, including 95 additional deaths.


Beginning today, IDPH has adjusted reporting probable cases, which caused an artificial one-day increase in cases of 1,903. Previously, only confirmed deaths were included in the total case count. However, the total case count includes both confirmed and probable cases. Therefore, probable deaths are now being included in the total case count. Confirmed deaths and probable deaths will still be reported separately.



Case positivity and test positivity rate are both relevant and offer insight into the bigger COVID-19 picture. Case positivity helps us understand whether changes in the number of confirmed cases is due to more testing or due to more infections. Test positivity accounts for repeated testing and helps us understand how the virus is spreading in the population over time.

The preliminary seven-day statewide positivity for cases as a percent of total test from January 15–21, 2021, is 5.0%. The preliminary seven-day statewide test positivity from January 15–21, 2021, is 6.2%.


As of last night, 781,350 doses of vaccine were delivered to providers in Illinois, including Chicago. In addition, approximately 304,600 doses have been allocated to the federal government’s Pharmacy Partnership Program for long-term care facilities. This brings the total Illinois doses to 1,085,950. IDPH is currently reporting a total of 508,732 vaccines administered, including 69,976 for long-term care facilities. Yesterday, a total of 13,169 doses were administered. The 7-day rolling average of vaccines administered daily is 22,134 doses.
