LANSING, Ill. (March 23, 2021) – This post includes data for the village of Lansing and data visuals for the states of Illinois and Indiana.

“Even as we’re getting more and more vaccine doses, we cannot let our guard down, especially with these virulent new strains circulating,” said IDPH Director Dr. Ngozi Ezike. “We’ve come so far and are so close to a more normal time, but we’re already seeing some concerning plateaus and even increases in hospitalizations and cases. We’re not out of the woods yet, so continue to wear your masks, avoid large crowds, and keep six feet of distance.”


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: 3,080 (Previous reported total: 3,079)
  • Cumulative total of COVID-19 deaths: 18 (Previous day’s total: 17)
  • Seven-day positivity rate: 4.63% (reported March 19)


The graphs below are created by HiGeorge and are “live,” so they are continually updated as new data are released from official sources.

The Illinois Department of Public Health (IDPH) today reported 1,832 new confirmed and probable cases of coronavirus disease (COVID-19) in Illinois, including 13 additional deaths.

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 March 16-22, 2021, is 2.5%. The preliminary seven-day statewide test positivity from March 16-22, 2021, is 2.9%.

Illinois vaccinations

A total of 5,796,305 vaccine doses have been delivered to providers in Illinois, including Chicago. In addition, approximately 414,900 doses total have been allocated to the federal government’s Pharmacy Partnership Program for long-term care facilities. This brings the total Illinois doses to 6,211,205. A total of 4,818,097 vaccines have been administered in Illinois as of last midnight, including 363,235 for long-term care facilities.

The seven-day rolling average of vaccines administered daily is 91,000 doses. Yesterday, 70,252 doses were reported administered in Illinois.

IDPH is working with the federal government on discrepancies in some of the vaccine administration data. The result of the discrepancy could be that the number of doses actually administered at this time may be underreported. IDPH will update the data as soon as the discrepancy is resolved.
