LANSING, Ill. (December 26, 2020) – 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: 2,446 (Previous reported total: 2,446)*
  • Cumulative total of COVID-19 deaths: 13 (Previous day’s total: 13)
  • Current positivity rate: 11.90% (Previous reported rate: 11.90%)
  • Seven-day average positivity rate: 11.86%
  • *

*It is not clear when these numbers were last updated.


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 3,293 new confirmed and probable cases of coronavirus disease (COVID-19) in Illinois, including 70 additional deaths.


Following Centers for Disease Control and Prevention guidance, IDPH reports confirmed cases and probable cases combined. A confirmed case is laboratory confirmed via molecular test. A probable case meets clinical criteria AND is epidemiologically linked, or has a positive antigen test. If a probable case is later confirmed, the case will be deduplicated and will be counted only once. Probable deaths and confirmed deaths will continue to 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.
