Illinois cases now exceed one million

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

LANSING, Ill. (January 7, 2021) – This post includes data for the village of Lansing and data visuals for the state of Illinois.

“In a pandemic that has contained far too many tragic milestones, today’s marking of one million cases of COVID-19 diagnosed in Illinois deserves particular recognition,” said Governor JB Pritzker. “As this disease continues to wreak havoc on our nation—with the United States setting another record for the most COVID-19 deaths in a day just yesterday—it is critical that we take extra caution today and in the months ahead to reduce the spread, bring down hospitalization rates, and save lives. Now that vaccine distribution has begun, we can see the light at the end of this difficult time—let’s do everything we can to ensure all of our neighbors are able to be there as we cross that finish line, healthy as well. With that goal in mind, I encourage all Illinoisans to choose to receive the protections of the COVID-19 vaccine when it’s your turn in line.”


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: 2,610 (Previous reported total: 2,610)
  • Cumulative total of COVID-19 deaths: 13 (Previous day’s total: 13)
  • Current positivity rate: 12.08% (Previous reported rate: 12.04%)
  • Seven-day average positivity rate: 11.97%


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 preliminary seven-day statewide positivity for cases as a percent of total test from December 31, 2020 – January 6, 2021, is 8.5%. The preliminary seven-day statewide test positivity from December 31, 2020 – January 6, 2021, is 9.8%.


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.

The preliminary seven-day statewide positivity for cases as a percent of total test from December 20, 2020 – January 5, 2021, is 8.4%. The preliminary seven-day statewide test positivity from December 30, 2020 – January 5, 2021, is 9.9%.
