Tracking COVID-19: Confirmed cases in Harvey down 80% over past month
The decline follows a statewide and national plunge in cases of the highly contagious Omicron variant.

On Friday, the Illinois Department of Public Health reported 29,939 confirmed COVID-19 cases across the state since February 4. That’s down 50% from January 28 when the state reported 60, 939 COVID-19 cases. The current statewide test positivity rate is 5.8%.*
As cases decline dramatically statewide, Governor JB Pritzker announced that if the current decline in COVID-19 cases continues, the state’s indoor mask mandates would be lifted February 28, except in schools.
If the outlook improves, Cook County Department of Public Health officials plan to lift current mitigations by the same date. The County currently requires proof of vaccination in bars, restaurants, and gyms.
The Omicron surge in Chicago’s south suburbs began receding early last month, consistent with a national and statewide decline in COVID-19 cases. In Harvey, there has been a 80% decline in COVID-19 cases this past month, according to data with the CCDPH.

*The Illinois State Department of Public Health calculates test positivity by dividing the total number of positive COVID-19 tests for 7 days by the total number of COVID-19 tests performed during the same 7-day period.
**The Cook County Department of Public Health updates weekly case counts every Wednesday. Data reflect cases reported the previous Sunday through Saturday.
***The CCDPH calculates percent change by comparing case counts from the past 14 days to the 14 days preceding that.
****The Centers for Disease Control and Prevention considers fully vaccinated to mean having received all primary doses of a COVID-19 vaccine. That’s 2 shots for Pfizer and Moderna and 1 shot for Johnson & Johnson.
