Methodology

Case Rate Per 100,000

Each day, for each region and county, a 7-day average case rate is calculated by dividing the sum of COVID-19 positive tests reported to IDPH over the most recent 7 days by the population, and multiplying by 100,000,  rounded to one decimal place. 

Calculation: 100,000*[Sum of positive tests for most recent 7 days] /population

Weekly Reported Deaths

Each week, for each region and county, the weekly count of deaths is calculated by counting the number of deaths that occurred because of COVID-19 and that were reported to IDPH during the previous week.

Calculation: Count of deaths due to COVID in a week.
