SPRINGFIELD — COVID-19-related deaths surpassed 8,000 over the weekend as the virus positivity rate hovered around 4%.

As of Monday, the rolling seven-day average positivity rate throughout the state was 4.1%, while the positivity rate in Regions 4 and 7 of the state’s reopening plan either remained roughly flat or increased as of Aug. 28 despite added restrictions.

Region 7 — which contains Kankakee and Will counties — saw its positivity rate increase to 8.8% as of Friday after new restrictions took effect last Wednesday. In Region 4, which includes the Metro East area on the Missouri border, the positivity rate was 10.4% as of Friday after nearly two weeks of restrictions.

Gov. J.B. Pritzker has said more restrictions can come this week if the positivity rate in the area does not decrease.
