All 102 counties in the state of Illinois are currently experiencing “high transmission” levels of COVID-19, while many are also experiencing dramatic growth in other metrics designed to illustrate how rapidly the virus is spreading.
The Centers for Disease Control and Prevention considers a county to have a “high transmission” rate of COVID if 100 or more residents per 100,000 individuals have contracted the virus in a given week.
Currently, all 102 of Illinois’ counties have hit that threshold, according to the latest data from IDPH and the CDC, and no state is currently lower than 208 cases per 100,000 residents.
Piatt County, located just to the west of Champaign County, is reporting one of the state’s highest totals, with 881.06 cases per 100,000 residents in the last week.
That is nearly nine times more than the CDC’s “high transmission” threshold, and the county’s positivity rate is also above 10%, according to IDPH data.
Cook County has one of the lowest positivity rates in the state, currently sitting at 4.15% in the last week.
That mark is nearly three times higher than the “high transmission” threshold from the CDC, but is also one of the lowest rates in the state.
