Marion County is one of 24 counties in Illinois to be placed at a warning level Friday for COVID-19.

A total of 24 counties were placed on the list Friday, including Bond, Clinton, Effingham, and Washington counties.

Of the 24 counties placed on the warning list, Marion County has the lowest positivity rate of 8.5 percent for the period between September 6 and September 12. The highest positivity rate for that same period is Crawford County at 24.3 percent.

Clinton County remains on the list from last week. Its positivity rate for the latest reporting period is 17.6 percent, Bond County is at 11.3 percent, Effingham County at 11.4 percent, Washington County at 11 percent, and Wayne County’s positivity rate is now 15.7 percent.

IDPH uses numerous indicators when determining if a county is experiencing stable COVID-19 activity, or if there are warning signs of increased COVID-19 risk in the county.  A county is considered at the warning level when at least two of the following metrics triggers a warning.

New cases per 100,000 people, number of deaths, weekly test positivity, ICU availability, weekly emergency department visits, weekly hospital admissions, number of tests performed, and clusters.

Marion, Clinton, and Washington counties all reached warning level on the number of new cases, weekly test positivity and number of tests performed.
