CHICAGO (WBBM NEWSRADIO) -- Illinois health officials reported Friday 4,556 new cases of COVID-19, the highest number of new cases reported by the state throughout the pandemic.
The caseload topped the previous high of 4,105 cases confirmed Thursday - just a day earlier - by the Illinois Department of Public Health.
The new cases were reported among 87,759 tests over the last 24 hours, health officials said. This tops the previous high of 74,286 tests per day on Sept. 19. There were 2,529 newly confirmed cases that day.
An additional 38 deaths attributed to the coronavirus were also reported Friday. Currently, IDPH is reporting a total of 336,174 cases, including 9,165 deaths, in 102 counties in Illinois.
The preliminary seven-day statewide positivity for cases as a percent of total test from Oct. 9 – Oct. 15 is 5.1 percent, surpassing a threshold recommended by the World Health Organization for safely reopening economies, the Tribune reported.
Additionally, 34 counties in Illinois are now at a "warning level" for coronavirus, IDPH said.
According to IDPH, the warning means each of the counties saw increases in two or more COVID-19 "risk indicators."
The counties now under a warning include: Adams, Alexander, Boone, Cass, Christian, Clay, Clinton, Crawford, DeKalb, DeWitt, Jasper, Jefferson, Jo Daviess, Johnson, Kane, Lee, Macon, McDonough, McHenry Mercer, Monroe, Pike, Pulaski, Randolph, Saline, Stephenson, Union, Vermilion, Warren, Washington, Wayne, Whiteside, Will, Winnebago.
Among the metrics evaluated to determine if a county has reached a "warning level" are: new cases per 100,000 people, number of deaths, weekly test positivity, ICU availability, weekly emergency department visits, weekly hospital admissions, tests performs, and clusters.
As of Thursday night, 2,016 people in Illinois were hospitalized with COVID-19. Of those, 410 were in the ICU and 151 were on ventilators.
