Thirty-four counties in Illinois are now at a "warning level" for coronavirus, the state's health department said Friday
The warning means each of the counties saw increases in two or more COVID-19 "risk indicators," the health department said.
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.
Last week, 26 counties were at a "warning level." The week before that it was 28.
"Although the reasons for counties reaching a warning level varies, some of the common factors for an increase in cases and outbreaks are associated with university and college parties as well as college sports teams, large gatherings and events, bars and clubs, weddings and funerals, family gatherings, long-term care facilities, correctional centers, schools, and cases among the community at large, especially people in their 20s," the Illinois Department of Public Health said in a statement.
IDPH said officials observed businesses "blatantly disregarding mitigation measures, people not social distancing, gathering in large groups and not using face coverings."
"Mayors, local law enforcement, state’s attorneys and other community leaders can be influential in ensuring citizens and businesses follow best practices," IDPH added.
Among the metrics evaluated to determine if a county has reached a "warning level" are:
• New cases per 100,000 people. If there are 50 or more new cases per 100,000 people in the county, this triggers a warning.
• Number of deaths. This metric indicates a warning when the number of deaths increases more than 20% for two consecutive weeks.
• Weekly test positivity. This metric indicates a warning when the 7-day test positivity rate rises above 8%.
• ICU availability. If there are fewer than 20% of intensive care units available in the region, this triggers a warning.
• Weekly emergency department visits. This metric indicates a warning when the weekly percent of COVID-19-like-illness emergency department visits increase by more than 20% for two consecutive weeks.
• Weekly hospital admissions. A warning is triggered when the weekly number of hospital admissions for COVID-19-like-illness increases by more than 20% for two consecutive weeks.
• Tests perform. This metric is used to provide context and indicate if more testing is needed in the county.
• Clusters. This metric looks at the percent of COVID-19 cases associated with clusters or outbreaks and is used to understand large increase in cases.
Illinois health officials on Friday reported 4,554 new coronavirus cases, a record high one-day total, as well as 38 additional deaths.
