Coronavirus Positivity Rate Rises In Lake-McHenry County Region

WAUKEGAN, IL — Coronavirus positivity rates have increased over the in the second week of August for all but two of the 11 state's regions. The news comes as state public health officials declare a pair of suburban Chicago counties at a warning level for COVID-19 for the first time.

In the North Suburban Region, which includes Lake and McHenry counties, average positivity rates were up by 1.6 percentage point between Aug. 5 to Aug. 11, the most recent day where data is available.

New hospitalizations — measured by the Illinois Department of Public Health using a rolling average of new "COVID like illness admissions" and rounded to the nearest person — were down slightly but still above rates from two weeks ago.

Illinois officials set an 8-percent positivity threshold for triggering new restrictions, and a rate below 5 percent indicates an adequate number tests are being conducted, according to Johns Hopkins University.

Public health officials Friday announced 14 counties were considered to be at a warning level for a surge of COVID-19 cases, including Bureau, Cass, Clinton, Franklin, Greene, Grundy, Hancock, Jefferson, Kane, LaSalle, Moultrie, Perry, Union and Will counties.

The list includes 10 new counties — including two in the Chicago suburbs — as well as four that were among the 13 at a warning level a week earlier.

The state also reported the highest number of new coronavirus cases in a single day since May, with more than 2,200 new infections detected. As of late Thursday, there were 1,612 people hospitalized with COVID-19 across Illinois. They included 345 people in intensive care units and 126 people on ventilators, according to state health officials.

Gov. J.B. Pritzker's administration has established 11 regions for coronavirus mitigation purposes. Outside the Chicago suburbs, they align with existing emergency medical services regions. Collar counties are paired in their own regions and Cook County is divided into the city and suburbs.

There are two thresholds established that trigger increased restrictions on a regional level.

One is three days in a row with an average positivity rate of 8 percent or more.

The Edwardsville region exceeded the threshold for the first time on the most recent day where data is available. In northern Illinois, the Will-Kankakee region has the highest positivity rate at 6.7 percent. The Rockford and Champaign regions were the only ones to see declines in positivity over the past week.

The other is the combination of seven days of increasing average positivity rates out of the past 10 days plus either hospital bed availability falling below 20 percent in the region or seven days out of 10 with an an increasing rounded average number of new hospital admissions.

The Edwardsville region has 29 percent of surgical beds available. The other regions with the lowest percentage of available beds available — Chicago and suburban Cook County — also have the most total beds.
