The McHenry County Department of Health on Monday reported another 183 new COVID-19 cases recorded since Friday’s update.
Total cases in McHenry County now number 32,491, including 301 deaths and 30 deaths that likely were caused by COVID-19 but could not be confirmed. No additional deaths were reported Monday, and the county’s recovery rate remains at 99%.
The county’s incidence rate – the number of new cases in the past seven days per 100,000 residents – was 147.86 per 100,000 residents as of Wednesday, the most recent day for which data is available, according to the McHenry County health department’s school metrics dashboard.
That’s well above the threshold for designating transmission as “high” set by the Centers for Disease Control and Prevention. For spread to meet the less severe category “substantial,” the incidence rate would need to fall below 100 new cases over seven days per 100,000 residents.
McHenry County’s positivity rate was 4.6% as of Friday, the ninth day it has been within the low transmission range of 0% to 4.9%. The positivity rate is measured by a seven-day rolling average with a three-day lag.
According to the Illinois Department of Public Health, Lake and McHenry counties, which make up Region 9, have a positivity rate of 4.3% as of Friday.
Both the CDC and McHenry County health department use the incidence rate and positivity rate to categorize COVID-19 transmission.
When the positivity rate and incidence rate do not fall within the same transmission risk category, the higher one is chosen, according to the McHenry County health department.
Meanwhile, an additional 1,328 COVID-19 vaccines were administered to McHenry County residents over Friday, Saturday and Sunday, bringing the total number of doses administered to 341,959, IDPH reported.
A total of 168,591 county residents, or an estimated 54.64% of its population, now are fully vaccinated, meaning they’ve received all the doses recommended for the vaccine they were given.
Statewide, 14,208,557 vaccines have been administered, according to state data.

Intensive care unit availability across McHenry and Lake counties dipped to 19%, below the 20% benchmark for the first time in eight days.

The McHenry County health department reports ZIP code data only for parts within McHenry County, a department spokeswoman said. Any discrepancies between county and IDPH numbers likely are because of the data’s provisional nature and because each health department finalizes its data at different times, she said.
