Intensive care unit availability across McHenry and Lake counties dropped again to 20%, the Illinois Department of Public Health reported Wednesday.
ICU care availability had fallen below 20%, a threshold previously used by the state as a trigger point for implementing more strict health mitigations on regions, twice this summer, something that hadn’t occurred during either last year’s fall peak or the more recent spring surge.
The number of people hospitalized in both counties was 91 on Tuesday, one fewer than the day before, the IDPH reported. The region saw the number of patients hospitalized decrease or remain stable nine of the past 10 days.
In McHenry County alone, 4.5% of medical and surgical beds and 26.8% of intensive care unit beds were available, according to the McHenry County health department. Hospitalizations have decreased or remained stable eight out of the past 10 days in McHenry County.
Statewide, the number of hospitalizations tied to COVID-19 fell Tuesday to 1,615, according to the IDPH. Of those, 365 were in the ICU and 197 were on ventilators.
Meanwhile, an additional 63 COVID-19 cases were reported on Wednesday by the McHenry County health department, bringing the total number of cases in the county to 34,359, including 308 deaths and 32 deaths that likely were caused by COVID-19 but could not be confirmed. No additional deaths were reported Wednesday.
The county’s incidence rate remained well above the threshold that the Centers for Disease Control and Prevention considers to mark a “high” transmission of COVID-19.
The number of new cases over the previous seven days fell to 129.67 per 100,000 residents Friday, the most recent day for which data is available, according to the McHenry County health department’s school metrics dashboard.
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 and remain there for a week, according to the county’s health department.
McHenry County’s COVID-19 test positivity rate remained at 2.9% for the third day on Sunday, according to the McHenry County Department of Health. The county has been within the low transmission range of zero percent to 4.9% for more than a month.
Both the CDC and McHenry County health department use the incidence rate and positivity rate to categorize COVID-19 transmission. When the two metrics do not fall within the same transmission risk category, the higher one is chosen, according to the county health department.
Region 9, which is made up of Lake and McHenry counties, had a positivity rate of 2.3% as of Sunday, according to the Illinois Department of Public Health.
The number of McHenry County residents receiving COVID-19 vaccines fell Tuesday, with the seven-day rolling average of administered doses reaching 550, state data showed.
An additional 585 COVID-19 vaccines were administered to McHenry County residents on Tuesday, bringing the total number of doses administered to 357,602, the IDPH reported.
A total of 175,193 county residents, or an estimated 56.78% of McHenry County’s population, now are fully vaccinated, meaning they’ve received all doses recommended for the vaccine they were given.
Statewide, 14,927,266 vaccines have been administered, according to state data.
Across Illinois, 80.9% of those age 12 and older have received at least one vaccine dose, and 63.4% are fully vaccinated, the IDPH reported Wednesday. Those rates are 82.5% and 64.9% for people 18 and older and 96.7% and 78.9% for those 65 and older.
The IDPH reported 2,913 new confirmed and probable cases of COVID-19 statewide on Wednesday. Another 39 deaths also were logged Wednesday, bringing the totals to 1,660,883 cases, 25,327 confirmed deaths and 2,762 probable deaths.
Among McHenry County ZIP codes, Crystal Lake (60014) has the highest number of COVID-19 cases with a total of 5,260 confirmed cases, according to county data. Woodstock (60098) followed with 3,936 cases.
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.
