McHenry County reports 3,062 new COVID-19 cases as region’s hospitalizations for virus break records

No new deaths reported, but just 11% of ICU beds are available in McHenry County

McHenry County’s risk of COVID-19 transmission remained high Monday because of both its positivity rate and incidence rate as area hospitals face record numbers of patients with the virus while the pandemic surges.

County health officials reported 3,062 new cases of COVID-19 Monday, the latest update to the data since Thursday’s update. No new deaths were recorded.

That brings the total number of cases to 53,709, including 353 deaths and 35 deaths that likely were caused by COVID-19 but have not been confirmed

The test positivity rate for the county, as measured by a seven-day rolling average, was 21.9% on Friday, down slightly since it reached the highest it has ever been during the pandemic last week, according to the Illinois Department of Public Health.

McHenry County’s incidence rate hit a peak of 912.86 new cases over seven days per 100,000 residents as of Wednesday, the last day for which data was reported, according to the McHenry County Department of Health.

That’s the highest the county has seen over the previous 250 days, the time period published by the county, and more than nine times the threshold set by the Centers for Disease Control and Prevention to indicate a high level of transmission within a community.

For transmission risk 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 the positivity rate below 10%, according to the McHenry County health department. Both metrics would then need to stay below those levels for a week.

The region including both Lake and McHenry counties saw its test positivity rate drop Friday to 18.6%, down from a record rate of more than 19% last week.

Hospital intensive care unit availability across McHenry and Lake counties remained at 16% Sunday, marking the 12th straight day below the 20% threshold previously used by the state as a trigger point for imposing stricter health mitigations.

Overall, the seven-day average of COVID-19 hospitalizations increased every day since Dec. 26 in the two-county region, reaching 382 Sunday to set a new record-high for hospitalized patients, state data shows.

In McHenry County alone, 3% of medical and surgical hospital beds remain available on average, according to the seven-day rolling mean reported Monday by the McHenry County Department of Health. An average of 11% of ICU beds were available.

Hospitalizations for COVID-19-like illness have decreased or remained stable for five of the past 10 days in the county as of Monday.

Statewide, the number of hospitalizations tied to COVID-19 decreased Sunday to 7,114, the IDPH reported. Of those hospitalized, 1,139 patients were in the ICU and 644 were on ventilators.

An additional 4,004 doses of the COVID-19 vaccine were administered to McHenry County residents since Friday’s report, according to the IDPH, bringing the total number administered locally to 472,965. The state reported that 83,415 booster shots were administered in McHenry County.

A total of 190,969 county residents, or an estimated 61.89% of McHenry County’s population, now are fully vaccinated, meaning they’ve received all doses recommended for the vaccine they were given.

Statewide, 19,686,548 vaccines have been administered, according to state data.

Across Illinois, 77.9% of those age 5 and older have received at least one dose of a vaccine against COVID-19, and 68.8% are fully vaccinated, the IDPH reported Monday. Those rates are 82.2% and 73.3% for those age 12 and older, 83.8% and 74.8% for people 18 and older, and 95% and 86.9% for those 65 and older, respectively.

Statewide, the IDPH on Monday tallied 77,833 total new cases of COVID-19 since Friday’s update. Another 207 deaths also were logged since Friday, bringing the totals to 2,460,270 cases, 28,568 confirmed deaths and 3,348 probable deaths.

Neighboring Lake County’s health department reported a total of 96,625 cases and 1,170 deaths as of Sunday. To the south, Kane County’s health department reported 95,004 cases and 959 deaths as of Saturday.

Among McHenry County ZIP codes, Crystal Lake (60014) has the highest number of COVID-19 cases with a total of 8,442 confirmed, according to county data. McHenry (60050) follows with 6,061.

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.
