COVID-19 hospitalizations in McHenry, Lake counties decrease from a pandemic high

The level of COVID-19 transmission in McHenry County remained high Tuesday, the McHenry County Department of Health reported.

The county health department reported 2,455 new cases of COVID-19 since Friday, but no additional deaths. That brings the total to 58,771, including 377 deaths and 36 deaths that likely were caused by COVID-19 but have not been confirmed.

The county has recorded two COVID-19 deaths so far in 2022.

The test positivity rate for the county, as measured by a seven-day rolling average, increased to 19.9% Saturday, according to the Illinois Department of Public Health.

The region including both Lake and McHenry counties saw its test positivity rate increase Saturday to 15.8%.

McHenry County’s incidence rate increased to 973.63 new cases over seven days per 100,000 residents as of Thursday, the last day for which data was reported, according to the McHenry County health department.

That remains below the peak on Jan. 9, which was the highest the county had seen over the previous 250 days, the time period published by the county, but remains almost 10 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 would need to be below 10%, according to the McHenry County health department. Both metrics would then need to stay below those levels for a week.

The number of people hospitalized with COVID-19 in McHenry and Lake counties decreased to 394 Monday following a high for the pandemic of 407 on Saturday, the IDPH reported.
