Cook County is once again at a high COVID-19 alert level.
The county had dropped from the high to medium level June 16, but a slight increase in hospitalizations reported by the Centers for Disease Control and Prevention on Thursday pushed it back over the CDC’s high threshold.
“We do expect that Cook County will drop back to medium level again next week, but this is a good reminder to make sure that you and everyone you love is up to date with vaccines — including boosters,” Chicago Department of Public Health Commissioner Allison Arwady said.
The county’s levels of new positive COVID-19 cases and new hospitalizations are only slightly above levels designated medium. Per 100,000 people, Cook County is experiencing 202 new cases and 10.2 hospitalizations. The CDC sets high thresholds at 200 new cases and 10 hospitalizations.
Chicago remains in the medium level with fewer new cases and hospitalizations than Cook County. Other city COVID-19 indicators remain stable, city health officials said. DuPage and Lake counties are currently experiencing high transmission rates.

“I know everyone wants COVID to be over,” Arwady said. “Unfortunately, we continue to see the COVID virus itself mutate quickly, with new, more contagious subvariants emerging every few weeks.”
In Chicago, the seven-day average of new cases dropped to 653 on Friday, according to the city’s COVID-19 dashboard. That same figure had been at 832 a week earlier, and during the peak of the omicron surge in January reached nearly 7,000, the highest since the pandemic began in early 2020.
The city’s positivity rate jumped from 6.4 % to 10.7 %, a spike that may be related to a sharp decrease in testing associated with the end of the school year.

The country has seen a slight increase in the number of counties at either high or medium levels over the last week, the Chicago Public Health Department said. The bulk of high and medium level counties are in the West and Florida.
Vaccinations and boosters are strongly advised to guard against serious illness and hospitalization. Children from 6 months to 5 years old are eligible for the vaccine.
