CDPH COVID-19 Update: Chicago and Cook County Drop to Medium COVID-19 Community Level Based on CDC Metrics

June 16, 2022

COVID-19 Joint Information Center

CHICAGO – Chicago and Cook County moved into the Medium COVID-19 Community Level from High today based on the latest data from the Centers for Disease Control and Prevention (CDC), reflecting a dropping number of new cases and lower hospitalization rates in the region for COVID related illness.

“We have been trending in the right direction of late with lower case rates and very few hospitalizations and deaths from COVID-19, so we’re happy to see this,” said CDPH Commissioner Allison Arwady, M.D. “But COVID-19 is still with us. We continue to recommend masking indoors and that the medically vulnerable in particular continue to take precautions to protect themselves from infection. We’re not close to being out of this yet.”

The CDC determines COVID-19 Community Levels as Low, Medium, or High, based on the number of new local COVID-19 cases, regional COVID-19 hospital admissions, and COVID-19 hospital capacity in the prior week. They were developed to help communities decide what prevention steps to take based on the latest local COVID-19 data. Travelers should review CDPH’s travel guidance and check the CDC map to know whether the areas they are visiting are Low, Medium, or High risk for COVID-19 and take proper precautions. The CDC recently announced that international travelers to the U.S. are no longer required to show proof of a negative COVID-19 viral test before boarding their flight to the U.S.

When the CDC updates its COVID-19 Community Levels national map each week, the City of Chicago and suburban Cook County data are combined into one weekly case metric for Cook County. Hospitalization data, in contrast, reflect a burden on the whole federally defined Health Service Area, which includes hospitals in Cook, Lake, DuPage, and McHenry counties. CDPH continues to track and report COVID-19 hospital burden specifically for Chicago hospitals every day on its dashboard and uses this local hospital data to make further mitigation decisions.

Based on the latest data from CDC, Cook County levels are as follows.  


New Cases (per 100,000 people in last 7 days)

New COVID-19 admissions per 100,000 population (7-day total)

Proportion of staffed inpatient beds occupied by COVID-19 patients (7-day average)

  [GOAL is <200] [GOAL is
[GOAL is <10%]
Cook County (including City of Chicago) 221.06 9.8 3.5%
Cook County metrics are calculated by the CDC and posted on the CDC Community Levels website (data as of 6/16/2022). 


Chicago data will be updated on CDPH’s website at 8 a.m. tomorrow.
