CHICAGO – Chicago and Cook County remain at the Medium COVID-19 Community Level according to the latest Community Level metrics released by the Centers for Disease Control and Prevention (CDC). Chicago could, however, reach the High Level with a post-holiday infection surge, and CDPH continues to urge everyone to get their booster shots and mask in crowded indoor spaces.  

“While I’m pleased that Chicago remains in the Medium Level, we expect this could soon change, especially with many people attending more large gatherings over the next few days,” said CDPH Commissioner Allison Arwady, M.D. “As Chicagoans gather to ring in the New Year this weekend, it’s important we all stay on the defense against COVID-19 and the flu. 

“Pleaes make sure you have had both your flu shot and your fall 2022 COVID booster,” said Dr. Arwady. “Beyond that, if you are going to be in crowded indoor spaces this weekend, think about putting your mask on, knowing many viruses are circulating right now in Chicago--and if you’re feeling sick, please stay home.” 

Those who host New Year’s gatherings can do many things to reduce the risk of COVID-19 for revelers. Encourage people to test for COVID-19 before gathering, especially if there will be people who are older or immune-compromised attending. Improving ventilation can also help reduce virus particles and keep COVID-19 from spreading. This is as simple as cracking open a window, turning on a fan, or using air filters. With relatively mild winter weather this weekend, conditions will be good to improve ventilation in your home.  

The CDC has tips for improving the ventilation in your home on their website.

Upcoming Vaccine Events 

CDPH continues to urge all Chicagoans age 6 months and older to remain up to date on COVID-19 vaccinations, including the fall 2022 booster, and to get their annual flu shot. The flu can bring serious illness for younger people, older people, especially those who have not gotten a flu shot. The updated COVID booster vaccine is free for all, regardless of health insurance status.  

The City continues to operate Protect Chicago At Home, its completely free program that will bring COVID-19 and flu vaccines right to any Chicagoan’s home and vaccinate up to 10 people in a single appointment. CDPH has administered more than 22,000 COVID vaccinations through the At Home program.  

COVID-19 vaccines, including primary doses and the new booster vaccines are available for anyone age 6 months and up through the At Home program. Chicagoans age 6 months and up can also receive a flu vaccine at home if at least one member of the household is receiving a COVID-19 vaccine. Appointments are available mornings, afternoons, evenings, weekdays, and weekends. Make an at-home appointment for your family at or by calling (312) 746-4835.  

Starting Saturday, January 7, CDPH will again be operating Family Vaccination Clinics at six City Colleges of Chicago sites throughout the City. The vaccination clinics will run every Saturday through February 11, offering flu shots, COVID-19 vaccines, and the updated bivalent booster to all eligible Chicagoans. Sites operate 9am-2pm: 

  • Saturday, January 7 at Malcolm X College, 1900 W. Jackson Blvd.
  • Saturday, January 14 at Richard J. Daley College, 7500 S. Pulaski Rd. 
  • Saturday, January 21 at Olive Harvey College, 10001 S. Woodlawn Ave.

COVID-19 Bivalent Booster Updates 

As of December 28, 18.8 percent of all Chicagoans age 5 and up have received the updated COVID booster vaccine, compared to 15.1 percent of all Americans. One in five Chicago adults 18 and older have received a bivalent booster. As of December 28, more than 507,000 doses of the updated booster have been administered to Chicagoans.  

This new, updated vaccine, known as the bivalent booster, is designed to better protect against Omicron subvariants as well as original strains of the virus. The bivalent booster generates a stronger immune response against current and future Omicron subvariants.  

COVID-19 By the Numbers 

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. The Levels were developed to help communities decide what prevention steps to take based on the latest local COVID-19 data.   

CDPH also 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. Visit for the Chicago COVID-19 daily data dashboard.
