There were 16,581 new and probable COVID-19 cases recorded within the past 24 hours by the Illinois Department of Public Health. That’s the highest single-day total this year and the highest since November 2020, per IDPH data.

Chicago's updated travel advisory includes 42 states, announced Dr. Allison Arwady, the commissioner of the Chicago Department of Public Health.

The omicron variant of COVID-19, which is believed to be highly transmissible, has been detected in Chicago, state and city health officials announced Tuesday. 

Even as the threat posed by the omicron variant of COVID-19 has yet to materialize in Chicago, the city is enduring a “very significant” surge of COVID-19 fueled by the holiday gatherings and indoor events, Chicago’s top doctor said Tuesday.

Chicago's updated travel advisory includes 38 states, announced Dr. Allison Arwady, the commissioner of the Chicago Department of Public Health.

One week after it was removed from the advisory, officials returned Arkansas to the list of states with high rates of transmission. The advisory includes 38 states as well as Guam, announced Dr. Allison Arwady, the commissioner of the Chicago Department of Public Health.

While the COVID-19 vaccine has now been approved for younger children, Chicago could find itself in the midst of another coronavirus surge this winter if families wait too long to get their children vaccinated, the city’s top doctor said Tuesday.

Chicago officials removed Arkansas from the city’s COVID-19 travel advisory Tuesday even as confirmed cases of COVID-19 continue to rise in Chicago as colder weather blanketed the city. 

The advisory continues to cover 41 states as well as Guam, announced Dr. Allison Arwady, the commissioner of the Chicago Department of Public Health. 

The city is poised to get nearly 100,000 doses of the Pfizer vaccine for kids during the first week after the vaccine is authorized, officials said. 

City officials removed Georgia, Louisiana, Maryland and Mississippi from the travel order, joining Florida, Hawaii, California, Connecticut, Washington, D.C. and Puerto Rico.

Cook County Judge Cecilia Horan on Monday evening denied a request seeking to extend a temporary restraining order against John Catanzara, who had repeatedly urged Fraternal Order of Police members not to give their vaccination status to Chicago officials.

The advisory now covers 45 states as well as Guam and the Virgin Islands, officials said.

Fraternal Order of Police President John Catanzara's actions and rhetoric "threatens the health and safety of Chicago’s residents and first responders," Mayor Lori Lightfoot said.

But with a week to go until her declared deadline, Mayor Lori Lightfoot stepped back and said she would not discipline unvaccinated employees. 

The city’s travel advisory now covers 47 states as well as Washington, D.C., Guam and the Virgin Islands, officials said Tuesday.
