Cook County moves to Tier 1—indoor dining allowed

Information provided by the Illinois Department of Public Health

SPRINGFIELD, Ill. (January 23, 2021) – The Illinois Department of Public Health (IDPH) today announced Region 10 (suburban Cook) and Region 11 (city of Chicago) are moving to Tier 1 effective January 23. Region 10 has been in Tier 2 since January 18.

A notable change for Cook County in Tier 1 is the allowance for restaurants to resume indoor dining at a 25 person or 25% capacity limit. Gatherings are also allowed up to 25 people or 25% of room capacity. Full Tier 1 restrictions can be viewed here.

IDPH will continue to closely monitor test positivity, ICU bed availability, and the number of people in the hospital with COVID-19.  Should data show regions trending in the wrong direction, based on the established mitigation metrics, regions could once again find themselves in a higher tier with increased measures.
