Here’s where each health region in northern Illinois stands as of Sunday for new cases and vaccine administration

The Illinois Department of Public Health reported 4,162 new confirmed and probable cases of COVID-19 and 29 additional deaths Sunday, and a total of 487,040 COVID-19 vaccines have been administered.

The seven-day rolling average of Illinois’ positivity rate decreased from 6.3% to 6.1%. The state received the results of 96,845 COVID-19 tests in the 24 hours leading up to Sunday afternoon.

Illinois has seen 1,068,829 total cases of the virus, and 18,208 people have died. The state has conducted a total of 14,763,993 tests since the start of the pandemic.

As of late Saturday, Illinois had 3,408 COVID-19 patients in the hospital. Of those, 720 were in intensive care units, and 387 were on ventilators.

On Sunday, the IDPH announced that Region 2, covering much of North-Central Illinois, is now meeting all of the metrics necessary to move into Tier 1, which is the least restrictive of the three tiers of mitigation measures and allows for limited indoor dining.

Region 2 joins Southern Illinois’ Region 5 in Tier 1. Region 1, which covers the northwest portion of the state, is in Tier 2. The state’s remaining eight health regions are all in Tier 3, the strictest of the three tiers.

Vaccine update: As of Sunday, IDPH reported a total of 1,049,675 doses of COVID-19 vaccines have been distributed statewide, with 487,040 vaccines administered.

As of the time this story was published, 104,928 people in Illinois have been fully vaccinated, or 0.82% of the population. Illinois has a population of 12,741,080 people.

There can be as much as a 72-hour delay in reporting from healthcare providers on vaccines administered.

In northern Illinois, here is the percentage of the population fully vaccinated by county:

Chicago: 0.84%

Suburban Cook: 0.87%

Lake: 0.80%

Regional update: Currently, all 11 of the state’s health regions are under additional mitigation measures from the IDPH, and as of Nov. 20, all 11 regions are under Tier 3 mitigations. Regions are eligible to move forward to Tier 2 beginning Friday, Jan. 15, as long as they hit all three of the state’s metrics.

The three metrics needed for a region to advance to Tier 2 are:

1) A region’s test positivity below 12% for three straight days (as measured by a seven-day rolling average)

2) 20% or greater available staffed ICU and medical/surgical beds for three straight days (as measured by a three-day rolling average)

3) A decline in number of people hospitalized with COVID-19 for 7 out of 10 days (as measured on a seven-day average.)

Regional data from the IDPH remains on a three-day lag.
