Illinois is broken down into 11 health care regions, which the state used to determine which areas can begin lifting some coronavirus restrictions.
Illinois Gov. J.B. Pritzker announced Friday that three of the state's regions can lift Tier 3 coronavirus mitigations effective immediately, with most of the others on track to move into the less restrictive Tier 2 in the coming days.
Which counties are in each region? Here's a breakdown:
- NORTH: Boone, Carroll, DeKalb, Jo Daviess, Lee, Ogle, Stephenson, Whiteside, Winnebago
- NORTH-CENTRAL: Bureau, Fulton, Grundy, Henderson, Henry, Kendall, Knox, La Salle, Livingston, Marshall, McDonough, McLean, Mercer, Peoria, Putnam, Rock Island, Stark, Tazewell, Warren, Woodford
- WEST-CENTRAL: Adams, Brown, Calhoun, Cass, Christian, Greene, Hancock, Jersey, Logan, Macoupin, Mason, Mason, Menard, Montgomery, Morgan, Pike, Sangamon, Schuyler, Scott
- METRO EAST: Bond, Clinton, Madison, Monroe, Randolph, St. Clair, Washington
- SOUTHERN: Alexander, Edwards, Franklin, Gallatin, Hamilton, Hardin, Jackson, Jefferson, Johnson, Marion, Massac, Perry, Pope, Pulaski, Saline, Union, Wabash, Wayne, White, Williamson
- EAST-CENTRAL: Champaign, Clark, Clay, Coles, Crawford, Cumberland, De Witt, Douglas, Edgar, Effingham, Fayette, Ford, Iroquois, Jasper, Lawrence, Macon, Moultrie, Piatt, Richland, Shelby, Vermillion

The state was divided in the 11 separate regions in July to allow health officials to apply a more focused approach to each area's coronavirus response as the pandemic continues.
Any restrictions imposed or mitigation efforts applied to slow the spread of the coronavirus will be done so in each of these specific regions individually moving forward, Pritzker said in announcing the regions.
All of Illinois' 11 regions have been under Tier 3 mitigations since Nov. 20, suspending indoor dining across the state and closing down museums and casinos.
The three regions that can immediately move into Tier 2 include: Region 1, Region 2 and Region 5.
Under the state's guidelines, a region can move to Tier 2 mitigations if it sees a test positivity rate less than 12% for three consecutive days and more than 20% of ICU and hospital beds are available, as well as declining COVID-19 hospitalizations in seven of the previous 10 days.
The move to Tier 2 will mean the return of group fitness classes and lower-risk youth and recreational sports, and the reopening of cultural institutions like museums, with a 25% capacity limit, among other things.
Regions with a positivity rate averaging between 6.5 percent and 8 percent, will likely be under Tier 1 guidelines, though the state could still choose to monitor before lifting restrictions further.
To move to Phase 4, however, the positivity rate must average less than or equal to 6.5 percent over a 3-day period.
