With indoor dining returning throughout parts of the Chicago area there is new attention on the state’s system for managing COVID mitigations.

In August the state moved to a system using tiers aimed at giving regions more flexibility. There are three levels between what was previously called phase 3 and phase 4. If key metrics of the coronavirus outbreak — such as test positivity, hospitalizations and available hospital capacity — get better or worse, a region can move forward or backward.

Here is where the regions stand and what is allowed under the guidelines.
