COVID infection metrics at heart of school closings

Why it matters: It's not just in CPS. COVID metrics that would tighten safety measures have quietly disappeared in the city and state, too.

• This loss of clear parameters can erode official accountability and predictability for people making decisions in the face of soaring cases and hospitalizations.

Context: While this Illinois site shows metrics used to move the state forward into looser safety measures, it doesn't specifically state what level of infection might send us back.

• Instead it says officials will make recommendations based on current factors.

What they're saying: Illinois Department of Public Health spokesperson Melaney Arnold says the state stopped using the metrics because things have changed.

• Today we have, "Safe and effective vaccines free to everyone, monoclonal antibody treatment… state testing locations now operating 6 days a week, and State staffing contracts to help hospitals address the nationwide health care worker shortage."
