Metric Guidance and Relevant Data Sources

  • CDC Indicators (Metrics) for School Decision Making
    CDC's Indicators for Dynamic School Decision-Making webpage is pretty informative. The webpage includes both "core" indicators and "secondary" ones, and mitigation strategies. Though CDC has been under political pressure to have students return to in-person learning, these metrics are reasonable and align fairly well to others we have seen. CDC's is a 5 level scale (as opposed to IDPH's 3 [see pg 4 of this document] and Harvard Global Health Institute's 4) ranging from lowest risk of transmission in schools to lower, moderate, higher, and lastly highest.

    Metrics for School Districts to Inform Decision-Making:

    Illinois Department of Public Health (IDPH) distributed this Adaptive Pause and Metrics: Interim School Guidance for Local Health Departments on August 17, 2020. Page 4 of this document contains a chart showing the specific metrics that IDPH developed to define minimal, moderate, and substantial “community transmission.” Below are links to help you access the data you need to see how various geographic regions are performing against these metrics.

    COVID-19 Data:
    Illinois’ 11 Health Regions: It is important to note that suburban Cook County is Region 10 and Chicago is Region 11 and both are distinct regions that do not overlap. This map is a bit more “general” than several of the following ones, which provide more specificity and explanation.

    IDPH County Level COVID-19 Risk Metrics: It is important to note that on this page “Cook” represents suburban Cook County only. Chicago is listed separately.

    These next three links let you drill down by zip code:

    **UPDATED** Cook County Department of Public Health’s Shiny App: This “app” allows you to drill down into the data with greater specificity based on the town you search on the Case Data by Town tab or by hovering your cursor over the interactive map on the Map tab. CCDPH has recently added a School Metrics tab that is not only specific to schools, but further breaks down suburban Cook County into North, West, Southwest and South regions.

    RtCOVID-19: The Rt value indicates the average number of people that one person with COVID-19 is expected to infect. A number higher than one means each infected person is passing the virus to more than one other person. If Rt is above 1.0, the virus will spread quickly. When Rt is below 1.0, the virus will stop spreading.
