CDC Releases Indicators for Dynamic School Decision-Making Infographic

Indicators for Dynamic School Decision-Making Graphic

Indicators: Number of new cases per 100,000 persons within the last 14 days*

  • Lowest Risk of Transmission: <5
  • Lower Risk of Transmission: 5 to <20
  • Moderate Risk of Transmission in Schools: 20 to <50
  • Higher Risk of Transmission in Schools: 50 to ≤200
  • Highest Risk of Transmission in Schools: >200

Indicators: Percentage of RT-PCR test that are positive during the last 14 days**

  • Lowest Risk of Transmission: <3%
  • Lower Risk of Transmission: 3% to <5%
  • Moderate Risk of Transmission in Schools: 5% to <8%
  • Higher Risk of Transmission in Schools: 8% to ≤10%
  • Highest Risk of Transmission in Schools: >10%

Indicators: Ability of the school to implement 5 key mitigation strategies:

  • Consistent and correct use of masks
  • Social distancing to the largest extent possible
  • Hand hygiene and respiratory etiquette
  • Cleaning and disinfection
  • Contact tracing in collaboration with local health department

 

  • Lowest Risk of Transmission: Implemented all 5 strategies correctly and consistently
  • Lower Risk of Transmission: Implemented all 5 strategies correctly but inconsistently
  • Moderate Risk of Transmission in Schools: Implemented 3-4 strategies correctly and consistently
  • Higher Risk of Transmission in Schools: Implemented 1-2 strategies correctly and consistently
  • Highest Risk of Transmission in Schools: Implemented no strategies

*Number of new cases per 100,000 persons within the last 143 days is calculated by adding the number of new cases in the county (or other community type) in the last 14 days divided by the population in the county (or other community type) and multiplying by 100,000.

**Percentage of RT-PCR tests in the community (e.g., county that are positive during the last 14 days is calculated by dividing the number of positive test over the last 14 days by the total number of test resulted over the last 14 days. Diagnostic tests are viral (RT-PCR) diagnostic and screening laboratory tests (excludes antibody testing and PT-PCR testing for surveillance purposes).
