CDC K-12 School Metrics for Arlington

The Centers for Disease Control (CDC) have published a set of Indicators for Dynamic School Decision Making to help guide decisions related to school programming. These are published on the Virginia Department of Health website. The Virginia Department of Education in collaboration with the Virginia Department of Health published a Decision Matrix for using these indicators here. Here are the key Arlington metrics we are following.

*Total number of new cases per 100,000 persons within the last 7 days is calculated by adding the number of new cases reported in the last 7 days, dividing by the population of that locality, and multiplying by 100,000.  The indicator differs from the daily case incidence rate per 100,000 used by VDH in the Daily Region Metrics dashboard because it captures the case incidence for 7 days rather than one day.

**Percentage of NAAT tests in the locality that are positive during the last 7 days is calculated by dividing the number of positive tests over the last 7 days by the total number of tests conducted over the last 7 days and multiplying by 100.

†Percent change in new cases per 100,000 population during the last 7 days compared with the previous 7 days is calculated by adding the number of new cases reported in the locality in the last 7 days, subtracting the total number of new cases in the previous seven days, dividing the difference by the total number of new cases in the previous seven days, and multiplying by 100.  In communities with low case incidence, this measure can fluctuate wildly.

‡Hospitalization data are provided at the region level.  The CDC Indicators for Dynamic School Decision-Making also includes a measure of the percentage of intensive care unit beds in the community that are occupied. VDH can not currently calculate this measure as the total census of ICU beds is not available.

§In this document CDC defines community outbreak as a sudden increase in the number of COVID-19 cases.  VDH uses the national CSTE COVID-19 outbreak definitions (CSTE). Because of the difference in definitions, VDH did not create a separate outbreak metric using this CDC definition.

¹Compliance with health and safety measures is calculated by the number of failed audits and complaints of non-compliance, divided by the total number of schools operating, multiplied by 100.

²N/A on Live Report denotes pending further information from the employee or family.  Dashboard adjustments for duplicate reporting occurs frequently.
