*Total number of new cases per 100,000 persons within the last 14 days is calculated by adding the number of new cases reported in the locality (city or county) in the last 14 days, dividing by the population of that locality, and multiplying by 100,000. This indicator differs from the daily case incidence rate per 100,000 used in the Daily Region Metrics dashboard because it captures the case incidence for 14 days rather than just one day.
**Percentage of RT-PCR tests in the locality that are positive during the last 14 days is calculated by dividing the number of positive tests over the last 14 days by the the total number of tests conducted over the last 14 days and multiplying by 100. Testing data are provided at the locality level with the exception of Covington, Emporia, Lexington, and Manassas Park. Based on how laboratory results are reported, data from these small jurisdictions are not trustworthy on their own. The surrounding counties of Alleghany, Greensville, Rockbridge, and Prince William are displayed instead.
