Archived: Percentage of Positive Tests
These graphs include COVID-19 data through March 26, 2021, prior to the reorganization of the data section of this website.
Test positivity can be a helpful indicator of COVID-19 transmission in your community. If a higher percentage of tests come back positive for COVID-19, that likely means there is more virus circulating in the area. A lower positivity rate likely means less viral transmission.
How should I interpret the numbers?
Levels of positivity are grouped as follows:
- Red: greater than 10%
- Yellow: 5-10%
- Green: less than 5%
These graphs show the percentage of COVID-19 tests that were positive in residents of each county since early June. These statistics include specimens collected from a range of providers, including public health, private physicians, urgent care centers, and hospitals.
