Case positivity and test positivity rate are both relevant and offer insight into the bigger COVID-19 picture. Case positivity helps us understand whether changes in the number of confirmed cases is due to more testing or due to more infections. Test positivity accounts for repeated testing and helps us understand how the virus is spreading in the population over time.

The preliminary seven-day statewide positivity for cases as a percent of total tests from March 8-14, 2021, is 2.2%. The preliminary seven-day statewide test positivity from March 8-14, 2021, is 2.6%.
