This project addressed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing barriers in rural West Virginia by providing testing enhancements that included (1) a flexible testing staff, (2) mobile testing, (3) essential supplies, and (4) specialized testing in communities of color. A total of 142 775 polymerase chain reaction tests were performed from December 2021 through February 2022; positivity rates were 21% and 17% in clinics and mobile testing venues, respectively. The project results showed that, within a statewide network of health care clinics, administrators quickly identified and distributed enhancements and thus reduced testing barriers.
