Dr. Rosemarie Martin's "COVID-19 Testing and Prevention in Correctional Settings" (3UG1DA050072-02S3, MPI) funded under the National Institutes of Health’s Rapid Acceleration of Diagnostics-Underserved Populations (RADx-UP) initiative prepares to ship 90,000 COVID-19 Ag Card rapid antigen test to correctional facilities in Minnesota, Washington State, Florida, and Rhode Island. This project aims to develop strategies to reduce disparities in COVID-19 testing, examine testing patterns in correctional settings and collect data on disparities in infection rates, disease progression, and outcomes in these settings.
