This study is partnering with communities to identify the best ways to provide COVID-19 testing and vaccines to people who have been disproportionately affected by COVID-19. This includes communities of color, essential workers, immigrants and migrants, people in rural areas, and people with chronic diseases like diabetes and high blood pressure. We want to train community outreach workers and peer recruiters from community and faith-based organizations to help reach these underserved populations with COVID-19 testing and COVID-19 vaccines - a strategy known as "community-based task shifting." Thus, we will be conducting focus groups and theater testing sessions and questionnaires with patients who have received COVID-19 health services and focus groups and interviews with key stakeholders and theater testing sessions and questionnaires with individuals who work in community outreach or peer health education organizations for COVID-19 health services.
