To study the use of long-acting injectable antiretroviral therapy (LAI) among a racially, economically, and geographically diverse group of persons with HIV

To test the pay-it-forward strategy as a means of increasing rates of testing for gonorrhea

To provide a much-needed characterization of Lassa fever epidemiology and pathogenesis, and to determine the duration and infectivity of genital fluids from survivors that will provide a wellspring of data to inform public policy and individual care.

The purpose of this research study is to learn more about patient preferences for care when undergoing treatment for drug use-associated endocarditis (DUA-IE), specifically treatment for addiction and antibiotic treatment.

To learn about more effective ways the health care system in Zambia can care for people with non-communicable diseases (NCDs) who are also living with HIV.

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.
