The vast majority of those newly diagnosed have spent time in the criminal legal system. Individuals under criminal legal supervision, especially jails because of the shorter lengths of stay and frequent re-entry into the community, are a high-risk group for contracting HIV and are therefore, an ideal target population for pre-exposure prophylaxis (PrEP). This study’s findings will inform the development of HIV prevention strategies, primarily via PrEP, for men that have been incarcerated in jail. Under general supervision of Principal Investigator, executes protocols for clinical research studies. Conducts subject interviews and/or visits including administering questionnaires, performing anthropometrics and collecting samples or data. Coordinates screening, scheduling and enrollment of subjects. Assists in designing strategies for recruitment and community outreach. May oversee data collection and training of new employees and/or student assistants.
