The 2-day workshop on ARV-based prevention strategies convened a select group of approximately 20-25 invited stakeholders in San Francisco who have interest in and/or play a role in policy, programming, and implementation issues around ARV-based prevention. Invitees included researchers, advocates, public health officials, and service providers, among others. The aim of the workshop was to provide participants with a range of future scenarios and potential strategies which link to goals and objectives for prevention programming. Drawing on the evidence base for ARV-based prevention already collected by the Mapping Pathways project, as well as each other’s knowledge and experience, participants developed a set of pathways they could take back to their communities and policy bodies for discussion and, if appropriate, implementation.
