The International HIV Treatment as Prevention Workshop is an annual meeting that brings together academic, policy, industry, and community representatives to review and discuss research and policy progress in the field of HIV treatment as prevention.

First held in 2011, the Treatment as Prevention Workshop is hosted by the BC Centre for Excellence in HIV/AIDS, and co-hosted by the International AIDS Society, Joint United Nations Program on HIV/AIDS, World Health Organization, and National Institute on Drug Abuse.

The Treatment as Prevention Workshop is a single track meeting with daily plenary, debates, oral abstract, and poster sessions. Each oral session has abundant time dedicated to open discussion, providing an opportunity for participants to share their experience to date, as well as protocols, preliminary findings, and future plans and needs.
