This document is a slide presentation on treatment as prevention (TasP) given by Julio Montaner. It discusses how expanded access to antiretroviral therapy (HAART) has led to dramatic declines in HIV mortality, incidence, and transmission in British Columbia. It shows data on decreasing AIDS cases, HIV prevalence and mortality in BC from 1996 to 2011 coinciding with increasing HAART coverage. The presentation argues that TasP is cost-effective and its global implementation could end the AIDS epidemic and save millions of lives. It notes growing international support for TasP from leaders like Obama, Clinton and adoption of TasP approaches in places like China and BC's hosting of the AIDS 2015 conference.
