The prospect that we may see the end of AIDS in our lifetime has never been greater. Over the last decade, the global HIV & AIDS community has achieved stunning successes, including a steady decrease in new HIV cases, a massive scale-up of antiretroviral therapy (ART), and proof that treatment is prevention. As we begin the XIX International AIDS Conference, we are also excited by new scientific advances in prevention and treatment, such as Option B+ for prevention of maternal-to-child transmission (PMTCT). As new possibilities develop, we must also build on the successes of the last decade. Only by "turning the tide together" through the simultaneous pursuit of new possibilities, leveraging of proven interventions for scale and sustainability, and strengthening of health systems overall, can we hope to reach our goal of ending the HIV & AIDS epidemic.
