The world has embraced the UNAIDS 90–90–90 treatment target, whereby 90% of people living with HIV know their HIV status, 90% of people who know their HIV-positive status are accessing antiretroviral treatment, and 90% of people on treatment have suppressed viral loads. By reaching the 90–90–90 treatment target by 2020, the world will be firmly on track towards ending the AIDS epidemic by 2030.

HIV treatment saves lives and makes the overall AIDS response stronger. Owing primarily to wider access to HIV treatment, AIDS-related deaths globally declined by 42% from 2004 to 2014. Studies have also directly correlated improved access to HIV treatment with reductions in HIV-related stigma and discrimination and a substantial body of evidence indicates that antiretroviral therapy is a pillar of HIV prevention. Countries that have scaled up HIV treatment the fastest over the past decade have achieved the sharpest reductions in new HIV infections.
