HIV treatment is a cornerstone of the AIDS response, helping to prevent AIDS-related deaths and avert new infections. It also helps people living with HIV to live close-to-normal lifespans, thereby reducing HIV-related stigma. Evidence shows that HIV treatment, administered ideally as soon as possible after diagnosis, not only slows disease progression but also prevents onward HIV transmission. Moreover, the right to the highest attainable standard of health necessitates access to treatment and other medicines to ensure that people living with HIV can have long and productive lives.
