The 90-90-90 target aims to help end the AIDS epidemic by 2020 by having 90% of people living with HIV know their status, 90% of those diagnosed on treatment, and 90% of those on treatment virally suppressed. The target was established by UNAIDS and WHO to drive progress beyond 2015 by setting clear goals. Achieving the target would require increased testing, treatment, and viral load monitoring services especially in sub-Saharan Africa where most people living with HIV lack treatment. Barriers like stigma, remote locations, and costs must also be addressed to achieve the 90-90-90 goals by 2020.
