In 2013, the UNAIDS conducted stakeholder consultations in all regions of the world for new targets to update those that were set for 2015. This resulted in the new, ambitious targets:
By 2020, 90% of all people living with HIV will know their HIV status.
By 2020, 90% of all people with diagnosed HIV infection will receive sustained antiretroviral therapy.
By 2020, 90% of all people receiving antiretroviral therapy will have viral suppression.
The document in the link explains why new targets are needed, the basis for these targets and the key challenges to overcome process of defining those new targets.
Evidence from HIV programs, especially that referring to the loss of patients across the HIV treatment cascade has given emphasis on the key role of service quality and outcomes of programs in delivering antiretroviral therapy. The new targets also focus strongly on key populations using rights based approaches. Challenges such as catching up in settings with low service coverage, societal challenges, delivery challenges and costs are also addressed in the document. Find the complete document here
