The BBS-lite (bio-behavioural survey “lite”) is a programme-based survey methodology for gathering actionable information on people from key populations to improve service delivery and guide decisions on programming for HIV, viral hepatitis and sexually transmitted infections.

Adopted by United Nations Member States in June 2021, alongside ambitious targets for primary prevention and supporting
enablers, the 95–95–95 HIV testing, treatment and viral suppression targets aim to close gaps in HIV treatment coverage and
outcomes in all sub-populations, age groups and geographic settings.

As the UN's only cosponsored Joint Programme, UNAIDS has spearheaded a coordinated, multisectoral HIV response for nearly 30 years. The 2021 UN Political Declaration on HIV and AIDS, supported by UNAIDS' Global AIDS Strategy 2021-2026, charts a clear path to end AIDS as a public health threat by 2030. Taking this path is a sound political and financial choice that will save lives. We need a fully funded Joint Programme to drive the last mile, deliver SDG 3.3 and sustain progress.
