Abstract
AIDS 2008 firmly established stigma and discrimination as fundamental priorities in the push for universal access to HIV prevention, treatment, care and support. Conference sessions and discussions reinforced the tangible negative effects of stigma on national legislation and policies. A strong theme throughout the conference was the need to replace prevention interventions that focus exclusively on individual behaviour change or biomedical prevention interventions with "combination prevention" approaches that address both individual and structural factors that increase vulnerability to HIV infection.Several high-level sessions addressed various aspects of the debate over "vertical" (disease-specific) versus "horizontal" (health systems) funding. The majority of evidence presented at the conference suggests that HIV investments strengthen health systems through the establishment of clinical and laboratory infrastructure, strengthened supply and procurement systems, improvements in health care worker training, and increased community engagement.Human rights were a focal point at the conference; several presentations emphasized the importance of securing human rights to achieve universal access goals, including workplace discrimination, travel restrictions, gender inequality, and the criminalization of homosexuality, drug use, sex work, and HIV transmission and/or exposure.
