This briefing paper takes an in-depth look at the standards developed by six UN "treaty monitoring bodies," or committees, in the area of HIV/AIDS and other STIs. Following a brief overview of the origin and work of the committees, this paper reviews standards each body has adopted as it has monitored governments' compliance with their duties under international human rights law, including references to gender. In repeated statements, these bodies have made clear that, in the context of HIV/AIDS and other STIs, governments are bound by international standards to ensure prevention, care, and protection from discrimination.
