The Joint United Nations Programme on HIV/AIDS (UNAIDS) is the leading advocate for globalaction on HIV/AIDS. It brings together seven UN agencies in a common effort to fight the epidemic: the United Nations Children’s Fund (UNICEF), the United Nations Development Programme (UNDP), the United Nations Population Fund (UNFPA), the United Nations International Drug Control Programme (UNDCP), the United Nations Educational, Scientific and Cultural Organization (UNESCO), the World Health Organization (WHO) and the World Bank.

UNAIDS both mobilizes the responses to the epidemic of its seven cosponsoring organizations and supplements these efforts with special initiatives. Its purpose is to lead and assist an expansion of the international response to HIV on all fronts: medical, public health, social, economic, cultural, political and human rights. UNAIDS works with a broad range of partners - governmental and NGO, business, scientific and lay - to share knowledge, skills and best practice across boundaries.
