UNAIDS is an innovative joint venture of the United Nations, bringing together the efforts and resources of the UNAIDS secretariat and ten United Nations organizations to respond to AIDS. The secretariat’s headquarters is in Geneva, Switzerland with staff on the ground in more than 80 countries. Coherent action on AIDS by the United Nations system is coordinated in countries through theme groups and joint programmes on AIDS. UNAIDS cosponsors are: the Office of the United Nations High Commissioner for Refugees (UNHCR); the United Nations Children’s Fund (UNICEF); the World Food Programme (WFP); the United Nations Development Programme (UNDP); the United Nations Population Fund (UNFPA); the United Nations Office on Drugs and Crime (UNODC); the International Labour Organization (ILO); the United Nations Educational, Scientific and Cultural Organization (UNESCO); the World Health Organization (WHO); and the World Bank.UNAIDS seeks to build and support an expanded AIDS response that engages the efforts of many sectors and partners from government, civil society and the private sector. Its five focus areas include: mobilizing leadership and advocacy for effective action on the epidemic; providing strategic information and policies to guide efforts in the AIDS response worldwide; tracking, monitoring and evaluation of the epidemic and the response to it as the world’s leading resource for AIDS-related data and analysis; engaging civil society and developing partnerships; and mobilizing financial, human and technical resources.
