UNAIDS, the Joint United Nations Programme on HIV/AIDS, is an innovative joint venture of the United Nations family, bringing together the efforts and resources of ten UN system organizations in the AIDS response to help the world prevent new HIV infections, care for people living with HIV, and mitigate the impact of the epidemic. With its headquarters in Geneva, Switzerland, the UNAIDS Secretariat works on the ground in more than 80 countries worldwide. Coherent action on AIDS by the UN system is coordinated in countries through the UN theme groups, and the joint programmes on AIDS. Cosponsors include UNHCR, UNICEF, WFP,UNDP, UNFPA, UNODC, ILO, UNESCO, WHO and the World Bank. UNAIDS helps mount and support an expanded response to AIDS — one that engages the efforts of many sectors and partners from government and civil society.
