UNAIDS addresses the global AIDS response by bringing together in a concerted manner the efforts and resources of the following UN System Organizations:
UNHCR, UNFPA, WHO, UNICEF, UNESCO, WFP, UNDP, UNODC, ILO, and The World Bank.

Considering that the communities of faiths play a significant role in influencing 
people´s behavior and attitudes, and in providing health care and support for 
HIV/AIDS infected people, UNAIDS prioritizes work at the global level with 
large networks of FBOs and religious leaders, such as: African Network of 
Religious Leaders living with or personally affected by AIDS, Caritas 
International, Ecumenical Advocacy Alliance, Christian Aid, Tear Fund, Islamic 
Medical Association of Uganda, Positive Muslims, Islamic Relief, World 
Conference on Religion and Peace, Sangha Metta Project, and Art of Living 
Foundation.
