Resource-limited countries with high rates of infection face the biggest challenges in addressing the HIV/AIDS pandemic, as government and non-governmental infrastructures are often undeveloped and slow to shift their focus away from nation-building and other perceived priorities in order to scale up their response to HIV/AIDS. This article examines the role of trained volunteers who provide Home-Based Family Care in the high HIV-prevalence, resource-limited country of Namibia in Southern Africa. While each volunteer alone can make only a small difference, an organization that effectively uses many volunteers can make a large impact. Special focus is given to the experi-ence-and potential-of churches to recruit, train, and help sustain volunteers to provide AIDS care and support. The case example of Catholic AIDS Action in Namibia-that country's largest non-governmental organization dedicated to HIV-related prevention and care-is used to illustrate key points. The article concludes with “lessons learned” that can be applied to other non-governmental and faith-based providers who seek to recruit and involve volunteers in the provision of direct-care services.
