Setting and organization of care for persons living with HIV/AIDS.

Treating the world's 40.3 million persons currently infected with HIV/AIDS is an international responsibility that involves unprecedented organizational challenges. Key issues include whether care should be concentrated or decentralized, what type and mix of health workers are needed, and which interventions and mix of programs are best. High volume centres, case management and multi-disciplinary care have been shown to be effective for some chronic illnesses. Application of these findings to HIV/AIDS is less well understood.
