This study will compare two models of rural HIV testing and care services in two districts of Maharashtra, India. The "Control" model is the Indian government's current strategy of "partially decentralized" rural-based HIV testing services at a secondary-level Community Health Center clinic, which serves a village group population of 30,000. HIV care including antiretroviral therapy is provided a the rural district headquarters in the district urban center. The "Intervention" model is a novel model of "fully decentralized" rural-based HIV testing which will be offered at the Community Health Center, two Primary Health Centers, and eight village-level sub-center clinics, and HIV care offered at a rural-based clinic.
