PSI is a registered Indian society in operation since 1988. PSI harnesses the vitality of the private sector to address the health problems of low-income and vulnerable populations. PSI, with programs in safe water, diarrheal disease, nutrition, family planning and HIV/AIDS, uses social marketing to achieve positive behaviour change through the promotion of ideas, products and services supportive of better health.
PSI is currently implementing a multiyear HIV prevention program as part of the Avahan: India AIDS Initiative, funded by the Bill and Melinda Gates Foundation. The project is working to reduce HIV incidence by treating and preventing Sexually Transmitted Infections (STIs) in male clients of commercial sex workers in 100 high priority towns in Andhra Pradesh, Karnataka, Maharashtra, and Tamil Nadu.
