Proyecto ContraSIDA por Vida (also known as PCPV and Proyecto) was a non-profit HIV-prevention agency located in the Mission District of San Francisco that provided community-based healthcare for the Latino/a and LGBT communities. It was one of several community-based health organizations that emerged in response to the AIDS crisis. Proyecto ContraSIDA por Vida emerged from a variety of organizations that aimed at reducing the spread of HIV in communities of color. Some of the predecessor organizations of PCPV were the National Task Force on AIDS Prevention (NTFAP), the Gay Latino Alliance (GALA), and Community United in Responding to AIDS/SIDA (CURAS), among others. Some of the leaders who came together to create PCPV included Ricardo Bracho, Diane Felix, Jesse Johnson, Hector León, Reggie Williams, and Martín Ornellas-Quintero.
Three components distinguished PCPV's unique contribution to LGBT organizations and AIDS advocacy efforts: a commitment to multi-gender organizing, sex-positive programming, and principles of harm reduction. Operated from 1993 to 2005, the agency had emerged from the CURAS (Community Responding to AIDS/SIDA) and targeted those under-served by existing HIV-prevention resources, including transgender women, Spanish-speaking immigrants, Latino youth, and neighborhood sex workers.
PCPV was committed to new forms of community building. It promoted health education by addressing differences in age, language, class, immigrant status, and gender. Its dynamic approach to community engagement, education, and outreach was inspired by Paulo Freire, the Centre for Contemporary Cultural Studies at the University of Birmingham, ACT-UP, and El movimiento de liberación gay based in Mexico City.
