From social silence to social science: same-sex sexuality, HIV & AIDS and gender in South Africa presents a unique and innovative effort to examine what we know about homosexual transmission of HIV and AIDS in South Africa. It reverses the trend whereby categories of same sex sexual practice are almost always excluded from research of HIV and AIDS, as well as from care and intervention programmes. The varied contributors (academics, activists and programme planners) draw attention to the risk behaviours and treatment needs of people who engage in homosexual sex, and explain why same-sex sexuality has to be seen as key within South African efforts to study, test and prevent HIV infection. Relevant to scholarly debates about HIV and AIDS, it is also essential reading for anyone involved in research, policymaking, advocacy and community development.
