Reducing social vulnerability to HIV/AIDS: models of care and their impact in resource-poor settings.

There has been an increasing understanding of the social, economic, cultural and political factors that have shaped the HIV/AIDS epidemic. It has been widely recognized that in order to have effective prevention programmes for HIV/AIDS, the broader determinants of health must be addressed. Concurrently, a deeper understanding of personal and societal vulnerability to HIV/AIDS has emerged. Some prevention efforts have expanded their focus, addressing not only individual risk factors and behaviour, but also social justice and including community mobilization activities to address the wider context of the disease. However, the transition to an expanded approach to mitigating the effects of the HIV/AIDS epidemic has not been complete. There is little evidence that care and support strategies have systematically tried to address these concepts. While the role care plays in prevention is considered vital, viewing models of care in terms of their impact on the social vulnerability of certain groups to HIV/AIDS has been largely neglected. Yet appropriate care programmes that help reduce vulnerability will arguably also make the greatest contribution for prevention. Drawing on examples of the role social vulnerability has played in prevention efforts, this paper evaluates the impact of HIV/AIDS care models on socially vulnerable groups, such as women and children.
