Researchers cast doubt on hypothesis that stigma fuels HIV epidemicOctober 31, 2006The dominant view in the public health community is that the stigma of being HIV positive fuels the HIV epidemic, and yet there is a lack of evidence to support this view, say two researchers in a provocative essay in PLoS Medicine. In a 2002 report, UNAIDS declared that the stigma associated with HIV was one of the "greatest barriers" to preventing new HIV infections and alleviating the impact of the disease. The standard argument for the link between HIV stigma and the global HIV epidemic, say Daniel Reidpath (Brunel University, UK) and Kit Yee Chan (Deakin University, Australia) is that stigma undermines HIV prevention efforts by making a person afraid to engage in safe behavior or seek testing for fear that these acts would themselves raise suspicion in the minds of others about the person's HIV status. Reidpath and Chan say that there is no good evidence to support this argument. "To establish a causal link between HIV stigma and epidemic progression," they say, "requires longitudinal data on rates of infection and levels of HIV stigma. Weaker, but nonetheless potentially persuasive, evidence could also be found in an observed correlation between levels of HIV-related stigma and rates of HIV infection across contexts-such as between countries. Currently, no such evidence is available."
An alternative hypothesis, they say, is that stigma may in fact help to slow the epidemic. "It is plausible," they say, "that a social control mechanism, such as stigma, could reduce opportunities for contact between high- and low-risk groups." "In writing this essay," say the authors, "our aim was neither to diminish the suffering of people living with AIDS in the eyes of the reader nor to advocate for the use of HIV stigma as a mechanism to control the spread of the epidemic. Our objective was to draw attention to the lack of evidence supporting the current dominant view on the relationship between stigma and the global spread of HIV."

Related HIV Epidemic Current Events and HIV Epidemic News Articles Urbanization in Africa at dawn of 20th century marked outbreak of HIV New research indicates that the most pervasive global strain of HIV began spreading among humans between 1884 and 1924, suggesting that growing urbanization in colonial Africa set the stage for the HIV/AIDS pandemic. Climate change threats to HIV rates Social factors, including economic pressures caused by climate change, could lead to an increase in HIV infection rates world-wide, warns a leading researcher from the University of New South Wales (UNSW). U of M researchers develop new online tool in fight against spread of HIV A new Web-based software program is the latest tool University of Minnesota researchers are using to help fight the spread of HIV. A multidisciplinary team of researchers led by Joseph Konstan, a professor in computer science and engineering, and B. R. Simon Rosser, a professor in the School of Public Health, are embarking on a clinical trial this month to test a software program that aims to reduce risk-taking behavior associated with the spread of HIV and other sexually transmitted infections. Different HIV rates among gay men and straight people not fully explained by sexual behavior Differences in sexual behaviours do not fully explain why the US HIV epidemic affects gay men so much more than straight men and women, claims research published ahead of print in the journal Sexually Transmitted Infections. High-risk behaviors could lead to HIV epidemic in Afghanistan In a report that is among the first to describe the prevalence of HIV and Hepatitis B and C viruses in Afghanistan, a researcher from the University of California, San Diego (UCSD) School of Medicine voiced concerns that increasing injection drug use and accompanying high-risk behavior could lead to an HIV epidemic in Afghanistan. Male circumcision for HIV prevention and more Three clinical trials in Africa found that adult male circumcision reduced the risk of men acquiring HIV infection from heterosexual sex by 51-60%. Heavy drinking can hasten the progression of the simian immunodeficiency virus disease Alcohol abuse can impair a person's immune system, leading to infections like pneumonia. Alcohol abuse is also more common among individuals already infected with human immunodeficiency virus (HIV) than among the population as a whole. How HIV 'exhausts' killer T cells American and South African scientists working at the epicenter of the AIDS epidemic in South Africa have discovered how the human immunodeficiency virus (HIV) "exhausts" killer T cells that would otherwise attack the virus. Researchers seek to solve mystery of natural HIV control An international, multi-institutional research consortium is seeking to discover how a few HIV-infected individuals are naturally able to suppress replication of the virus. AIDS research agenda proposed In an Editorial Review published in the current issue of AIDS (2006,20,7, 1-5), HIV researchers from Argentina, Australia, South Africa, and the United States address the challenging question of the impact of major social, ecological, political, economic, biomedical, viral, and other changes on the HIV epidemic and the world's ability to respond.
