Judith D. Auerbach, Sociologist and Independent Science and Policy Consultant
Although it became almost heretical to register any doubt at AIDS 2012 about achieving an end to AIDS in the near future, there were many scientists, practitioners, policy advocates, and community representatives who pointed out some of the challenges. These include the fact that even if new infections decline precipitously in coming years, there will still be millions of people living with HIV for quite some time. The financial and social implications of this will remain high. In the current global economic crisis, the question of who will pay for HIV prevention, treatment, care and support services for over 30 million people is paramount. The U.S. government, through its President's Emergency Plan for AIDS Relief (PEPFAR) and its contribution to the Global Fund for HIV, TB and Malaria, has been the biggest funder of programs throughout the world, but there is no guarantee that its level of support can be maintained.
Moreover, the success of HIV/AIDS programs is dependent on a host of other social factors besides direct funding of them. These include social/structural issues related to such things as the structure and capacity of health systems, equality or inequality in access to services, education and social marketing about HIV prevention and care, appropriate targeting of interventions to particular population groups, and the influence of local culture, religion, and law on stigma or acceptance of people living with or at risk of HIV. There are also psycho-social issues related to the perceptions individuals have about and the meanings they give to HIV prevention and treatment strategies. All research on both biomedical technologies (such as male circumcision, and ARV) and behavioral interventions (such as condom-use and sexual negotiation skills-building programs) concludes that they are only effective if used. "Adherence" - using methods correctly and consistently - is the key to the success or failure of any HIV prevention or treatment modality, and it is fundamentally a function of psycho-social dynamics - comfort, ease, and desire of use - that reside primarily with individuals. What this means is that, even if the new prevention technologies highlighted at AIDS 2012 and among "treatment as prevention" advocates show efficacy in somewhat rarified clinical trials, their effectiveness at a population level will be affected by complex social and behavioral conditions that exist in "the real world."
These realities did receive some attention at AIDS 2012 in the form of sessions devoted to the "social determinants of health". Speakers highlighted the ways in which macro and micro social factors, such as political economy, gender inequality, housing, migration, conflict and violence, human rights laws, organized religion, etc. affect HIV epidemics and responses to them. The causal chains between social forces and individual health outcomes are complex and often non-linear, and they operate through multiple intermediate factors at the institutional and individual levels. As such, it is quite difficult to devise interventions to change social factors and to evaluate their effectiveness on HIV outcomes in the short-term. But, as many scholars and advocates have argued, it is essential to address social/structural factors as both drivers themselves of HIV epidemics and as potential facilitators of the effectiveness of technological advances in HIV prevention and treatment.
What was both fascinating and troubling to observe at AIDS 2012 was that these two conversations - one focused on biomedical technologies (particularly "treatment as prevention") that will help bring about an "AIDS-free generation", and the other focused on the "social determinants of health" that will either facilitate or impede that outcome - took place on parallel tracks. Almost no one brought the two streams together. But this is precisely what must occur if we are to truly "end AIDS". New technological developments will only work if people who need them have unfettered access to them (including payment for them), believe they will help more than harm them, and are able to take them up without fear of discrimination or social marginalization, regardless of their sex, gender, class, age, religion, race/ethnicity, citizenship or immigration status. Getting to this place will require more cross-disciplinary discussions that genuinely value the contributions of social, behavioral, and biomedical sciences equally, and it will require more inter-sectoral discussions seeking ways to translate scientific evidence into social and structural changes that can truly facilitate the end of AIDS.
