The International AIDS Society (IAS) Conference on HIV Science (IAS 2017) in Paris last week brought together over 6,000 scientists, clinicians, public health practitioners and officials to review the state of the science intended to control and eventually end the HIV/AIDS epidemic. The central thrust of the global effort to control the epidemic is achieving the 90-90-90 targets set by the Joint United Nations Programme on HIV/AIDS (UNAIDS). These targets state that, by 2020, 90% of those living with HIV know their status, 90% of known HIV-positive individuals receive sustained antiretroviral therapy (ART), and 90% of individuals on ART have durable viral suppression. We know that HIV-infected persons with viral suppression, while not cured, do not transmit HIV infection – hence the focus on treatment, which is prevention.
While some countries have made encouraging progress, we are far short of the global 90-90-90 targets, and worse, there were 1.8 million new HIV infections in 2016. We need science to inform the way forward to reach the targets. In this post, I will report on some of the conference presentations around two major themes: 1) generating and applying evidence to optimize the use of current tools, and 2) developing new and improved methods for HIV prevention, care and treatment.
