Research Highlights from the International AIDS Conference

Researchers and scientists presented many exciting new findings at the 2011 International AIDS Conference, held in Rome in July and organized by the International AIDS Society (IAS). The Center for Global Health Policy was there with live coverage on Science Speaks, the Center’s blog.

Highlights include:

  • WHO moves forward but does not release new guidance for HIV-discordant couples: A premeeting session originally expected to feature long-anticipated World Health Organization (WHO) guidance on HIV counseling, testing, and access to antiretroviral therapy for sero-discordant couples—where one partner is HIV-infected and the other is not—instead highlighted the work in progress in clinical trials confirming the efficacy of HIV treatment and pre-exposure prophylaxis (PrEP) using antiretrovirals.

  • IAS 2011: Where we go from here: In an exclusive video interview with Science Speaks, the director of the National Institute of Allergy and Infectious Diseases, Anthony Fauci, MD, FIDSA, spoke about treatment as prevention, PrEP, and the way forward.

  • Male circumcision curbs spread of HIV over time, risky behavior does not increase: Three years after the voluntary medical male circumcision campaign began in the Orange Farm Township in South Africa, the first real-world results show a marked reduction of HIV acquisition among circumcised adult men, a drop in HIV incidence of 76 percent among men in the community, and HIV prevalence among circumcised men that is 55 percent lower.

  • PrEP works for heterosexual couples too: Preliminary results from two large studies have now shown that a daily antiretroviral tablet taken by people who do not have HIV reduces their risk of contracting the virus by up to 73 percent.
