In this post in the Human Rights and HIV/AIDS “Now More Than Ever” blog, Michel Kazatchkine, the former executive director of the Global Fund to Fight AIDS, Tuberculosis and Malaria and newly appointed special envoy to U.N. Secretary-General Ban Ki-moon for HIV/AIDS in Eastern Europe and Central Asia, examines why human rights are “so central to the AIDS response.” He writes, “An urgent mobilization is needed to respond to the epidemic in Eastern Europe and Central Asia, including much greater attention to, and involvement of marginalized and criminalized populations, particularly people who use drugs, sex workers, and gay men and other men who have sex with men,” adding, “As Special Envoy, I will continue to speak out loudly and clearly about the need to devote much greater attention to human rights. And I pledge to listen to the voices of those who too often are excluded” (7/26).
