The Center for Global Health Policy’s “Science Speaks” reports on a symposium that took place at last week’s Conference on Retroviruses and Opportunistic Infections (CROI), which “showed how existing information, including from Demographic and Health Surveys, combined with sentinel surveillance from more limited populations, can gather critical information on the path of epidemics and be used to inform the policies and practice of HIV responses.” The blog also summarizes recent articles on how homophobia is affecting efforts against HIV/AIDS (Barton, 3/12).
