This week’s issue of the Lancet “has an HIV theme ahead of the International AIDS Society meeting in Washington, D.C., … on July 22-27,” a Lancet editorial states, noting, “The issue of antiretrovirals for prevention, specifically pre-exposure prophylaxis, is presently under intense debate.” According to the editorial, “Two articles present further efforts to make treatment better and improve patients’ adherence,” and “[a] third article shows the benefits of antiretrovirals when given to either mothers or infants to prevent HIV transmission via breastfeeding” (6/29).
