Anthony S. Fauci’s May 29 Sunday Opinion commentary, “30 years of AIDS,” related the history of this scourge: its identification and diagnosis, its virulence and the 30-year struggle to master it (in which he has been so centrally involved). But it’s disappointing that he focused almost exclusively on treatment of those afflicted rather than, with the exception of the search for a vaccine, on prevention.

Dr. Fauci noted that treatment can reduce the transmission of the virus to others, but he did not discuss the armory of prevention, including education, behavior change, condom use, male circumcision and blocking maternal/infant transmission. Surely, given the high cost of treating infected individuals, there is a strong argument that limited resources, as a priority matter,  should be allocated to preventing the spread of the disease. Prevention campaigns have proved effective in many countries.
