Early Treatment Could Avert Millions of AIDS Cases, Study Shows

Millions of HIV infections could be averted by treating patients earlier than current guidelines recommend, after a study showed giving pills to patients as soon as they’re diagnosed can prevent them infecting others.

In a trial among 1,763 couples where only one partner was infected, those who started treatment immediately were 96 percent less likely to transmit the AIDS-causing virus to their uninfected partner than those who started therapy later. The study, which was due to end in 2015, was terminated early because the effect was so clear, U.S. National Institute of Allergy and Infectious Diseases said in a statement yesterday.
