Anti-AIDS pill makes cash sense for some gays

(WASHINGTON-AFP) - Gay men who have five or more sex partners per year are part of a high-risk group that could benefit from a daily pill to ward off HIV, said a cost-benefit analysis by US researchers on Monday.

The study by experts at Stanford University, published in the Annals of Internal Medicine, looked at the costs involved with prescribing a $26 a day pill to men who have sex with men.

The pill, Truvada (tenofovir-emtricitabine), was shown in a landmark 2010 trial published in the New England Journal of Medicine to prevent HIV infections in as many as 73 percent of gay men who took it regularly.

Gay men account for the more than half of the 56,000 new cases yearly of human immunodeficiency virus in the United States, according to the Centers for Disease Control and Prevention.
