Scientists have an exciting breakthrough in the fight against AIDS. A pill already used to treat HIV infection turns out to be a powerful weapon in protecting healthy gay men from catching the virus, a global study found.
Daily doses of Truvada cut the risk of infection by 44 percent when given with condoms, counseling and other prevention services. Men who took their pills most faithfully had even more protection, up to 73 percent.
Researchers had feared the pills might give a false sense of security and make men less likely to use condoms or to limit their partners, but the opposite happened — risky sex declined.
The results are "a major advance" that can help curb the epidemic in gay men, said Dr. Kevin Fenton, AIDS prevention chief at the U.S. Centers for Disease Control and Prevention. But he warned they may not apply to people exposed to HIV through male-female sex, drug use or other ways. Studies in those groups are under way now.

I really want to know how this works. The article says it's a major advance for gay/bisexual men, but would not apply to M-F couples and needle users. What exactly is this pill doing?
