The FDA has approved a pill that can help those having sex with HIV + partners avoid being infected. From the SF Chronicle story:
The U.S. Food and Drug Administration on Monday approved the marketing of the first drug shown to curb the transmission of the HIV virus, a development heralded by AIDS advocates and physicians as a turning point in the battle against the decades-long epidemic.
Truvada, made by Gilead Sciences in Foster City, was approved in 2004 to treat people already infected with HIV, but studies have shown the drug is also effective at reducing the risk of contracting the virus. “It’s a huge milestone that could change the course of the epidemic,” said Dr. Robert Grant, a UCSF professor and a researcher with the Gladstone Institute for Virology and Immunology who led one of the two studies on which the FDA approval was based. “The main challenge is for everyone to start thinking of HIV as a problem that can be prevented,” he said.
