Imagine a single pill that could stop the transmission of HIV among women. Researchers at UT Southwestern Medical Center in Dallas think that they might be close.
Researchers there say that they've found that some drugs used to treat patients with HIV might also prevent the vaginal transmission of the virus that causes aids- if a woman takes it before and after exposure.
Dr. J. Victor Garcia of UT Southwestern Medical Center said, "These would have the most dramatic effect in places where the incidents of HIV is high and therefore the risk of transmission is also higher. This could potentially prevent 3 million transmission events in a period of 10 years."
Dr. Garcia says the pill has worked in what he calls "humanized" mice. The CDC is now testing the drugs in humans.
