LONDON - AIDS drugs used to treat HIV can also be used to prevent infection among heterosexual men and women, according to the results of two studies conducted in Africa released on Wednesday.

The findings add to growing evidence that drugs used since the mid-1990s to treat people who are already sick may also hold the key to slowing the spread of the sexually transmitted disease.

The research involving couples in Kenya, Uganda and Botswana found that giving daily AIDS drugs reduced infection rates by at least 62 percent when compared with placebo.

The study was funded by the Bill & Melinda Gates Foundation, whose director of HIV and Tuberculosis, Stefano Bertozzi, said it marked "a significant milestone in the quest to develop new HIV prevention measures".
