HIV drugs can be used to boost protection against HIV as well as treating symptoms after infection, research suggests.
In what is being hailed as a major advance in the battle against AIDS, two studies in Africa have shown that a daily pill containing either one or two anti-HIV drugs can reduce transmission of the virus by as much as three-quarters among heterosexual couples.
The World Health Organization said the studies could have "enormous impact" in preventing HIV transmission.
Roughly 33 million people worldwide have HIV, the virus that causes AIDS, and live in Africa and Asia where medicines to treat the virus must be affordable in order for those who have little funds to buy the drugs.
The findings were revealed in the run-up to an AIDS conference in Rome.
