Two studies conducted in Africa showed for the first time that AIDS drugs designed to treat HIV can also be used to reduce dramatically the risk of infection among heterosexual couples.
The findings add to growing evidence that the type of medicines prescribed since the mid-1990s to treat people who are already sick may also hold the key to slowing or even halting the spread of the sexually transmitted disease.
In a press statement, World Health Organisation (WHO), director-general, Margaret Chan, states that, "Effective new HIV prevention tools are urgently needed and these studies could have enormous impact in preventing heterosexual transmission." Chan says that WHO will now work with countries to use the new findings to implement better protection strategies.
