An intensive campaign to combat HIV/Aids with costly antiretroviral drugs in rural South Africa has increased life expectancy by more than 11 years and significantly reduced the risk of infection for healthy individuals, according to new research.
The study, published in the journal Science, comes as wealthy Western nations debate how best to stretch limited Aids funding at a time of economic stress.
With an annual price tag of US$500 to US$900 per patient, antiretroviral therapy programmes have stirred debate.

Cheaper remedies, such as condom distribution, male circumcision and behaviour modification, deserve more attention and funding, they say.
The new economic analysis of a US$10.8 million campaign in KwaZulu-Natal province found that the drug scale-up had been highly cost-effective.
