Predicting the public health impact of anti-retrovirals: preventing HIV in developing countries

The authors of this scientific article use a mathematical model to warn that while the widespread use of antiretrovirals in developing countries could be an effective tool for prevention of HIV infection - as well as treatment - the benefits could be masked by an increase in risky behaviour that promotes the spread of the virus.

They argue that antiretrovirals should be viewed as a non-conventional prevention tool since the drugs have both preventive and therapeutic effects and are given to infected, rather than uninfected, individuals.
