Introductory editorial: The analysis of a natural experiment in HIV control

Abstract

The issue editors outline what they consider to be the reasons behind the continuing success of HIV control among men who have sex with men in New South Wales (NSW). They suggest that continuing, high-level and coordinated investment in HIV prevention in NSW compared with a disinvestment in other Australian jurisdictions has resulted in sustained reductions in HIV risk behaviour in NSW at a cost of $A31250 per HIV case prevented. © CSIRO 2008.
