ABSTRACT
In New York, Paris, San Francisco, Amsterdam, London and several other large urban centres throughout developed countries, the percentage of gay men who become HIV positive each year has fallen to a low point of less than 2 per cent. One reason for this decline in the incidence of HIV infection has been a dramatic change in behaviour from unsafe to safer sex.1 While an ongoing infection rate of between one and two in a hundred still borders on epidemic proportions, and while there is some evidence of a slight upturn in the number of men becoming infected by HIV, the overall picture is one of unprecedented change in gay men’s sexual behaviour.
