In almost 20 years of tackling the AIDS epidemic, one theme has consistently emerged: the solution to stopping the spread of the AIDS virus, HIV, rests with individual behaviour. The critical question is: how can people be influenced to change risk behaviours related to sexual activity and drug use? This volume brings together some of the most respected researchers in the area of reducing the transmission of HIV. Their work represents the state-of-the-art research on safer sex and drug use. The issues discussed include: adolescents at risk from AIDS; denial, motivation and behaviour; and special populations.
