Efforts to prevent the spread of HIV have, to an overwhelming degree, addressed themselves to the HIV-negative rather than to the positive population.
But it makes sense to direct more preventive work towards positive individuals, for 3 reasons.
First, because changes in the behaviour of positive people have a disproportionately greater effect on the spread of the epidemic-so positivetargeted interventions are potentially more cost-effective, and in many cases enormously so.
Second, positive individuals already show a degree of preventive altruism that generally outweighs the self-protective efforts of those who are negative.
And third, there is reason to believe that this preventive altruism can be strengthened by appropriate interventions.
Some of the practical implications of a shift to greater positive targeting, involving both novel interventions and modified familiar ones, can be sketched out.
