AIDS, a social dilemma: detection of seropositives

At present, we can observe an evolution in ideas about the detection of HIV seropositivity through a qualitative analysis of specialised literature on the ethical aspects of AIDS. In the case of this disease, systematic screening of the population does not correspond to epidemiological criteria: it is wasteful, troublesome and costly. Whether it is voluntary, and therefore biased, or compulsory, and therefore controversial, systematic screening seems an unlikely option. This situation has prompted many versions of target-group screening, which correspond to two options: systematic screening of known risk-groups, discriminatory, confidential and anonymous; target-group screening linked to particular circumstances: recognised as necessary by blood-donors and well-accepted by pregnant mothers. This method can be institutionalised and applied in the armed forces and in prisons,.... Lastly, we consider measures taken by different countries and organisations.
