AIDS and ethics: an analytic framework.

The acquired immunodeficiency syndrome (AIDS) pandemic has raised difficult ethical issues in public policy formulation and in the care of patients infected with the human immunodeficiency virus (HIV). Many issues relate to measures proposed for the protection of the public from HIV infection. This article presents an analytic framework from which these measures can be rationally evaluated. Specific measures are assessed on the basis of their likelihood of success, in relation to their justification for infringement on individual rights, and with reference to other less intrusive measures that could accomplish the same objective. Case histories are discussed which raise ethical dilemmas in the care of HIV infected and high-risk patients. The application of this framework could assist physicians in analysing public health policy and making judgements in individual clinical situations.
