Informed consent and public health.

During the past 25 years, medical ethics has concentrated largely on clinical medicine and the treatment of individual patients. This focus permits a view of medical provision as a (quasi-) consumer good, whose distribution can be or should be contingent on individual choice. The approach cannot be extended to public health provision. Public health provision, including measures for limiting the spread of infectious diseases, is a public good and can be provided for some only if provided for many. The provision or non-provision of public goods cannot be contingent on individual informed consent, so must be in some respects compulsory. An adequate ethics of public health needs to set aside debates about informed consent and to consider the permissible limits of just compulsion for various types of public good. It will therefore gain more from engaging with work in political philosophy than with individualistic work in ethics.
