Abstract

At its core, public health introduces tensions between individuals' autonomy and the need to account for the perspectives and needs of communities and populations. It further raises social justice issues, including fair allocation of limited resources. This article examines and elaborates on these tensions and their resolutions using specific public health examples. Experiences in the 1980s and 1990s with HIV/AIDS provide a particularly rich collection of issues that brought ethical issues in public health to the public's attention, and in so doing challenged previously held assumptions about the appropriate consideration of individual rights in the context of population health objectives. Lastly, the article examines some of the ethical challenges arising in public health applications of recent science and technology advances, specifically the emerging area of public health genomics and the large scale collection and analysis of health information.
