A major purpose of this article is to provide ethical aspects in public health. This is not intended to establish theoretical and philosopical argument for issues of health care ethics, but intended to describe the necessity of ethics education in public health. The increase in medical science to sustain life and the failure to provide corresponding ethical guideline in public health have created new ethical problems. All members in public health trainning programs should not only have an interest in health care ethics, but also have an ability to reach decisions in ethical problems related to community. The goal of ethics education in public health is not to improve the moral character of health care providers but rather to provide them with the conceptual abilities and decision-making skills they will need to deal successfully with ethical issues in public health research and practice. Obviously. the ultimate goal is to increase awareness of human values in health care.
