Ethical issues in the field of Health and health care address multiple topics such as reproductive health, obligations of states in the provision of care and measures to combat infectious diseases. Historically, scientists have been discussing these issues since the beginning of Medicine, and international standards of Health Ethics appeared after the Nuremberg experiments of 1947. The Nuremberg Code contains important principles for health research involving human participants, and with increasing health challenges, the need for clear Ethics in health policies and practices to ensure justice and equality is emerging.
