Public health ethics in the future will be distinguished from public health ethics in the past by this new subfield being labeled as such, acknowledged, and called upon for service. Ethical dilemmas have been present throughout the history of public health. The question of whether to force Henning Jacobson to be immunized in 1905 in accordance with the 1902 Massachusetts smallpox vaccination law was one of ethics as well as law. How Thomas Parran, Surgeon General in 1936, chose to respond (...) to a raging syphilis epidemic in the United States in the early part of the 2W century raised considerable moral debate in determining the appropriate public health response for a government? More recently, questions have arisen concerning the appropriate reach of government in controlling HIV banning smoking, or promoting healthy lifestyles. Debates over government infringement, morality, and justice recur throughout the history of public health. (shrink)
