Public health is “the science and art of preventing disease, prolonging life and promoting human health through organized efforts and informed choices of society, organizations, public and private, communities and individuals.” Winslow, Charles-Edward Amory (1920). “The Untilled Field of Public Health”. Modern Medicine. 2: 183–191. The broad scope of public health requires the coordination of multiple disciplines such as epidemiology, statistics, medicine, economics, sociology, etc. Modules built on case studies that incorporate data from several of these fields can be found on this page.
