Epidemiology is the study of how disease is distributed in populations and what factors determine that distribution, work that underlies public health practice from outbreak investigation to prevention policy.
Facts
Founded Year Central QuestionWhat in a population, rather than in any one patient, explains why a disease spreads or a health outcome occurs, and what intervention at the population level would change that outcome? 2 ScopeEpidemiology is the study of the distribution and determinants of health-related states and events in specified populations, and the application of that study to controlling health problems. 2 SignificanceJohn Snow's investigation of the 1854 Broad Street cholera outbreak in London, tracing cases to a single contaminated water pump years before the germ theory of disease was established, is widely regarded as the founding achievement of modern epidemiology. 2 Connections
