Origin John Snows 1854 mapping of a London cholera outbreak to a contaminated Broad Street water pump is widely treated as the founding demonstration of epidemiological method, though population-level disease observation predates it.

Epidemiology is the study of how disease and health outcomes are distributed across populations and the factors that influence that distribution. John Snows 1854 investigation of a cholera outbreak around a Broad Street water pump in London, tracing the disease to contaminated water rather than bad air, is widely cited as a founding demonstration of its method. This atlas records what the historical record supports and is not medical advice.

  • Lead section, sentences 1-2
    Epidemiology is the study and analysis of the distribution (who, when, and where), patterns and determinants of health and disease conditions in a defined population, and application of this knowledge to prevent diseases. It is a cornerstone of public health, and shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare.
