Epidemiology is the study of the distribution and determinants of disease in a population. Public health epidemiologists monitor the health and illness of a population, investigate the factors that affect the community's health, and recommend interventions to reduce the risk of disease. Epidemiology is practiced in health departments daily and involves principles of surveillance, investigation, laboratory testing, data management, and communication.

Epidemiological surveillance is the collection, analysis, and dissemination of health data for the planning, implementation, and evaluation of health programs. The Epidemiology Department at Richmond City Health District collects information in conjunction with the Virginia Department of Health's Division of Surveillance and Investigation (DSI) in order to determine disease impact, assess trends in disease occurrence, characterize affected populations, prioritize control efforts, and evaluates prevention strategies in Richmond City.
