Epidemiology is the study of the distribution (who, when, where) and determinants (causes, risk factors) of health-related states in specified populations. It operates through three core parameters: (1) population-level observation rather than individual diagnosis, (2) quantitative measurement of frequency and association, and (3) causal inference from observed patterns. Epidemiology persists through institutionalized practices: surveillance systems, study designs (cohort, case-control, cross-sectional), statistical methods, and peer-reviewed publication — sustained by public health organizations, academic departments, and WHO/CDC networks.
