Identifying the source of an outbreak: By analyzing the shape and pattern of the curve, epidemiologists can infer whether an outbreak is from a common source, point source, or propagated source. Determining the mode of transmission: The curve helps distinguish between different modes of transmission (e.g., person-to-person, vector-borne). Evaluating the effectiveness of interventions: By observing changes in the curve after implementing public health measures, one can assess their impact.
