VIEW CLE Accreditation by State

Program Overview

Epidemiology is the study of the causes and patterns of diseases in populations. This science is essential to establishing general causation, that is, whether exposure to an agent is capable of causing a health effect. This webinar will provide an overview of epidemiology and explain how an exposure and a health outcome may be associated due to a causal effect or due to other, non-causal reasons. Examples will be given to illustrate how epidemiologists evaluate the weight of scientific evidence to determine whether general causation has been established.
