From Latin facere,
to do, to make. Literally a maker, a person who performs a designated function in an organization. In common public health and epidemiological usage, the word describes a specific agent, event, or process that brings about a change in health status or initiates a specific outcome. Sometimes the word is used loosely as a synonym for a causal agent when the correct term is usually determinant or risk factor. See also protective factor.
