They help us understand more about potential risk factors for diseases and prevention activities that we might want to look at in more detailed studies. They also help us assess the health status of a population and set health goals.

What three factors are key to understanding communicable disease causation?

Causation. A number of models of disease causation have been proposed. Among the simplest of these is the epidemiologic triad or triangle, the traditional model for infectious disease. The triad consists of an external agent, a susceptible host, and an environment that brings the host and agent together.
