Epidemiologists use a tool to help understand infectious disease known as the epidemiologic triangle. Knowledge Management for Clinical Applications This question is related to Caritas Jockey Club Lok Yan School. The last component in the Epidemiologic Triangle is the environment. As the CDC explains, a variety of factors intrinsic to the host, sometimes called risk factors, can influence an individuals exposure, susceptibility, or response to a causative agent.2,3, Completing the triangle used by epidemiology to model the study of disease and health issues are the extrinsic factors that affect the agent and provide opportunity for the host to be exposed.
