Epidemiological Triangle Agent
Epidemiological triangle agent The epidemiologic triad has been applied to the study of injury by scientists at the centers for disease control and prevention cdc figure 3.
Epidemiological triangle agent. The triad is a methodology that characterizes infectious diseases because it identifies the interaction between the environmental agent virus and host. Agent the agent is the microorganism that actually causes the disease in question. A number of models of disease causation have been proposed. A traditional model of infectious disease causation known as the epidemiologic triad is depicted in figure 2.
The triad consists of an external agent a susceptible host and an environment that brings the host and agent together. Humans are the host for influenza as they are the animal capable of full blown infection. The triad consists of an external agent a susceptible host and an environment that brings the host and agent together. An agent could be some form of bacteria virus fungus or host.
Agent host and environment. According to maurer and smith 2009 the epidemiological triangle comprises four parts. What is the epidemiological triangle. The epidemiologic triangle is a model that scientists have developed for studying health problems.
For injury the agent is any one of the five forms of physical energy. Case series edit case series may refer to the qualitative study of the experience of a single patient or small group of patients with a similar diagnosis or to a statistical factor with the potential to produce illness with periods when they are unexposed. The epidemiological triad is a model that allows to evaluate the causality and the interactions of the agents that propagate an infectious disease. The triad consists of an external agent a host and an environment in which host and agent are brought together causing the disease to occur in the host.
Host environment agent and time. The epidemiologic triad a number of models of disease causation have been proposed. The term epidemiologic triad is used to describe the intersection of host agent and environment in analyzing an outbreak. Among the simplest of these is the epidemiologic triad or triangle the traditional model for infectious disease.
