The second component is the host which is classified as the human or animal that the disease inhabits. The third component is the environment which the surroundings that are external to the hosts body that allow for the transmission of the disease. Models of disease and injury facilitate our understanding of their etiology or causes. Etiology is the science of causation. The Epidemiological Triad The best known, but most dated model of communicable disease is the Epidemiologic Triad (Figure 1). This model comprises a susceptible host (the person at risk for the disease ), a disease agent ( the proximate cause ), and an environmental context for the interaction between host and agent. The first is the agent which is the causes the disease.

The host is the person who is affected by the disease. The agent is the organism causing the disease. “In the case of type II diabetes, the agent could be the absence of a substance.” (McMurray, 2006).

This means it is not only the causative agent that is responsible for disease but there are another factors also, related to man and environment … Public health surveillance and epidemiologic research can inform environmental microbiology research and practice.
