Such occupations include veterinarians, animal handlers, abattoir workers, and laboratorians. The epidemiological Triangle model includes three key elements: the agent, host, and environment. The National Institute for Health has broken down how the triangle can be applied to COVID-19.8. Two ways of depicting this model are shown in Figure 1.16. Agents of infectious diseases include bacteria, viruses, parasites, fungi, and molds. The other model shows agent and host as variables that are dependent on each other and on the environment. A number of models of disease causation have been proposed. Anthrax can also be spread as a bioterrorist agent. To help identify the key risk factors, Sam begins to examine three categories of risk central to epidemiology. _____ Skin contact with a strong acid /Burn. What is a chemical feedstock? A disease may have more than one sufficient cause, with each sufficient cause being composed of several component causes that may or may not overlap.

The epidemiologic triangle, depicts the relationship among three key factors in the occurrence of disease or injury: agent, environment, Healthcare staff should follow best practices and procedures to help prevent infections from spreading in your facility. Since different diseases require different balances and interactions between these three factors, its critical to fully assess each component in order to develop effective control and prevention measures. For example, even exposure to a highly infectious agent such as measles virus does not invariably result in measles disease. WebWhat are the three components of the epidemiological triangle?
