What Is The Epidemiologic Triangle

In 1900, the death rate per 100,000 population for influenza and pneumonia (I & P) was 202.2; it was 22.4 in 2003. How much did the death rate due to I & P decline

Epidemiology defined: The basic science of public health in which the causing factor, population, frequency, and relevant intervention is found in the case of an outbreak.

The epidemilogic triangle describes the relationships and interactions among the infectious agent, the host, and

Originally, epidemiology was a term that was used to describe the spread of infectious disease. Over the course of time, that definition has expanded considerably in order

Friis and Sellers (2004) defined Epidemiology as the science concerned with the distribution and determinants of health and diseases, morbidity, injuries, disability, and mortality in populations. The primary goal of epidemiology is to identify the determinants of

3. Discuss the epidemiologic triangle as it relates to the communicable disease you have selected. Include the host factors, agent factors (presence or absence), and environmental factors. (The textbook describes each element of the epidemiologic triangle).

Epidemiology, What? Is that even an English word? Epidemiology is the study of health and health concerns in a population with an emphasis on establishing cause and effect. Epidemiology looks at how the disease manifests and spreads through out a population that are a risk and come up with effective prevention and treatment.

Epidemiology is the study of distribution and determinants of health-related states or events in specified populations and the application of this study to the control of health problems. The epidemiological triad model holds that infectious diseases result from the interaction of agent, host, and environment (CDC, 2012). Disease transmission occurs when the agent leaves the reservoir or host through a portal of exit, are the conveyed by some mode of transmission and enters through and appropriate portal of entry on infecting a susceptible host (CDC, 2012). This sequence is sometimes called the chain of

A communicable disease chain is the mechanism by which an infective agent or pathogen is transmitted. The chain requires an infective agent, a source of infection, a mode of transmission and a host. An example of an infective agent could be bacteria, a virus, fungus, protozoan or helminth. The source of infective agents can be transmission from host to host, an infected human or animal, insects, soil or livestock. The mode of transmission is how the infective agent is carried from host to host. Transmission can be by air, ingestion or physical contact. To complete a life cycle or to replicate, the infective agent requires a host.

The epidemiology triangle has three sides. The sides consist of the host, the agent and the environment. 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). The agent interacts with the host and the environment to cause the disease. The environment is all the outside conditions that make the host susceptible to the agent. One condition of the environment could be the health of the host.

Leavell and Clark model wanted to explain how the relationship between an agent, host, and environment could affect an individual’s’ health. Agent-Host-Environment model, according to Leavell and Clark, is beneficial for investigative causes of disease in an individual. The model attempts to explain how the interconnection of three separate elements correlates to affect an individual health status. The agent-host-environmental model suggests, how certain factors must be present or absent for an illness to occur; and as a result of such external factor a living organism is capable of being adversely infected or affected by outside influences (Leavell and Clark, 1965).

Epidemiology is what advises people of new world epidemics and new health standards worldwide. Epidemiologist are well known for their ideal way to handle and control epidemics of the everyday modern world by conducting research and going through various experiments. Epidemiology was first well known in the mid-1800´s (1854) but is know to have existed for about 2,500 years

This paper defines and explains the six core functions of epidemiology: Public health surveillance, field investigation, analytic studies, evaluations, linkages, and policy development. The core functions of epidemiology lay down a foundation on which epidemiologists can begin to work from. This paper will look at the benefits of incorporating all six of these functions into a working plan when health officials, medical personnel, first responders, etc., encounter a disease or illness that needs to be identified, treated and contained.

Epidemiology is a medical science discipline that arranges the structure for studying the distribution and determinants of health, communicable disease, and circumstances related to health status. The epidemiology research help to understand in what means a person catch diseases, the changes, and how the disease affect the population. The nurses that work with these communities to help identify the onset of communicable diseases determine new victims, the patterns it spread, the causes or preventive methods are known as community or public health nursing (Maurer, Smith, 2013). The purpose of this paper is to explain on the concepts of a communicable disease “Chickenpox” with its own unique epidemiology and nursing research to this
