The Epidemiologic Triangle is a model used to show the balance of health and disease as a united state of three factors: agent, host and environment. The agent or microbe is what causes the disease, the host is an organism harboring the disease or a population at risk for developing the disease, and the environment is the contributing external factors that cause or allow disease transmission This model helps us to understand how the agent, host and environment coexist with each other in a state of equilibrium or balance and then represents the spread of disease or injury when there is a shift to that equilibrium or balance

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.
6, 2013) 10. Epidemiology is the focus on addressing the importance of social characteristics (including gender, race, and social class), lifestyle, and the social and physical environment (including such things as employment status, stress, exposure to toxic substance, and participation in social networks) on disease and illness. ( ]Page 35 in the textbook) 11. An epidemiologist is a person who studies patterns of diseases or health risks in population groups, societies, and cultures.
The study of disease transmission is the review and examination of the examples, causes, and impacts of wellbeing and illness conditions in characterized populaces. It is the foundation of general wellbeing, and shapes strategy choices and confirmation based practice by recognizing hazard variables for ailment and focuses for preventive human services. ("Epidemiology - Wikipedia," n.d.)
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).
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
The epidemilogic triangle describes the relationships and interactions among the infectious agent, the host, and
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.
(DM2). It will focus only on DM2, as type 1 diabetes (DM1) is an autoimmune disorder. Canada
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
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
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.
\item SI-models, these are the simplest models in which the transmission of the disease occurs through the interaction of two states, namely susceptible (S) and infectious (I). The assumption is that the route of infection is through direct contact between susceptible individuals and infected individuals and the infective remain infectious for the rest of the disease lifetime. These types of models are mostly applicable to the study of disease that does not confer to immunity. \item SIP models are the simplest models in which the transmission of the disease occurs between the susceptible and free-living pathogens in the environment. The force of infection is assumed to be dependent on the population of free-living pathogens. \item SIS-model, these models are similar to the SI-models, but the assumption is that infectious confer immunity to recover from the disease and become susceptible again.
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
