They are: The agent The host The environment WebOther portals of entry include the skin (hookworm), mucous membranes (syphilis), and blood (hepatitis B, human immunodeficiency virus). Epidemiology is the study of the occurrence and distribution of health-related states or events in specified populations, including the study of the determinants influencing such states, and the application of this knowledge to control the health problem. Therefore, it isnt an adequate model to use for diseases such as cardiovascular disease, cancer, and other diseases that appear to have multiple contributing causes.3, The host is the organism which is exposed to and harbors a disease. Kill germs by disinfecting high-touch areas regularly. Two ways of depicting this model are shown in Figure 1.16. The environment also includes social norms that affect the spread of disease (i.e. WebIn a written paper of 1,200-1,500 words, apply the concepts of epidemiology and nursing research to a communicable disease. 3.The test is difficult to perform. Discuss the epidemiologic triangle as it relates to the communicable disease you have selected. Left-sided vocal fold paralysis requires consideration of lesion from the skull base down to the aortic triangle due to the course of the left RLN. For example, the temperature in a given location might affect an agents ability to thrive, as might the quality of drinking water or the accessibility of adequate medical facilities. An individual factor that contributes to cause disease is shown as a piece of a pie. You will use the example of Escherichia coli (E. coli) in describing the three vertices (corners) of the Epidemiologic Triangle. In Figure 1.17, it would be represented by component cause A. A host can then suffer a variety of ailments, from lung cancer to heart disease to diabetes. In countries where anthrax is common and vaccination levels of animal herds are low, humans should avoid contact with livestock and animal products and avoid eating meat that has not been properly slaughtered and cooked. 2.Study person-related variables or factors to help provide increased access to treatment.

Environmental factors affecting the contraction of a disease include factors like geographic location and climate (CDC, 2012). Anthrax is an acute infectious disease that usually occurs in animals such as livestock, but can also affect humans. Healthcare staff should follow best practices and procedures to help prevent infections from spreading in your facility. Provide an example of each factor that can influence violent behavior. While most human cases of anthrax result from contact with infected animals or contaminated animal products, anthrax also can be used as a biologic weapon. temperature, crowding, air pollution) Many people refer the agent as the germ. Over time, the concept of the agent has expanded to allow for application of the triad to non-infectious diseases and accidents.
