Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. If the triangle represents the who, what and where of infectious disease and health issues, epidemiologists and public health workers are responsible for determining the balance of the factors, or the why, and how to disrupt or break the triangle to stop the issue from progressing. As you might have guessed, the chart has three specific parts outlining how diseases spread. It may indicate the source of the disease, View the full answer Transcribed image text: PROBLEM 3 (40 pts) a) a) Provide a detailed but brief discussion of all of the components of the epidemiological triangle of disease? Nam lacinia pulvinar tortor nec facilisis. John has also assumed responsibility for surveillance of sexually transmitted infections (STIs). All aspects of the environment around the host are key factors to consider when trying to determine the cause of a disease. 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. Susceptibility and response are both influenced by factors like genetic composition, physiological make up, and health behaviors such as nutrition and exercise (CDC, 2012). The primary purpose of surveillance of STIs at the local public health department is to be able to: A variety of factors intrinsic to the host, sometimes called risk factors, can influence an individuals exposure, susceptibility, or response to a causative agent. People become a potential host for smoking-related diseases when they smoke cigarettes or when they inhale second-hand smoke. endobj But because lung cancer can develop in persons who have never been exposed to either smoking or asbestos, a proper model for lung cancer would have to show at least one more Sufficient Cause Pie that does not include either component B or component C. Note that public health action does not depend on the identification of every component cause. Describe the methods of surveillance and how the outbreak or increase in incidence was determined. viral infection that targets a persons immune system, socioeconomic factors that can impact the spread of HIV, online public health undergraduate degree. A 25.0-g sample of nitrogen, N2\mathrm{N_2}N2, has a volume of 50.0 L and a pressure of 630. mmHg. A triad consists of a foreign agent, a vulnerable host, and an environment that connects the host and the agent. Scientists were also able to determine the center of the triangle, the factor of time, that shows the COVID virus spreads fairly quickly and hosts are generally capable of spreading the virus for two weeks after infection. First epidemiologists have to identify the three vertices of the triangle: Agent: A type of virus called a coronavirus, identified as SARS-CoV-2. endobj Life expectancy tends to be shorter for those who smoke, and smoking-related diseases are considered to be the leading preventable cause of death in the United States.

WebIn a written paper of 1,200-1,500 words, apply the concepts of epidemiology and nursing research to a communicable disease. A single component cause is rarely a sufficient cause by itself. That is, there may be more than one correct statement. 1.The cost of the test is high. For a person who has been exposed to anthrax but is not yet sick, antibiotics combined with anthrax vaccine are used to prevent illness. According to the Centers for Disease Control and Prevention (CDC), epidemiology is the study of the distribution and determinants of health-related states and events in specified populations. The PHN understands that the agent could be one of many types except: 1.Biological and chemical. List 4-5 questions a health provider would want to ask in a patient interview to determine if the person is a possible case of covid-19.

Another way to think of the triangle model is the what (the agent), who (host), where (environment) and when (time) of health issues.3. Sufficient Cause II includes smoking without asbestos, and Sufficient Cause III includes asbestos without smoking. Deaths are rare with appropriate antimicrobial therapy. A number of models of disease causation have been proposed. The environment also includes social norms that affect the spread of disease (i.e. This variable, having another type of cancer, would be called a(n): An epidemiologist uses the epidemiological triangle to explain the occurrence of disease by looking at the three main components of the model: the host, the environment, and the agent. Generally, the agent must be present for disease to occur; however, presence of that agent alone is not always sufficient to cause disease. Upon completing this module, you will be able to: Define epidemiology. The measurement of disease frequency relates to the quantification of disease occurrence in human populations. She is seeking preliminary data on how many of the students who may have asthma are exposed to secondary smoke. The agent is the microorganism that actually causes the disease in question.

Agent, or microbe that causes the disease (the what of the Triangle) 2. As epidemiology has evolved to cover more public health issues beyond diseases, agents can also be represented as physical or chemical factors.2, Its important to note that the epidemiologic triad is a useful tool for many diseases and health events but the model only works for those issues that have one single necessary cause. (Consider the data sources that would provide the best information or the sources of information that might not be readily available on the Internet. The Centers for Disease Control and Prevention (CDC) define epidemiology as the study of the distribution and determinants of health-related states and events in specified populations.1 To complete this study of health-related states and events, scientists use a tool called the epidemiologic triangle, or the epidemiologic triad. Anthrax can also be spread as a bioterrorist agent. A control or "no disease" group is needed for study on risk factors associated with oral cancer. Environment refers to extrinsic factors that affect the agent and the opportunity for exposure. WebNurses should be prepared to take immediate action when breaches in security occur. WebThe epidemiological Triangle model includes three key elements: the agent, host, and environment. Inhalation anthrax is often fatal. The epidemiologic triangle is made up of three components that contribute to the spread of disease: an external agent, a host and an environment in which the agent and host meet. This is the same technique that epidemiologists use when they are researching the outbreak of a disease. By better understanding how HIV is communicated, epidemiologists were able to make progress on treatment and prevention. The third aspect of the epidemiological triangle, environment, refers to characteristics described above, such as cultural acceptance, pockets of poverty and/or a history of violence. Here, we demonstrate that O 3 exposure impaired the ability of microglia, the brains parenchymal immune cells, to associate with and form a protective barrier around A plaques, leading to augmented dystrophic neurites and increased A plaque load.
