WebQuestion: Describe the components of the epidemiological triangle for Covid-19 disease. The epidemiological Triangle model includes three key elements: the agent, host, and environment. 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. For this assignment, review the reading around the epidemiological triangle, and apply this theory to the evolving COVID-19 virus. <>>>
WebQuestion: Describe the components of the epidemiological triangle for Covid-19 disease. The Epidemiologic Triangle is a chart that scientists and other researchers can use to evaluate different diseases and follow their progression. With regard to non-infectious disease, disability, injury, or death, agents can include chemicals from dietary foods, tobacco smoke, solvents, radiation or heat, nutritional deficiencies, or other substances, such as poison. As you might have guessed, the chart has three specific parts outlining how diseases spread. For example, even exposure to a highly infectious agent such as measles virus does not invariably result in measles disease. Deaths are rare with appropriate antimicrobial therapy.

WebThe epidemiology triangleis a traditional model that characterizes infectious disease causation by showing the interaction and interdependence of agent, host, environment, and time Epidemiology Triangle The agent is a causative factor, such as a pathogen or chemical The host is an organism and usually a human Host factors According to the CDC, the concept of an agent has been widened to include both chemical or physical causes of disease or injury. Which of these parts of the brainstem is correctly matched with its main function? o Morbidity- provides information about the risk of disease, rate of disease development and levels of existing disease in the community. 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. Susceptibility and response to an agent are influenced by factors such as genetic composition, nutritional and immunologic status, anatomic structure, presence of disease or medications, and psychological makeup. It is used by veterinarians, laboratorians, soldiers, and others who may be at increased risk of exposure, but is not available to the general public at this time. What may have caused the flooding of the continents during the Cretaceous Period? 3.Physical. 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. After this in-class introduction, students will gather information about chickenpox and report back to the class on what they have learned. Intestinal anthrax results in death in 25% to 60% of cases.

The epidemiologic triangle is made up of three parts: agent, host and environment. Anthrax is diagnosed by isolating B. anthracis from the blood, skin lesions, or respiratory secretions or by measuring specific antibodies in the blood of persons with suspected cases. For COVID-19 the way to interrupt the virus from infecting the host is to get vaccinated. (Select all that apply.) It also can be used to describe the period from an infection to the threshold of an epidemic for a population.3.

However, a variety of factors can influence whether or not exposure to the agent will directly result in disease. One of the issues that has arisen is how to address patients who come in asking about testing for BRCA1 and BRCA2, the tumor suppressing genes that, if mutated, may indicate hereditary breast and ovarian cancer. In epidemiology the host is usually a human who gets sick but can also be an animal that acts as a carrier of disease but may or may not present illness.

Imbalance towards the Agent When looking at the epidemiological teeter totter, there are moments when there is an imbalance that causes many different scenarios. Yin is a nurse in a rural primary care clinic. The environment includes any factors that affect the spread of the disease but are not directly a part of the agent or the host. Biological factors refer to the animals present in the area that transmit the agent, and socioeconomic factors refer to issues like crowding, poor sanitation, and accessibility to health care (CDC, 2012). Anthrax can infect a person in three ways: by anthrax spores entering through a break in the skin, by inhaling anthrax spores, or by eating contaminate, undercooked meat.

Some of the agents that trigger non-atopic asthma are Chronic Mycoplasma pneumonia and Chlamydia pneumonia (Hong, 2012). When considering the Epidemiological Triad, there are three main factors that are taken into account: The Agent, The Host, and The Environment. The National Institute for Health has broken down how the triangle can be applied to COVID-19.8. Pneumocystis carinii is an organism that harmlessly colonizes the respiratory tract of some healthy persons, but can cause potentially lethal pneumonia in persons whose immune systems have been weakened by human immunodeficiency virus (HIV). A control or "no disease" group is needed for study on risk factors associated with oral cancer. The epidemiologic triangle is a model for explaining the organism causing the disease and the conditions that allow it to reproduce and spread. These categories include all of the following except: 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. 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. Pellentesque dapibussectetur adipiscingsectetur adipiscsectetur adipiscsecsectetsecsectetur adipissectetur adipiscing elit. Presence of Pneumocystis carinii organisms is therefore a necessary but not sufficient cause of pneumocystis pneumonia. 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.
