When considering the Epidemiological Triad, there are three main factors that are taken into account: The Agent, The Host, and The Environment. 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). To help identify the key risk factors, Sam begins to examine three categories of risk central to epidemiology. Describe the characteristics of the people who are affected by covid-19. The agent is the microorganism that actually causes the disease in question. Include the host factors, agent factors (presence or absence), and environmental factors. To prevent the spread of disease, at least one side of the Epidemiologic Triangle must be broken. Agent, or microbe that causes the disease (the what of the Triangle) 2. 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. Interpret basic epidemiologic measures of morbidity (disease) and mortality (death). The National Institute for Health has broken down how the triangle can be applied to COVID-19.8. These pathogens include viruses, bacteria, fungi, parasites, and other microorganisms.
