A Basic Understanding Of Epidemiology And Epidemiologic Investigations

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.

Epidemiology, What? Is that even an English word? Epidemiology is the study of health and health concerns in a population with an emphasis on establishing cause and effect. Epidemiology looks at how the disease manifests and spreads through out a population that are a risk and come up with effective prevention and treatment.

Epidemiology has been defined as ‘The study of the distribution and determinants of health and disease-related conditions in populations. It is concerned with epidemic (excess of normal expectancy) and endemic (always present) conditions. The basic premise

Epidemiology is the study of distribution and determinants of health-related states or events in specified populations and the application of this study to the control of health problems. The epidemiological triad model holds that infectious diseases result from the interaction of agent, host, and environment (CDC, 2012). Disease transmission occurs when the agent leaves the reservoir or host through a portal of exit, are the conveyed by some mode of transmission and enters through and appropriate portal of entry on infecting a susceptible host (CDC, 2012). This sequence is sometimes called the chain of

Epidemiology studies the distribution "of health events in populations and the determinants or the factors that influence those patterns" (Stanhope & Lancaster, 2014, p. 151). It can be used to see if a disease is more prevalent in women or men. At one time, epidemiology was only used to study certain widespread infections such as tuberculosis or cholera. Not only does it now involve many different types of infections, it also includes chronic diseases, mental health events, violence, and positive health states. Some key contributions epidemiology has made in the science of public health are: "the understanding of factors that contribute to health and disease, the development of health promotion and disease prevention measures, the detection

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.

3. List and describe how at least two of the seven uses of epidemiology are applicable to the public health topic(s) presented in the story. (2 points)

Epidemiology is study of a distribution and determinants of health related events. The goal of epidemiology is to decrease the spread of a disease, to prevent the disease from spreading amongst a community. For this to be successful the epidemiologist gets knowledge on when and how the disease spread. Also how they will control and treat the patient.

Sometimes, despite everybody's best efforts, outbreaks of disease caused by contaminated food occur. The public health system then does detective work to find the source of the contamination and to stop it. We apply the methods of epidemiology to learn what the sick people have in common and locate the source of the contamination. Then we make sure that all contaminated food is removed from the supply.

Epidemiology as defined by the World Health Organisation is the study of distribution and causes of illnesses and health related events. The results of the study are used to help control the illness or sickness1. It is vital to the medical industry as

An Outbreak Investigation requires preparation and field work. The epidemiologic steps of an outbreak situation entails establishing the existence of an outbreak (are there more cases than expected), verifying the diagnosis, collaborating with laboratories to find causative agent, conducting an active surveillance, which may include additional cases, analyzing data by time, place, and person (when, where, and who), generating a hypotheses, and conducting a case-controlled study, communicating findings, and implementing control and prevention measures. There isn’t a definitive order to conduct the steps of an outbreak investigation. It usually depends on the circumstances of the outbreak (CDC, 2012).

This paper will explore the role of epidemiology in the surveillance of the incidence 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 first discussion topic for this course, PHLT: 319 Epidemiology for Health Educators, centered on the definition of epidemiology. Quickly, students became aware that epidemiology was not only the study of disease, rather the “study of the distribution and determinants of health-related states or events in human populations and the application of this study to the prevention and control of health problems”(2013, Merrill, 2). In an effort to reduce major public health events, the bacterial disease, cholera, has been studied over many years by researchers, specifically naming Dr. John Snow. Appendix I titled Case Studies, in Ray M. Merrill’s Introduction to Epidemiology, provides information, incidence and prevalence rates, and protocols for

This paper defines and explains the six core functions of epidemiology: Public health surveillance, field investigation, analytic studies, evaluations, linkages, and policy development. The core functions of epidemiology lay down a foundation on which epidemiologists can begin to work from. This paper will look at the benefits of incorporating all six of these functions into a working plan when health officials, medical personnel, first responders, etc., encounter a disease or illness that needs to be identified, treated and contained.
