Epidemiology, branch of medical science that studies the distribution of disease in human populations and the factors determining that distribution, chiefly by the use of statistics.Unlike other medical disciplines, epidemiology concerns itself with groups of people rather than individual patients and is frequently retrospective, or historical, in nature. Etiological epidemiology seeks to identify the determinants be they infectious agents, environmental or social exposures, or genetic variants. The scope of epidemiology tracks how far the disease spread. it has … Oxford University All of the uses of epidemiology involve these five questions. To identify the causes of diseases and … aims of epidemiology 14. aims: to describe the distribution and size of disease problems in human population. © 2020 Springer Nature Switzerland AG.

A lot of people think of diseases when they hear “epidemiology.” However, the scope of epidemiology goes much further than that. Once you’ve obtained your degree, what can you do with your career? Objectives of Epidemiology to identify the etiology, or cause, of a disease and its relevant risk factors (i.e., factors that increase a person’s risk for a disease). The scope of epidemiology goes far. Researchers achieve the functions of epidemiology by using the “Five W’s:” Who, What, When, Where, and Why. By providing clear, insightful, balanced contributions, the journal serves those for whom an understanding of emerging knowledge in epidemiology is essential to understanding the patterns of health and disease in populations.

It includes the study of the attack rate of the various diseases (incidence) and the number of people suffering from each condition at any one time (prevalence). Thesis - Intensive for Clinicians M.Sc. Epidemiologists do important work, so they’re welcomed in all sorts of workplace settings. Is it a non-infectious disease like cancer or diabetes? A concept is an idea, but the word is usually reserved for complex, or interrelated, ideas. In this chapter, we will cover both screening and diagnostic testing.Though public health professionals are not usually directly involved with diagnosing patients, the tests used for screening and diagnostic testing are often the same (the difference being context), and the same mathematical tools are used to assess the accuracy of these tests. Cancer Epidemiology is dedicated to increasing understanding about cancer causes, prevention and control. It provides a way of organizing and analyzing these data to describe the variations in disease frequency among populations by geographical areas and over time (i.e., person, place, and time). Epidemiology is derived from the word epidemic (epi=among; demos=people; logos=study), which is a very old word dating back to 3 rd century B.C. Application to control makes explicit the purpose of epidemiology – to promote, protect, and preserve good health” (Last 2001). Press, New York, Mausner J, Kramer S (1985) Epidemiology. First, the occurrence of disease is not random (i.e., various factors influence the likelihood of developing disease). Thesis M.Sc. Epidemiology saves lives and improves global, long-term health. Epidemiology is the study of factors affecting health and illness in communities and populations. It aims to make the latest epidemiological discoveries accessible to an audience beyond the Journal’s traditional readership, encourage debate, and help authors maximise the impact of their research. Researchers achieve the functions of epidemiology by using the … Epidemiology is the study of the distribution, causes, and possible prevention and control, of diseases in populations. Non-Thesis - Pharmacoepidemiology M.Sc. The Journal publishes a broad range of original research on epidemiology as it relates to human health, and aims to promote communication among those engaged in the field of epidemiological research and those who use epidemiological findings. Determinants are the physical, biologic, social, cultural, and behavioral factors influencing health.
