The definition of epidemiology ends with the following phrase: “…and the application of this study to the control of health problems.” While some academically minded epidemiologists have stated that epidemiologists should stick to research and not get involved in policy development or even make recommendations, ( 24 ) public health epidemiologists do not have this luxury. This approach is commemorated in the symbol of the Epidemic Intelligence Service (EIS), CDC’s training program for disease detectives — a shoe with a hole in the sole. The purpose of public health surveillance, which is sometimes called “information for action,” (18) is to portray the ongoing patterns of disease occurrence and disease potential so that investigation, control, and prevention measures can be applied efficiently and effectively. By identifying the vehicle, investigators may be able to determine how many other persons might have already been exposed and how many continue to be at risk. McGill University. Epidemiological research helps us to understand how many people have a disease or disorder, if those numbers are changing, and how the disorder affects our society and our economy.

Reviewing reports of test results for, ____ 2. This is not all it does, of course, but it is one aspect of epidemiology, and historically a crucial aspect for the growth of the discipline. According to what will be referred to here as the “classical” definition of confounding, F is a confounder (of the E–D relationship) if and only if both of the following conditions are satisfied: (a) F is a cause of disease in the unexposed cohort, and (b) F is associated with exposure in the cohort at the start of follow-up. Epidemiology as a science is defined as “the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems”(1). MMWR Recommendations and Reports 2001:50(RR13). Descriptive studies (case reports, case series, cross-sectional studies, ecological studies) consider the … Classic or field epidemiology. of Jerry Morris’s now classic little monograph,Uses of Epidemiology, but there were hardly any comprehensive current textbooks to guide me.

Through the use of scientific methods, researchers consider other variables that can impact the spread of diseases: human interactions, travel, climate, socioeconomic status of the people affected, and more. Classical public health epidemiology – generally aims to investigate distributions and causes of diseases in populations. Norwalk (Connecticut): Appleton & Lange; 1992. p. 11.

The investigation may be as limited as a phone call to the health-care provider to confirm or clarify the circumstances of the reported case, or it may involve a field investigation requiring the coordinated efforts of dozens of people to characterize the extent of an epidemic and to identify its cause. Epidemiologists, who are accustomed to using systematic and quantitative approaches, have come to play an important role in evaluation of public health services and other activities.
