Epidemiology is the cornerstone of public health, pursuing insights into the causes, distribution, and prevention of disease in populations. We conduct innovative, interdisciplinary research with a broad cells-to-society approach to questions about population health. Like the clinical findings and pathology, the epidemiology of a disease is an integral part of its basic description. The subject has its special techniques of data collection and interpretation, and its necessary jargon for technical terms. Descriptive Epidemiology: Is the collection of all data describing the occurrence of the disease, and usually includes information about individuals infected, and the place and period during which it occurred, Analytical Epidemiology: compares a group of people who have the disease with a group that is similar in age, sex, socioeconomic status, and other variables, but does not have the disease. e.g., genetic or environmental, Experimental Epidemiology: tests a hypothesis about a disease or disease treatment in a group of people. This strategy might be used to test whether or not a particular antibiotic is effective against a particular disease-causing organism.
