You will learn a bit about epidemiology - the study of disease in a population When an epidemiologist studies an outbreak they must have a definition of what they are looking for, that is, a case definition. This definition is used to identify which patients actually have a case of the disease they are trying to track or if the patient has something entirely different. Read the info about case definitions in the box. . About case definitions: A case definition should include four components IN ONE SENTENCE: 1) clinical information about the disease (that is, as much as they know at the time) 2) characteristics about the people who are affected, 3) information about the location or place, and 4) a specification of time during which the outbreak occurred. The following describes how you would develop a case definition. You should base the clinical criteria on simple and objective measures. For example, you might require the presence of an elevated level of antibody to the disease agent, the presence of a fever of at least 101°F, three or more loose bowel movements per day, or muscle aching severe enough to limit the patient's activities. Regarding the characteristics of people, you might restrict the definition to those who attended a wedding banquet, or ate at a certain restaurant, or swam in the same lake. By time, the criterion might be onset of illness within the past 2 months; by place, it might be living in a nine-county area or working at a particular plant. Whatever your criteria, you must apply them consistently and without bias to all of the people included in the investigation. Case definition example: Abdominal cramps and diarrhea (at least three stools in a 24-hour period) in school-age children who are residents of the Graham county with onset during Nov. 3 and Nov. 8, 1990.
