After defining common terms in epidemiology, the interactive presentation describes the roles of epidemiology in public health. The module describes the difference between descriptive and analytic epidemiology, demonstrates the usefulness of charts and graphs, and provides a brief history of the field. Next, the course describes uses and types of data, with particular focus on rates, ratios and proportions. The module also describes different types of studies that are commonly used in epidemiology. The course concludes with two examples of epidemiology in practice: a case study on firearm injuries in Minnesota and the history of Smallpox eradication. Short exercises and a post-test are used to reinforce learning.
