EP713 is the sole introductory epidemiology course (replacing EP711 and EP712). Epidemiology is a discipline that identifies the determinants of defects, disease and injury in human populations and provides a means of assessing the magnitude of public health problems and the success of interventions designed to control them. The goals of EP713 are to introduce the basic principles and methods of epidemiology and demonstrate their applicability to public health and research and to provide fundamental skills needed to begin to interpret and critically evaluate literature relevant to public health professionals. Topics include measures of disease frequency and effect, epidemiologic study designs, bias, and screening for disease. Class lectures are interspersed with active learning exercises consisting of a mixture of in-class problems, exercises, and discussions, and online and independent learning modules further enable students to achieve the learning objectives.
