Principles of Epidemiology – HLTH 503

CG • Section 8WK • 11/08/2019 to 04/16/2020 • Modified 08/20/2021

Course Description

The course is a study of human population patterns of disease and injury and the application of this study to the control of health problems.

For information regarding prerequisites for this course, please refer to the Academic Course Catalog.


Disease is not randomly distributed within a population, but rather occurs according to patterns which can be observed and described using frequencies within subpopulations and groups. An understanding of the uneven distribution of an illness can be used by investigators to correctly determine causation and ultimately develop strategies and programs for prevention and control of that illness. As one of the core course requirements of a public health degree, the discipline of epidemiology provides the tools necessary to accurately study and describe the occurrence of disease, reach conclusions regarding causation, and develop practical, effective interventions to reduce or eliminate the effects of disease upon human populations.

PowerPoint Presentation Project

The student will explore an infectious disease using a descriptive epidemiologic approach. The student will select the disease from an approved list that will be provided. The student will then collect sources, develop an outline, and compile a reference page according to current AMA format. The student will develop two PowerPoint presentations of 15–20 slides each with a fully typed narration suitable for a professional audience and a general audience, respectively.
