Date Developed: 1/1/2005. Source: Center for Public Health Preparedness (University of North Carolina). Presenter(s): Amy Pickard Nelson, PhD, MPH. Type: Narrated Slide Presentation Training Series. Level: Introductory. Length: Series; various lengths.


This training set serves as an in-depth introduction to the field of epidemiology for non-epidemiologists. Each of the five sessions is broken into two, 30-minute modules. The first session describes public health and the history and application of epidemiology. Session two describes tools of epidemiology, identifies sources of data, gives an overview of data analysis, and introduces the role of the CDC. The third section describes the differences between descriptive and analytic epidemiology, defines key concepts (including case definitions, prevalence, and incidence), provides examples of study designs, and gives a brief overview of measures of association and tests of significance in hypothesis testing. Session four describes public health surveillance, its benefits and challenges, provides examples of surveillance systems, and gives more information on the role of CDC. Part two of session four also describes techniques for analyzing and interpreting surveillance data, describing differences between crude versus specific rates and outlining factors that may influence surveillance data. The fifth section describes specialties in epidemiology, specifically disaster, environmental, and forensic epidemiology, providing examples of their functions and application.
