Epidemiology of Salmonella and Shigella Infections in the United States

The epidemiologic characteristics of Salmonella and Shigella infections in the United States have been studied by examination of data from 3 major sources: a national laboratory-based surveillance system, outbreak investigations, and carefully designed field studies. In this presentation we will separately discuss Salmonella and Shigella infections and for each give examples of contributions from these 3 sources that have allowed identification of specific problems and development of appropriate control measures.
