Training and service in public health practice, 1951-90--CDC's Epidemic Intelligence Service.

The Epidemic Intelligence Service (EIS) was created at the Centers for Disease Control (CDC) in 1951 as a combined training and service program in the practice of applied epidemiology. Since 1951, more than 1,700 professional have served in this 2-year program of the Public Health Service. In the decade of the 1980s, EIS underwent dramatic changes in response to the increased breadth of the CDC mission and the rapid expansion of epidemiologic methods. Modifications in the experience of an EIS Officer have resulted from the increased need for more sophisticated analytic methods and the use of microcomputers, as well as CDC's expanded mission into chronic diseases, environmental health, occupational health, and injury control. Officers who have entered the EIS in the past decade tend to be older than their predecessors, tend to enter the program with more experience and training in epidemiology, and are more likely to stay in public health either at the Federal level or in State and local health departments. The EIS Program continues to be a critical source for men and women to respond to the need and demand for epidemiologic services both domestically and internationally.
