In 1951 the Centers for Disease Control and Prevention created the Epidemic
Intelligence Service to provide training and epidemiologic service on the
model of a clinical residency program. By January 2001, an additional 28 ap
plied epidemiology and training programs (AETPs) had been implemented aroun
d the globe (with over 945 graduates and 420 persons currently in training)
. Field Epidemiology Training Programs and Public Health Schools Without Wa
lls are the most common models. Applied epidemiologists, or field epidemiol
ogists, use science as the basis for intervention programs designed to impr
ove public health. AETPs train people by providing them with health compete
ncies through providing service to public health intervention programs and
strengthening health systems. AETPs are relatively expensive to create and
maintain, but they are highly sustainable and can produce immediate benefit
s. Of the 19 programs that began before 1997, 18 (95%) continue to produce
graduates. The Training Programs in Epidemiology for Public Health Interven
tions Network was organized in 1997 to provide support, peer review, and qu
ality assurance for AETPs. In 2001, new programs are planned or in developm
ent in India, Argentina, China, and Russia.
