This course was created by the Illinois Public Health Preparedness Center and is part of the Public Health Practice (PH 410) course series. These courses can be taken separately and in any sequence desired. The overall PH 410 series targets mid- and senior-level public health professionals coming from a variety of backgrounds and disciplines. Together, these courses provide a comprehensive introduction to public health concepts and practice by examining the philosophy, purpose, history, organization, functions, tools, activities and results of public health practice at the national, state, and community levels. The PH 410 series also addresses important health issues and problems facing the public health system. Case studies and a variety of practice-related exercises serve as a basis for learner participation in real world public health problem-solving simulations. The various components of these courses serve to stimulate interactions among learners and instructors around important problems and issues facing public health.
