This course was created by the Illinois Public Health Preparedness Center and is part of the Environmental Health (PH 470) course series. These courses can be taken separately and in any sequence desired. The overall PH 470 series provides an introduction to environmental and occupational health. 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.
