School of Public Health Since 1916, the School of Public Health has been among the leading guardians of the world's health, demonstrating that prevention is infinitely more effective than treating problems once they occur. The School researches the causes of health problems such as those related to epidemics, malnutrition, and environmental toxins and devises effective solutions to them. It helps governments and agencies tackle public health problems through an arsenal of new technologies and strategies, and helps translate these strategies into public policies and health care initiatives. Through such guidance from the School and other agencies, smallpox was erased from the face of the earth and polio from the Western Hemisphere. Through education, research, and service, the School of Public Health offers innovative approaches to restoring health, preventing disease and injury, and saving medical dollars.
