Since 1916, the Johns Hopkins Bloomberg 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 earth and polio from the Western Hemisphere.
The oldest and largest school of its kind, the School has been consistently ranked number one by U.S. News & World Report. It receives 25.2 percent of research funds awarded to U.S. schools of public health; its faculty pursue research in 50 countries; and it awards one-sixth of all public health doctoral degrees worldwide. Through education, research, and service, the Johns Hopkins Bloomberg School of Public Health offers innovative approaches to restoring health, preventing disease and injury, and saving medical dollars.
Students come from a wide variety of professional and academic backgrounds. The School offers part-time graduate programs in several off-campus locations in addition to its full-time offerings on the Hopkins East Baltimore campus, and distance education courses over the Internet. |
