Choosing Your Path: 9 Public Health Concentrations
Public health keeps families healthy and communities strong. It provides health services in rural areas, immunizes children, and promotes on-the-job health and safety. Public health also saves lives. As a result of public health efforts, the death rate of U.S. adults who smoke decreased from 42% to 25% between 1964 and 1997, according to the American Public Health Association (APHA).
While public health professionals are united by a singular goal — to promote better health for individuals and communities — their work spans a broad spectrum, from community health and epidemiology to disaster management and health policy.
