Public health is a vast field that covers many aspects of keeping populations of people healthy. It includes, but is not limited to, research, data collection, data analysis, health education, and the interaction between health care givers and the general public, as is depicted here. Epidemiology, the systematic study of illnesses and injuries in populations, is one of the sciences used at CDC to help improve the public’s health. The injury depicted here, would be recorded and later studied in order to help prevent such calamities in others.
