Public Health and Epidemiology

According to the Centres for Disease Control and Prevention, epidemiology is a field of public health that sees a population as a "patient" and multiple health incidents as a "condition" that requires care (CDC). Cohort, case-control, and cross-sectional trials are the three main forms of epidemiologic studies. Though public health is a wide field of research, this specialty focuses on understanding the basic trends and sources of public health disturbances. It also includes society, organisations, governments, and individuals working together to expand life and increase quality of life through coordinated actions and educated decisions.
