Health Data & Epidemiology

Epidemiology is the branch of public health that focuses on investigating patterns of disease and measuring the health of a community. The word epidemiology is derived from the word “epidemic”, Greek for “upon the people”. At the start of epidemiology, most studies were focused on infectious and communicable diseases; however, modern epidemiology also includes chronic diseases, environmental exposures, and behavioral risk factors. A key function of epidemiology is to collect data through surveillance and reporting systems to look for trends and patterns of disease in the community. Examples include reporting communicable diseases, such as Salmonella, cancer registries and hospital discharges.
