Epidemiology and Public Health

Epidemiology and Surveillance

The study of population health and disease is known as epidemiology. The ongoing, systematic gathering, analysis, and interpretation of health data is known as disease surveillance. Data from disease surveillance are used to assess the need for public health intervention.

Information from surveillance systems can be used to: track changes in disease incidence over time (such as outbreaks); identify risk factors for the disease and populations most at risk; direct immediate public health measures for specific patients or the community; and direct programmes.
