Surveillance

SurveillanceSurveillance in general may be defined as: Continuous analysis, interpretation and feedback of systematically collected data, generally using methods distinguished by their practicability, uniformity and rapidity.
 It may be active or passive, and although case based in a given population, many systems, especially those doing surveillance for communicable diseases, rely on laboratory confirmation as this improves specificity of case definition. This is the system adopted by the National Institute for Communicable Diseases (NICD).
