What is effective surveillance?
An effective disease surveillance system is essential to detecting disease outbreaks quickly before they spread, cost lives and become difficult to control. Effective surveillance can improve disease outbreak detection in emergency settings, such as in countries in conflict or following a natural disaster.
What are surveillance activities?

Clinician-based reporting is better than laboratory-based because it is more timely. The results suggest a clinician-based notification system would be the most appropriate form of surveillance for a disease like SARS for public health purposes.
What are the three purposes of surveillance?
Information from surveillance systems can be used to monitor the burden of a disease over time, detect changes in disease occurrence (e.g., outbreaks), determine risk factors for the disease and populations at greatest risk, guide immediate public health actions for individual patients or the community, guide programs
What are the objectives of surveillance?
Objectives of Surveillance Systems
The key objective of surveillance is to provide information to guide interventions. The public health objectives and actions needed to make successful interventions determine the design and implementation of surveillance systems.
How do you assess surveillance system?

- List the objectives of the system.
- Describe the health event(s) under surveillance. State the case definition for each health event.
- Draw a flow chart of the system.
- Describe the components and operation of the system.
What is surveillance operation?
