Abstract


Timeliness and Completeness of the routine surveillance reports are surveillance quality indicators which are widely used for monitoring the surveillance quality.

Maturing surveillance systems that have variable data quality should have more comprehensive indicators - including all surveillance system components and core and support surveillance functions - for monitoring surveillance quality.
