Abstract

This report provides the revised Surveillance case definitions approved by the Communicable Diseases Network Australia since 1 July 2012. These definitions come into effect from 1 January 2013. The Case Definitions Working Group (CDWG) is a subcommittee of the Communicable Diseases Network Australia (CDNA). Membership is comprised of representatives from all states and territories, the Australian Government Department of Health and Ageing, the Public Health Laboratory Network, OzFoodNet, the Kirby Institute, the National Centre for Immunisation Research and Surveillance of Vaccine Preventable Diseases and other communicable disease experts. CDWG develops and revises surveillance case definitions for all diseases reported to the National Notifiable Diseases Surveillance System. Surveillance case definitions incorporate laboratory, clinical and epidemiological elements as appropriate.
