Australian Influenza Surveillance

The Australian Influenza Report is compiled from a number of data sources, including laboratory-confirmed notifications to NNDSS, sentinel influenza-like illness reporting from General Practitioners and Emergency Departments, workplace absenteeism, and laboratory testing. A more in-depth end of season report is also published in Communicable Diseases Intelligence.

Case Definitions

During the PROTECT phase, the clinical definition for an acute respiratory illness (ARI) is: Fever (38 degrees C or well documented history) with cough and/or sore throat.
If the medical practitioner has assessed that there is pandemic (H1N1) 2009 in the local community (community transmission*) then anyone with ARI is considered to have pandemic (H1N1) 2009.

In areas where there is no community transmission* then the medical practitioner should undertake a laboratory test to confirm pandemic (H1N1) 2009 infection.

* Community transmission is defined as person-to-person transmission, outside household or health care settings, with no epidemiological link to a probable or confirmed case.
