Australian Influenza Surveillance Report - week ending 07 July 2017 (#04/2017)

The Australian Influenza Surveillance Report and Activity Updates are compiled from a number of data sources, which are used to monitor influenza activity and severity in the community. These data sources include laboratory-confirmed notifications to NNDSS; influenza associated hospitalisations; sentinel influenza-like illness (ILI) reporting from general practitioners; ILI-related community level surveys; and sentinel laboratory testing results.

Page last updated: 06 January 2017

The Australian Influenza Surveillance Report is published on a fortnightly basis during the influenza season, typically between May and October. Influenza activity updates will be published outside of the seasonal period.

Australian Influenza Surveillance Report No 04 - week ending 07 July 2017


  • Influenza activity is increasing in the majority of Australian jurisdictions, while remaining stable and sporadic in the rural south and northern regions of Western Australia, the Northern Territory and the tropical region of Queensland.
  • Positive test results for influenza have increased significantly over the reporting fortnight, particularly in Victoria. Respiratory viruses other than influenza, in particular rhinovirus and RSV, were most commonly detected by sentinel laboratories.
  • Nationally, notifications of laboratory confirmed influenza B viruses have continued to increase over the reporting fortnight; however the proportion of total notifications has decreased. Influenza A(H1N1)pdm09 and influenza A(H3N2) are also co-circulating in some parts of the country.
  • Influenza-like illness (ILI) in the community increased slightly but remained low this reporting fortnight, while ILI presentations to sentinel GPs increased significantly.
  • To date, the seasonal influenza vaccines appear to be a good match for circulating virus strains.
