Australian Influenza Activity Update – week ending 20 June 2014 (#06/2014)

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 and emergency departments; ILI-related call centre calls and community level surveys; and sentinel laboratory testing results.

Page last updated: 01 July 2014

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, with updates also provided during the season. A more in-depth end-of-season report is also published in Communicable Diseases Intelligence journal.

Current Australian Influenza Activity Update – week ending 20 June 2014

  • Nationally influenza activity has started to increase, although overall activity remains relatively low (Figures 1 and 4).
  • There have been recent increases in influenza activity in Victoria, New South Wales, South Australia and Tasmania (Figure 2).
  • Nationally influenza A remains the predominant influenza virus type. Of those viruses where subtyping data are available, A(H1N1)pdm09 is most common (Figure 3).
  • Influenza A(H1N1)pdm09 was the predominant virus associated with severe respiratory illness among young and middle-aged adults in Europe and the United States of America during the northern hemisphere 2013-14 season.
  • Influenza virus strains currently circulating within Australia are similar to the strains included in the 2014 vaccine.
