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.
- Across most jurisdictions, seasonal influenza activity appears to have peaked in recent weeks with the exception of South Australia where activity continues to rise. The timing and magnitude of the peak is similar to 2014.
- Influenza notification rates have been highest among those aged between 5 and 9 and over 85 years with a secondary peak in those aged 40-44 years.
- Influenza B continues to be the dominant influenza virus type nationally, comprising over two thirds of all notifications. In the Australian Capital Territory and Western Australia, influenza A continues to replace influenza B.
- All systems that monitor influenza-like illness (ILI) activity are reporting decreasing activity following a season peak in the week ending 23 August. Influenza is the primary cause of ILI in the community this fortnight however other respiratory viruses continue to circulate at elevated levels.
- Data for hospitalisations with confirmed influenza show high influenza activity which is typical for mid-season. Influenza B continues to account for more than half of admissions.
- The seasonal influenza vaccines appear to be a good match for circulating strains with 83% of samples matching the trivalent seasonal vaccine (TIV).
