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.
- Nationally, influenza activity has continued to decline following a seasonal peak in mid-August.
- This fortnight, influenza activity was stable or decreasing across most regions in the country, with the exception of the Top End of the Northern Territory where activity continued to increase.
- This year children aged less than 15 years accounted for one-third of all influenza notifications, this compares with one-quarter of all notifications in 2014. Notification rates have been highest among those aged between 5 and 9 and over 85 years with a secondary peak in those aged 35-44 years.
- Influenza B continues to be the dominant influenza virus type circulating nationally. Notifications due to both influenza A and B declined nationally this fortnight, however increases were seen in influenza A in the Northern Territory.
- All national systems that monitor influenza-like illness (ILI) activity continued to report decreasing activity this fortnight following a seasonal peak in mid-August. Western Australia reported unchanged ILI activity when compared with the previous fortnight. Influenza is the primary cause of ILI in the community this fortnight.
- Hospitalisations with confirmed influenza have continued to decline following a peak in mid-August. The overall rate of influenza cases admitted directly to ICU so far this year was 7%, which is lower than the last three years (10-12%).
- The seasonal influenza vaccines appear to be a good match for circulating strains with 77% of samples matching the trivalent seasonal vaccine (TIV).
- The WHO released its recommendation for the composition of the 2016 southern hemisphere seasonal influenza vaccine, which included changes to the A(H3N2) and B vaccine viruses of the trivalent influenza vaccine.
