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.
- Influenza activity continued to increase nationally this fortnight. All jurisdictions with the exception of Western Australia are continuing to increase in activity.
- 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 two thirds of all notifications. In South Australia, Victoria and Western Australia, the proportion of influenza A has increased.
- All systems that monitor influenza-like illness (ILI) activity are reporting increasing activity while remaining within the range of previous seasons. Influenza is the primary cause of ILI in the community this fortnight.
- Hospitalisations with confirmed influenza increased in the past fortnight. While less severe overall, presentations appear to be more severe in children this year, with 11% of children presenting to sentinel hospitals with influenza admitted directly to ICU compared with 6% of adults.
- The seasonal influenza vaccines appear to be a good match for circulating strains. However approximately one-quarter of influenza B viruses tested are due to the lineage not contained in the trivalent seasonal vaccine (TIV). The mis-match compared to the TIV is most evident in Queensland and New South Wales.
