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 increase, with all jurisdictions except Victoria, reporting increasing activity.
- As at 1 August 2014, there have been 18,009 cases of laboratory confirmed influenza reported, with 5,827 notifications occurring during the report fortnight.
- Nationally influenza A is the predominant influenza virus type. Of those viruses where subtyping data are available, A(H1N1)pdm09 is most common. This trend is consistent across all jurisdictions, except in New South Wales and the ACT where influenza A(H3N2) is circulating at higher levels. The proportion of A(H3N2) in WA has increased in recent weeks however, A(H1N1)pdm09 remains more prevalent.
- Influenza virus strains currently circulating within Australia are similar to the strains included in the 2014 vaccine.
- The rate of influenza associated hospitalisations has dropped slightly over the past fortnight, with around 10% of cases admitted directly to ICU. The majority of hospital admissions have been associated influenza A infections and the median age of cases is 42 years.
- As yet, there is no clear indication of the overall severity of the season.
- The WHO has reported that globally influenza activity remains low. Following the recent northern hemisphere season, influenza activity has returned to inter-seasonal levels across most of these regions. In the southern hemisphere, there has been a gradual increase of influenza activity.
