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.
- Influenza activity at the national level continued to increase this reporting fortnight indicating that the season is underway in a majority of regions across Australia. This increase in activity occurred approximately one month earlier than in 2016.
- Influenza was detected at increasing levels by the majority of sentinel laboratories this reporting fortnight. For the first time since reporting for 2017 began, influenza A was the most common respiratory virus detected by a majority of sentinel laboratories, followed by respiratory syncytial virus (RSV).
- Influenza A(H3N2) is currently the predominant circulating A subtype in the majority of jurisdictions. Nationally, notifications of laboratory confirmed influenza B viruses reached a plateau this reporting fortnight.
- Notification rates this year to date have been highest in adults aged 85 years or older, with a secondary peak in young children, aged less than 10 years.
- Influenza-like illness (ILI) in the community and ILI presentations to sentinel GPs this fortnight continued the overall increasing trend, however remain within the range of recent seasons.
- Hospitalisations with confirmed influenza have increased in recent weeks in line with the seasonal increase in community level activity.
- To date, the seasonal influenza vaccines appear to be a good match for circulating virus strains.
