Australian Influenza Surveillance Report

The Australian Influenza Surveillance Report and Activity Updates are compiled from a number of data sources, which are used to monitor influenza activity and severity in the community. These data sources include laboratory-confirmed notifications to NNDSS; influenza associated hospitalisations; sentinel influenza-like illness (ILI) reporting from general practitioners and emergency departments; ILI-related call centre calls and community level surveys; and sentinel laboratory testing results.

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.

Australian Influenza Surveillance Report No 05 - 23 July to 05 August 2016

Summary

  • In the fortnight ending 5 August 2016, influenza activity at the national level continued to increase indicating that the season is underway.
  • Influenza-like illness (ILI) is increasing nationally. Influenza was the most common cause of ILI presentations to sentinel general practitioners.
  • Influenza A(H3N2) was the dominant circulating influenza virus nationally in recent weeks, noting jurisdictional variation. Notifications of influenza B increased slightly in recent weeks, but remained at low levels overall.
  • Notification rates this year to date have been highest in adults aged 85 years or older, with a secondary peak in the very young, aged less than 5 years. This is consistent with influenza A(H3N2) being typically more prevalent in older age groups.
  • 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.
