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 04 - 09 July to 22 July 2016

Summary

  • In the fortnight ending 22 July 2016, influenza activity at the national level was increasing and indicative of early influenza seasonal activity, however there were some regions within Australia where activity remained unchanged.
  • Influenza was the most common cause of influenza-like illness (ILI) presentations to sentinel general practitioners.
  • Influenza A(H3N2) was the predominant influenza virus circulating nationally in recent weeks, noting jurisdictional variation.
    Influenza A(H3N2) is typically more prevalent in older age groups.
  • So far this year, influenza notification rates have been highest in children aged less than 5 years and adults aged 85 years or older, with a secondary peak in adults aged 35-39 years.
  • To date, the seasonal influenza vaccines appear to be a good match for circulating virus strains.
