Australian Influenza Surveillance Report - week ending 23 June 2017 (#03/2017)

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; ILI-related 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.

Australian Influenza Surveillance Report No 03 - week ending 23 June 2017


  • Influenza activity is increasing in most of the southern and central regions of Australia while sporadic and stable in the northern regions of the country.
  • While testing for influenza has increased over the reporting fortnight, respiratory viruses other than influenza, in particular rhinovirus, were most commonly detected by sentinel laboratories.
  • Nationally, notifications of laboratory confirmed influenza B viruses have continued to increase over the reporting fortnight, however influenza A(H1N1)pdm09 and influenza A(H3N2) are also co-circulating in some parts of the country.
  • Influenza-like illness (ILI) in the community was low and relatively stable this reporting fortnight, while ILI presentations to sentinel GPs were also low, but increasing.
  • To date, the seasonal influenza vaccines appear to be a good match for circulating virus strains.
