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.

Key Messages

It is important to note that due to the COVID-19 epidemic in Australia, data reported from the various influenza surveillance systems may not represent an accurate reflection of influenza activity. Results should be interpreted with caution, especially where comparisons are made to previous influenza seasons. Interpretation of 2020 influenza activity data should take into account, but are not limited to, the impact of social distancing measures, likely changes in health seeking behaviour of the community including access to alternative streams of acute respiratory infection specific health services, and focussed testing for COVID-19 response activities. Current COVID-19 related public health measures and the community’s adherence to public health messages are also likely having an effect on transmission of acute respiratory infections, including influenza.

  • Activity – Following a high start to the 2020 interseasonal period, currently, influenza and influenza-like illness (ILI) activity are lower than average across all systems for this time of year. At the national level, notifications of laboratory-confirmed influenza have substantially decreased since mid-March and remain low.
  • Impact – There is no indication of the potential impact on society of the 2020 season at this time.
  • Severity – There is no indication of the potential severity of the 2020 season at this time. In the year to date, of the 20,631 notifications of laboratory confirmed influenza, 36 (0.17%) laboratory-confirmed influenza-associated deaths have been notified to the National Notifiable Diseases Surveillance System (NNDSS).
  • Virology – In the year to date, the majority of nationally reported laboratory-confirmed influenza cases were influenza A (87.5%). The proportion of cases attributed to influenza B has remained similar in the past fortnight (33.9%), compared to the previous fortnight (35%; 18 to 31 May 2020).
  • Vaccine match and effectiveness – It is too early in the season to assess vaccine match and effectiveness.
