AISR fortnightly report No. 9 – 24 July to 6 August 2023

The Australian Influenza Surveillance Report (AISR) is compiled from several data sources 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
• sentinel laboratory testing results.

The AISR is published fortnightly during the influenza season, typically between May and October. Influenza activity updates may be published outside of the seasonal period.
