Influenza Activity Surveillance 2021

This report provides a summary of influenza surveillance data collected from around Australia and New Zealand. Regional reporting in some areas ceases when influenza activity is low (out of season). Please note that many people do not get tested for influenza and that there may also be some delays in reporting confirmed influenza cases.

Therefore data presented here may be underestimating influenza activity.

It is important to note that the influenza and ILI surveillance systems in WA have been impacted by the COVID-19 pandemic. Therefore, interpretation of respiratory viral activity should be done with caution and take into account the effects of changes in health seeking behaviour including accessing alternate health services such as telehealth, focused testing for COVID-19 at COVID-19 clinics or specific acute respiratory infection clinics and the impact of physical distancing measures.
