ACT Health conducts surveillance for laboratory-confirmed cases of influenza in the ACT. Each influenza season (approximately June/July to Sept/Oct), the Disease Surveillance Unit regularly prepares an influenza report which includes current data on influenza notifications in the ACT.
Notification data only include cases of influenza among ACT residents that have been confirmed by a laboratory test. Generally, notification data represent only a small proportion of cases of influenza occurring in the community. All data are preliminary and subject to change as updates are received.
2018 ACT Influenza Reports
2017 ACT Influenza Reports
In the ACT, the 2017 influenza season was larger and more sustained than any influenza season in the previous five years.
The season peaked twice, first due to influenza A (presumably A/H3) activity and subsequently due to influenza B activity. The increase in influenza notifications in 2017 may be associated with an earlier season onset, increased health-seeking behaviour, increased laboratory testing and the increased use of rapid tests.
Despite high activity, the clinical severity of influenza cases in the ACT was similar to previous years. Although there was increased influenza activity in the community, outbreaks of influenza-like illness (ILI) in ACT Aged Care Facilities (ACFs) were similar in 2017 compared to 2016, in terms of both the overall number of outbreaks reported as well as the number of residents affected
