Influenza Activity Surveillance 2019
This report provides a summary of surveillance data collected from around Australia and New Zealand. Regional reporting in some areas ceases when flu 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.

ASPREN is a national syndromic surveillance program co-ordinated by the Discipline of General Practice at the University of Adelaide and The Royal Australian College of General Practitioners. One of the conditions under surveillance is influenza like illness (ILI). General practitioners participating in the ASPREN program contribute data on the proportion of consultations which are ILI related.
1 – 13 January 2019
Influenza-like-illness levels remain steady at baseline levels.
5 cases of influenza have been detected in this reporting period: 5 x Influenza A.
26% Influenza positivity during the reporting period.
Reports were received from 233 reporters from 8 states and territories during the reporting period. During weeks 1 and 2 reporters saw a total of 20,093 patients.
Nationally, ILI notifications increased during the period with 51 notifications being reported in weeks 1—2. ILI rates reported in this period remained steady at 3 and 5 cases per 1000 consultations (weighted) in weeks 1 and 2 respectively. This was similar to the previous fortnight where rates were 2 and 4 cases per 1000 consultations. For the same reporting period in 2018, ILI rates were lower at 2 and 3 cases per 1000 consultations for weeks 1 and 2.
(Baseline ILL < 3 & 4 in 1000 consultations, Normal 4< ILL rate <24).

FluTracking is a pilot online health surveillance system which aims to detect epidemics of influenza. It is a joint initiative of The University of Newcastle, Hunter New England Area Health Service (NSW Health) and Hunter Medical Research Institute. Participation is voluntary and involves the completion of a weekly online survey during the influenza season. Data are collected on basic demographics, symptoms of ILI and absenteeism.
