Influenza Activity Surveillance 2017
Surveillance of Influenza activity in Australia and New Zealand.
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 the vast majority of 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.
27 February – 12 March 2017
Influenza-like-illness levels remain steady below baseline level.
6 Case of influenza have been detected in this reporting period:
5 x Influenza A
1 x Influenza B
29% Influenza positivity during the reporting period.
21 Cases of influenza have been detected this year: 18 x Influenza A and 3 x Influenza B.
Nationally, ILI notifications increased over the period with 83 notifications being reported in weeks 9—10. ILI rates reported in this period slightly increased at 4 and 3 cases per 1000 consultations in weeks 9 and 10 respectively, compared to 2 cases per 1000 consultations in the previous fortnight. For the same reporting period in 2016, ILI rates were 2 cases per 1000 consultations. On a state-by-state basis, it is important to note the sustained, elevated ILI rate in the Northern Territory.
(Baseline ILL < 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.

Low levels of influenza-like illness activity
This survey was sent on Monday, 15 May 2017 at 01:13 AM and by 09:00 AM, Thursday 18 May we had received 23995 responses (23738 last week) from 14381 people responding for themselves and 9614 household members across Australia.
Across Australia, fever and cough was reported by 1.6% of vaccinated participants and 1.7% of unvaccinated participants. Fever, cough and absence from normal duties was reported by 1.0% of vaccinated participants and 1.1% of unvaccinated participants.
For participants this week, 11854/23995 (49.4 %) have received the seasonal vaccine so far. Of the 4553 participants who identified as working face-to-face with patients, 2920 (64.1%) have received the vaccine.

During week 19 (8–14 May 2017), influenza activity was very low among consultation-seeking patients nationwide. Influenza activity was also low among those hospitalised patients in Auckland and Counties Manukau District Health Boards.
ILI surveillance: 44 patients with influenza-like illness consulted sentinel general practices in 20 DHBs. The weekly ILI incidence was 10.7 per 100 000 patient population, below the seasonal threshold of ILI consultations. The ILI related influenza incidence (adjusted) was 2.6 per 100 000 patient population.
Respiratory pathogen surveillance:
Influenza virus: During this week, 29 ILI specimens were tested, seven were positive for influenza viruses.
