? Both influenza A and B strains are circulating at similar levels.
In this reporting week:
? Hospital Surveillance ? influenza like illness (ILI) presentations to selected emergency
departments were low and at inter-seasonal levels.
? Laboratory surveillance ? the total number of influenza isolations was unchanged this week with
the proportion of respiratory samples positive for influenza unchanged at 4.8%.
? Community surveillance ? influenza notifications were low across all NSW local health districts
(LHD). General Practice and community-based surveillance systems showed low ILI activity.
One aged care facility reported a respiratory outbreak.
? National and international influenza surveillance ? national influenza surveillance reports are
not produced at this time of year, however many jurisdictions are reporting low influenza
activity.
? Recommended composition of 2017 influenza vaccines ? the 2017 Australian influenza
vaccines cover two A and two B strains, including one A strain change from the 2016
influenza vaccines.

Report No. 3: Week ending 21 May 2017
Overview: The 2017 influenza season so far
Influenza-like illness (ILI) surveillance indicates activity is at baseline levels.
The number of notified laboratory confirmed influenza cases for the year to 21 May is 42% higher than at the
same time in 2016. This difference is largely due to increased notifications in the first 7 weeks of the year. In the
past 4 weeks the number of notified cases was similar to 2016. Of the notified influenza cases, 84% have been
type A. Five VicSPIN swabs were positive for influenza: two influenza A(H1) and three influenza A(untyped). Six
were positive for picornavirus.
Influenza and ILI surveillance systems are at baseline levels.
GP?s can you please try to swab all ILI patients and ensure you record all ILI patients.
Electronic entry of tally sheet data will be possible in several weeks when the new database is rolled out, with
instructions about how to use it to be provided beforehand.

KEY POINTS
INFLUENZA AND INFLUENZA-LIKE ILLNESSES (ILI)
Summary: Indicators of ILI and influenza activity remain at inter-seasonal levels.
There is a low level of ILI and influenza activity.
While the number of detections remains low, there has been a relative increase in influenza A/H1N1
virus in the past 3 weeks, accounting for around 50% of detections.
Non-influenza respiratory virus activity, including RSV, also remains low

REPORTING
Reports were received from 171 GPs from 8
states and territories during the reporting
period. During weeks 9 and 10 ASPREN
reporters saw a total of 25,698 patients.
INFLUENZA-LIKE-ILLNESS (ILI)
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
(see Fig. 5). On a state-by-state basis, it is important to note
the sustained, elevated ILI rate in the Northern Territory (see
Fig. 2).

Week ending 28 May 2017
This survey was sent on Monday, 29 May 2017 at 01:13 AM and by 09:00 AM, Thursday 01 June we had received 24590 responses (24587 last week) from 14682 people responding for themselves and 9908 household members across Australia.
Low levels of influenza-like illness activity
Across Australia, fever and cough was reported by 1.6% of vaccinated participants and 1.8% of unvaccinated participants. Fever, cough and absence from normal duties was reported by 1.1% of vaccinated participants and 1.3% of unvaccinated participants.
For participants this week, 13811/24590 (56.2 %) have received the seasonal vaccine so far. Of the 4677 participants who identified as working face-to-face with patients, 3487 (74.6%) have received the vaccine.
