    Summary:
    ? Influenza activity continues to be low across all NSW local health districts.
    ? 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

    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.

    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

      Report No. 6: Week ending 11 June 2017
      Overview: The 2017 influenza season so far
      Influenza and ILI surveillance systems are at baseline to average levels.
      The number of notified laboratory confirmed influenza cases for the year to 4 June is 54% higher than at the
      same time in 2016, largely due to a higher number of notified cases in the first two months of the year. Most
      notified cases year-to-date have been type A (71%).
      Twelve swabs were received this week, of which three were positive for influenza; two influenza (H3) and one
      influenza B, but picornavirus is the most commonly detected respiratory virus so far in 2017.
      This year we are encouraging GPs to swab all ILI patients (where possible) and ensure all ILI patients are recorded
      on the tally sheet.
      Final stage testing of the new database is now underway, and will hopefully be rolled out in several weeks.

      KEY MESSAGES
       Influenza activity has increased slightly in the last month, but remains at inter‐seasonal levels across
      Australia.
       Detections of influenza B viruses have increased in recent weeks, consistent with the predominance of
      influenza B viruses worldwide currently.1
       Respiratory viruses other than influenza are more commonly causing influenza‐like illness presentations to
      sentinel general practitioners, with rhinovirus and respiratory syncytial virus (RSV) detected most
      frequently.
       There is no indication of the potential severity of the 2017 season at this time.
       To date, the seasonal influenza vaccines appear to be a good match for circulating virus strains.

        Twelve swabs were received this week, of which three were positive for influenza; two influenza (H3) and one
        influenza B, but picornavirus is the most commonly detected respiratory virus so far in 2017.
        This year we are encouraging GPs to swab all ILI patients (where possible) and ensure all ILI patients are recorded
        on the tally sheet.
        Final stage testing of the new database is now underway, and will hopefully be rolled out in several weeks.

        35,230 patients.

        INFLUENZA-LIKE-ILLNESS (ILI)
        Nationally, ILI notifications increased over the period with 148
        notifications being reported in weeks 21?22. ILI rates
        reported in this period remained steady at 4 cases per 1000
        consultations for both weeks 21 and 22. This was the same
        rates as seen in the previous fortnight. For the same reporting
        period in 2016, ILI rates were higher at 5 and 7 cases per
        1000 consultations for weeks 21 and 22 respectively (see Fig.
        5). On a state-by-state basis, it is important to note the

        Reporting period 13 ‐ 26 May 2017

        KEY MESSAGES
         Influenza activity has increased slightly in the last month, but remains at inter‐seasonal levels across
        Australia.
         Detections of influenza B viruses have increased in recent weeks, consistent with the predominance of
        influenza B viruses worldwide currently.1
         Respiratory viruses other than influenza are more commonly causing influenza‐like illness presentations to
        sentinel general practitioners, with rhinovirus and respiratory syncytial virus (RSV) detected most
        frequently.
         There is no indication of the potential severity of the 2017 season at this time.
         To date, the seasonal influenza vaccines appear to be a good match for circulating virus strains. [ATTACH=CONFIG]n777968[/ATTACH]

          Week 26: 26 June to 2 July, 2017

          Summary:
          • Influenza activity has increased and is likely to continue to rise throughout July.
          • The impact of influenza on the health sector is steadily increasing.
          • 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 continued to increase.
          • Laboratory surveillance – the total number of influenza isolations increased again this week
          with the proportion of respiratory samples positive for influenza higher at 15.5%.
          • Community surveillance – influenza notifications increased in metropolitan local health
          districts (LHD). General Practice ILI activity decreased slightly. Four aged care facilities
          reported respiratory outbreaks.
          • National and international influenza surveillance – influenza activity is increasing in most of
          the southern and central regions of Australia. Activity is sporadic and stable in northern
          parts of the country.
          • 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.

          The influenza season has started and we advise everyone (≥6 months of age) not vaccinated against
          influenza this year to get vaccinated as soon as possible.

          Two hundred and sixty-seven cases of influenza were reported this week with 204 cases being
          characterised as influenza A and 63 as influenza B. Cases comprised of 131 males and 136 females,
          with a median age of 31 years. There have been 2,305 cases of influenza notified year-to-date,
          compared with 890 cases reported for the same period last year

          2017 summary: January to April

          The 2017 influenza season has not begun.
          Although inter-seasonal influenza notification numbers were greater than the five year average for the same period, flu activity is still well below winter influenza levels.
          During this period the majority of notifications were for Influenza A; there were 119 notifications of influenza A (86 per cent) and 19 of Influenza B (14 per cent).

          Report No. 9: Week ending 2 July 2017
          Overview: The 2017 influenza season so far
          Influenza surveillance systems are at average levels. ILI rates are above baseline at average levels.
          The number of notified laboratory confirmed influenza cases for the year to 2 July is 81% higher than at the same
          time in 2016. There has been an increase in notifications in the last couple of weeks for both influenza A and B.
          Most notified cases year-to-date have been type A (78%).
          Twenty swabs were received this week, of which five were positive for influenza; one influenza (H1), two
          Influenza A untyped and two influenza B, but picornavirus is the most commonly detected respiratory virus so
          far in 2017.
          This year we are encouraging GPs to swab all ILI patients (where possible) and ensure all ILI patients are recorded
          on the tally sheet.
          Final stage testing of the new database is now underway, and will hopefully be rolled out in several weeks.

          WEEK ENDING 18TH JUNE 2017

          Summary: There were contradictory changes in indicators this week, with ILI activity decreasing, while
          influenza notifications and non-influenza respiratory virus detections increased.
           Influenza notifications increased to the seasonal threshold level for the first time in 2017. Currently,
          A/H1N1 and A/H3N2 sub-types are co-circulating, with lesser amounts of influenza B virus.
           Influenza percent positivity remains relatively low for this time of year.
           ILI presentations at sentinel GPs and EDs fell this week.
           Influenza-related hospitalisations remain at around average levels for this time of the year, with
          influenza A viruses predominant.
           Non-influenza respiratory virus activity increased, mostly due to an increase in parainfluenza and
          respiratory syncytial virus detections.

          Influenza activity is increasing in most of the southern and central regions of Australia while sporadic and stable in the northern regions of the country.
          While testing for influenza has increased over the reporting fortnight, respiratory viruses other than influenza, in particular rhinovirus, were most commonly detected by sentinel laboratories.
          Nationally, notifications of laboratory confirmed influenza B viruses have continued to increase over the reporting fortnight, however influenza A(H1N1)pdm09 and influenza A(H3N2) are also co-circulating in some parts of the country.
          Influenza-like illness (ILI) in the community was low and relatively stable this reporting fortnight, while ILI presentations to sentinel GPs were also low, but increasing.
          To date, the seasonal influenza vaccines appear to be a good match for circulating virus strains

            The 2017 influenza season has not begun.

            Flu activity during May remained well below winter influenza levels.

            During May the majority of notifications were for Influenza A: there were 29 notifications of influenza A and 7 of Influenza B.

            Surveillance of community influenza-like illness continued to indicate low activity.

            There were 36 notifications of laboratory-confirmed influenza during May 2017 (Table 1). This was higher than the five-year May average (16 notifications) though still within inter-seasonal levels (Figure 1). Residents from the Southern region accounted for the largest proportion of notifications during May (49 per cent).

            participants. Fever, cough and absence from normal duties
            was reported by 1.2% of vaccinated participants and 1.6%
            of unvaccinated participants.

            For participants this week, 14689/23675 (62.0 %) have
            received the seasonal vaccine so far. Of the 4417
            participants who identified as working face-to-face with
            patients, 3542 (80.2%) have received the vaccine.

            Australian influenza report 2017 - Current report:
            Australian Influenza Surveillance Report No 03 - 10 June to 23 June 2017
            Summary
            Influenza activity is increasing in most of the southern and central regions of Australia while sporadic and stable in the northern regions of the country.
            While testing for influenza has increased over the reporting fortnight, respiratory viruses other than influenza, in particular rhinovirus, were most commonly detected by sentinel laboratories.
            Nationally, notifications of laboratory confirmed influenza B viruses have continued to increase over the reporting fortnight, however influenza A(H1N1)pdm09 and influenza A(H3N2) are also co-circulating in some parts of the country.
            Influenza-like illness (ILI) in the community was low and relatively stable this reporting fortnight, while ILI presentations to sentinel GPs were also low, but increasing.
            To date, the seasonal influenza vaccines appear to be a good match for circulating virus strains

              Week 28: 10 to 16 July, 2017
              Summary:
               Surveillance data indicates a continued rise in activity over the last week and it is
              expected to continue to rise throughout July.
               The impact of influenza on the health sector continues to increase.
               Influenza A strains are predominating, particularly the A(H3N2) strain.
              In this reporting week:
               Hospital surveillance ? influenza-like illness (ILI) presentations to selected emergency
              departments continued to increase.
               Laboratory surveillance ? the total number of influenza isolations increased again this week
              with the proportion of respiratory samples positive for influenza higher at 25.4%.
              Influenza A strains were predominant.
               Community surveillance ? influenza notifications increased in metropolitan local health
              districts (LHD). General Practice ILI activity decreased slightly. Eighteen institutions,
              including fifteen aged care facilities, reported influenza outbreaks.
               National and international influenza surveillance ? influenza activity is increasing in the
              majority of Australian jurisdictions, while remaining stable and sporadic in the rural south
              and northern regions of Western Australia, the Northern Territory and the tropical region of
              Queensland.
               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.

              The influenza season has started and we advise everyone (≥6 months of age) not vaccinated against
              influenza this year to get vaccinated as soon as possible.

              Six hundred and eighty eight cases of influenza were reported this week with 572 cases being
              characterised as influenza A and 116 as influenza B. Cases comprised of 303 males and 385
              females, with a median age of 33 years. There have been 3,984 cases of influenza notified year-todate,
              compared with 1,022 cases reported for the same period last year.

              This surveillance report describes influenza activity in Tasmania during May 2017.

              May 2017 update

              The 2017 influenza season has not begun.

              Flu activity during May remained well below winter influenza levels.

              During May the majority of notifications were for Influenza A: there were 29 notifications of influenza A and 7 of Influenza B.

              Surveillance of community influenza-like illness continued to indicate low activity.

              There were 36 notifications of laboratory-confirmed influenza during May 2017 (Table 1). This was higher than the five-year May average (16 notifications) though still within inter-seasonal levels (Figure 1). Residents from the Southern region accounted for the largest proportion of notifications during May (49 per cent).

              Report No. 10: Week ending 9 July 2017
              Overview: The 2017 influenza season so far
              Influenza surveillance systems are at average levels. ILI rates are above baseline at average levels.
              The number of notified laboratory confirmed influenza cases for the year to 9 July is 94% higher than at the same
              time in 2016. The increase in cases to mark the start of the season has occurred earlier this year (late June)
              compared to last year (early August). There has been an increase in notifications in the last couple of weeks for
              both influenza A and B. Most notified cases year-to-date have been type A (70%).
              Sixteen swabs were received this week, of which eight (50%) were positive for influenza (H3), but picornavirus is
              the most commonly detected respiratory virus so far in 2017.
              This year we are encouraging GPs to swab all ILI patients (where possible) and ensure all ILI patients are recorded
              on the tally sheet.
              Final stage testing of the new database is now underway, and will hopefully be rolled out in several weeks.

              Summary: Indicators of ILI and influenza activity, including hospitalisations and laboratory percent positivity,
              increased this week, although levels remain relatively low for this time of the year.
              ? Influenza notifications have remained relatively static just above the seasonal threshold for the past three
              weeks, but these recent data are unreliable, pending correction of an issue with laboratory reporting.
              Currently, A/H1N1 and A/H3N2 sub-types are co-circulating, with lesser amounts of influenza B virus.
              ? Influenza percent positivity increased this week, but remains relatively low for this time of year.
              ? ILI presentations at sentinel GPs increased this week, while ED presentations decreased.
              ? Influenza-related hospitalisations increased sharply this week; primarily attributable to influenza A/H3N2
              virus.
              ? Non-influenza respiratory virus activity increased this week, driven by respiratory syncytial virus.

              REPORTING
              Reports were received from 260 reporters
              from 8 states and territories during the
              reporting period. This includes data from
              GPs reporting to VicSPIN. During weeks 25
              and 26 ASPREN reporters saw a total of
              34,547 patients.

              INFLUENZA-LIKE-ILLNESS (ILI)
              Nationally, ILI notifications increased over the period with 212
              notifications being reported in weeks 25?26. ILI rates
              reported in this period increased to 6 cases per 1000
              consultations (weighted) in week 25 and 8 cases per 1000
              consultations (weighted) for week 26. This was higher than the
              rates seen in the previous fortnight where rates were 5 cases
              per 1000 consultations. For the same reporting period in
              2016, ILI rates were similar at 6 and 7 cases per 1000
              consultations for weeks 25 and 26 respectively (see Fig. 5).
              On a state-by-state basis, it is important to note increasing
              rates in urban NSW, urban and rural Tasmania and rural SA
              (see Fig. 2).

                Week ending 23 July 2017
                Low levels of influenza-like illness activity

                This survey was sent on Monday, 24 July 2017 at 01:13 AM and by 09:00 AM, Thursday 27 July we had received 24616 responses (24390 last week) from 14829 people responding for themselves and 9787 household members across Australia.

                Across Australia, fever and cough was reported by 1.9% of vaccinated participants and 2.5% of unvaccinated participants. Fever, cough and absence from normal duties was reported by 1.4% of vaccinated participants and 1.8% of unvaccinated participants.

                For participants this week, 15285/24616 (62.1 %) have received the seasonal vaccine so far. Of the 4588 participants who identified as working face-to-face with patients, 3677 (80.1%) have received the vaccine.

                Australian influenza report 2017 - Current report:
                Australian Influenza Surveillance Report No 04 - 24 June to 07 July 2017
                Summary
                Influenza activity is increasing in the majority of Australian jurisdictions, while remaining stable and sporadic in the rural south and northern regions of Western Australia, the Northern Territory and the tropical region of Queensland.
                Positive test results for influenza have increased significantly over the reporting fortnight, particularly in Victoria. Respiratory viruses other than influenza, in particular rhinovirus and RSV, were most commonly detected by sentinel laboratories.
                Nationally, notifications of laboratory confirmed influenza B viruses have continued to increase over the reporting fortnight; however the proportion of total notifications has decreased. Influenza A(H1N1)pdm09 and influenza A(H3N2) are also co-circulating in some parts of the country.
                Influenza-like illness (ILI) in the community increased slightly but remained low this reporting fortnight, while ILI presentations to sentinel GPs increased significantly.
                To date, the seasonal influenza vaccines appear to be a good match for circulating virus strains.

                  Week 30: 24 to 30 July, 2017
                  Summary:
                  ? Seasonal influenza activity rose further this week and is nearing its peak.
                  Influenza activity is expected to remain high for the next few weeks
                  ? Influenza A strains are predominating, particularly the A(H3N2) strain.
                  In this reporting week:
                  ? Hospital surveillance ? influenza-like illness (ILI) presentations to selected emergency
                  departments continued to increase. Admissions for pneumonia were also high.
                  ? Laboratory surveillance ? the total number of influenza isolations increased again this week
                  with the proportion of respiratory samples positive for influenza higher at 37.7%.
                  Influenza A strains were predominant.
                  ? Community surveillance ? influenza notifications increased in metropolitan local health
                  districts (LHD) and General Practice ILI activity was increased. Forty-six institutions,
                  including 43 aged care facilities, reported influenza outbreaks.
                  ? National and international influenza surveillance ? influenza activity at the national level
                  continued to increase this reporting fortnight indicating that the season is underway in a
                  majority of regions across Australia.
                  ? 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.

                  The influenza season has started and we advise everyone (≥6 months of age) not vaccinated against
                  influenza this year to get vaccinated as soon as possible

                  Six hundred and forty eight cases of influenza were reported this week with 518 cases being
                  characterised as influenza A and 130 as influenza B. Cases comprised of 285 males and 363
                  females, with a median age of 41 years. There have been 4,633 cases of influenza notified year-todate,
                  compared with 1,109 cases reported for the same period last year.

                  FluTas 2017 Report 3

                  Public Health Services produce the fluTAS Report to provide information about the level of influenza (flu) in Tasmania. Multiple surveillance data sources are used to obtain measures of influenza activity in the community.
                  This surveillance report describes influenza activity in Tasmania during June 2017.

                  June 2017 update

                  The 2017 influenza season has not begun.
                  Overall flu activity at the end of June was still at a pre-seasonal level. However, the number of notifications increased in June.
                  During June the proportion of notifications due to Influenza B increased; there were 35 notifications of influenza A and 28 of Influenza B.
                  Surveillance of community influenza-like illness continued to indicate low activity.
                  Influenza Notifications

                  There were 63 notifications of laboratory-confirmed influenza during June 2017 (Table 1). This was higher than the five-year June average of 39 notifications. Notifications increased during this period. However, at the end of June were still considered at a pre-seasonal level (Figure 1). Residents from the Southern region accounted for the largest proportion of notifications during June (56 per cent).

                  Report No. 12: Week ending 23 July 2017
                  Overview: The 2017 influenza season so far
                  Influenza surveillance systems are at average levels. ILI rates are at average seasonal levels.
                  The number of notified laboratory confirmed influenza cases for the year to 23 July is 147% higher than at the
                  same time in 2016. The increase in cases to mark the start of the season has occurred earlier this year (late June)
                  compared to last year (early August). There has been an increase in notifications in the last few of weeks for both
                  influenza A and B. Most notified cases year-to-date have been type A (78%).
                  Thirty six swabs were received this week, of which three were positive for influenza (H1), fourteen were positive
                  for influenza (H3) and two were positive for influenza B. Influenza is now the most commonly detected
                  respiratory virus from VicSPIN swabs so far this season.
                  This year we are encouraging GPs to swab all ILI patients (where possible) and ensure all ILI patients are recorded
                  on the tally sheet.
                  Final stage testing of the new database is now underway, and will hopefully be rolled out in a couple of weeks

                  WEEK ENDING 23RD JULY 2017
                  KEY POINTS
                  INFLUENZA AND INFLUENZA-LIKE ILLNESSES (ILI)
                  Summary: While the overall trend remains upward, direct indicators of influenza activity, including notifications,
                  hospitalisations and laboratory percent positivity, increased only marginally this week. RSV activity appears to be
                  decreasing.
                   Influenza notifications and percent positivity are gradually trending upwards. Influenza A/H3N2 virus is
                  currently predominant, this week comprising 71% of PathWest detections, followed by A/H1N1 (17%) and
                  influenza B (12%).
                   ILI presentations at sentinel GPs increased sharply this week; conversely, ED presentations decreased.
                   Influenza-related hospitalisations are below average levels for this time of year; primarily attributable to
                  influenza A/H3N2 virus.
                   RSV and overall non-influenza respiratory virus activity has decreased over the past fortnight.

                  SYNDROMIC SURVEILLANCE
                  REPORTING
                  Reports were received from 282 reporters
                  from 8 states and territories during the
                  reporting period. This includes data from
                  GPs reporting to VicSPIN. During weeks 27
                  and 28 ASPREN reporters saw a total of
                  38,914 patients

                  INFLUENZA-LIKE-ILLNESS (ILI)
                  Nationally, ILI notifications increased over the period with 337
                  notifications being reported in weeks 27?28. ILI rates
                  reported in this period increased to 10 cases per 1000
                  consultations (weighted) in week 27 and 8 cases per 1000
                  consultations (weighted) for week 28. This was higher than the
                  rates seen in the previous fortnight where rates were 6 and 8
                  cases per 1000 consultations. For the same reporting period
                  in 2016, ILI rates were similar at 8 cases per 1000
                  consultations for weeks 27 and 28 respectively (see Fig. 5).
                  On a state-by-state basis, it is important to note increasing
                  rates in Remote NSW and rural SA (see Fig. 2).

                  Week ending 30 July 2017
                  Moderate levels of influenza-like illness activity

                  This survey was sent on Monday, 31 July 2017 at 01:13 AM and by 09:00 AM, Thursday 03 August we had received 24682 responses (24805 last week) from 14888 people responding for themselves and 9794 household members across Australia.

                  Across Australia, fever and cough was reported by 2.3% of vaccinated participants and 2.9% of unvaccinated participants. Fever, cough and absence from normal duties was reported by 1.8% of vaccinated participants and 2.0% of unvaccinated participants.

                  For participants this week, 15357/24682 (62.2 %) have received the seasonal vaccine so far. Of the 4614 participants who identified as working face-to-face with patients, 3708 (80.4%) have received the vaccine.

                  Reporting period 8 ? 21 July 2017

                  KEY MESSAGES
                   Influenza activity at the national level continued to increase this reporting fortnight indicating that the
                  season is underway in a majority of regions across Australia. This increase in activity occurred
                  approximately one month earlier than in 2016.
                   Influenza was detected at increasing levels by the majority of sentinel laboratories this reporting fortnight.
                  For the first time since reporting for 2017 began, influenza A was the most common respiratory virus
                  detected by a majority of sentinel laboratories, followed by respiratory syncytial virus (RSV).
                   Influenza A(H3N2) is currently the predominant circulating A subtype in the majority of jurisdictions.
                  Nationally, notifications of laboratory confirmed influenza B viruses reached a plateau this reporting
                  fortnight.
                   Notification rates this year to date have been highest in adults aged 85 years or older, with a secondary
                  peak in young children, aged less than 10 years.
                   Influenza‐like illness (ILI) in the community and ILI presentations to sentinel GPs this fortnight continued
                  the overall increasing trend, however remain within the range of recent seasons.
                   Hospitalisations with confirmed influenza have increased in recent weeks in line with the seasonal increase
                  in community level activity.
                   To date, the seasonal influenza vaccines appear to be a good match for circulating virus strains
                  ...
                  Nationally Notified Influenza Associated Deaths
                  So far in 2017, 27 influenza associated deaths have been notified to the NNDSS. The majority of deaths were
                  due to influenza A (78%, n = 21). The median age of deaths notified was 75 years (range 13 to 97 years). The
                  number of influenza associated deaths reported to the NNDSS is reliant on the follow up of cases to determine
                  the outcome of their infection and most likely does not represent the true mortality associated with this
                  disease.

                    Summary:
                    ? Seasonal influenza activity rose only slightly this week, consistent with the peak of
                    the influenza season. Activity is expected to remain high for the next few weeks.
                    ? Influenza A strains are predominating, but influenza B strains increased.
                    In this reporting week:
                    ? Hospital surveillance ? influenza-like illness (ILI) presentations to selected emergency
                    departments continued to increase. Admissions for pneumonia remain high.
                    ? Laboratory surveillance ? the total number of influenza isolations increased again this week
                    with the proportion of respiratory samples positive for influenza higher at 49.3%.
                    Influenza A strains remain predominant.
                    ? Community surveillance ? influenza notifications increased in all local health districts
                    (LHD), and community ILI indicators were notably increased. Sixty-four institutions,
                    including 58 aged care facilities, reported new influenza outbreaks.
                    ? National and international influenza surveillance ? influenza activity at the national level
                    continued to increase this reporting fortnight with many surveillance systems at levels
                    comparable to the peak of the 2016 season. High levels of influenza activity in the
                    community are likely to continue for the next few weeks.
                    ? 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

                    The number of notified laboratory confirmed influenza cases for the year to 13 August is 160% higher than at the
                    same time in 2016. The increase in cases to mark the start of the season occurred earlier this year (late June)
                    compared to last year (early August), and in the last few weeks the number of notifications has been higher than
                    in the previous year. Most notified cases year-to-date have been type A (80%).
                    Twenty nine swabs were received this week, of which nine were positive for influenza (H3), two were positive for
                    influenza A(H1), two were influenza A untyped and three was positive for influenza B. Influenza is the most
                    commonly detected respiratory virus from VicSPIN swabs so far this season.
                    This year we are encouraging GPs to swab all ILI patients (where possible) and ensure all ILI patients are recorded
                    on the tally sheet.
                    The new database will be rolled out in the next week.

                    KEY POINTS
                    INFLUENZA AND INFLUENZA-LIKE ILLNESSES (ILI)
                    Summary: Seasonal influenza indicators including notifications, percent positivity and hospitalisations remain
                    relatively low for this time of year.
                     Influenza notifications and PathWest laboratory detections declined this week. Influenza A/H3N2 virus is
                    currently predominant, comprising 86% of PathWest detections.
                     ILI presentations at sentinel GPs and EDs increased slightly this week.
                     Influenza-related hospitalisations are below average levels for this time of year; reported hospitalisations
                    are primarily attributable to influenza A/H3N2 virus.
                     While overall non-influenza respiratory virus activity decreased, RSV detections increased this week.

                    SYNDROMIC SURVEILLANCE
                    REPORTING
                    Reports were received from 282 reporters
                    from 8 states and territories during the
                    reporting period. This includes data from
                    GPs reporting to VicSPIN. During weeks 27
                    and 28 ASPREN reporters saw a total of
                    38,914 patients

                    INFLUENZA-LIKE-ILLNESS (ILI)
                    Nationally, ILI notifications increased over the period with 337
                    notifications being reported in weeks 27—28. ILI rates
                    reported in this period increased to 10 cases per 1000
                    consultations (weighted) in week 27 and 8 cases per 1000
                    consultations (weighted) for week 28. This was higher than the
                    rates seen in the previous fortnight where rates were 6 and 8
                    cases per 1000 consultations. For the same reporting period
                    in 2016, ILI rates were similar at 8 cases per 1000
                    consultations for weeks 27 and 28 respectively (see Fig. 5).
                    On a state-by-state basis, it is important to note increasing
                    rates in Remote NSW and rural SA (see Fig. 2).

                    Moderate levels of influenza-like illness activity

                    This survey was sent on Monday, 14 August 2017 at 01:13 AM and by 09:00 AM, Thursday 17 August we had received 25381 responses (25427 last week) from 15180 people responding for themselves and 10201 household members across Australia.

                    Across Australia, fever and cough was reported by 2.9% of vaccinated participants and 4.0% of unvaccinated participants. Fever, cough and absence from normal duties was reported by 2.2% of vaccinated participants and 3.3% of unvaccinated participants.

                    For participants this week, 15760/25381 (62.1 %) have received the seasonal vaccine so far. Of the 4699 participants who identified as working face-to-face with patients, 3791 (80.7%) have received the vaccine.

                    No. 5, 2017
                    Reporting period 8 – 21 July 2017

                    KEY MESSAGES
                     Influenza activity at the national level continued to increase this reporting fortnight indicating that the
                    season is underway in a majority of regions across Australia. This increase in activity occurred
                    approximately one month earlier than in 2016.
                     Influenza was detected at increasing levels by the majority of sentinel laboratories this reporting fortnight.
                    For the first time since reporting for 2017 began, influenza A was the most common respiratory virus
                    detected by a majority of sentinel laboratories, followed by respiratory syncytial virus (RSV).
                     Influenza A(H3N2) is currently the predominant circulating A subtype in the majority of jurisdictions.
                    Nationally, notifications of laboratory confirmed influenza B viruses reached a plateau this reporting
                    fortnight.
                     Notification rates this year to date have been highest in adults aged 85 years or older, with a secondary
                    peak in young children, aged less than 10 years.
                     Influenza‐like illness (ILI) in the community and ILI presentations to sentinel GPs this fortnight continued
                    the overall increasing trend, however remain within the range of recent seasons.
                     Hospitalisations with confirmed influenza have increased in recent weeks in line with the seasonal increase
                    in community level activity.
                     To date, the seasonal influenza vaccines appear to be a good match for circulating virus strains
                    ...
                    Nationally Notified Influenza Associated Deaths
                    So far in 2017, 27 influenza associated deaths have been notified to the NNDSS. The majority of deaths were
                    due to influenza A (78%, n = 21). The median age of deaths notified was 75 years (range 13 to 97 years). The
                    number of influenza associated deaths reported to the NNDSS is reliant on the follow up of cases to determine
                    the outcome of their infection and most likely does not represent the true mortality associated with this
                    disease.

                      Week 33: 14 to 20 August, 2017
                      Summary:
                       Seasonal influenza activity remains high overall, with declines noted in some
                      surveillance indicators. Activity is expected to remain high for the next few weeks.
                       Influenza B activity increased but influenza A strains remained predominant overall.
                      In this reporting week:
                       Hospital surveillance ? influenza-like illness (ILI) presentations to selected emergency
                      departments continued to be high; the index of increase peaked on 11 August.
                       Laboratory surveillance ? the total number of influenza isolations increased again this week
                      with the proportion of respiratory samples positive for influenza slightly higher at 50.5%.
                      The influenza A rate fell slightly while the influenza B rate was increased.
                       Community surveillance ? influenza notifications increased overall but fell in some local
                      health districts (LHD) in Sydney. New influenza outbreaks were reported in 82
                      institutions, including 72 residential aged care facilities.
                       National and international influenza surveillance ? influenza activity at the national level
                      continued to increase this reporting fortnight with many jurisdictions reporting activity at
                      levels comparable to the peak of the 2016 season.
                       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.

                      The influenza season has started and we advise everyone (≥6 months of age) not vaccinated against
                      influenza this year to get vaccinated as soon as possible.

                      One thousand, one hundred and nine cases of influenza were reported this week with 835 cases
                      being characterised as influenza A and 274 as influenza B. Cases comprised of 510 males and 599
                      females, with a median age of 31 years. There have been 7,313 cases of influenza notified year-todate,
                      compared with 1,512 cases reported for the same period last year.

                      The influenza chart shows recent influenza activity in South Australia.

                      FluTas 2017 Report 3

                      Public Health Services produce the fluTAS Report to provide information about the level of influenza (flu) in Tasmania. Multiple surveillance data sources are used to obtain measures of influenza activity in the community.
                      This surveillance report describes influenza activity in Tasmania during June 2017.

                      June 2017 update

                      The 2017 influenza season has not begun.
                      Overall flu activity at the end of June was still at a pre-seasonal level. However, the number of notifications increased in June.
                      During June the proportion of notifications due to Influenza B increased; there were 35 notifications of influenza A and 28 of Influenza B.
                      Surveillance of community influenza-like illness continued to indicate low activity.
                      Influenza Notifications

                      There were 63 notifications of laboratory-confirmed influenza during June 2017 (Table 1). This was higher than the five-year June average of 39 notifications. Notifications increased during this period. However, at the end of June were still considered at a pre-seasonal level (Figure 1). Residents from the Southern region accounted for the largest proportion of notifications during June (56 per cent).

                      Report No. 16: Week ending 20 August 2017
                      Overview: The 2017 influenza season so far
                      Influenza surveillance systems are at average to above average levels.
                      The number of notified laboratory confirmed influenza cases for the year to 20 August is 131% higher than at the
                      same time in 2016. The increase in cases to mark the start of the season occurred earlier this year (late June)
                      compared to last year (early August), and in the last few weeks the number of notifications has been higher than
                      in the previous year. Most notified cases year-to-date have been type A (80%).
                      Fifty four swabs were received this week, of which thirty were positive: thirteen were positive for influenza (H3),
                      one was positive for influenza A(H1), and sixteen were positive for influenza B. Influenza is the most commonly
                      detected respiratory virus from VicSPIN swabs so far this season.
                      This year we are encouraging GPs to swab all ILI patients (where possible) and ensure all ILI patients are recorded
                      on the tally sheet.
                      The new database has been rolled out at www.vicspin.com.au. We have sent login details to all practices and
                      would encourage all GP?s to use the database for data entry. Please contact us with any feedback.

                      KEY POINTS
                      INFLUENZA AND INFLUENZA-LIKE ILLNESSES (ILI)
                      Summary: Influenza notifications and percent positivity increased this week, although levels remain relatively low
                      for this time of year. Hospitalisations remain steady and lower than the seasonal average.
                       ILI presentations at sentinel EDs increased sharply this week, while presentations to sentinel GPs
                      declined.
                       PathWest laboratory detections have plateaued over recent weeks; influenza A/H3N2 virus is currently
                      predominant, comprising 72% of PathWest detections.
                       Influenza-related hospitalisations are below average levels for this time of year; reported hospitalisations
                      are primarily attributable to influenza A/H3N2 virus.
                       Overall non-influenza respiratory virus activity decreased.

                      Australian Influenza Surveillance Report No 06 - 22 July to 04 August 2017
                      Summary
                      Influenza activity at the national level continued to increase this reporting fortnight with many surveillance systems at levels comparable to the peak of the 2016 season.
                      High levels of influenza activity in the community are likely to continue for the next few weeks.
                      There has been almost two and a half times the number of laboratory confirmed notifications of influenza reported to the National Notifiable Diseases Surveillance System this year when compared with the same period last year. An earlier season onset and introduction of rapid testing have contributed, in part, to this increase.
                      Influenza-like illness (ILI) is increasing nationally. Influenza was the most common cause of ILI presentations to sentinel general practitioners this fortnight, with almost half of all patients presenting to sentinel general practitioners with ILI and tested were positive for influenza.
                      Influenza A(H3N2) is currently the predominant circulating virus nationally, however influenza B viruses also continue to circulate.
                      Notification rates this year to date have been highest in adults aged 85 years or older, with a secondary peak in young children, aged 5 to 9 years.
                      Hospitalisations with confirmed influenza have increased overall this reporting fortnight, but have declined in the most recent week.
                      Clinical severity for the season to date, as measured through the proportion of patients admitted directly to ICU and deaths attributed to pneumonia or influenza, is low.
                      To date, based on antigenic characterisation of circulating influenza viruses, the seasonal influenza vaccines appear to be a moderate to good match for circulating virus strains, depending on the strain. Vaccine effectiveness estimates, which provide an indication of how well the vaccine provides protection against influenza, are only available towards the end of the influenza season.
                      ...
                      Nationally Notified Influenza Associated Deaths
                      So far in 2017, 43 influenza associated deaths have been notified to the NNDSS. The majority of deaths were
                      due to influenza A (81%, n = 35). The median age of deaths notified was 81 years (range 13 to 97 years). The
                      number of influenza associated deaths reported to the NNDSS is reliant on the follow up of cases to determine
                      the outcome of their infection and most likely does not represent the true mortality associated with this
                      disease.

                        *New South Wales
                        Week 34: 21 to 27 August, 2017
                        Summary:
                        ? The influenza season has passed its peak but activity remains high. Activity is
                        expected to continue to decline throughout September.
                        ? Influenza A strains remain predominant but are declining. Influenza B activity is steady.
                        In this reporting week:
                        ? Hospital surveillance ? influenza-like illness (ILI) presentations to selected emergency
                        departments decreased for the first time this season. Overall activity remained high.
                        ? Laboratory surveillance ? the total number of influenza isolations decreased for the first
                        time this season, and the influenza-positive test rate was lower at 45.7%. There was a
                        decrease in the proportion of influenza A fell while influenza B was steady.
                        ? Community surveillance ? influenza notifications increased slightly overall but GP and
                        FluTracking surveillance both indicated declines in ILI activity. Influenza outbreaks in
                        institutions declined but there were still 48 outbreaks in residential aged care facilities.
                        ? Deaths with pneumonia or influenza reported on the death certificate ? the NSW Registry of
                        Births, Deaths, and Marriages has recorded 69 deaths in association with influenza in 2017.
                        The rate of deaths classified as ?pneumonia and influenza? was increased overall.

                        ? National and international influenza surveillance ? influenza activity at the national level
                        continued to increase this reporting fortnight with most jurisdictions reporting peak
                        seasonal activity levels, with notifications above the usual range.
                        ? 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.

                        20 August to 26 August 2017
                        The influenza season is underway but it is not too late to be vaccinated. We advise everyone (≥6
                        months of age) not vaccinated against influenza this year to get vaccinated as soon as possible.

                        One thousand, five hundred and thirty five cases of influenza were reported this week with 1,042
                        cases being characterised as influenza A and 493 as influenza B. Cases comprised of 705 males and
                        828 females, with a median age of 32 years. There have been 10,361 cases of influenza notified
                        year-to-date, compared with 2,149 cases reported for the same period last year. Influenza
                        notifications are higher than currently reported as not all influenza notifications have been entered into
                        the surveillance system

                        fluTAS 2017 Report 4

                        July 2017 update

                        The 2017 influenza season commenced at the end of June.
                        July was a period of increasing seasonal flu activity, being driven by both Influenza A (188 notifications) and Influenza B (131 notifications). Influenza A(H3N2) remains the most commonly detected subtype.
                        During July, influenza hospital admissions increased. Community influenza-like illness surveillance indicated low to early seasonal activity.
                        To date the 2017 influenza vaccine is a good match for circulating virus strains in Australia.

                        There were 319 notifications of laboratory-confirmed influenza during July 2017 (Table 1). This was greater than June 2017 (63 notifications) and the five-year July average of 184 notifications. Notifications since the start of 2017 indicate that the winter influenza season commenced in Tasmania towards the end of June, with July being a period of increasing seasonal activity. The commencement of the 2017 season is approximately one-month earlier than recent seasons (Figure 1).

                        There have been a total of 557 influenza notifications since the start of 2017.

                        Report No. 17: Week ending 27 August 2017
                        Overview: The 2017 influenza season so far
                        Influenza surveillance systems are at average to above average levels.
                        The number of notified laboratory confirmed influenza cases for the year to 27 August is higher than at the same
                        time in 2016. The increase in cases to mark the start of the season occurred earlier this year (late June) compared
                        to last year (early August), and in the last few weeks the number of notifications has been higher than in the
                        previous year. Most notified cases year-to-date have been type A (80%).
                        Fifty two swabs were received this week, of which nine were positive for influenza (H3), ten were positive for
                        influenza A(untyped), and seven were positive for influenza B. Influenza is the most commonly detected
                        respiratory virus from VicSPIN swabs so far this season.
                        This year we are encouraging GPs to swab all ILI patients (where possible) and ensure all ILI patients are recorded
                        on the tally sheet.
                        The new database has been rolled out at www.vicspin.com.au. We have sent login details to all practices and
                        would encourage all GP?s to use the database for data entry. Please contact us with any feedback.

                        WEEK ENDING 20TH AUGUST 2017
                        KEY POINTS
                        INFLUENZA AND INFLUENZA-LIKE ILLNESSES (ILI)
                        Summary: Influenza notifications and percent positivity are gradually trending upwards, although levels remain
                        relatively low for this time of year. Hospitalisations with influenza remain lower than the average of recent
                        seasons.
                         ILI presentations at sentinel GPs increased slightly this week, while presentations to sentinel EDs fell
                        after experiencing a sharp increase last week.
                         PathWest laboratory detections have increased gradually over recent weeks. Influenza A/H3N2 virus
                        remains predominant, comprising 59% of PathWest detections, but influenza A/H1N1 detections
                        increased this week (25%) and influenza B remains relatively steady (16%).
                         Influenza-related hospitalisations are below average levels for this time of year; and are primarily
                        attributable to influenza A/H3N2 virus.
                         RSV and overall non-influenza respiratory virus activity continues to decrease.

                        SYNDROMIC SURVEILLANCE
                        REPORTING
                        Reports were received from 282 reporters
                        from 8 states and territories during the
                        reporting period. This includes data from
                        GPs reporting to VicSPIN. During weeks 27
                        and 28 ASPREN reporters saw a total of
                        38,914 patients

                        INFLUENZA-LIKE-ILLNESS (ILI)
                        Nationally, ILI notifications increased over the period with 337
                        notifications being reported in weeks 27—28. ILI rates
                        reported in this period increased to 10 cases per 1000
                        consultations (weighted) in week 27 and 8 cases per 1000
                        consultations (weighted) for week 28. This was higher than the
                        rates seen in the previous fortnight where rates were 6 and 8
                        cases per 1000 consultations. For the same reporting period
                        in 2016, ILI rates were similar at 8 cases per 1000
                        consultations for weeks 27 and 28 respectively (see Fig. 5).
                        On a state-by-state basis, it is important to note increasing
                        rates in Remote NSW and rural SA (see Fig. 2).

                        Moderate levels of influenza-like illness activity

                        This survey was sent on Monday, 28 August 2017 at 01:13 AM and by 09:00 AM, Thursday 31 August we had received 25319 responses (25701 last week) from 15144 people responding for themselves and 10175 household members across Australia.

                        Across Australia, fever and cough was reported by 2.8% of vaccinated participants and 3.7% of unvaccinated participants. Fever, cough and absence from normal duties was reported by 2.3% of vaccinated participants and 3.0% of unvaccinated participants.

                        For participants this week, 15819/25319 (62.5 %) have received the seasonal vaccine so far. Of the 4666 participants who identified as working face-to-face with patients, 3784 (81.1%) have received the vaccine.

                        AUSTRALIAN INFLUENZA
                        SURVEILLANCE REPORT
                        No. 7, 2017
                        5 ? 18 August 2017
                        The Department of Health acknowledges the providers of the many sources of data used in this report and
                        greatly appreciates their contribution.
                        KEY MESSAGES
                         Influenza activity at the national level continued to increase this reporting fortnight with many
                        surveillance systems at levels comparable to or exceeding the peak of the 2016 season.
                         High levels of influenza activity in the community are likely to continue for the next few weeks.
                        There has been almost two and a half times the number of laboratory confirmed notifications of influenza
                        reported to the National Notifiable Diseases Surveillance System this year when compared with the same
                        period last year. An earlier season onset and introduction of rapid testing have contributed, in part, to this
                        increase.

                         Influenza‐like illness (ILI) is increasing nationally. Influenza was the most common cause of ILI
                        presentations to sentinel general practitioners this fortnight, with more than half of all patients presenting
                        to sentinel general practitioners with ILI and tested were positive for influenza.
                         Influenza A(H3N2) is currently the predominant circulating influenza A virus nationally, though the number
                        of notifications has decreased this reporting period. Influenza B viruses also continue to circulate.
                         Notification rates this year to date have been highest in adults aged 80 years or older, with a secondary
                        peak in young children, aged 5 to 9 years.
                         Hospitalisations with confirmed influenza have increased overall this reporting fortnight, but have
                        declined in the most recent week.
                         Clinical severity for the season to date, as measured through the proportion of patients admitted directly
                        to ICU and deaths attributed to pneumonia or influenza, is low.
                         To date, based on antigenic characterisation of circulating influenza viruses, the seasonal influenza
                        vaccines appear to be a moderate to good match for circulating virus strains, depending on the strain.
                        Vaccine effectiveness estimates, which provide an indication of how well the vaccine provides protection
                        against influenza, are only available towards the end of the influenza season.
                        ...
                        Nationally Notified Influenza Associated Deaths
                        So far in 2017, 52 influenza associated deaths have been notified to the NNDSS. The majority of deaths were
                        due to influenza A (81%, n = 43). The median age of deaths notified was 81 years (range 13 to 97 years). The
                        number of influenza associated deaths reported to the NNDSS is reliant on the follow up of cases to determine
                        the outcome of their infection and most likely does not represent the true mortality associated with this
                        disease.
