    PHE Weekly National Influenza Report
    Summary of UK surveillance of influenza and other seasonal
    respiratory illnesses
    25 February 2016 – Week 08 report (up to week 07 data)

    Summary
    In week 07 2016 (ending 21 February 2016), influenza circulation with mainly A(H1N1)pdm09 continues with indicators starting
    to stabilise across surveillance schemes, including the number of respiratory outbreaks, GP ILI consultation rates, the
    proportion of laboratory samples positive for influenza and influenza admissions to ICU. Updated guidance on antiviral
    prescribing in secondary care when influenza A(H1N1)pdm09 is the dominant circulating strain has been published.
     Community influenza surveillance
    o During week 07, selected respiratory indicators, including GP influenza-like consultations remained stable, while other
    respiratory indicators including upper and lower respiratory tract infections continued to decrease.
    o Seventeen new acute respiratory outbreaks have been reported in the past 7 days. Two outbreaks were in schools where one
    tested positive for influenza A(H1N1)pdm09. Seven outbreaks were from care homes where two tested positive for influenza
    A(H1N1)pdm09. Four outbreaks were from hospitals where one tested positive for influenza A(not subtyped) and one tested
    positive for a mixed infection with influenza A(not subtyped) and influenza B. The remaining four outbreaks were from other
    settings where two tested positive for influenza A(not subtyped and one tested positive for a mixed infection of influenza
    A(untyped) and influenza B.
     Overall weekly influenza GP consultation rates across the UK
    o In week 07, overall weekly influenza-like illness (ILI) GP consultation rate has decreased but remains above the baseline
    threshold in England (17.3 per 100,000). ILI rates have slightly increased or remained similar in Scotland (28.6 per 100,000) and
    Wales (12.1 per 100,000) and a decrease was noted in in Northern Ireland (24.5 per 100,000)
    o Through the GP In Hours surveillance system, weekly ILI rates have remained stable and within seasonally expected levels in
    week 07.
     Influenza-confirmed hospitalisations
    o One hundred and thirty-one new admissions to ICU/HDU with confirmed influenza (fifty-five influenza A(H1N1)pdm09,seventyfour
    influenza A(unknown subtype) and two influenza A(H3N2)) were reported through the USISS mandatory ICU/HDU
    surveillance scheme across the UK (119 NHS Trusts in England) in week 07, a rate of 0.32 per 100,000, compared to 0.31 in
    week 06. Ten new confirmed influenza deaths were also reported through this scheme.
    o One hundred and twenty-nine new hospitalised confirmed influenza cases (one hundred influenza A(H1N1)pdm09, twenty-one
    influenza A(unknown subtype), one influenza A(H3N2) and seven influenza B) were reported through the USISS sentinel
    hospital network across England (20 NHS Trusts), a rate of 1.68 compared to 1.40 per 100,000 the previous week.
    o Since week 40, thirty-seven confirmed influenza admissions have been reported (twenty-nine influenza A(H1N1)pdm09, seven
    influenza A(unknown subtype) and one influenza B) from the six Severe Respiratory Failure centres in the UK.
     All-cause mortality data
    o Up to week 07 2016 in England, excess mortality by date of death has been seen in 15-64 year olds in weeks 52-03 and 05-
    07; and in <5 year olds and 5-14 year olds in week 51 with the EuroMoMo algorithm. In the devolved administrations,
    significant excess was seen in Scotland (0-4 year olds).
     Microbiological surveillance
    o Fifty-four samples tested positive for influenza (42 influenza A(H1N1)pdm09, 6 influenza A(untyped) and 6 influenza B)
    through GP sentinel schemes across the UK, with an overall positivity of 33.3%.
    o Four hundred and four influenza positive detections were recorded through the DataMart scheme (two hundred and sixty-two
    A(H1N1)pdm09, four A(H3), one hundred and one A(not subtyped) and thirty-seven influenza B). A positivity of 22.6% was
    seen in week 07, compared to 20.7% in week 06, with the highest positivity in 15-44 year olds (31.8%). This is above the allage
    threshold for 2015/16 season of 7.4%.
     Vaccination
    o Up to week 04 2016 in 98.8% GP practices reporting weekly to Immform, the provisional proportion of people in England who
    had received the 2015/16 influenza vaccine in targeted groups was as follows: 45.1% in under 65 years in a clinical risk group,

    published. The report provides uptake at national, area team and CCG level.
     International situation
    o Globally, increasing levels of influenza activity continued to be reported in the temperate zones of the northern hemisphere
    with influenza A(H1N1)pdm09 as the most detected virus.
    ...
    - In week 07, one hundred and thirty-one new admissions to ICU/HDU with confirmed influenza (55 influenza

        circulation increasing. Updated guidance on antiviral prescribing in secondary care when influenza A(H1N1)pdm09 is the
        dominant circulating strain has been published.

         Community influenza surveillance
        o During week 09, GP influenza-like consultations reported through the syndomic surveillance system, remained stable.
        Sixteen new acute respiratory outbreaks have been reported in the past 7 days. Eleven outbreaks were in schools with no test
        results available. One outbreak was from a hospital which tested positive for influenza A(not subtyped). The sixteenth outbreak
        was from another setting (nursery) where the test result was not available.
         Overall weekly influenza GP consultation rates across the UK
        o In week 09, overall weekly influenza-like illness (ILI) GP consultation rate is similar and remains above the baseline threshold in
        England (23.8 per 100,000). In the devolved administrations, ILI rate for Scotland (20.1 per 100,000) and Northern Ireland (36.1
        per 100,000) remained similar. An increase in the ILI rate for Wales was seen (24.2 per 100,000).

        proportion of children in England who received the 2015/16 live attenuated intranasal vaccine (LAIV) from 1 September 2015
        to 31 January 2016 was as follows: 53.6% in children school year 1 age (5-6 years) and 52.1% in children school year 2 age
        (6-7 years).
        o WHO have published their recommendations for the composition of the 2016/17 northern hemisphere influenza vaccine.
         International situation
        o Globally, high levels of influenza activity continued to be reported in the Northern Hemisphere with influenza
        A(H1N1)pdm09 as the most detected virus and an increase in the proportion of influenza B viruses has been noted.
        ...

        - In week 09, one hundred and fifty-five new admissions to ICU/HDU with confirmed influenza (70 influenza A(H1N1)pdm09, 68 influenza A(unknown subtype), 1 influenza A(H3N2) and 16 influenza B) were reported across the UK (137/156 Trusts in England) through the USISS mandatory ICU scheme (Figures 6 and 7), a rate of 0.34 per 100,000, compared to 0.33 per 100,000 in the previous week. Twenty-four new confirmed influenza deaths were also reported in week 09 2016. A total of 1,426 admissions (680 influenza A(H1N1)pdm09, 23 influenza A(H3N2), 661 influenza A (unknown subtype) and 62 influenza B) and 127 confirmed influenza deaths have been reported since week 40 2015.

        ...
        -In week 08 2016, an estimated 11,056 all-cause deaths were
        registered in England and Wales (source: Office for National
        Statistics). This is an increase compared to the 10,590
        estimated death registrations in week 07 2016, and is below the
        95% upper limit of expected death registrations for the time of
        year as calculated by PHE (Figure 9). The sharp drop in the
        number of deaths in week 53 corresponds to a week where
        there were bank holidays and fewer days when deaths were
        registered. Therefore this drop is likely to be artificial.

            PHE Weekly National Influenza Report
            Summary of UK surveillance of influenza and other seasonal
            respiratory illnesses
            24 March 2016 – Week 12 report (up to week 11 data)
            https://www.gov.uk/government/upload..._24Mar2016.pdf

            Summary

            In week 11 2016 (ending 20 March 2016), influenza circulation with mainly A(H1N1)pdm09 continues with indicators stable
            across surveillance schemes, including the number of influenza admissions to hospital and ICU. A further increase in influenza
            B circulation has been noted in several surveillance schemes, this week. Updated guidance on antiviral prescribing in
            secondary care when influenza A(H1N1)pdm09 is the dominant circulating strain has been published.

             Community influenza surveillance
            o During week 11, GP influenza-like consultations for influenza-like illness reported through the syndromic surveillance system
            continued to increase.
            o Seventy-seven new acute respiratory outbreaks have been reported in the past 7 days. 49 outbreaks were from schools where
            one tested positive for influenza A(not subtyped) and two tested positive for influenza B. 8 outbreaks were from hospitals, where
            one tested positive for influenza A(not subtyped), three for influenza B and two influenza A(H1N1)pdm09. 15 outbreaks were
            from care homes where five tested positive for influenza A(H1N1)pdm09, three for influenza A(not subtyped) and two influenza
            B. The remaining 5 outbreaks were from other settings such as nurseries and prisons, where one tested positive for influenza
            A(not subtyped).
             Overall weekly influenza GP consultation rates across the UK
            o In week 11, overall weekly influenza-like illness (ILI) GP consultation rate has increased and is now above the medium intensity
            threshold in England (28.7 per 100,000). In the devolved administrations, the ILI rate for Scotland (27.9 per 100,000) decreased
            slightly, whereas a slight increase was noted in the ILI rate for Northern Ireland (33.5 per 100,000) and the ILI rate for Wales
            (21.9 per 100,000) remained similar to last week.
            o Through the GP In Hours surveillance system, weekly ILI rates have increased and are above baseline levels in week 11.
             Influenza-confirmed hospitalisations
            o One hundred and sixty-three new admissions to ICU/HDU with confirmed influenza (sixty influenza A(H1N1)pdm09, seventythree
            influenza A(unknown subtype), five influenza A(H3N2) and twenty-five influenza B) were reported through the USISS
            mandatory ICU/HDU surveillance scheme across the UK (129 NHS Trusts in England) in week 11, a rate of 0.33 per 100,000,
            compared to 0.34 per 100,000 in week 10. Twelve new confirmed influenza deaths were also reported through this scheme.
            o One hundred and sixty new hospitalised confirmed influenza cases (eighty-four influenza A(H1N1)pdm09, twenty-two influenza
            A(unknown subtype) and fifty-four influenza B) were reported through the USISS sentinel hospital network across England (18
            NHS Trusts), a rate of 1.87 per 100,000 compared to 2.22 per 100,000 the previous week.
            o Since week 40, sixty-four confirmed influenza admissions have been reported (fifty-six influenza A(H1N1)pdm09, six influenza
            A(unknown subtype) and two influenza B) from the six Severe Respiratory Failure centres in the UK.
             All-cause mortality data
            o Up to week 11 2016 in England, excess mortality by date of death has been seen in 15-64 year olds from week 52 to 03, 04 to
            07 and 09 to 11; in <5 year olds in weeks 51 and 05, and 5-14 year olds in week 51 with the EuroMoMo algorithm. In the
            devolved administrations, significant excess was seen in Northern Ireland (15-64 year olds) in week 11 2016.
             Microbiological surveillance

            and 40 influenza B) through GP sentinel schemes across the UK, with an overall positivity of 46.4%, compared to 46.3% in
            previous week.
            o Four hundred and fifty-seven influenza positive detections were recorded through the DataMart scheme (one hundred and
            ninety-five A(H1N1)pdm09, thirteen A(H3), eighty-three A(not subtyped) and one hundred and sixty-six influenza B). A
            positivity of 25.7% was seen in week 11, compared to 26.7% in week 10, with the highest positivity in 15-44 year olds (33.3%).

            Comment: I'm not sure what is happening to the fatality totals these past two weeks. Often the total fatalities given is greater than the sum of the previous week and the additional confirmed in the current week. I assume that this is because late confirmations of fatalities from earlier in the season get added to the total. But the past two weeks the numbers just don't add up. Week 10 reported a total of 127 deaths. Week 11 added 15 deaths, but only raised the total to 139, an increase of 12. Week 12 added 12 new deaths, but did not raise the total at all. - Ro

              PHE Weekly National Influenza Report
              Summary of UK surveillance of influenza and other seasonal
              respiratory illnesses
              31 March 2016 – Week 13 report (up to week 12 data)
              https://www.gov.uk/government/upload..._31Mar2016.pdf

              Summary
              In week 12 2016 (ending 27 March 2016), allowing for Easter reporting breaks, influenza activity continues with influenza
              A(H1N1)pdm09 and influenza B co-circulating at present with elevated indicators across surveillance schemes, including the
              number of influenza hospital and ICU admissions. Updated guidance on antiviral prescribing in secondary care when influenza
              A(H1N1)pdm09 is the dominant circulating strain has been published.
               Community influenza surveillance
              o During week 12, GP influenza-like consultations for influenza-like illness reported through the syndromic surveillance system
              remain above baseline levels.
              o Thirty new acute respiratory outbreaks have been reported in the past 7 days. 11 outbreaks were from schools where one
              tested positive for influenza A(H1N1)pdm09. 8 outbreaks were from hospitals, where four tested positive for influenza A(not
              subtyped), one for influenza B and two influenza A(H1N1)pdm09. 11 outbreaks were from care homes where three tested
              positive for influenza A(not subtyped) and two influenza B.
               Overall weekly influenza GP consultation rates across the UK
              o Due to the bank holiday in week 12 (ending 27 March 2016), GP surgeries were only open for four days – data should therefore
              be interpreted with caution.
              o In week 12, overall weekly influenza-like illness (ILI) GP consultation rate has decreased, but remains above the baseline
              threshold in England (24.4 per 100,000). In the devolved administrations, the ILI rate for Scotland (30.8 per 100,000) has
              increased, whereas ILI rates for Northern Ireland (33.7 per 100,000) and Wales (20.4 per 100,000) remained similar to last
              week.
              o Through the GP In Hours surveillance system, weekly ILI rates remain above baseline levels in week 12.
               Influenza-confirmed hospitalisations
              o One hundred and thirty-four new admissions to ICU/HDU with confirmed influenza (fifty-one influenza A(H1N1)pdm09, forty-one
              influenza A(unknown subtype), four influenza A(H3N2) and thirty-eight influenza B) were reported through the USISS mandatory
              ICU/HDU surveillance scheme across the UK (122 NHS Trusts in England) in week 12, a rate of 0.34 per 100,000, compared to
              0.36 per 100,000 in week 11. Seven new confirmed influenza deaths were also reported through this scheme.
              o Two hundred and twelve new hospitalised confirmed influenza cases (sixty-two influenza A(H1N1)pdm09, thirty-one influenza
              A(unknown subtype), one influenza A(H3N2) and one hundred and eighteen influenza B) were reported through the USISS
              sentinel hospital network across England (18 NHS Trusts), a rate of 2.84 per 100,000 in week 12 compared to 2.06 per 100,000
              the previous week.
              o Since week 40, sixty-four confirmed influenza admissions have been reported (fifty-six influenza A(H1N1)pdm09, six influenza
              A(unknown subtype) and two influenza B) from the six Severe Respiratory Failure centres in the UK.
               All-cause mortality data
              o Up to week 12 2016 in England, excess mortality by date of death has been seen in 15-64 year olds from week 52 to 03, 05 to
              07 and 09 to 12; in <5 year olds in weeks 51 and 05, and 5-14 year olds in week 51 with the EuroMoMo algorithm. In the
              devolved administrations, significant excess was seen in Northern Ireland (15-64 year olds) in week 12 2016.
               Microbiological surveillance
              o Sixty-three samples tested positive for influenza (26 influenza A(H1N1)pdm09, 5 influenza A(untyped) and 32 influenza B)
              through GP sentinel schemes across the UK, with an overall positivity of 44.1%, compared to 46.4% in the previous week.

                o In week 13, overall weekly influenza-like illness (ILI) GP consultation rate has decreased, but remains above the baseline
                threshold in England (21.8 per 100,000). In the devolved administrations, the ILI rates for Scotland (21.8 per 100,000), Wales
                (19.1 per 100,000) and Northern Ireland (10.0 per 100,000) have decreased in week 13.
                o Through the GP In Hours surveillance system, weekly ILI rates remain above baseline levels in week 12.
                 Influenza-confirmed hospitalisations
                o One hundred and twenty-five new admissions to ICU/HDU with confirmed influenza (forty-five influenza A(H1N1)pdm09, thirtynine
                influenza A(unknown subtype), four influenza A(H3N2) and thirty-seven influenza B) were reported through the USISS
                mandatory ICU/HDU surveillance scheme across the UK (122 NHS Trusts in England) in week 13, a rate of 0.27 per 100,000,
                compared to 0.32 per 100,000 in week 12. Eleven new confirmed influenza deaths were also reported through this scheme.
                o One hundred and thirty-four new hospitalised confirmed influenza cases (forty-two influenza A(H1N1)pdm09, seventeen
                influenza A(unknown subtype) and seventy-five influenza B) were reported through the USISS sentinel hospital network across
                England (18 NHS Trusts), a rate of 1.75 per 100,000 in week 13 compared to 2.75 per 100,000 the previous week.
                o Since week 40, sixty-seven confirmed influenza admissions have been reported (fifty-nine influenza A(H1N1)pdm09, six
                influenza A(unknown subtype) and two influenza B) from the six Severe Respiratory Failure centres in the UK.
                 All-cause mortality data
                o Up to week 13 2016 in England, excess mortality by date of death has been seen in 15-64 year olds from week 52 to 03, 05 to
                07, 09 to 10 and 12 to 13; in <5 year olds in weeks 51 and 05, and 5-14 year olds in week 51 with the EuroMoMo algorithm. In
                the devolved administrations, significant excess was seen only in Northern Ireland (15-64 year olds) in week 13 2016.
                 Microbiological surveillance
                o Thirty samples tested positive for influenza (7 influenza A(H1N1)pdm09, 1 influenza A(untyped), 3 influenza A(H3N2) and 19
                influenza B) through GP sentinel schemes across the UK, with an overall positivity of 35.3%, compared to 44.1% in the
                previous week.
                o Four hundred and eighteen influenza positive detections were recorded through the DataMart scheme (one hundred and
                twenty-four A(H1N1)pdm09, seven A(H3), thirty-five A(not subtyped) and two hundred and fifty-two influenza B). A positivity of
                23.0% was seen in week 13, compared to 28.1% in week 12, with the highest positivity in 15-44 year olds (29.3%). This is
                above the all-age threshold for 2015/16 season of 7.4%.
                 Vaccination
                o Up to week 04 2016 (31 January 2016) in 98.8% GP practices reporting weekly to Immform, the provisional proportion of
                people in England who had received the 2015/16 influenza vaccine in targeted groups was as follows: 45.1% in under 65
                years in a clinical risk group, 42.3% in pregnant women, 71.0% in 65+ year olds, 35.4% in all 2 year olds, 37.7% in all 3 year

                  Number of deaths in England and Wales hits 12-year high
                  Public Health England says less effective flu vaccine may have contributed to largest percentage rise in deaths since 1968

                  The failure to provide an effective flu vaccine last year may have contributed to the largest rise in deaths in England and Wales for 12 years, the government’s public health agency has admitted.

                  An additional 28,189 people died in 2015 compared with 2014, the largest percentage increase since 1968, according to figures published by the Office for National Statistics. The majority (24,201) of the excess deaths were people aged 75 and over, many of whom died from flu or dementia.

                  The flu vaccine issued last winter only provided low protection against the main strain of the virus then affecting the UK, Public Health England (PHE) said.

                      PHE Weekly National Influenza Report
                      Summary of UK surveillance of influenza and other seasonal
                      respiratory illnesses
                      21 April 2016 – Week 16 report (up to week 15 data)

                      Summary
                      In week 15 2016 (ending 17 April 2016), influenza activity continues to decrease but remains above baseline levels across
                      surveillance schemes. Updated guidance on antiviral prescribing in secondary care when influenza A(H1N1)pdm09 is the
                      dominant circulating strain has been published.
                       Community influenza surveillance
                      o During week 15, there were continued decreases in a range of respiratory indicators across syndromic surveillance systems.
                      o Eleven new acute respiratory outbreaks have been reported in the past 7 days. 2 outbreaks were from schools where one
                      tested positive for influenza A(not subtyped). 4 outbreaks were from hospitals, where 2 tested positive for influenza A(not
                      subtyped), 1 for influenza A(H1N1)pdm09 and 1 for influenza B. 3 outbreaks were from care homes where one tested positive
                      for influenza A(not subtyped). The remaining outbreak was from another setting, a nursery, where no test results were available.
                       Overall weekly influenza GP consultation rates across the UK
                      o In week 15, overall weekly influenza-like illness (ILI) GP consultation rate has decreased further, but remains above the baseline
                      threshold in England (15.7 per 100,000). In the devolved administrations, the ILI rates for Scotland (13.5 per 100,000), Northern
                      Ireland (14.0 per 100,000) and Wales (4.4 per 100,000) have decreased in week 15.
                      o Through the GP In Hours surveillance system, GP consulations for ILI have continued to decrease across all age groups and
                      regions and are starting to approach seasonally expected levels.
                       Influenza-confirmed hospitalisations
                      o Sixty-eight new admissions to ICU/HDU with confirmed influenza (17 influenza A(H1N1)pdm09, 13 influenza A(unknown
                      subtype) and 38 influenza B) were reported through the USISS mandatory ICU/HDU surveillance scheme across the UK (128
                      NHS Trusts in England) in week 15, a rate of 0.16 per 100,000, compared to 0.23 per 100,000 in week 14. Three new confirmed
                      influenza deaths were also reported through this scheme.
                      o Fifty-seven new hospitalised confirmed influenza cases (13 influenza A(H1N1)pdm09, 8 influenza A(unknown subtype) and 36
                      influenza B) were reported through the USISS sentinel hospital network across England (20 NHS Trusts), a rate of 0.71 per
                      100,000 in week 15 compared to 1.65 per 100,000 the previous week.
                      o Since week 40, seventy-two confirmed influenza admissions have been reported (63 influenza A(H1N1)pdm09, 6 influenza
                      A(unknown subtype) and 3 influenza B) from the six Severe Respiratory Failure centres in the UK.
                       All-cause mortality data
                      o Up to week 15 2016 in England, excess mortality by date of death was seen in 15-64 year olds from week 52 to 03, 05 to 07,
                      09 to 10; in <5 year olds in weeks 40,51 and 05, and 5-14 year olds in week 51 with the EuroMoMo algorithm. In the devolved
                      administrations, no significant excess was seen in week 15 2016.
                       Microbiological surveillance
                      o Seventeen samples tested positive for influenza (2 influenza A(H1N1)pdm09 and 15 influenza B) through GP sentinel
                      schemes across the UK, with an overall positivity of 23.0%, compared to 35.0% in the previous week.
                      o Two hundred and nine influenza positive detections were recorded through the DataMart scheme (51 A(H1N1)pdm09, 11
                      A(H3), 19 A(not subtyped) and 128 influenza B). A positivity of 13.6% was seen in week 15, compared to 18.4% in week 14,
                      with the highest positivity in 15-44 year olds (17.2%). This is above the all-age threshold for 2015/16 season of 7.4%.

                        PHE Weekly National Influenza Report
                        Summary of UK surveillance of influenza and other seasonal
                        respiratory illnesses
                        28 April 2016 – Week 17 report (up to week 16 data)
                        https://www.gov.uk/government/upload...ek_17_2016.pdf

                        Summary
                        In week 16 2016 (ending 24 April 2016), influenza activity continues to decrease and has reached or nearing the expected
                        baseline levels across surveillance schemes. Updated guidance on antiviral prescribing in secondary care when influenza
                        A(H1N1)pdm09 is the dominant circulating strain has been published.
                         Community influenza surveillance
                        o During week 16, there were continued decreases in a range of respiratory indicators across all syndromic surveillance systems,
                        with influenza activity now at seasonally expected levels.
                        o Nine new acute respiratory outbreaks have been reported in the past 7 days. 2 outbreaks were from schools where no test
                        results were available. 1 outbreak was reported from a hospital which tested positive for influenza A(H1N1)pdm09. 5 outbreaks
                        were from care homes where 2 tested positive for influenza A(not subtyped). The remaining outbreak was from the other
                        settings category (an intermediate care centre) where no test results were available.
                         Overall weekly influenza GP consultation rates across the UK
                        o In week 16, overall weekly influenza-like illness (ILI) GP consultation rate has decreased further, and is now below the baseline
                        threshold in England (8.6 per 100,000). In the devolved administrations, the ILI rate for Scotland has decreased (7.6 per
                        100,000), whereas the ILI rates for Wales (6.7 per 100,000) and Northern Ireland (15.6 per 100,000) have remained similar to
                        the previous week.
                        o Through the GP In Hours surveillance system, GP consulations for ILI have continued to decrease across all age groups and
                        regions and at seasonally expected levels.
                         Influenza-confirmed hospitalisations
                        o Twenty-nine new admissions to ICU/HDU with confirmed influenza (4 influenza A(H1N1)pdm09, 9 influenza A(unknown
                        subtype) and 16 influenza B) were reported through the USISS mandatory ICU/HDU surveillance scheme across the UK (138
                        NHS Trusts in England) in week 16, a rate of 0.07 per 100,000, compared to 0.14 per 100,000 in week 15. Two new confirmed
                        influenza deaths were also reported through this scheme.
                        o Forty-five new hospitalised confirmed influenza cases (3 influenza A(H1N1)pdm09, 3 influenza A(unknown subtype) and 39
                        influenza B) were reported through the USISS sentinel hospital network across England (21 NHS Trusts), a rate of 0.54 per
                        100,000 in week 16 compared to 0.78 per 100,000 the previous week.
                        o Since week 40, seventy-three confirmed influenza admissions have been reported (63 influenza A(H1N1)pdm09, 6 influenza
                        A(unknown subtype) and 4 influenza B) from the six Severe Respiratory Failure centres in the UK.
                         All-cause mortality data
                        o Up to week 16 2016 in England, excess mortality by date of death was seen in 15-64 year olds from week 52 to 03, 05 to 07,
                        09 to 10 and <5 year olds in weeks 40 and 05 with the EuroMoMo algorithm. In the devolved administrations, no significant
                        excess was seen in week 16 2016.
                         Microbiological surveillance
                        o Fourteen samples tested positive for influenza (2 influenza A(untyped), 1 influenza A(H3N2) and 11 influenza B) through GP
                        sentinel schemes across the UK, with an overall positivity of 20.9%, compared to 24.3% in the previous week.
                        o One hundred and twenty-seven influenza positive detections were recorded through the DataMart scheme (15
                        A(H1N1)pdm09, 5 A(H3), 14 A(not subtyped) and 93 influenza B). A positivity of 9.9% was seen in week 16, compared to
                        13.0% in week 15, with the highest positivity in 15-44 year olds (14.0%). This is above the all-age threshold for 2015/16
                        season of 7.4%.
