    Re: 2012-2013: HPA Weekly National Influenza Reports.

    Summary
    HPA Weekly National Influenza Report
    Summary of UK surveillance of influenza and other seasonal respiratory illnesses
    3 January 2013 – Week 1 report (up to week 52 data)

    Increases continue to be seen for several indicators of influenza activity. A letter has been issued to the NHS that GPs may now prescribe antiviral medicines for the prophylaxis and treatment of influenza in accordance with NICE guidance.
    Due to bank holidays in week 52 (ending 30 December 2012), GP surgeries were only open for three days which will have impacted on GP consultation rates – data should be interpreted with caution.

     Overall weekly influenza GP consultation rates across the UK
    o In week 52 (ending 30 December 2012), the weekly primary care ILI consultation rate increased in England (32.7 per 100,000) Scotland (37.1 per 100,000) and Northern Ireland (43.7 per 100,000) and decreased in Wales (3.4 per 100,000).
    o In week 52 2012, the weekly proportion of NHS Direct calls for cold/flu increased and the proportion for fever (5-14 yrs) decreased slightly but both remained above their respective influenza thresholds of 1.6% and 11.7%.
    o 12 acute respiratory disease outbreaks (seven in care homes, three in schools and two in hospitals) have been reported in the past seven days. Out of the three with a virological result available, one was confirmed as influenza B, one was influenza A(unsubtyped) and one was RSV.

     Virology
    o 138 (16.6%) of the 684 respiratory specimens reported to DataMart (England) tested positive for influenza in week 52 (110 B, 14 A subtype not known, 8 A(H1N1)pdm09 and 6 A(H3)).
    o The proportion of samples positive increased slightly for RSV and hMPV, decreased for rhinovirus and remained stable for adenovirus and parainfluenza.
    o Five influenza B positive detections were recorded through the two English GP-based sentinel schemes in week 52.

     Disease severity and mortality
    o 40 new admissions to ICU/HDU with confirmed influenza (21 B, 11 A(subtype not known), seven A(H3N2), and one A(H1N1)pdm09) were reported through the USISS mandatory ICU surveillance scheme across the UK (137 Trusts in England) in week 52. 63 new hospitalised confirmed influenza cases have been reported through the USISS sentinel hospital network across England (24 Trusts).
    o No excess all-cause mortality was seen by age group or region in week 50 across the UK as calculated with the EuroMOMO algorithm.

     Influenza vaccination
    o Up to week 50, 71.7% of people in England aged 65 years and over had received the 2012/13 influenza vaccine (provisional data). For those in a clinical risk group aged under 65 years, provisional uptake was 48.3%.
    o Amongst pregnant women, the provisional uptake was 39.6%.
    o Provisional data from the second monthly collection of influenza vaccine uptake by frontline healthcare workers show 40.8% were vaccinated by 30 November 2012.

     International situation
    o During week 51 2012, despite surveillance limitations over the holiday period, there are clear indications that influenza transmission continues to rise in Europe, although the impact and characteristics of the epidemics are yet to be determined.
    o Many countries of the northern hemisphere temperate region are now reporting elevated detections of influenza, particularly in North America.

     Novel coronavirus 2012
    o The total number of global laboratory confirmed human cases of novel coronavirus 2012 reported to WHO currently stands at nine. In the UK there has been one confirmed imported case to date and the public health response around this case has been published here. Information on management and guidance of possible cases is available on the HPA website.
    ...
    In week 52, 40 new admissions to ICU/HDU with confirmed influenza infection (21 B, 11 A unknown
    subtype, seven A(H3N2) and one A(H1N1)pdm09) were reported across the UK (137/163 Trusts in England)
    through the USISS mandatory ICU scheme (Figures 12 and 13). Five new confirmed influenza deaths were
    reported in week 52 2012. A total of 115 admissions (46 B, 35 A unknown subtype, 19 A(H3N2) and 15
    A(H1N1)pdm09) have been reported since week 40 2012. Nine confirmed influenza deaths have been
    reported across the UK in ICU/HDU since week 40 (Figure 12).

              o 218 influenza positive detections (97 B, 66 A subtype not known, 38 A(H3) and 17 A(H1N1)pdm09) were recorded through the DataMart scheme (overall positivity of 23.2% compared to 19.2% the previous week).
              o The proportion of samples positive in DataMart (England) increased for rhinovirus and remained stable for RSV, hMPV, adenovirus and parainfluenza.
              o 42 influenza positive detections were recorded through the two English GP-based sentinel schemes in week 5 (18 B, 17 A(H3) and 7 A(H1N1)pdm09), giving a positivity of 42% compared to 44% in week 4.

               Disease severity and mortality
              o 36 new admissions to ICU/HDU with confirmed influenza (14 A(subtype not known), 12 B, five A(H1N1)pdm09 and five A(H3N2) were reported through the USISS mandatory ICU surveillance scheme across the UK (137 Trusts in England) in week 5. 78 new hospitalised confirmed influenza cases have been reported through the USISS sentinel hospital network across England (26 Trusts).
              o In week 5 2013, overall excess all-cause mortality was seen in Northern Ireland and none was seen in England, Scotland and Wales. This data is provisional due to the time delay in death registration.

               Influenza vaccination
              o Up to week 4, 73.2% of people in England aged 65 years and over had received the 2012/13 influenza vaccine (provisional data). For those in a clinical risk group aged under 65 years, provisional uptake was 50.8%. Amongst pregnant women, the provisional uptake was 39.7%.
              o A mid-season analysis assessing the effectiveness of the trivalent influenza vaccine in the UK in this season (2012/13) has been published in Eurosurveillance. An overall adjusted vaccine effectiveness of 51% (95% confidence interval 27% - 68%) was reached against all laboratory-confirmed influenza in primary care, which is within the expected range of effectiveness of a trivalent influenza vaccine.

               International situation
              o During week 4 2013, influenza activity continued to rise across Europe, although the epidemic may have passed its peak in some north-western countries.
              o Influenza activity in North America remains high regionally, though nationally most indicators of transmission have begun to decrease.
              o The patterns of influenza virus co-circulation being identified in Europe are different from that being reported by North America.

                Re: 2012-2013: HPA Weekly National Influenza Reports.

                this is interesting ... will the B-wave that they had,
                with peak in week 52,
                protect them now against A, which is peaking in the
                neighbor countries ?
                Or will they get another A-peak ?

                  HPA Weekly National Influenza Report
                  Summary of UK surveillance of influenza and other seasonal respiratory illnesses
                  14 February 2013 Week 7 report (up to week 6 data)

                  Indicators of influenza activity across England have either remained stable or decreased compared to the previous week. Outbreaks and hospitalisations continue to be reported. A letter has been issued to the NHS that GPs may now prescribe antiviral medicines for the prophylaxis and treatment of influenza in accordance with NICE guidance.

                   Overall weekly influenza GP consultation rates across the UK o In week 6 (ending 10 February 2013), the weekly primary care ILI consultation rate remained stable in England (14.5 per 100,000), increased in Northern Ireland (61.4 per 100,000) and decreased slightly in Wales (16.1 per 100,000) and Scotland (41.6 per 100,000).
                  o In week 6 2013, the weekly proportion of NHS Direct calls for cold/flu and fever (5-14yrs) remained below their respective influenza thresholds of 1.6% and 11.7%.
                  o 22 acute respiratory disease outbreaks have been reported in the past seven days. Seven had a virological result available (three B, three influenza A(unsubtyped) and one A(H3)).

                   Virology
                  o 200 influenza positive detections (81 B, 52 A(H3), 47 A subtype not known and 20 A(H1N1)pdm09) were recorded through the DataMart scheme (overall positivity of 20.9% compared to 25.2% the previous week).
                  o The proportion of samples positive in DataMart (England) increased slightly for hMPV and parainfluenza and remained stable for RSV, adenovirus and rhinovirus.
                  o 17 influenza positive detections were recorded through the two English GP-based sentinel schemes in week 6 (7 B, 5 A(H3) and 5 A(H1N1)pdm09), giving a positivity of 47% compared to 50% in week 5.

                   Disease severity and mortality
                  o 34 new admissions to ICU/HDU with confirmed influenza (15 B, 13 A(subtype not known), four A(H3N2) and two A(H1N1)pdm09 were reported through the USISS mandatory ICU surveillance scheme across the UK (133 Trusts in England) in week 6. 57 new hospitalised confirmed influenza cases have been reported through the USISS sentinel hospital network across England (25 Trusts).
                  o In week 6 2013, no overall excess all-cause mortality was seen across the UK through the EuroMOMO algorithm. This data is provisional due to the time delay in death registration.

                   Influenza vaccination
                  o Up to week 4, 73.2% of people in England aged 65 years and over had received the 2012/13 influenza vaccine (provisional data). For those in a clinical risk group aged under 65 years, provisional uptake was 50.8%. Amongst pregnant women, the provisional uptake was 39.7%.

                   Novel Coronavirus
                  o In the past seven days, two cases of novel coronavirus have been diagnosed in UK residents in the UK. The first case had recently travelled to the Middle East and Pakistan. The second case is a family member and was in close personal contact with the first case, with no recent travel history. While it is understood the second case had an existing medical condition that may make them more susceptible to respiratory infections, this suggests person-to-person transmission has occurred and that it occurred in the UK. Close contacts are being identified and followed up.
                  o These latest two cases bring the total number of confirmed cases globally to 11.

                   International situation
                  o During week 5 2013, influenza activity continued to rise across Europe. In a few countries the epidemics seemed to have passed their peaks, although some countries experienced a resurgence of ILI rates.
                  o Influenza activity in North America remains high, although it has decreased in most areas in the United States.
                  o The patterns of influenza virus co-circulation being identified in Europe are different from that being reported by North America.
                  ...
                  -In week 6, 34 new admissions to ICU/HDU with confirmed influenza infection (15 B, 13 A unknown subtype,
                  four A(H3N2) and two A(H1N1)pdm09) were reported across the UK (133/163 Trusts in England) through
                  the USISS mandatory ICU scheme (Figures 12 and 13). Two new confirmed influenza deaths were reported
                  in week 6 2013. A total of 450 admissions (196 B, 117 A unknown subtype, 75 A(H3N2) and 62
                  A(H1N1)pdm09) have been reported since week 40 2012. Forty-seven confirmed influenza deaths (15 B, 15

                      28 February 2013 Week 9 report (up to week 8 data)

                      Summary

                      Indicators of influenza activity across England continue to show influenza is circulating: influenza B positivity is decreasing while influenza A(H3) positivity is increasing. A letter has been issued to the NHS that GPs may now prescribe antiviral medicines for the prophylaxis and treatment of influenza in accordance with NICE guidance.

                       Overall weekly influenza GP consultation rates across the UK o In week 8 (ending 24 February 2013), overall weekly influenza GP consultations decreased in England (15.3 per 100,000), Northern Ireland (43.7 per 100,000), Scotland (25.2 per 100,000) and Wales (11.2 per 100,000).

                      o The proportion of samples positive in DataMart (England) increased slightly for hMPV and remained stable for parainfluenza, RSV, adenovirus and rhinovirus.
                      o 8 influenza positive detections were recorded through the two English GP-based sentinel schemes in week 8 (8 B), a positivity of 40.0%.

                       Disease severity and mortality
                      o 37 new admissions to ICU/HDU with confirmed influenza (14 A(subtype not known), 11 A(H1N1)pdm09, 7 B, and 5 A(H3N2) were reported through the USISS mandatory ICU surveillance scheme across the UK (141 Trusts in England) in week 8. 61 new hospitalised confirmed influenza cases have been reported through the USISS sentinel hospital network across England (27 Trusts).
                      o In week 8 2013, no overall excess all-cause mortality was seen across the UK through the EuroMOMO algorithm. This data is provisional due to the time delay in death registration.

                       Influenza vaccination
                      Influenza vaccination
                      o Provisional data from the final fourth monthly collection of seasonal influenza vaccine uptake show 73.4% of people aged 65 years and over, 51.3% of those aged under 65 years in a clinical risk group and 40.3% of pregnant women were vaccinated by 31 January 2013 from 99.3% of GP practices.
                      o Provisional data from the final fourth monthly collection of influenza vaccine uptake by frontline healthcare workers show 45.9% were vaccinated by 31 January 2013 from 97.0% of Trusts (including PCTs).
                      o WHO have published the recommended composition of influenza virus vaccines for use in the 2013/14 northern hemisphere influenza season.

The two further cases are family members in contact with the first case, with no recent travel history. Close contacts are being identified and followed up and no further secondary cases have been identified to date.
                      o These most recent three cases bring the total number of confirmed cases globally to 13.

                       International situation
                      o During week 7 2013, influenza activity remained substantial across Europe but an increasing number of countries are reporting indications of declining transmission.
                      o Influenza activity in North America remains elevated but is decreasing in most areas.
                      o The patterns of influenza virus co-circulation being identified in Europe are different from that being reported by North America.

                        Indicators of influenza activity across England continue to show influenza is circulating, although the proportion of samples positive for influenza is decreasing. A letter has been issued to the NHS that GPs may now prescribe antiviral medicines for the prophylaxis and treatment of influenza in accordance with NICE guidance.

                         Overall weekly influenza GP consultation rates across the UK o In week 9 (ending 3 March 2013), overall weekly influenza GP consultations remained stable in England (15.1 per 100,000), Northern Ireland (44.8 per 100,000), Scotland (25.4 per 100,000) and Wales (9.6 per 100,000).
                        o In week 9 2013, the weekly proportion of NHS Direct calls for cold/flu and fever (5-14yrs) remained below their respective influenza thresholds of 1.6% and 11.7%.
                        o 30 acute respiratory disease outbreaks have been reported in the past seven days. 17 had a virological result available (14 influenza A (unsubtyped), one influenza A(H1N1)pdm09, one RSV and one seasonal coronavirus).

                         Virology
                        o 183 influenza positive detections (76 A(H3), 49 A subtype not known, 41 B and 17 A(H1N1)pdm09) were recorded through the DataMart scheme (overall positivity of 18.2% compared to 24.0% the previous week).
                        o The proportion of samples positive in DataMart (England) increased slightly for adenovirus and remained stable for parainfluenza, RSV, hMPV and rhinovirus.
                        o 19 influenza positive detections were recorded through the two English GP-based sentinel schemes in week 9 (12 A(H3), 6 A(H1N1)pdm09 and 1 B), giving a positivity of 28.8% compared to 49.4% in week 8.

                         Disease severity and mortality
                        o 48 new admissions to ICU/HDU with confirmed influenza (16 A(subtype not known), 13 B, 11 A(H1N1)pdm09, and 8 A(H3N2) were reported through the USISS mandatory ICU surveillance scheme across the UK (141 Trusts in England) in week 9. 56 new hospitalised confirmed influenza cases have been reported through the USISS sentinel hospital network across England (25 Trusts).
                        o In week 9 2013, no overall excess all-cause mortality was seen across the UK through the EuroMOMO algorithm. This data is provisional due to the time delay in death registration.

                         Influenza vaccination
                        o Provisional data from the final fourth monthly collection of seasonal influenza vaccine uptake show 73.4% of people aged 65 years and over, 51.3% of those aged under 65 years in a clinical risk group and 40.3% of pregnant women were vaccinated by 31 January 2013 from 99.3% of GP practices.
                        o Provisional data from the final fourth monthly collection of influenza vaccine uptake by frontline healthcare workers show 45.9% were vaccinated by 31 January 2013 from 97.0% of Trusts (including PCTs).
                        o WHO have published the recommended composition of influenza virus vaccines for use in the 2013/14 northern hemisphere influenza season.

                         Novel Coronavirus
                        o In February 2013, three cases of novel coronavirus have been diagnosed in UK residents in the UK. The first case had recently travelled to the Middle East and Pakistan. The two further cases are family members in contact with the first case, with no recent travel history. Close contacts are being identified and followed up and no further secondary cases have been identified to date.
                        o These three cases, along with a new case reported in Saudi Arabia, brings the total number of confirmed cases globally to 14.

                         International situation
                        o During week 8 2013, influenza activity remained substantial across Europe but an increasing number of countries are reporting indications of declining transmission.
                        o Influenza activity in North America remains elevated but is continuing to decrease in most areas.
                        o The patterns of influenza virus co-circulation being identified in Europe are different from that being reported by North America.
                        ...
                        -In week 9, 48 new admissions to ICU/HDU with confirmed influenza infection (16 A unknown subtype, 13 B,
                        11 A(H1N1)pdm09 and eight A(H3N2) were reported across the UK (141/163 Trusts in England) through the
                        USISS mandatory ICU scheme (Figures 12 and 13). A total of 640 admissions (250 B, 174 A unknown

                                Re: UK: 2012-2013: HPA Weekly National Influenza Reports.

                                PHE Weekly National Influenza Report
                                Summary of UK surveillance of influenza and other seasonal respiratory illnesses
                                4 April 2013 Week 14 report (up to week 13 data)

                                Indicators of influenza activity across England are decreasing. GPs may still prescribe antiviral medicines for the prophylaxis and treatment of influenza in accordance with NICE guidance.
                                 Overall weekly influenza GP consultation rates across the UK o In week 13 (ending 31 March 2013), overall weekly influenza GP consultations decreased in England (7.7 per 100,000), Scotland (14.2 per 100,000) and Wales (9.5 per 100,000) and increased slightly in Northern Ireland (37.4 per 100,000).
                                o In week 13 2013, the weekly proportion of NHS Direct calls for cold/flu and fever (5-14yrs) remained below their respective influenza thresholds of 1.6% and 11.7%.
                                o 10 new acute respiratory disease outbreaks have been reported in the past seven days. Eight had a virological result available (four influenza A (unsubtyped), two A(H3) and two B).

                                 Virology
                                o 134 influenza positive detections (54 A(H3), 40 A subtype not known, 25 B and 15 A(H1N1)pdm09) were recorded through the DataMart scheme (overall positivity of 14.9% compared to 19.1% the previous week).
                                o The proportion of samples positive in DataMart (England) increased slightly for hMPV and remained stable for adenovirus, parainfluenza, RSV and rhinovirus.
                                o 2 influenza positive detections were recorded through the two English GP-based sentinel schemes in week 13 (2 A(H1N1)pdm09), giving a positivity of 15.4% compared to 28.0% in week 12.

                                 Disease severity and mortality
                                o 26 new admissions to ICU/HDU with confirmed influenza (15 A(subtype not known), six A(H3N2), four A(H1N1)pdm09 and one B were reported through the USISS mandatory ICU surveillance scheme across the UK (120 Trusts in England) in week 13. 38 new hospitalised confirmed influenza cases have been reported through the USISS sentinel hospital network across England (23 Trusts).
                                o In week 13 2013, excess all-cause mortality was seen in England in 65+ year olds through the EuroMOMO algorithm. This data is provisional due to the time delay in death registration.

                                 International situation
                                o During week 12 2013, influenza activity in Europe continued to decline or had already returned to baseline levels; after more than three months of active transmission, the 2012/13 influenza season is waning.
                                o Influenza activity in North America continues to decrease overall.
                                o Low levels of influenza activity were reported across the tropical regions of the world and activity in countries of the southern hemisphere remains at inter-seasonal levels.
                                o Nine cases of human infection with influenza A(H7N9) in China have been reported by ECDC. Three of the cases have died and the remaining six are in a critical condition. To date no epidemiological link between the cases has been identified.
