Summary

Influenza activity remains at low levels in week 48 (ending 29 November 2015)
 Community influenza surveillance
o In week 48, there were further increases in a number of respiratory indicators in children aged <5 year, these
increases are in line with reports of increasing respiratory syncytial virus (RSV) activity.
o Three new acute respiratory outbreaks have been reported in the past seven days. One from a hospital testing
positive for RSV, one from a care home and another from a school with no test results available.
 Overall weekly influenza GP consultation rates across the UK
o In week 48, overall weekly influenza-like illness GP consultations was low in England (9.9 per 100,000), Wales (4.8
per 100,000), Scotland (5.3 per 100,000) and Northern Ireland (18.0 per 100,000).
o Weekly influenza-like illness consultations rates also remain low in week 48 through the GP In Hours Surveillance
system.
 Influenza-confirmed hospitalisations
o Five new admissions to ICU/HDU with confirmed influenza (one influenza A(H1N1pdm09), three A(unknown
subtype) and one B) were reported through the USISS mandatory ICU/HDU surveillance scheme across the UK
(128 Trusts in England) in week 47, a rate of 0.01 compared to 0.02 per 100,000 the previous week.
o Four new hospitalised confirmed influenza cases (three influenza A(H1N1pdm09) and one B) were reported
through the USISS sentinel hospital network across England (22 Trusts), a rate of 0.05 compared to 0.07 per
100,000 the previous week.
o Since week 40, one confirmed influenza admission has been reported (influenza A unknown subtype) from the five
Severe Respiratory Failure centres in England.
 All-cause mortality data
o In week 48 2015, no statistically significant excess all-cause mortality by week of death was seen through the
EuroMoMo algorithm in England overall and by age group.
o In the devolved administrations, significant excess all-cause mortality was seen in Scotland.
 Microbiological surveillance
o Two samples tested positive for influenza B through GP sentinel schemes across the UK.
o Twenty-three influenza positive detections were recorded through the DataMart scheme (eight influenza
A(H1N1)pdm09, three A(H3), one A(not subtyped) and eleven influenza B). A positivity of 1.8% was seen in week
48, a decrease from 2.0% seen in week 47, with the highest positivity in 5-14 year olds (4.8%).
 Vaccination
o Up to week 48 2015 in 73.9% 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: 38.1% in under 65
years in a clinical risk group, 37.0% in pregnant women, 66.3% in 65+ year olds, 28.4% in all 2 year olds, 29.5%
in all 3 year olds and 24.0% in all 4 year olds.
o Provisional data from the first monthly collection of influenza vaccine uptake by frontline healthcare workers show
32.4% were vaccinated by 31 October 2015 from 95.1% of Trusts, compared to 36.8% vaccinated in the previous
season by 31 October 2014.
o Provisional data from the first monthly collection of influenza vaccine uptake in children of school years 1 and 2
age show 11.8% of children of school year 1 and 11.4% of children school of school year 2 had received the
2015/16 live attenuated intranasal vaccine (LAIV) by 31 October 2015.
o Provisional data from the first monthly collection of influenza vaccine uptake in GP patients up to 31 October 2015

Summary
In week 52 2015 (ending 27 December), allowing for Christmas reporting breaks, across community/primary care
surveillance schemes, influenza activity remains at low levels, although an increase in influenza activity is now
being observed through secondary care surveillance schemes.

 Community influenza surveillance
o During week 52 selected respiratory indicators remained high but continue to be within seasonally expected levels.
o Six new acute respiratory outbreaks have been reported in the past 7 days. Five in care homes where one tested
positive for influenza A(not subtyped), one tested positive for RSV and hMPV, one tested positive for RSV only,
one tested positive for parainfluenza and one was not tested/test results were not available). The sixth outbreak
was in a hospital which tested positive for RSV.

o Due to bank holidays in week 52 (ending 27 December 2015), GP surgeries were only open for four days ? data
should therefore be interpreted with caution.
o In week 52, overall weekly influenza-like illness (ILI) GP consultations was low in England (6.6 per 100,000), Wales
(6.8 per 100,000), Scotland (12.4 per 100,000) and Northern Ireland (17.0 per 100,000).
o Weekly ILI rates also remain low in week 52 through the GP In Hours Surveillance system.

A(not subtyped) and two influenza B) were reported through the USISS sentinel hospital network across England
(20 Trusts), a rate of 0.38 compared to 0.19 per 100,000 the previous week.
o Since week 40, eight confirmed influenza admissions have been reported (four influenza A(H1N1)pdm09 and four
influenza A(unknown subtype) from the five Severe Respiratory Failure centres in England.
 All-cause mortality data

schemes across the UK.
o Eighty-seven influenza positive detections were recorded through the DataMart scheme (seventy-one influenza
A(H1N1)pdm09, twelve A(not subtyped) and four influenza B). A positivity of 8.3% was seen in week 52, an
increase from 5.5% seen in week 51, with the highest positivity in 15-44 year olds (15.4%). This is above the
threshold for 2015/16 season of 7.4%.

o Globally, influenza activity generally remained low in both hemispheres overall but there are signs of increasing
activity in the Northern hemisphere.
o Influenza activity in Europe remains low, however an increase in the positivity of samples from sentinel sources
indicates an increase in influenza activity and the start of the season.

07 January 2016 ? Week 01 report (up to week 53 data)
https://www.gov.uk/government/uploa...90370/Weekly_report_current_wk_1_7Jan2016.pdf

Summary
In week 53 2015 (ending 03 January 2016), allowing for Christmas reporting breaks, across surveillance schemes,
influenza activity has increased for several indicators, including GP ILI consultation rates, the proportion of laboratory
samples positive for influenza and influenza admissions to hospitals and ICU. There is an indication that the influenza
season has started.

 Community influenza surveillance
o During week 53, there was an increase in lower respiratory tract infections in adults over 65 years, although they continue
to be within seasonally expected levels.
o Thirteen new acute respiratory outbreaks have been reported in the past 7 days. Twelve outbreaks were in care homes
where two tested positive for influenza (one influenza A(not subtyped) and another mixed infection of influenza A(not
subtyped). The thirteenth outbreak was from the ?other? category, in an immigration removal centre, where test results
were not available.
 Overall weekly influenza GP consultation rates across the UK
o Due to bank holidays in week 53, GP surgeries were only open for three days ? data should therefore be interpreted with
caution.
o In week 53, overall weekly influenza-like illness (ILI) GP consultations has increased in England (9.6 per 100,000), Wales
(6.5 per 100,000), Scotland (8.6 per 100,000) and Northern Ireland (21.5 per 100,000).
o Weekly ILI rates remain within seasonally expected levels in week 53 through the GP In Hours Surveillance system.
 Influenza-confirmed hospitalisations
o Sixty-two new admissions to ICU/HDU with confirmed influenza (twenty-eight influenza A(H1N1)pdm09, one A(H3), thirtytwo
influenza A(unknown subtype) and one influenza B) were reported through the USISS mandatory ICU/HDU
surveillance scheme across the UK (133 Trusts in England) in week 53, a rate of 0.13 compared to 0.11 per 100,000 the
previous week. Five deaths were also reported through this scheme.

Influenza Weekly Surveillance Bulletin
Northern Ireland, Week 2 (11 January 2016 &#150; 17 January 2016)
http://www.publichealth.hscni.net/si...202%202016.pdf

Summary
 Influenza GP consultations have remained stable, while the proportion of positive influenza virological detections in Northern Ireland have increased.
 GP consultation rates for combined flu and flu-like illness (flu/FLI) remain below the 2015/16 pre-epidemic Northern Ireland threshold1 at 30.5 per 100,000 population in week 2, 2016.
 The OOH consultation rate for flu/FLI has remained stable at 8.5 per 100,000 population overall, with increases in some age groups.
 RSV activity has further decreased in week 2 and is lower than the same period during last season. 
There were ten admissions to ICU with confirmed influenza reported in week 2, 2016.
 There were three deaths in ICU patients with laboratory confirmed influenza reported in week 2, 2016.
 In week 2, 2016 significant all-cause excess mortality was reported through the EuroMOMO algorithm.
 There were no confirmed influenza outbreaks reported to PHA in week 2, 2016.
...
Comment
Data are collected on laboratory confirmed influenza patients and deaths in critical care (level 2
and level 3).
During week 2, there were ten admissions to ICU confirmed with influenza reported to the PHA -
six with influenza A (H1N1)pdm09 and four with influenza A untyped (typing awaited). There
have been a total of 27 admissions to ICU with confirmed influenza reported this season to date,
of which 21 have been confirmed as influenza A (H1N1)pdm09 and 6 as influenza A untyped
(typing awaited) (Figure 9).
Up to week 2, 2016, of the 27 ICU patients with confirmed influenza 18 had co-morbidities.
Provisional data shows that 16 of the 27 cases met the criteria for influenza vaccine and 5 had
received it (Table 4).
There were three deaths in ICU patients with laboratory confirmed influenza reported since the
last bulletin. To date, there have been 6 deaths in ICU patients with laboratory confirmed
influenza.
...
Mortality Data
Weekly mortality data is provided from Northern Ireland Statistics and Research Agency. The
data relates to the number of deaths from selected respiratory infections (some of which may be
attributable to influenza, and other respiratory infections or complications thereof) registered
each week in Northern Ireland. This is not necessarily the same as the number of deaths
occurring in that period. Searches of the medical certificates of the cause of death are performed
using a number of keywords that could be associated with influenza (bronchiolitis, bronchitis,
influenza and pneumonia). Death registrations containing these keywords are presented as a
proportion of all registered deaths.

...
Comment
During week 2, the proportion of registered deaths from specific respiratory infections decreased
to 29% from 32% in week 1.
In week 2, there were 348 registered deaths, of which 100 related to specific respiratory
infections (29%). The proportion of deaths attributed to specific respiratory infections is lower
than the same period in both 2014/15 and 2013/14.

EuroMOMO
Significant excess all-cause mortality was reported for week 2 in Northern Ireland. Significant
excess all-cause mortality has also been reported retrospectively for weeks 52, 53 and 1.
Therefore including the previous report of excess all-cause mortality in week 49, excess allcause
mortality has been reported in five weeks of this influenza season.
Please note this data is provisional due to the time delay in registration; numbers may vary from
week to week.

-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.

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
