PHE Weekly National Influenza Report
Summary of UK surveillance of influenza and other seasonal respiratory
illnesses
30 January 2014 ? Week 5 report (up to week 4 data)
http://www.hpa.org.uk/webc/HPAwebFil.../1317140698495

Summary

The majority of indicators of influenza activity are at similar levels in week 4 compared to week 3,
although the number of influenza-confirmed admissions to ICU/HDU has increased. A letter has now
been issued recommending the use of antivirals where appropriate.
 Overall weekly influenza GP consultation rates across the UK
o In week 4 (ending 26 January 2014), overall weekly influenza GP consultations remained low in
England (7.2 per 100,000), Wales (5.7 per 100,000), Scotland (8.4 per 100,000) and Northern
Ireland (22.9 per 100,000)).
o Nationally, there have been slight increases in selected respiratory indicators during week 4
including acute respiratory and upper respiratory tract infections, particularly in children aged 0-4
years.
o Seven new acute respiratory outbreaks have been reported in the past seven days across the UK
(three in hospitals, two in care homes, one in a school and one in a nursery). Where tested, two
were positive for A(H1N1)pdm09, one influenza A (not subtyped), one RSV and one rhinovirus.
 Virology
o In week 4 2014, 57 influenza positive detections were recorded through the DataMart scheme (32
A(H1N1)pdm09, seven A(H3), 16 A(not subtyped) and two B, a positivity of 8.2% compared to 7.8%
in week 3).
o Five samples were positive for influenza through the English GP sentinel schemes (four
A(H1N1)pdm09 and one A(H3), positivity of 9.1%).
 Disease severity and mortality
o 31 new admissions to ICU/HDU with confirmed influenza (21 A unknown subtype, nine
A(H1N1)pdm09 and one A(H3N2)) and no confirmed influenza deaths were reported through the
USISS mandatory ICU surveillance scheme across the UK (137 Trusts in England) in week 4. 36
new hospitalised confirmed influenza cases were reported through the USISS sentinel hospital
network across England (26 Trusts).
o In week 4 2014, no excess all-cause mortality by week of death was seen across the UK through
the EuroMOMO algorithm and none has been reported since week 40 2013.
 Vaccination
o Up to week 4 2014 in 71.3% of GP practices reporting weekly to Immform, the provisional
proportion of people in England who had received the 2013/14 influenza vaccine in targeted groups
was as follows: 42.6% in all 2 year olds, 39.3% in all 3 year olds, 51.3% in under 65 years in a
clinical risk group, 39.6% in all pregnant women and 72.9% in 65+ year olds.
o Provisional data from the third monthly collection of influenza vaccine uptake in health care workers
show 53.1% were vaccinated by 31 December 2013 from 95.2% of Trusts, compared to 44.0%
vaccinated the previous season by 30 December 2012.
 International situation
o Overall influenza activity in North America remains high.
o Influenza transmission is increasing across the EU/EEA region.
...
-In week 4, 31 new admissions to ICU/HDU with confirmed influenza infection (21 A unknown subtype, nine
A(H1N1)pdm09 and one A(H3N2)) were reported across the UK (137/156 Trusts in England) through the USISS
mandatory ICU scheme (Figures 10 and 11) compared to 21 in week 3. No new confirmed influenza deaths were
reported in week 4 2013. A total of 158 admissions (67 A(H1N1)pdm09, 78 A(unknown), nine B and four A(H3N2))
and seven confirmed influenza deaths have been reported since week 40 2013.

20 March 2014 ? Week 12 report (up to week 11 data)

Summary

Influenza continues to circulate as evidenced by ongoing influenza-confirmed ICU/HDU and hospital
admissions, with indicators suggesting activity is starting to decrease. A letter has been issued
recommending the use of antivirals where appropriate.
 Overall weekly influenza GP consultation rates across the UK
o In week 11 (ending 16 March 2014), overall weekly influenza GP consultations remained low in
England (3.1 per 100,000), Wales (5.5 per 100,000), Scotland (12.7 per 100,000) and Northern
Ireland (39.2 per 100,000)).
o In week 11 syndromic surveillance indicators for influenza remain stable and similar to seasonally
expected levels.
o Six new acute respiratory influenza outbreaks have been reported in the past seven days across
the UK (four in hospitals (all A(H1N1)pdm09), one in a care home (A(not subtyped) and one in a
travelling community).
 Virology
o In week 11 2014, 117 influenza positive detections were recorded through the DataMart scheme
(55 A(H1N1)pdm09, 16 A(H3), 43 A(not subtyped) and three B, a positivity of 15.7% compared to
16.1% in week 10), with the highest positivity reported in 45-64 year olds (20.5%).
o 24 samples were positive for influenza through the English GP sentinel schemes (17
A(H1N1)pdm09, sic A(H3) and one B, positivity of 44%).
 Disease severity and mortality
o 48 new admissions to ICU/HDU with confirmed influenza (27 A(H1N1)pdm09, three A(H3N2) and
18 A unknown subtype) and one confirmed influenza death were reported through the USISS
mandatory ICU surveillance scheme across the UK (133 Trusts in England) in week 11. 20 new
hospitalised confirmed influenza cases were reported through the USISS sentinel hospital network
across England (22 Trusts).
o In week 11 2014, no excess all-cause mortality by week of death was seen across the UK through
the EuroMOMO algorithm.
 Vaccination
o In the final monthly collection up to 31 January 2014, provisional cumulative seasonal influenza
vaccine uptake from 99.8% of GP practices was 73.2% in 65 years and over (73.4% in 2012/13),
52.3% in under 65 year olds at risk (51.3% in 2012/13), 39.8% in all pregnant women (40.3% in
2012/13), 42.6% in all 2 year olds and 39.6% in all 3 year olds.
o Provisional data from the final monthly collection of influenza vaccine uptake by frontline healthcare
workers show 54.8% were vaccinated by 31 January 2014 from 99.3% of Trusts, compared to
45.9% in 2012/13.
o WHO has published recommendations for the composition of influenza virus vaccines for use in the
2014/15 northern hemisphere influenza season.
 International situation
o Overall influenza activity in North America continues to decrease.
o Influenza transmission is continuing across the EU/EEA region with considerable variation
between countries.
