Re: United Kingdom - 2013-2014 Influenza Surveillance Reports
PHE Weekly National Influenza Report
Summary of UK surveillance of influenza and other seasonal respiratory
illnesses
6 March 2014 ? Week 10 report (up to week 9 data)
Summary
Influenza continues to circulate as evidenced by ongoing influenza-confirmed ICU/HDU and hospital
admissions. A letter has been issued recommending the use of antivirals where appropriate.
Overall weekly influenza GP consultation rates across the UK
o In week 9 (ending 2 March 2014), overall weekly influenza GP consultations remained low in
England (3.7 per 100,000), Wales (6.8 per 100,000), Scotland (21.3 per 100,000) and Northern
Ireland (24.1 per 100,000)).
o In week 9 syndromic surveillance indicators for influenza remain stable and similar to seasonally
expected levels.
o Ten new acute respiratory influenza outbreaks have been reported in the past seven days across
the UK (two in care homes (one A(H3) and one A(not subtyped)), seven in hospitals (three
A(H1N1)pdm09, three A(not subtyped) and one influenza A(H3)/parainfluenza) and one in a school
(not tested).
Virology
o In week 9 2014, 156 influenza positive detections were recorded through the DataMart scheme (88
A(H1N1)pdm09, 35 A(H3), 32 A(not subtyped) and one B, a positivity of 18.9% compared to 17.4%
in week 8), with the highest positivity reported in 45-64 year olds (25.3%).
o 17 samples were positive for influenza through the English GP sentinel schemes (11
A(H1N1)pdm09 and six A(H3), positivity of 30%).
Disease severity and mortality
o 42 new admissions to ICU/HDU with confirmed influenza (26 A(H1N1)pdm09 and 16 A unknown
subtype) and five confirmed influenza deaths were reported through the USISS mandatory ICU
surveillance scheme across the UK (136 Trusts in England) in week 9. 69 new hospitalised
confirmed influenza cases were reported through the USISS sentinel hospital network across
England (27 Trusts).
o In week 9 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 remains elevated but is decreasing.
o Influenza transmission is continuing across the EU/EEA region with considerable variation
between countries.

Number of new admissions and fatal confirmed influenza cases in ICU/HDU (USISS mandatory ICU scheme),
UK (week 9)
-In week 9, 42 new admissions to ICU/HDU with confirmed influenza infection (26 A(H1N1)pdm09 and 16 A unknown
subtype) were reported across the UK (136/156 Trusts in England) through the USISS mandatory ICU scheme
(Figures 10 and 11) compared to 65 in week 8. Five new confirmed influenza deaths were reported in week 9 2014. A
total of 484 admissions (250 A(H1N1)pdm09, 210 A(unknown), 13 A(H3N2) and 11 B) and 38 confirmed influenza
deaths have been reported since week 40 2013.
