Re: UK: 2012-2013: HPA / PHE Weekly National Influenza Reports.
PHE Weekly National Influenza Report
Summary of UK surveillance of influenza and other seasonal
respiratory illnesses
11 April 2013 ? Week 15 report (up to week 14 data)
Influenza is continuing to circulate in England and outbreaks continue to be reported, particularly in care
homes. GPs may still prescribe antiviral medicines for the prophylaxis and treatment of influenza in
accordance with NICE guidance.
...
Virological surveillance
In week 14 2013, 92 (12.4%) of the 743 respiratory specimens
reported to the English Respiratory Data Mart system were
positive for influenza (75 A unsubtyped, 41 A(H3), 10
A(H1N1)pdm09 and 10 B) compared to 16.0% in week 13
...
Severe disease surveillance
In week 14 2013, 21 new admissions of confirmed influenza cases to ICU/HDU (13 A unknown subtype, four
A(H3N2), 3 B and one A(H1N1)pdm09) and two confirmed influenza deaths in ICU/HDU have been reported through
the national USISS mandatory ICU scheme across the UK (133 Trusts in England) (Figure 4). Twenty-seven new
hospitalised confirmed influenza cases have been reported through the USISS sentinel hospital network across
England (18 Trusts) (10 A(H3N2),seven B, six A(H1N1)pdm09, four A(unknown subtype).
In week 13 2013 (which had one bank holiday), an estimated 9,280 all-cause deaths were registered in England and
Wales (source: Office for National Statistics). This is less than the 11,075 estimated death registrations in week 12
and below the 95% upper limit of expected death registrations for this time of year as calculated by the HPA.
In week 14 2013, significant excess mortality above threshold was seen in 65+ year olds in England after correcting
ONS disaggregate data for reporting delay with the standardised EuroMOMO algorithm (Table 1). By region this
excess was localised to the North West. This excess coincides with continued circulating influenza and low
temperatures. This data is provisional due to the time delay in registration and the Easter bank holidays and so
numbers may vary from week to week.
