Report published 12 April 2012

Limited access to GP services on Good Friday 6 April 2012 will have impacted on GP consultation rates, so data should be interpreted with caution.

GP consultation rates remain low and most indicators of influenza activity have decreased but sporadic outbreaks continue to be reported.

• Weekly influenza GP consultation rates remain low in England, Wales, Scotland and Northern Ireland.
• In week 14 (ending 8 April 2012), the weekly primary care ILI consultation rate remained low in England (5.5 per 100,000), Scotland (11.7 per 100,000), Northern Ireland (17.0 per 100,000) and Wales (1.9 per 100,000).
• The weekly proportion of NHS Direct calls for cold/flu and fever (5-14yrs) remain below the early warning thresholds for influenza in week 14.
• Fourteen new acute respiratory disease outbreaks were reported across the UK (seven in England, four in Scotland, two in Northern Ireland and one in Wales) in week 14 2012 compared to seven in week 13.
• 36 (7.1%) of the 507 respiratory specimens reported to Data Mart (England) tested positive for influenza in week 14, a slight decrease in positivity compared to week 13. The majority of positive samples were influenza A(H3) (13 A(H3), 12 A (subtype not known) and 11 B). The proportion of samples positive for RSV decreased slightly, with the highest positivity remaining in under five year olds. The proportion of samples positive increased for rhinovirus, decreased for adenovirus and remained stable for hMPV and parainfluenza.
• Three influenza A(H3) and one B were recorded in the UK sentinel GP schemes in week 14 2012, an overall positivity of 8.9% compared to 20.9% in week 13.
• The majority of A(H3N2) viruses are antigenically similar to the 2011/12 A(H3N2) vaccine component.
• Ten new admissions to ICU/HDU with confirmed influenza were reported through the USISS mandatory scheme across the UK in week 14 compared to 14 in week 13.
• No new ICU/HDU confirmed influenza deaths have been reported through the USISS mandatory scheme across the UK in week 14.
• No excess all-cause mortality was seen by age group and by region in week 14 as calculated by the HPA with the EuroMOMO algorithm. No excess mortality was seen in Scotland in week 14 2012.
• Following a WHO consultation, it is recommended that vaccines for use in the 2012/13 northern hemisphere influenza season contain the following viruses: an A/California/7/2009 (H1N1)pdm09-like virus, an A/Victoria/361/2011 (H3N2)-like virus and a B/Wisconsin/1/2010-like virus.
• In Europe, the decrease in the proportion of influenza-positive sentinel specimens and the growing number of countries reporting continuously decreasing trends in the incidence of ILI/ARI indicate that the epidemic has passed its peak in almost all countries. As often observed late in the season, the proportion of type B virus influenza detections has been increasing over the past seven weeks. A proportion of A(H3) viruses characterised have not perfectly matched the current vaccine strain, which is consistent with the decision of WHO to recommend a change of A(H3N2) strain in the vaccine in 2012/13.
• Elsewhere in the temperate regions of the Northern hemisphere influenza activity appears to be reaching its peak or decreasing in most countries and it is mainly dominated by A(H3) viruses.
• Countries in the tropical zone are mostly reporting low levels of activity and transmission in the temperate countries of the southern hemisphere is at low levels.
• HPA guidance on infection control and the use of antiviral agents for the treatment and prophylaxis of influenza this season is available on the HPA website.
