HPS Monthly National Influenza Report - Month ending 17 March 2013 21 Mar 2013

This is the sixth monthly report of the 2012/13 influenza season. For this season, we will provide detailed influenza update reports on a monthly basis with bulletin style weekly updates in the weeks in between.

This report contains summary epidemiological information on influenza-like illness (ILI) and acute respiratory illness (ARI) activity, its severity and impact in the community and secondary care settings, and estimation of vaccine uptake.

The GP consultation rate for influenza-like illness (ILI) has been calculated using the same method as last year. Please refer to the technical document for further information.

Clinical influenza activity has fallen over the last four weeks and remained below the threshold for normal seasonal activity overall. Virological influenza activity detected through the GP sentinel has fluctuated over the past few weeks but remains high. Virological activity detected through non-sentinel sources has remained relatively stable but has shown a reduction in the last week.

There were no new cases with severe infection requiring management in an intensive care unit (ICU) were reported to HPS in the last week. Since week 40 2012, a total of 102 influenza infections requiring ICU have been reported to HPS (49 A(H3), ten A(H1N1)pdm09, 11 A (subtype unknown), 32 B), 30 of these are known to have died.

We continue to see influenza outbreaks (predominantly Influenza A) in closed settings.

Levels of non-influenza seasonal respiratory pathogens overall were in line with expected levels over the last four weeks.

There is continuing evidence of significant community circulation of influenza. A CMO letter recommending that antivirals can be used in primary care where clinically appropriate was issued on the 20 December and can be accessed at: http://www.sehd.scot.nhs.uk/cmo/CMO(2012)10.pdf.
