HPS Weekly National Influenza Report - Week ending 05 May 2013 09 May 2013

This report provides an update on influenza and other seasonal respiratory pathogen activity for the week ending 05 May 2013. For the remainder of the season we will publish bulletin style weekly updates unless there are significant changes in influenza activity which would require more detailed reporting.

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

The GP consultation rate for influenza-like illness (ILI) has been calculated using the same method as in the season 2011/12. Please refer to the technical document for further information.

Clinical influenza activity was marginally lower than the previous week and was below the threshold for normal seasonal activity overall. Virological activity showed a continuing reducing trend in ECOSS data but showed an increase in GP Sentinel swab positivity. Please note that the data for week 18 is provisional.

One influenza case with severe infection requiring management in an intensive care unit (ICU) was reported to HPS in the last week. Since week 40 2012, a total of 125 influenza infections requiring ICU have been reported to HPS (60 A(H3), 20 A(H1N1)pdm09, 8 A (subtype unknown), 37 B), 35 of who were known to have died.

Levels of non-influenza seasonal respiratory pathogens overall were in line with expected levels, with the exception of the levels of Human Metapneumovirus, coronavirus and parainfluenza infections reports, which were slightly higher than at the same time last year.

Whilst community circulation of influenza appears to be decreasing, antivirals can still be used in primary care where clinically appropriate. The CMO letter on antiviral prescribing was issued on 20 December 2012 and can be accessed at: http://www.sehd.scot.nhs.uk/cmo/CMO(2012)10.pdf.
