This is the fourth 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 in the season 2011/2012. Please refer to the technical document for further information.
Clinical influenza activity is decreasing and is below the threshold for normal seasonal activity overall. Virological influenza activity decreased slightly compared to the previous week. Levels of non-influenza seasonal respiratory pathogens overall were in line with expected levels, with the exception of the level of parainfluenza virus reports which were slightly higher than at the same time last year
There is 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.
