This report provides an update on influenza and other seasonal respiratory pathogen activity
for the week ending 13 January 2013. 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), 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 last year. Please refer to the technical document for further information.
Clinical influenza activity is increasing but is still 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 coronavirus and parainfluenza virus which were slightly higher
than at the same time last year. Laboratory confirmed ITU cases continue to increase.
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.
