This report provides an update on influenza and other seasonal respiratory pathogen activity for the week ending 17 May 2015. This is the last weekly report of the influenza season 2014/2015. Over the summer (weeks 21-39) an influenza update report will be published every 4 weeks unless influenza (or other viral respiratory pathogen) activity increases significantly.
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 vaccine uptake estimates.
The GP consultation rate for influenza-like illness (ILI) and the threshold for normal seasonal activity have been calculated using a new method this season which the European Centre for Disease Prevention and Control (ECDC) is recommending should be used across the EU. Please refer to the technical document for further information.
In Scotland, both clinical and virological influenza activity decreased but there is still evidence of continued community circulation of influenza..
A CMO letter, recommending that antivirals can be used in primary care where clinically appropriate, was issued on the 18th of December 2014 and can be accessed at: http://www.sehd.scot.nhs.uk/cmo/CMO(2014)29.pdf
An updated guidance document has been issued by HPS with recommendations for the antiviral treatment and prophylaxis of influenza for the season 2014-15 (version 2.0 published on 19 February 2015).
No new laboratory confirmed influenza cases with severe infection requiring intensive care management (ICU cases) were reported to HPS within the last week. Two new closed setting outbreaks of acute respiratory infection were reported to HPS within the last week.
The levels of seasonal respiratory pathogens (rhinovirus, coronavirus, parainfluenza, adenovirus, human metapneumovirus (hMPV) and Mycoplasma pneumoniae (MPN)), reported through sentinel and non-sentinel sources (ECOSS), were stable and within expected seasonal levels. The only exception to this is respiratory syncytial virus (RSV), levels of which were increased and above expected seasonal levels.
