This report provides an update on influenza and other seasonal respiratory pathogen activity for the
week ending 20 May 2012. This is the last weekly report of the influenza season 2011/2012. 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), 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 a different method this season. Please refer to the technical document for further information on this.
Clinical influenza activity is well below the threshold for normal seasonal activity and virological
influenza activity is low. With the exception of recent rises in rhinovirus and adenovirus reports through
ECOSS, and an increase in parainfluenza reports received through ECOSS and the GP sentinel
scheme, levels of non-influenza seasonal respiratory pathogen reporting are within expected levels for
this time of year.
