This is the second monthly report of the 2013/14 influenza season. This report provides an update on influenza and other seasonal respiratory pathogen activity to the week ending 24 November 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) 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.
Clinical influenza activity fluctuated over the last four weeks but remained below the threshold for normal seasonal activity overall.
From week 44 to week 47, no laboratory confirmed influenza cases with severe infection requiring intensive care management were reported to HPS.
Over the last four weeks, the overall levels of non-influenza seasonal respiratory pathogens increased. Levels of rhinovirus and parainfluenza increased and were slightly above seasonal expected levels. Increasing detections of respiratory syncytial virus (RSV) are consistent with the start of the annual RSV wave. Coronavirus, adenovirus and human metapneumovirus detections were increased but remained within seasonal expected levels.
