This report provides an update on influenza and other seasonal respiratory pathogen activity to the week ending 23 November 2014. For this season, we will provide detailed influenza update reports on a four-weekly 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.
Influenza clinical and virological activity remained low overall.
From week 44 to week 47, two influenza cases with severe infection requiring intensive care management (ICU cases) were reported to HPS (2 A(not subtyped)).
Over the past four weeks, the levels of seasonal non-influenza respiratory pathogens reported through sentinel sources and non-sentinel sources remained in line with expected levels, with
the exception of adenovirus and human metapneumovirus (hMPV), levels of which increased and were above expected levels for this time of the year. Increasing detections of respiratory
syncytial virus (RSV) are consistent with the start of the annual RSV wave.
Erratum dated 5 Dec 2014. Version 1.1
Three changes were made to section 6:
Bullet point 1 – correction of week number from week 44 to week 47:
“To week 47, provisional data suggested that vaccine uptake overall for Scotland, for those aged 65 years and above was similar to the uptake at the same time last year; 68.9% (2014) vs 68.7% (2013).[…].”
Bullet point 2 – correction of year from 2014 to 2013
“The uptake in pregnant women groups was similar to those achieved at the same time last year: 39.4% in those without risk factors and 54.5% in those with risk factors. This compared to 38.2% and 54.6%, respectively, in week 47, 2013.”
Bullet point 5 – correction of cumulative uptake from 37.1% to 45.7%
“To week 47, preliminary data on influenza vaccination in primary schools showed a cumulative uptake of 45.7%, with an average uptake of 70.9% per school session already held.”
