This report provides an update on seasonal respiratory pathogen activity for the 2015/16 season for the week ending 17 April 2016. For this season, we will provide detailed influenza update reports once a month 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.
In Scotland, clinical influenza activity as measured by community presentations is declining. New cases of severe influenza requiring intensive care management are still being reported but are declining suggesting the burden on hospital services may be decreasing. Community circulation of influenza continues as evidence by virological reports of influenza, however, detections are decreasing when compared to previous weeks. In those viruses characterised, influenza A (H1N1) pdm2009 is the main virus identified thus far this season. Influenza B detections have been rising in recent weeks and accounted for the highest number of flu detections this week.
In week 15, detections of coronavirus and Mycoplasma pneumoniae (MPN) reported through non-sentinel sources (ECOSS) have increased and are above expected at this time of the year. The levels of all other seasonal respiratory pathogens were stable and within expected seasonal levels.
