This report provides an update on seasonal respiratory pathogen activity for the 2015/16 season for the week ending 22 May 2016. This is the last weekly report of the influenza season 2015/2016. 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.
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 decreasing suggesting the burden on hospital services may be reducing. Continuing community circulation of influenza is evidenced by virology reports of influenza but these have decreased compared to the previous weeks. In those viruses characterised, influenza A (H1N1) pdm2009 is the main virus identified thus far this season. Influenza B detections appear to have peaked in week 13 but still account for the highest number of flu detections in the last four weeks.
In week 20, detections of Mycoplasma pneumoniae (MPN) reported through non-sentinel sources (ECOSS) have increased and are above expected levels at this time of the year. The levels of all other seasonal respiratory pathogens are stable and within expected seasonal levels.
