Influenza in Europe still below the epidemic threshold

The level of influenza-like illness and acute respiratory infection morbidity remains below the threshold levels throughout Europe and the influenza viruses A and B isolated/detected until now resemble the strains in the vaccine for this season. Fourteen national and subnational networks reported no influenza activity to the European Influenza Surveillance Scheme (EISS, http://www.eiss.org) in the week ending 25 November (week 47) (1). Only in France and Slovenia was sporadic activity observed.
