Summary of the influenza 2014–2015 season in Europe
Increased influenza activity started in week 51/2014 this season when the percentage of influenza positive laboratory tests crossed the 10% threshold. The season lasted for 21 weeks until week 19/2015, when the positivity rate dropped below 10%. The peak of the season - with the highest proportion of specimens tested positive (55%) - occurred in week 07/2015. The peak varied between countries, occurring in week 04/2015 in Bulgaria and Portugal, and between weeks 05/2015 and 08/2015 in most central European countries.
Summary of the influenza 2012–2013 season in the WHO European region

Target 3.1. Support to national surveillance networks
National surveillance networks connecting clinical/public health laboratories for reporting diagnostic information to surveillance databases and linking microbiological and epidemiological information are essential for efficient communicable disease and drug resistance surveillance and early infectious threat detection.
Target 3.2. Active participation in EU/EEA disease networks
Active participation and collaboration between experts in EU disease networks promotes exchange of best practice and capacity building, which foster sufficient collective capacity in the EU for threat detection, investigation, disease surveillance and epidemic preparedness.
Target 3.3. National outbreak response support
Preparation and involvement of the national reference laboratory capacities and staff in outbreak monitoring and response activities in collaboration with clinicians, epidemiologists, and microbiologists ensure the effective contribution of laboratory testing to support epidemic detection and control.
Target 3.4. (Re)-emerging disease laboratory preparedness and response support
Up-to-date diagnostic capability for rare and (re)-emerging diseases and effective channels for collaboration are critical for laboratory preparedness and the deployment of timely and reliable emergency response to national and cross-border events.

Summary of the influenza 2016–2017 season in Europe
The influenza season 2016–2017 has now come to an end in Europe. In week 17/2017, all EU/EEA countries reported low influenza activity and the positivity rate (proportion of influenza virus positives among all tested specimens) falling below the 10% benchmark to 9.9%. For the previous six weeks, almost all EU/EEA countries had reported low influenza activity.
Influenza surveillance for the 2017-2018 season is starting
ECDC monitors and reports on influenza transmission and virus circulation in Europe on a weekly basis throughout the flu season, in collaboration with WHO Regional Office for Europe, in the report Flu News Europe.
