Influenza virus characterisation: Summary Europe February 2013
During the 2012/2013 season A(H1N1)pdm09, A(H3N2) and B/Victoria- and B/Yamagata- lineage influenza viruses have been detected in ECDC-affiliated countries. The relative prevalence varied between countries. Type A and type B viruses have co-circulated in similar proportions.
Type A and type B viruses have co-circulated in similar proportions.
A(H1N1)pdm09 viruses have been detected at comparable levels to A(H3N2) viruses.
A(H1N1)pdm09 viruses continued to show genetic drift from the vaccine virus, A/California/07/2009, but the vast majority remained antigenically similar to it.
The vast majority of A(H3N2) viruses have been antigenically and genetically similar to cell-propagated A/Victoria/361/2011, the prototype vaccine virus for the 2012/2013 influenza season.Viruses of the B/Yamagata lineage predominated over those of the B/Victoria lineage.
B/Victoria lineage viruses were antigenically similar to cell-propagated reference viruses of the B/Brisbane/60/2008 genetic clade.
Recent B/Yamagata-lineage viruses fell into two antigenically distinguishable genetic clades: clade 2 represented by B/Estonia/55669/2012 and clade 3 represented by B/Wisconsin/1/2010 (the recommended vaccine component for the 2012/2013 influenza season).

Influenza virus characterisation - Summary Europe, March 2022
21 Apr 2022 - This is the fifth report for the 2021-2022 influenza season. As of week 13 2022 90 644 influenza detections across the WHO European Region were reported to the European Surveillance System TESSy ), a rise of over 87 000 since week 47/2021 with most being reported from week 49/2021 onwards.
Chikungunya virus disease - Annual Epidemiological Report for 2020
5 Apr 2022 - For 2020, 24 EU/EEA countries reported 59 cases of chikungunya virus disease, of which 52 (88%) were confirmed. This was the lowest number of cases reported at the EU/EEA level since 2016. The EU/EEA notification rate was <0.1 cases per 100 000 population.
