Influenza virus characterisation - Summary Europe, November 2012
During the 2011/2012 season, A(H1N1)pdm09, A(H3N2) and B/Victoria and B/Yamagata lineage influenza viruses, with collection dates between 1 January and 30 September 2012 (weeks 1–39), have been detected in ECDC-affiliated countries.
Type A viruses predominated over type B.
A(H3N2) viruses predominated over A(H1N1)pdm09 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.
Antigenic drift of A(H3N2) viruses compared to the A/Perth/16/2209 vaccine virus resulted in a recommendation to change to an A/Victoria/361/2011-like component for the 2012/2013 influenza season.
B/Victoria lineage viruses fell within the B/Brisbane/60/2008 genetic clade and were antigenically similar to reference cell-propagated viruses of the B/Brisbane/60/2008 genetic clade.
Recent B/Yamagata-lineage viruses fell into two genetic clades in approximately equal proportions: clade 3 represented by the recommended vaccine component for the 2012/2013 influenza season, B/Wisconsin/1/2010, and clade 2 represented by B/Estonia/55669/2012. Viruses in each clade are antigenically distinguishable.
Legionnaires’ disease - Annual Epidemiological Report for 2020
10 May 2022 - Legionnaires’ disease remains an uncommon and mainly sporadic respiratory infection with an overall notification rate of 1.9 cases per 100 000 population for the EU/EEA in 2020.
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.
