Influenza virus characterisation - Summary Europe, September 2012
Since 01 January 2012, influenza A(H1N1)pdm09, influenza A(H3N2) and influenza B/Victoria and B/Yamagata lineage viruses have been detected in ECDC-affiliated countries.
Since 1 January 2012, influenza A(H1N1)pdm09, influenza A(H3N2) and influenza B/Victoria and B/Yamagata lineage viruses have been detected and analysed in EU/EEA countries. The report summarises the findings as follows:
- Type A viruses have predominated over type B.
- A(H3N2) viruses have predominated over A(H1N1)pdm09 viruses.
- A(H1N1)pdm09 viruses continue to show genetic drift from the vaccine virus, A/California/07/2009, but the vast majority remain antigenically similar to it.
- During the last nine months, all European A(H3N2) viruses sequenced fell within five genetic clusters.
- Recent 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, represented by the recommended vaccine component for the 2012/2013 influenza season, B/Wisconsin/1/2010 (clade 3), or B/Estonia/55669/2012 (clade 2); viruses in these clades are antigenically distinguishable.
- Antigenic analyses of A(H3N2)v viruses, the cause of zoonotic infections in the USA, indicate that these viruses are antigenically distinct from seasonal A(H3N2) viruses.
Influenza virus characterisation - Summary Europe, September 2021
22 Oct 2021 - This is the 10th and final report for the 2020-2021 influenza season. As of week 39/2021, only 1 276 influenza detections across the WHO European Region were reported to TESSy.
Cryptosporidiosis - Annual Epidemiological Report for 2018
5 Oct 2021 - For 2018, 20 European Union/European Economic Area (EU/EEA) countries reported 14 299 cryptosporidiosis cases, of which 14 252 were confirmed.
Avian influenza overview May – September 2021
30 Sep 2021 - The 2020–2021 avian influenza epidemic with a total of 3,777 reported highly pathogenic avian influenza (HPAI) detections and approximately 22,900,000 affected poultry birds in 31 European Countries appears to be one of the largest HPAI epidemics that has ever occurred in Europe.
