External quality assessment scheme for detection, isolation and characterisation of influenza viruses for the European Reference Laboratory Network for Human Influenza – 2015
In June and July 2015, an influenza virus rapid detection, isolation and characterisation external quality assessment (EQA) exercise was held for European influenza reference laboratories. This was the fourth rapid detection, isolation and characterisation EQA panel distributed by the European Reference Laboratory Network for Human Influenza.
As with previous panels, the performance of laboratories in the rapid detection component of the exercise was encouraging. Thirty-four of the 38 laboratories achieved top marks, with 92% of laboratories receiving a maximum score. As expected, results from the antigenic characterisations reflected the difficulties that have been described with A(H3N2) subtypes. The subgroup 3C.2a isolate proved challenging, with only nine of the 26 laboratories reporting the correct strain characterisation (Figure 9A). Overall virus characterisation results, based on the combined results from genetic and antigenic characterisation, have improved over the last three EQA panels.

Avian influenza overview December 2022 – March 2023
13 Mar 2023 - Between 3 December 2022 and 1 March 2023 highly pathogenic avian influenza (HPAI) A(H5N1) virus, clade 220.127.116.11b, was reported in Europe in domestic (522) and wild (1,138) birds over 24 countries. An unexpected number of HPAI virus detections in sea birds were observed, mainly in gull species and particularly in black-headed gulls (large mortality events were observed in France, Belgium, the Netherlands, and Italy).
Zoonotic influenza - Annual Epidemiological Report for 2021
10 Mar 2023 - No human infections with avian influenza virus were reported in the European Union/European Economic Area (EU/EEA) in 2021. Sporadic human infections with avian influenza virus A(H5) (including A(H5N1) and A(H5N6)), A(H9N2) and A(H10N3) infection were reported globally in 2021.
