Annual report on surveillance for avian influenza in poultry and wild birds in Member States of the European Union in 2022
Abstract All European Union (EU) Member States (MSs) are required to implement surveillance for avian influenza (AI) in poultry and wild birds and (i) to notify the outbreaks, when relevant and (ii) to report the results to the responsible authority. In addition, Iceland, Norway, Switzerland and the...

The present report summarises the results of the surveillance activities carried out in MSs, Iceland, Norway, Switzerland and the United Kingdom (Northern Ireland) in 2022. Overall, the 31 reporting countries (RCs) sampled 22,171 poultry establishments (PEs) during the 2022 surveillance activity: 18,490 PEs were sampled for serological testing and 3775 were sampled for virological testing. Some PEs were therefore sampled for both type of analytical methods. Out of the 18,490 PEs sampled for serological testing, 15 (0.08%) were seropositive for influenza A(H5) viruses. Out of the 3775 PEs sampled for virological testing, 74 PEs (1.96%) were positive to the virological assay for influenza A(H5) viruses. Seropositive PEs were found in four RCs (Belgium, Poland, Spain and Sweden) and as in previous years, the highest percentages of seropositive PEs were found in PEs raising breeding geese and waterfowl game birds. Out of these 15 seropositive PEs, 3 also tested positive by polymerase chain reaction (PCR) for influenza A (H5) viruses – 2 for highly pathogenic avian influenza virus (HPAIV) and 1 low pathogenic avian influenza (LPAI) (H5N3). In relation to the virological surveys, 10 RCs (32%) out of the 31 reported the detection of A (H5) viruses in 74 PEs, covering 12 different poultry categories.
