Numbers of raptors screened for influenza A viruses (IAV) and testing positive for gs/GD highly pathogenic avian influenza viruses (HPAIV). The proportion of HPAIV-positive birds is given for the retrospective surveillance across the whole of Germany between 2016–2022 (A) and nestlings and non-nestlings (B), sampled within the prospective-regional sampling approach in Mecklenburg-Western Pomerania (MWP), a Federal State in the Northeast of Germany (2021 and 2022).
