Surveillance reveals four novel highly pathogenic avian influenza genotypes in Germany, indicating ongoing viral reassortment and strain displacement.

Four new highly pathogenic avian influenza genotypes emerged in November 2023 after reassortment with low pathogenicity precursors, replacing genotype BB, which had dominated in Europe since 2022.
