This study shows that the mammalian-adaptive PB2-E627K mutation in H5N1 HPAIV maintains viral fitness in avian hosts, increasing zoonotic risk.

This study shows pigeons are not easily infected by H5N1 clade 2.3.4.4b virus and cannot transmit it to other birds or chickens.

This study investigates the factors driving the shift in dominance from H5N8 to H5N1 HPAIVs in wild birds, finding that viral pathogenicity and immune responses differ between subtypes.
