The paper tracks the evolution of Avian Influenza H5N1 genotype EA-2024-DI across three epidemic waves, showing changes in transmission patterns and increased mammalian host adaptation.

This paper tracks the outbreak of HPAIV H5N1 euBB in black-headed gulls and common terns in Germany, showing multiple incursions, high mortality, and population declines.

The paper identifies H5N1 avian influenza virus as the cause of a mass mortality event in Eurasian cranes in Germany in 2025, linked to their social behavior.

This study investigates H5N1 clade 2.3.4.4b virus infection in calves and lactating cows, finding that mammary gland infection causes severe mastitis and reduced milk production, with transmission likely via milk rather than respiratory routes.
