The primary transmission pathway for bird flu remains through contact with infected birds. These animals can shed the virus through various bodily fluids including saliva, nasal secretions, and feces.

Transmission chains were reconstructed using custom genomic analysis software. H5N1 clade 2.3.4.4b genotype B3.13 influenza A virus was confirmed in milk samples with limited detection in nasal swabs.

Recent viral mutations have shown avian influenza’s adaptability to mammalian hosts, prompting infectious disease, animal health, and environmental health experts to remain vigilant.

Cornell scientists have uncovered more about the 'spillover' of the highly pathogenic avian influenza (HPIA) H5N1 clade 2.3.4.4b virus, which is characterized as a "significant increase in the ...

A single mutation in the surface protein of the highly pathogenic avian influenza (HPAI) H5N1 influenza virus could allow for easier human transmission.

On February 19, Tulane University reported that a new variant of the H5N1 strain of avian influenza, also known as bird flu, was found in cows and a dairy worker. But that's not the only bad news.
