Wild aquatic bird populations have long been considered the natural reservoir for influenza
A viruses with virus transmission from these birds seeding other avian and mammalian …

We reviewed information about mammals naturally infected by highly pathogenic avian
influenza A virus subtype H5N1 during 2 periods: the current panzootic (2020–2023) and …

Pandemic influenza virus has its origins in avian influenza viruses. The highly pathogenic
avian influenza virus subtype H5N1 is already panzootic in poultry, with attendant economic …

Highly pathogenic H5N1 influenza A viruses have spread relentlessly across the globe
since 2003, and they are associated with widespread death in poultry, substantial economic …

Avian influenza H5N1 virus is known to cross the species barrier and infect humans and
felines. We report a fatal H5N1 infection in a dog following ingestion of an H5N1-infected …

Free‐roaming cat populations have been identified as a significant public health threat and
are a source for several zoonotic diseases including rabies, toxoplasmosis, cutaneous larval …

The environmental drivers of influenza outbreaks are largely unknown. Despite more than
50 years of research, there are conflicting lines of evidence on the role of the environment in …

In this investigation, we used a combination of field-and laboratory-based approaches to
assess if influenza A viruses (IAVs) shed by ducks could remain viable for extended periods …

Adaptation of influenza A viruses to a new host species usually involves the mutation of one
or more of the eight viral gene segments, and the molecular basis for host range restriction is …

Highly pathogenic avian influenza viruses of subtype H5N1 are remarkable because of their
expanding non-avian host range and wide tissue tropism. They have caused severe or fatal …
