This diagram depicts the origins of the H7N9 virus from China and shows how the virus’s genes came from other influenza viruses in birds. Influenza A H7N9 as viewed through an electron …

The highly pathogenic influenza A virus subtype H5N1 is an emerging avian influenza virus that is causing global concern as a potential pandemic threat. It is often referred to simply as "bird flu" …

The avian influenza A virus (AIV) is naturally prevalent in aquatic birds, infecting different avian species and transmitting from birds to humans.

The genetic structure of H5N1, a highly pathogenic avian influenza virus (influenza A virus subtype H5N1), is characterized by a segmented RNA genome consisting of eight gene …

Avian influenza (AI) is a zoonotic viral endemic disease that affects poultry, swine, and mammals, including humans. Highly pathogenic avian influenza (HPAI) is caused by influenza type A...

Here we review the pathology of H5N1 avian influenza reported in postmortem and clinical studies and discuss the key pathogenetic mechanisms. Specifically, the virus infects isolated …

Reservoirs and interspecies transmission events of influenza A viruses and the subtypes involved in these events. Aquatic wild birds represent the natural reservoir of influenza A...

Transcription and replication of the influenza virus RNA genome is catalyzed by the viral heterotrimeric RNA-dependent RNA polymerase in the context of viral ribonucleoprotein …

Dec 20, 2024 · Most avian influenza A viruses are low pathogenic and cause few signs of disease in infected wild birds. In poultry, some low-pathogenic viruses can mutate into highly …

1 day ago · Mild forms of avian influenza (known as low pathogenic avian influenza, or LPAI) are routinely found in wild birds and don’t cause serious illness. From time to time, a mild strain …
