Beyond the noise #41: h5n1 influenza virus is unlikely to become a human pandemic july 15, 2024 in this episode dr. offit gives his thoughts about whether h5n1 influenza virus will cause a human pandemic. A major outbreak of a new strain of bird flu — formally named influenza a virus subtype h5n1 — has since killed millions of wild birds and infected poultry, dairy cattle, domestic cats and a small number of humans. in the united states, four people have contracted the virus. the most recently confirmed case, a dairy worker in michigan, was. The mutation’s first recorded appearance was in the virus causing the 1918 flu. “that pb2 was so good that it has stuck in every human influenza virus until the 2009 swine flu pandemic,” says imperial college london virologist tom peacock. whatever path the virus hits upon, h5n1 needs an altered pb2 to become a human pathogen.

Cbc news talked to several researchers, including those studying h5n1 now and others who've followed influenza trends for decades, to help unpack the crucial unanswered questions around this virus. This is the core concern around pandemic potential of zoonotic influenza a viruses. influenza a viruses mutate rapidly, so the central concern right now is whether this h5n1 virus has evolved a mechanism to transmit between cows—which it appears it has—and whether intensified transmission among cows increases human exposure.
