   Jan 24, 2023 · Sequenced virus samples from four mink show several changes compared with the bird virus, including T271A, a mutation in the gene for an enzyme, polymerase. The change, also seen in viral samples from other infected mammals, is known to help H5N1 better replicate in mammalian tissues.

   Does bird flu spread more easily between birds and marine mammals?

   • FRIDAY, March 1, 2023 (HealthDay News) -- Bird flu has mutated to spread more easily between birds and marine mammals, increasing the potential risk to humans, a new study warns. Four sea lions, one fur seal and a tern found dead in Argentina all tested positive for the avian influenza virus H5N1, researchers report.

   Could bird flu jump into humans?

   • The risk that bird flu could jump into humans is potentially rising, given that it is now passing between marine mammals and birds. The highly pathogenic avian influenza virus H5N1 has adapted to spread between birds and marine mammals, posing an immediate threat to wildlife conservation.

   Is bird flu causing a large-scale infection in other mammalian species?

   • And the findings hold a warning: The virus, called H5N1, may similarly transform to cause large-scale infections in other mammalian species, including people. The bird flu virus is responsible for an ongoing outbreak in dairy cows in the United States. Since March, it has been detected in cows in 11 states, and in wastewater from several others.

   Did H5N1 jump from sea mammals back into birds?

   • In fact, Dr. Uhart and her colleagues found evidence suggesting that the virus jumped from sea mammals back into birds — an unwelcome development, because infected birds can disperse the virus wherever they migrate. The researchers found H5N1 in the windpipes, lungs and brains of carcasses of sea mammals.

   Where did the H5N1 bird flu come from?

   • Dec. 2021 The H5N1 bird flu virus is detected on a farm in St. John’s, Newfoundland, and in a sick wild gull nearby. Hundreds of birds on the farm died, and the rest were culled. It is the first detection of the virus in North America. Migrating shorebirds may have carried the virus from Europe to Newfoundland through Iceland or Greenland.
