Cows at two Texas dairy farms have contracted bird flu, marking the first known instance of the disease in livestock, amidst recovery from devastating wildfires.

Samples taken from a white-tailed eagle found dead on a skerry near Barðaströnd in the Westfjords in mid-September tested positive for a severe bird flu virus of the strain HPAI H4N5. An eider duck that was found dead in Ólafsfjörður, West Iceland recently was infected with the same strain of bird flu virus. The strain has not been detected in Iceland before and is not common.

H5N5, a new subtype of the avian influenza virus, has been found in birds and raccoons in P.E.I. It's closely related to the H5N1 virus that's caused mass death among seabird populations in Atlantic Canada.

Pathologists say they’ve detected cases of the virus, commonly known as the bird flu, in three cats in Nebraska.

Three cases of H3N8 detected in China since 2022 as WHO says strain doesn’t appear to spread easily between humans. First case resulting in death occurred in China.
