Iceland reported an outbreak of H5N5 avian influenza in a small meat turkey flock in the southern region of the nation.  Concurrently, a similar isolate was identified in a seagull near Reykjavik and in two other birds in the north and southeast quadrants of the nation.

H5N5 has also been isolated from farms in northern England and Norway, respectively.

It would appear that H5N5 is disseminated by migratory marine birds in their westward movement. In 2022 changes in migratory patterns, possibly associated with global warming allowed migratory birds to transmit H5N1 from Scandinavian nations westward via Iceland and Greenland to the province of Labrador. This established a new route of introduction to the North American continent.  Obviously, surveillance of wild birds and commercial poultry in coming months will indicate whether H5N5 will emerge as a strain of commercial significance.
