#H5N5 #Birdflu virus found in polar #bear in #Europe for first time, on #Svalbard , https://www.reuters.com/business/healthcare-pharmaceuticals/bird-flu-found-polar-bear-europe-first-time-svalbard-2026-05-19/

The Norwegian Veterinary Institute said in a statement it had also detected bird flu in a dead walrus on Svalbard, which is roughly halfway ⁠between the North Pole and mainland Europe.

“These findings are part of the ongoing spread of highly pathogenic avian influenza in Europe, where the virus is increasingly being detected in mammals. In recent years, it has also expanded into new areas, including the Arctic, where it may impact vulnerable wildlife populations and fragile ecosystems.”

Influenza A virus genome sequencing of BAL specimen... confirmed HPAI H5N5 virus, Eurasian lineage clade 6 (EA6). Viral segment sequences had approximately 99% identity to contemporary HPAI A(H5N5) viruses without evidence of reassortment.
