On Jan. 9, 2024, biologists in Alaska have confirmed the first case of a polar bear dying after contracting avian flu. The state veterinarian’s office announced in December that a polar bear (Ursus maritimus) had died from the H5N1 strain of highly pathogenic avian influenza.

Biologists believe the bear, found in the North Slope town of Utqiagvik in October, contracted the virus from scavenging on infected birds.

The virus has claimed red foxes (Vulpes vulpes), black bears (U. americanus) and brown bears (U. arctos), in addition to wild birds—particularly waterfowl—and domestic poultry in the state since it was first discovered there in April 2022.
