# Norway Reports Europe’s First Bird Flu Case in a Polar Bear

Norwegian authorities say H5N5 bird flu was found in a polar bear in Svalbard, marking the first documented case of avian influenza in the species in Europe.

Norwegian authorities have announced what they describe as Europe’s first documented case of avian influenza in a polar bear. The virus was detected in the Svalbard region in the Arctic, a remote archipelago far north of mainland Norway, according to the AFP report carried by GMA News Online.

The case involved a male bear about one year old, and officials said the H5N5 variant was also detected in a walrus found dead in mid-May on the same icy archipelago. The Norwegian Veterinary Institute said samples from the two animals carried evidence of the virus. The governor of Svalbard separately said the presence of the virus in brain samples from both animals was consistent with the hypothesis that it was very likely the cause of death.

That finding matters for two reasons. First, it extends the geographic reach of highly pathogenic bird flu into the Arctic. Second, it shows the virus is showing up in mammal species in ways that raise concern for vulnerable populations and ecosystems. The Veterinary Institute’s bird flu coordinator, Ragnhild Tonnessen, said the result fits a broader trend in which highly pathogenic avian influenza viruses are increasingly being detected in mammals in Europe.

The source packet also places the case in a wider international context. A walrus that died of bird flu had already been found in Svalbard in 2023, and the virus was documented in a polar bear that died in Alaska that same year. Those comparisons suggest the new Norwegian case is unusual for Europe but not isolated in the global spread of the virus among mammals.

The article also cites World Organisation for Animal Health data showing that 140 million animals died or were culled because of avian influenza between January 2025 and March 2026 in nearly 70 countries. That figure shows the scale of the broader outbreak, even though the overall toll was still below a peak in 2021-2022. The key public-health concern in the report is not just animal mortality but the spread of the virus into new species and regions.

Even with the limited evidence available, the core news value is strong: a polar bear in Europe has now been added to the list of mammalian hosts affected by bird flu. The Arctic setting makes the finding especially notable, because it suggests the virus has reached one of the planet’s most remote ecosystems.

The report does not claim this case changes human risk overnight. It does, however, show that avian influenza continues to move in ways that scientists are still tracking closely. In a place as ecologically sensitive as Svalbard, a single case can carry significance beyond the animal itself.
