The H5N1 bird flu virus has recently been detected in Alaskan wildlife, primarily affecting species like geese, ducks, and eagles. No human cases have been reported, but it poses a significant risk to domestic poultry flocks.

Case counts for Oropouche virus are still low but rising dramatically. What's going on? And then there's a study that raises the possibility that insect bites aren't the only way the virus can spread.

Chukchi Sea polar bears show increased exposure to pathogens like canine distemper virus and Toxoplasma gondii, potentially due to changes in their diet and extended time on land.

In 2023, tularemia occurred in a wildlife volunteer after exposure to a deceased, infected harbor seal, the first known report of tularemia acquired through contact with a marine mammal, and the first detection of F. tularensis in a marine mammal.

As bird flu cases go underreported, health officials risk being slow to notice if the virus were to become more contagious. A large surge of infections outside of farmworker communities would trigger the government’s flu surveillance system, but by then it might be too late to contain.

The article discusses the rise in tick-borne illnesses in Canada, highlighting a case of Powassan virus and the challenges in diagnosis and treatment due to limited awareness among healthcare providers.

New U.S. regulations require all dogs entering from abroad to be at least 6 months old and microchipped to mitigate rabies risks.

For nine years, Alaska health officials have been aware of an unusual virus causing rare, relatively mild illnesses in the Fairbanks area. But a recent case in another part of the state — this one resulting in a man's death — has brought new attention to the Alaskapox virus.

More than a dozen states, including several in the Pacific Northwest, are reporting outbreaks of a new respiratory illness. There have also been increases in canine respiratory illness cases at a clinic in Southeast Alaska and another in Southcentral, but there’s no indication yet if those were due to the mystery illness.

Health officials in Sanikiluaq, Hudson Bay, warn against consuming fermented meat due to a suspected botulism outbreak and urge vigilance for related symptoms.

Countries including South Korea, Japan, Australia, and the Phillipines have halted imports of Swedish pork following the recent discovery of African swine fever. 7 dead wild boars have now been confirmed infected.

The R/V Sikuliaq is a familiar sight in the Port of Nome. The ice-breaking research vessel is owned by the National Science Foundation and operated by the University of Alaska Fairbanks. This year, while the vessel is out at sea it will be collecting water that could signal whether a bloom is occurring.

No one knows how many birds are infected with avian influenza along the coast of Finnmark. In Vadsø, seagulls sit next to dozens of dead birds.

The current outbreaks of avian influenza (also called “bird flu”) have caused devastation in animal populations, including poultry, wild birds, and some mammals, and harmed farmers’ livelihoods and the food trade. Although largely affecting animals, these outbreaks pose ongoing risks to humans.

People spread Covid-19 to wild white-tailed deer more than 100 times in late 2021 and early 2022. The infection circulated widely in the deer population in the United States, and in at least three instances, researchers suspect the virus was passed between deer where it picked up unique genetic changes and then re-infected humans.

This rural part of the island of Oahu is not connected to city sewers — and waste from toilets, sinks and showers is mostly collected in hundreds of pits called cesspools. Rising seas are also pushing groundwater closer to the surface, allowing cesspool effluent to mix with the water table and flow into the ocean.

Scientists say they found the virus in one of five submitted chicken meat samples that the cats ate.

The highly pathogenic disease circling the globe stands out for its effects on wild birds, and experts say Alaskans should be on the lookout for cases.

Governments should consider vaccinating poultry against bird flu, which has killed hundreds of millions of birds and infected mammals worldwide, to prevent the virus from turning into a new pandemic, the head of the World Organisation for Animal Health (WOAH) said.

When you see a wild bird such as a duck or seagull, think bird flu. Because it’s actually more likely than not they’re infected with the virus. And many species of wild birds are asymptomatic, meaning that they don’t show any symptoms.
