It is the same as those who slaughtered said that they wrote something about the meat that was killed for the first time: "We will leave it in our hands."

"If no one is watching, we don't know what's going on."

With Antarctica added to the list, bird flu is officially endemic to every continent except Oceania.A recent study by Erasmus MC of the Netherlands and the University of California, Davis confirmed that disturbing story.

A team of researchers has finally shown that more than 50 Antarctic terns died in the summer of 2023 and 2024 due to the highly pathogenic H5N1 bird flu virus.They published the study in the journal Scientific Reports and contextualized its findings in a press release.

Skuas are relatives of seagulls and play an important role in cold environments.They act as scavengers in the ecosystem, meaning an infectious skua can spread bird flu far and wide.

During expeditions to the South Shetland Islands, the northern Weddell Sea, and the Antarctic Peninsula, the team tested wildlife samples and confirmed H5N1 infections in each location.While bird flu had been found before, this study was the first to confirm that the virus was the cause of animal deaths.

Although other animals, such as feathers, are infected, their death does not follow.

"As the expedition progressed, it quickly became apparent that the skuas were suffering greatly," said UC Davis senior author Ralph Vanstreels.

Vanstreels painted a disturbing picture of a "crisis in animal suffering" with the virus causing birds to drop out of the air, swim and walk aimlessly as the virus attacks the brain.

Why is the spread of bird flu important?

H5N1 was first identified on a Chinese goose farm in 1996 and has since spread globally in a pattern that has puzzled scientists.

"We let the virus slip through our fingers when it first appeared in the poultry industry," said lead author Thijs Kuiken of Erasmus MC."Once it enters the wild bird population, we lose the ability to control this virus."

Bird flu has a devastating effect on almost every corner of the world.In the United States, mega-farms have been affected, and this has affected both humans and animals.The virus is highly adaptable and has been shown to change when the host is human or cattle.

There is also concern that cats can transmit the disease to humans on a large scale.

Closer to the study, the decline of the skuas population could create even more problems for the already threatened Antarctic region.There are fears that he might become infected in the future.

What to do about bird flu in Antarctica?

The researchers called for improved international surveillance and prevention measures to better monitor bird flu in Antarctica.

"Everything shows that this virus is spreading again. If no one is watching, we won't know what's happening," Kuykin concluded.
