Cats with bird flu? The threat grows

The global H5N1 avian flu outbreak, already devastating wild birds and poultry, keeps spreading to mammals, bringing it one step closer to a potential human outbreak.

Of course, since the coronavirus pandemic taught us the importance of responding early and aggressively to outbreaks …

Sorry, I’m joking. We don’t seem to have learned much from the Covid outbreak, and it’s not funny.

Not enough has been done about an out-of-control H5N1 outbreak at fur farms in Finland or a mystery outbreak among domestic cats in Poland.

Finland, one of Europe’s biggest fur producers, is battling outbreaks among its captive minks, foxes and raccoon dogs — species that scientists warn have been identified as more likely to evolve a variant that can infect people, leading to a human outbreak.

Even the Finnish Food Authority, in its announcement of animals being culled, noted that minks are susceptible to both human and avian influenza. If one animal is infected by both, the viruses can mix genes and give rise to an avian flu that can infect humans. Fur farms in Finland, however, aren’t being closed. Instead the Finnish Wildlife Agency allowed fur breeders to kill wild birds near their farms in large numbers. The Agency told me the killings were authorized “to prevent contacts between infected birds and animals at fur farms,” but scientists point out this is the wrong approach and likely futile — and more fur farms in Finland have since announced further outbreaks.

Meanwhile, officials said a sizable outbreak of H5N1 among pet cats in Poland this summer killed at least 29 animals, though cat owners have compiled lists with as many as 89 sick animals. The outbreak has many unusual features that make it especially concerning, and yet there still hasn’t been an explanation of how exactly it happened or a vigorous investigation. [Continue reading…]
