Bird flu virus shows mutations in first severe human infection in US, CDC says (www.theguardian.com)

submitted 1 day ago by MicroWave to c/news

27 comments fedilink hide all child comments

Summary

The CDC identified rare mutations in the bird flu virus from the first severe U.S. human case, found in a Louisiana resident over 65 with severe respiratory illness.

The mutations, located in the hemagglutinin (HA) gene responsible for cell attachment, differ from those in local backyard flock samples and align with severe cases seen abroad.

The patient was infected with the D1.1 genotype, recently found in U.S. wild birds and poultry, not the B3.13 genotype seen in humans and livestock elsewhere.

The CDC states no person-to-person transmission occurred, and public risk remains low.

This thing is on the way, dammit. I've been seeing a lot of reports on its spread, where they say the udders of cows have receptors for both human and bird flus, and if both are present they can exchange genes and mutate a lot. Only a matter of time for human to human. And it'll likely be a lot more deadly than COVID. 😢

[–] Regrettable_incident 3 points 17 hours ago

Yeah, something like this is pretty much inevitable. We have large, dense populations of humans living in close proximity with animals. Stuff of going to jump the species gap, and yeah it'll probably be much worse than COVID, which was not that severe in terms of death rates.

Ah good, I really could use another two years of working from home.

We should have culled all these cows, and kept culling them until nobody and nothing tested positive. And done it all a year ago. But apparently that was too hard, and now it's really just luck whether this becomes the next global catastrophe.

not too hard, it's just less profits now for the animal owners and more profits later for pharma and big tech.

[–] Podunk 21 points 1 day ago (1 children)

We should have vaccinated our poultry flocks instead of letting it proliferate for decades. But we had to protect our export market.

Its in the wild populations so heavily now there is not stopping it with culls of any animal species.

[–] logi 4 points 17 hours ago (2 children)

It has been in wild birds world wide for years now. The birds having bird flu is not an American problem. The cows somehow all having bird flu is all yours though. Thankfully cows don't fly and don't migrate long distances.

[–] [email protected] 2 points 11 hours ago

Thankfully cows don’t fly and don’t migrate long distances.

Naturally, cows don't migrate long distances. However humans on the other hand, will gladly help cows travel long distance.

[–] Podunk 2 points 11 hours ago (1 children)

Its all a problem. But you missed the important part.

We didnt vaccinate our domestic flocks because it would hurt our export market. We allowed high population sites to become reservoirs for the bird flu, instead. when the virus was detected, we torched the whole flock. But it always spread because we were not willing to remove a vital link in its spread through vaccine protocols. Now it is too big of a problem, and we get multiple spillover events.

There is a vaccine for birds, and we didnt use it. There is no vaccine for cattle.

[–] logi 1 points 7 hours ago

Sure, all of that should have been done. I'm just commenting on

It's in the wild populations so heavily now

It always was and it's doing great damage to wild birds throughout the world. Regardless of US paultry farms. So you could have had healthier domestic birds, but there is nothing you could have done to avoid the virus being present in the environment.

We've had one Trump pandemic, but what about second Trump pandemic?

[–] Zahille7 26 points 1 day ago (1 children)

At least this one's kicking off right as he's about to start, instead of 2.5 years into his presidency.

Now we can only hope if it gets out of hand like last time, he'll be just as stupid and catch it again. And not go to the ER.

[–] CitizenKong 13 points 1 day ago (3 children)

Bird flu is a lot more deadly, a death sentence for someone his age and (lack of) fitness.

[–] [email protected] 2 points 19 hours ago

And COVID fucked up many people's respiratory/immune systems. I got asthma because of it.

[–] [email protected] 10 points 1 day ago

Don't get my hopes up like that

[–] ATDA 1 points 19 hours ago (1 children)

COVID nearly got him before the shooters tried. I remember him looking pretty shit there when he was 'totally fine' in that hospital.

[–] CitizenKong 1 points 9 hours ago

Yeah, he might also still have effects from it. His voice is a lot weaker and hoarse now and Covid can also quicken mental degredation, since it attacks nerves in the brain.

[–] jaybone 26 points 1 day ago

Soon RFK will be in charge of the CDC, then you won’t hear about any of these so-called reports.

[–] [email protected] 25 points 1 day ago (1 children)

Yes we Already had one bird flu but how about second bird flu?

[–] Knock_Knock_Lemmy_In 2 points 16 hours ago (1 children)

The first was bat flu.

[–] [email protected] 1 points 12 hours ago* (last edited 12 hours ago)

O I thought this a mutation of the current bird flu. D1 vs b3

[–] EmpathicVagrant 14 points 1 day ago (1 children)

Rare mutations sure must be pretty common if I’ve heard this phrase so often.

[–] alleycat 52 points 1 day ago (1 children)

Rare becomes likely if you roll the dice often enough.

[–] EmpathicVagrant 11 points 1 day ago (2 children)

Exactly. Common Uncommon Rare Epic Legendary

Basically a coin flip sounds about right. I’ll call it coinflu

[–] [email protected] 8 points 1 day ago

But they are still rare in terms of number of virus bodies generated daily by viral reproduction multiplied by number of infections.

If they weren't rare, these infections would get deadly mutations in hours, not weeks or months.

[–] MegaUltraChicken 2 points 1 day ago

Legendary mutations turn the virus orange.

[–] some_designer_dude 2 points 1 day ago

Nothing to see here. Back to work, everyone! Just eat some horse tranqs and wash it down with some bleach and you’ll be strong as an ox.

Americans, probably
