In March a farm worker who reported no contact with sick or dead birds, but who was in contact with dairy cattle, began showing symptoms in the eye and samples were collected by the regional health department to test for potential influenza A. Experts have now confirmed the first case of highly pathogenic avian influenza transmission from a mammal (dairy cow) to a human.
I just don’t get why transmission to humans is considered a question. Transmissions to mammals is happening. We are mammals. We aren’t special. We need to stop acting like we’re something different so leopards don’t eat our stupid faces.
I don’t question that the quoted person knows what they are talking about, but that quote perpetuates the idea that H5N1 is a long shot when we already have people playing freedom about milk.
there are hundreds of diseases that exist in mammals like dogs and bats which do not transmit to humans. when a new one does, it’s a big deal, all the time, every time. especially one that has crossed the taxonomic bridge from avians to mammals. for fucks sake.
Of course it’s a big deal. But H5N1 has transmitted already between multiple mammals (https://www.aphis.usda.gov/livestock-poultry-disease/avian/avian-influenza/hpai-detections/mammals , but you already know that stuff I think).
The phrasing in the quote, in my opinion, gives countless people the wrong idea of human uniqueness in this situation.
giving countless people the idea that this is a very big deal, is dangerous, and something to pay attention to, what is it now, 4 years after the start of a worldwide pandemic which saw millions of lives simply wiped off the board, and the global economy brought to a standstill, is precisely the message which should be broadcast. we were not ready for COVID, and we are STILL not prepared for the next one, because it costs the wrong people, too much time, effort, and money to be ready.
Mammals are not identical and there are a ton of diseases that do affect multiple species and a lot more that don’t.
Opossums rarely, if ever, get rabies. Bats tend to get diseases without suffering from them, but are great incubators for diseases to mutate so they can spread to other mammals. Feline lukemia is extremely contagious between cats, but has never spread to humans.
It is not that humans are special, but that diseases are not universally transmitted between species.
This is a big deal because the bird to cow to human transmission doesn’t have a precedent. No scientist who studies disease thinks transmission is impossible, since diseases can mutate.
You just picked a mammal with one of the most unique immune systems and one that is a completely different class of mammal of which very few exist tbf. Many diseases can only affect a very small handful of even quite related species though. There are diseases that affect some apes but not others.
I fully agree, but I also grew up around religion, so… humans gonna get their face eaten.
There have been almost 1000 confirmed H5N1 cases in humans over the past 20 years, and over that time it’s infected many different mammals. What’s different this time is the virulent cattle-to-cattle transmission happening in the US. A human catching it from close contact with an infected animal is not unusual
