It appears that highly pathogenic avian bird flu has jumped to mammals. I remember the Swine flu of 2008-2009 that originated in Mexico. I got infected with it when I lived in Texas before they knew what it was. I almost died at home alone out in the woods, too weak to turn over in bed or dial 911.
The previous bird flu, the one before this one, was usually found in free range home flocks where people had mixed chickens with water fowl. The ducks went swimming with the wild water fowl and brought it home to the henhouse

It's always had the ability to infect mammals. Well, at least since 1998, when 18 people died from HPAI.
This abstract was from 2009:
In recent years, there has been an increase in outbreaks of highly pathogenic avian influenza (HPAI) in poultry. Occasionally, these outbreaks have resulted in transmission of influenza viruses to humans and other mammals, with symptoms ranging from conjunctivitis to pneumonia and death. Here, the current knowledge of the determinants of pathogenicity of HPAI viruses in mammals is summarized. It is becoming apparent that common mechanisms exist across influenza A virus strains and subtypes, through which influenza viruses adapt to mammals and gain or loose pathogenicity.
From 2013:

Luck said "So you caught the bird flu? Any idea how you caught it? How long were you sick and what were the symptoms?"
No, that was the the swine flu H1N1 epidemic of 2009. The virus jumped to humans on Mexican farm workers. I probably caught it Dec. 2008 at the Texas hospital where I was a nurse. Symptoms were respiratory, with muscle aches, fever and weakness so pronounced I couldn't even turn over in bed. I've had covid and this was much worse.

(Update)
I guess by now people have heard about this. The H5N1 Bird flu from last year that caused massive depopulation of poultry farms all over the world is still around. Now it's spread to dairy herds first in the Texas panhandle, then New Mexico, Kansas, Minnesota, and Idaho. The infected cows are 10% -20% of affected mil king herds and only affects middle age lactating cows. They have fever, milk production drops, milk becomes thickened like colostrum, and reduced rumen activity. Sickness peaks at 5 days, they recover in 2 or 3 weeks. None have died.
At a Minnesota farm they had to depopulate the ducks and chickens because of an H5N1 outbreak and their goats were lose in the same pens. 10 baby goats died because it had jumped to mammals. Well, now it has spread to another mammal, a dairy worker in Texas. His only symptom so far was conjunctivitis (red eyes) and they quickly gave him Tamiflu shots and put him in isolation. The raw milk crazies are now up in arms because the USDA and CDC says the US milk supply is safe because commercial milk is pasteurized and pasteurization kills germs and viruses.

Why would they be upset about a statement of fact?

Because without gain of function research, none of this would be possible.

The most astute observation, I heard about the avian flu was that it dropped the cattle futures. I wonder who was short cattle at the time of the announcement.

Heard a very short blurb on the radio this morning that the scare of the bird flu that was in several herds in different states,, has been studied under a couple tests, and it does NOT appear in the milk as originally speculated.......didn't manage to catch it all... anyone else heard anything?

Ok so in have a beef herd , what should i watch for in my animals and what's the treatment if something does pop up. I have heard different things so was wondering. I know this thing will get completely blown out of proportion but I want to stay in front of it.

Will get? Already has. I have seen news of it posted, then reposted multiple times cross every segment of everywhere and "lawd sav us' everywhere.

I don't think it is being looked at in beef cattle because we do not see the same "drop in production" and loss of appetite as in dairy cattle, since it is very "observeable" since the obvious drop in milk is associated with drop in feed intake... How do you measure the drop in beef cattle intake out on grass and are maybe just not eating as much for a few days? The dairy cattle "get over it" .... something like we get feeling crappy with a "flu" and IN MOST CASES... after a few days or week or so, our body fights it off and we gradually get back to normal... seems like the dairy cattle pretty much do the same thing... except the drop in milk production is very noticeable since we are milking twice a day... and the prescribed amount of feed put out for daily consumption suddenly results in feed being left in the bunk...
Right or wrong, dairy cattle are closely monitored and feed intake and milk output is easily measured and any deviation is quickly noticed... so these things are very quickly looked at with the reasons for the changes needing to be addressed immediately. You just don't have that kind of "handle" on beef cattle because you are not measuring their daily intake so closely.

So there's no runny nose, coughing, stiffness or being lethargic.

Yes, all of those things MIGHT occur... but most show very little signs of that, and honestly, how many people see their beef cattle that often to notice those differences. Unless you see a cow that is "off" and then have a vet do a blood test ( I think that it can show up in blood... but whatever they do to test it besides milk) then it is highly unlikely you are going to know if they have it. It is mostly showing up in the milk and in a drop in feed consumption... and they seem to get over it in about 2 weeks from the last reports I have read. I'm not a vet, but the dairy farmers I have talked to here recently are not going into panic mode over it in this area. Our vet did preg checks last week on a group of cows and he said it is not on the top of their list to be worrying about with the dairy herds he does regular herd checks for and no beef cows are on their radar. We have a much bigger problem here with is Longhorn tick disease ...
theileria... which causes unthrifty cattle, abortion and can kill the cattle if severe. These ticks are a major problem...especially along the interstate routes is seems... and then cattle taken home to other areas... found a "normal tick" on the scotum of bull that just went through his BSE the other day....

Heard an update that the HPAI that had been found in cattle and milk was rendered completely harmless in pasteurized milk. Studies had been done and that what partial particles could be detected were not able to carry this virus since they were not viable when pieces were put under a microscope and tried to "grow" in the lab. The pasteurization killed any ability of the virus to survive so milk is considered perfectly safe to drink.
