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.
Yes, but also happens naturally to some extent as well.
It happens a lot less when you don’t cramp billions of animals in extremely close quarters
While I agree. It is really dependent on the pathogenicity of whatever it is.
I do not think we should cramp animals together for food, sadly, which is done now.
Farming could be much more humane, and I hope it becomes that. I totally agree with your point though.
