I’m sure that this seems obvious to you, but it’s not clear to me… are you saying that human to human transmission isn’t worth worrying about, even if the virus mutated to be more infectious between humans?

Having a quick read, it seems like infections in humans range from unnoticeable to very severe, so I guess it’s going to be a question of the ratio between severe and mild cases, which is unknown level given that we would need a mutation before it became relevant.

Did I just answer my own question?

In any case, this threat to your dairy must be very stressful. Good luck!
