From what we saw in the Canadian teen: It’s only a mutation away from ripping through humans in a real bad way. It picked up the mutation it needed to switch from preferring the alpha 2,3 receptor plentiful in birds to the alpha 2,6 sialic acids that are plentiful in the human nose, throat and lungs when the teen was infected. That teen then developed ARDS and she needed to be intubated.
