I know nothing but the main threat from this is that it appears to be airborne.
It must be really airborne here on the San Francisco peninsula because everybody acts as if there’s a huge, poisonous gaseous COVID cloud everywhere in the outdoors.
I passed a teen lass yesterday on a trail and she saw I wasn’t wearing a mask, so she put up a binder she was carrying on the side of her face! It made me crack up...as if that action would have ANY effect on transmission.
