I meant that (99%) are the humans to transmit ME animals .... although of course the reverse is possible, and how human animals transmit it to other animals ......
You still state the 99% number without giving any evidence whatsoever. Dogs for example don't catch most of the human viruses at all, they catch special form of canine viruses (source), so there is no reason to think 99% of dogs get "infected" with the hypothetical ME virus from human.
