Apparently it was the other way around. It was spread from the east to the west via human contact and regionally rooted and spread via rats in the short term

When I was in grad school, I wrote a paper theorizing that it was spread via the Mongolian version of the Pony Express as they traveled across Asia and along the Silk Routes. I also put more stock into coughing/sneezing as main infection pathways. Like this paper contains a lot of theories I had as a young 22 year old baby nerd.
