True. I’m not sure what your asking, but that is a true statement.
I know for sure one group would be merchants. They were the ones travelling to potentially infected areas---buying things with the plague's germs, and selling it to people on areas that WEREN'T previously infected. Sailors too I believe, for very similar reasons and because rats were infected, and rats caught rides on ships and spread the disease wherever the ship docked.
Hope this helped. :)
