توضیح
The disease entered Europe through Mediterranean ports and then moved outward along roads and shipping lanes over the next few years, reaching the far north and east by the early 1350s. The single-month version fails because travel then moved at the pace of ships and carts, so the spread of an infection carried with traffic was measured in seasons rather than weeks.
