Again, in human evolution you are NOT going to always have records of overlap when a legend gets passed on. Geography most certainly comes into play and when you know how close Egypt is to Mesopotamia and that that entire region has had its power shifts and overlap Ocham's razor points to the simplest solution as to how stories end up where they do. The get passed down through humans and time and can have the same motifs but completely different character names and details by the time they get written down by someone and you don't always have a record of that overlap.
The plague story is a result of conflating a natural event to comic book status, just like all flood myths. It is a legend born out of human ignorance. Just like all comet myths and flood myths in human history get created. The story was put in the bible to give the writers legitimacy, but we can only conclude it was put there AFTER the fact regardless of how got there or who passed it on to them.
