No, the first plauge won't spread to France
It's already limited to Byzantium, and the Italian minors (then part of Justinian's realm)
I just wanted to try to actually finish a game with France, when this happened:

seriously? -.-
Milan is not ing part of Justinians realm! It is mine

(next turn it spread to Firenze...and 2 barbs appeared just next to the 2 now undefended cities -> I quit)
edit:
tried again, was again hit by the plague in those 2 cities and the barbarians appeared during this time.
I ended up worldbuildering the mounted one that just came out of nowhere (only 1 archer survived and had to be used as defence for both cities) but was still left with both cities empty, size 1, no building in 650.
this just sucks.
I mean not conquering isn't even an alternative as a) you need these two (or at least milan) to build enough troops and b) the barbs would just raze them anyway -.-
edit2:
okay I played untill 710 this time. Milan and Firenze were about size 3, but my stability suffered gravely throughout, I had no production at all (but research was coming along nicely due to the low number of cities) and then they declared their independence right after they finished their first post-plague-defender. yeay -.-
The plague essentially destroys all possibility to defend these 2 cities and the barbs are free to pillage the improvements around them, driving my stability in the ground. (from +2 to -8)
