I wonder...
East Asia wasn't struck by the plague as far as I know. It was contained to Europe, North Africa and West Asia.
EDIT: Sorry. To clarify what I mean is that maybe the had means to quarantine people and stop the spread of infections diseases. Maybe their hygiene was much better too. A lot of it was due to poor Hygiene. But yeah, maybe a pandemic could have happened like anywhere else I suppose, sooner or later.
