Galvani speculates the plague rats have been in Dunwall for the last 5 to 7 years.

Perhaps the first outbreaks of the plague happened not long after the rats had been introduced and established themselves, either way it seems the plague was ravaging Dunwall a good couple of years before the main part of the game. I suspect Corvo's trip round the Isles took a few months to complete and the plague was supposedly bad by the time he left.
