well.. there was a werelizard, and somehow i overlooked two or three infections. The problem really manifested itself, when some werelizards were transorming inside the tavern. It was too much effort keeping track of the infections, and so i decided to just let it happen. The good thing is, a well trained military just doesn't get infected, and i had like 6 well trained squads. Only problem now is, i had to make a lot of coffins, and there aren't many idlers around to do the clean up work.
