Scurvy Madness

This dangerous disease causes painful swellings upon the lips, tongue and gums. When these burst—usually whilst sneezing—foul tasting and infectious pus sprays out, sometimes up to five feet away. A high fever induces hallucinations and a terrible thirst in the victim, who must be doused in water and kept cool at all costs. People in the grip of the madness have gone on violent rampages, made shocking admissions and caused dangerous scandals. Folk cures include strapping sufferers to a stout board and forcing either grog with vinegar and limejuice or a live frog down their gullet. It lasts on average a week.
