It is seen most frequently in individuals between fifteen and thirty-five years of age. Among the causes of the affection are mentioned pregnancy, lactation, exposure to cold and wet, intestinal irritation, and mental shock. It sometimes occurs as a sequel to scarlet fever and other diseases of childhood. The disease seldom results fatally, except when the muscles of respiration are profoundly affected.
