There were two types of the Picardy sweat, a benign form that was similar to nephropathia epidemica and a more severe form that resembled the English sweat. The disease was similar to the English sweat but differed in some symptoms and in its course and mortality rate. Additionally, the more severe type of Picardy sweat is believed to be more benign than the English sweating sickness. The rate of sickness was anywhere from 25% to 30% of the population and the mortality rate is estimated to have been between 0% and 20%. Similar to the English sweat, the more severe Picardy sweat was characterized by intense sweating, but the symptoms were less fatal. Some of the symptoms were high fever, rash, and bleeding from the nose. Other symptoms include intense sweating, headaches, suffocation, precordial pain, anxiety, and "passion of the heart" or palpitations. Additionally a miliary rash followed by desquamation, or peeling of the skin, is a fresh feature that was brought on with this variant of the English sweating sickness would typically appear three to four days after infection. Many victims died within two days.
