There were notable differences between the Picardy sweat and the English sweating sickness. Along with the rash observed in the Picardy sweat, the Picardy sweat appears to have had a different epidemiology than the English sweat. The English sweating sickness appeared to most heavily affect urban and highly populated areas, while the Picardy sweat was most prevalent in rural areas. It was noticed that individuals who slept close to the ground and/or lived on farms and fields more quickly contracted the disease. This supports the possibility that the disease could be rodent borne, common in hantaviruses.
