Between 1718 and 1918 an illness with some similarities occurred in France, known as the [[Picardy sweat]].<ref>{{cite book|last=Foster|first=Michael G.|title=Contributions to Medical & Biological Research|chapter=Sweating Sickness in Modern Times|pages=52–53|volume=1|publisher=Paul B.

It was accompanied by a rash, which was not described as a feature of the English disease. Henry Tidy argued that John Caius's report applies to [[fulminant]] cases fatal within a few hours, in which case no eruption may develop. The Picardy sweat appears to have had a different epidemiology than the English sweat in that individuals who slept close to the ground and/or lived on farms appeared more susceptible, supporting the theory that the disease could be rodent-borne, common in hantaviruses.<ref name="Heyman 2014b"/> In a 1906 outbreak of Picardy sweat which struck 6,000 people, a commission led by bacteriologist [[André Chantemesse]] attributed infection to the fleas of field mice.{{cn|date=March 2025}}
