Sweating Sickness -- Thanks Reeves

From Wikipedia, the free encyclopedia

Sweating sickness, also known as the "English sweate" (Lat. sudor anglicus), was a mysterious and highly virulent disease which struck England and later Europe in a series of epidemics the first beginning in 1485 and the last in 1551, afterwards apparently vanishing. The onset of symptoms was dramatic and sudden, with death often occurring within hours. Its cause remains unknown.
