“It was known in Cromwell’s time as sudor anglicus, meaning the ‘English sweat,’ and there were five outbreaks of it in England, the first in 1485 and the last in 1551. Victims did, in fact, often die within hours of their first symptoms, developing a high fever and ‘copious malodorous sweating.’ … Because the disease killed so swiftly, and because it had other peculiar features — it seemed mainly to affect English people, even when it travelled across borders, and it was particularly infectious among wealthy young men — superstitions abounded.” – The New Yorker
