OK so the English sweat is basically a short, very fast onset sickness. You’re dead or going to live in a day. Very sudden onset of sweating, high fever, cardiac palpitations, and people literally just dropped dead. Or started pissing gallons and got better.
Some interesting things about it.
-there were five main epidemics
-the disease hit the English really hard. There were very minor outbreaks on the continent but nothing too bad. This was a disease associated with the English
-Sweden and Denmark and Russia got hit too.
-The disease appeared irregularly, in summer and apparently after hard rains (suggests that the weather was a factor somehow, perhaps in crop fungus or mouse or VOLE explosion.)
- outbreaks moved west to east. This is important because flu and almost all other pestilences moved east to west, it suggests an origin in the west, rather than the typical flu or other horror which originates around the levant, crimea or china and moves westwards.
- There was a thing called the Picardy sweat but it wasn’t quite the same
- It predominantly killed healthy and RICH young men, 20-45 sort of age. -The monasteries were badly hit hit
- It didn’t seem to hit very young children or the very elderly.
- No rashes or buboes are recorded. The Picardy sweat did have rash
- Never really happened in Scotland or wales. Contemporary writers mused that the tall fair haired races were susceptible
- Getting it and recovering provided no immunity at all. (Argues against a virus.)
Arguments for a hantavirus.
Well it could have been one, but they don’t kill that fast, not the ones we know. Hantavirus is more like feeling like you’ve got a bad flu, then pneumonia then dead.
- seasonality. Could be associated with a mouse vector.
- Polyuria on recovery
- -difficulty breathing
- -occurrence after flooding suggests a vector that wasn’t usually around humans but was displaced.
Against hantavirus. Too fast, The poor would surely have been affected more, being in the fields, and children, playing in the floor in the dust and inhaling dust from rodent poop would have been too.
Other possible causes.
- Anthrax. This is possible, but anthrax gives skin lesions and these weren’t widely reported (some apparently had black spots but not all.)
- A mosquito bourne arbovirus. Possible as well, especially after reports of flooding or hard rain before . Doesn’t explain why children and the elderly didn’t get sick
- Ergotism - fits with the rains, sudden onset, and recovery and no immunity, but not other features
- Something tick bourne
- Something food related - might fit with the demographics, if it was a food consumed mainly by higher status people.
No explanation is very satisfactory. If it was a virus endemic to the uk, why was it only seen in such restricted outbreaks and disappeared?
Mozart, by the way, is supposed to have died of the Picardy sweat or similar.
I’ll do encephalitis lethargica later, because I’ve just had some thoughts about covid and I want to think them for a while
