i just started reading a book called Between Two Fires set during the black death (1348). it's fiction, "medieval horror," it's awesome so far highly recommend. But that's how I ended up here. I already love prof. dave and I was on the wikipedia page for the black plague, and i ran across Yersinia Pestis and wondered what youtube results there'd be for specifically "yersinia pestis." was quite happy that professor dave was the first result, awesome video. I like that it is both casual but also informative like a lecture. great combo.

Untreated pneumonic plague is not 90% but almost 100%. In the Manchurian outbreak (1911) out of 60 000 patients that were infected, it is said only 2 survived the disease.

not necessarily just 3 outbreaks. It is very possible that there was a similar plague that hit the Bronze Age at the beginning of the13th Centure BC ie 1300 to 1280, it devastated the Hittite Empire and perhaps set the stage for the downfall of all Eastern Mediterranean Bronze Age empires over the next 100 years

The first case of bubonic plague in Australia was reported in January 1900. But it is extremely rare in Australia, that's right. Wild rodent plague mostly exists in rural parts of the Americas, the former Soviet Union, Africa and Asia.

Decimating comes from the latin word for 10th and it means to destroy or kill one tenth of something, so the plague actually did technically decimate us
@ProfessorDaveExplains 3 жыл бұрын
I think it means to reduce to only one tenth, no? So actually it almost literally did.

Nerd pet peeve. The improper use of the word decimation. The word originally referenced the Roman legions form of punishment of killing every tenth man. So in actual terms the plague didn't "almost" decimate humanity. At least a couple of times it more than decimated humanity. Beyond that, really enjoyed your show.

@kingseiryu929 2 жыл бұрын
It's always a trade off between deadliness and contagious. If it kills ppl off too fast, no host will remain well enough or alive to spread it. Covid is contagious but not super deadly. A hybrid between both will probably look more like current covid
