What is Ebola?
So you don’t think those doctors sited know those basic facts?
Some cases of the Black Death did not fit the symptoms of bubonic plague.
I agree with you that the Black Death was caused by Bubonic Plague because newer research has found evidence for Plague in the mass graves.
However, lymph nodes can swell massively, and turn purple, in response to any kind of infection - not just bacterial.
Buboes, the swollen lymph gland, is where we get the child-like term "boo-boo", for any random injury a kid might suffer.
If you read the literature carefully, there is evidence that the "Black Death" consisted of more than one infectious agent. The most common and best understood is bubonic plague, of course, but this infection could also manifest in the lungs or the circulatory system with different symptoms. There's also some evidence that another, as-yet-unknown infectious disease was involved and ran rampant along with the plague bacteria.
Until it gets into the lungs. And I would wager that a lot died as a result back then.
So, make crazy connections until they beg Big Brother to save them.
How long until Ebola is compared to Scarlet Fever?
Read the old accounts.
The Buboes sometimes were bloody, and not all had them. There was also subdermial bleeding (look up pictures of Marburg victims), blood out of all the orifices, and many other symptoms not associated with Y. Pestis.
So while I (personally) think that much of it is explained by Y. Pestis, some of the symptoms suggest another disease.
Not saying it was Ebola. There are a number of hemorrhagic fevers.
