What made the Black Death so deadly & do you think it's similar to coronavirus

In five years, Black Death wiped out an estimated 30 to 50 percent of Europe's population. This medieval plague was caused by the bacterium Yersinia pestis, which still circulates among humans. Genetic clues as to what might have made it so deadly, however, had remained interred with the tens of millions of victims.

Is it similar to the virus?
The answer is : well it’s kinda similar but not exactly.

Hope it helps ps have a great day:)
