You're correct. Both the bubonic and black plagues were bacterial not viral.I think, the Black Plague, was bacterial since it was caused by fleas. Can not judge what the worst virus is/was because this virus is not over yet. But, not counting this virus, SPanisn flu gets my vote.
Polio Not been a case of polio in US since1979. Eradicated by vaccine. | |||||
Hanta, not sure of spelling either, is spread by deer mouse droppings, if we are thinking about the same disease and I would lean towards it being bacterial. You catch it in Utah when you sweep the droppings up and the spores enter the air. You must “wet” the droppings before cleaning them up.Smallpox in terms of the volume of people impacted through the years. You won't let me google, so am not sure of the spelling but I think Hanta/Haunta virus in the US Southwest had nearly a 100% death rate. Fortunately not a lot of people contracted it since it was spread through rat droppings.

I have no ideal if rats spread this disease.
Is AIDS a virus? If it isn't, then I will guess the Black Death.
Spanish flu?
Using this definition I would say Covid because the consequences of the lock down mentality will be with us for years.Involving possible injury, pain, harm, or loss.
Likely to cause problems or to have adverse consequences.
I cheated, and "googled" the answer. According to various sources on the Internet, the "most dangerous virus of all time" is called Marburg Virus. I never heard of it, and it seems to be an issue only in parts of Africa....but the survival rate is Very Low.
https://ultimatetopics.com/most-dan...like Ebola, another extremely dangerous virus.
Tsk, tsk....
That seems to be the answer to the OP's specific question, but in overall terms of the numbers of people infected/killed, it ranks way down the list.
Of all time is your time frame. Most dangerous ever.We need a time frame, don't we? 1400's...
If people are dropping like flies-no one knows why, that has to be terrifying.
There were no physicians, no knowledge on how to cope-do you escape by running, shelter in place ()
We in the West, know the Black Death ravaged nations in the East, but we do not know how severe it was.
We had some information about the Spanish Flu, but not how to stop it's spread, or how to 'Fix those infected.'
(Shelter in place, avoid others is fake news, put forth my hermits seeking acceptance
