That's my opinion, anyway.

The commonly accepted explanation is that the Black Death that killed 30% - 50% of the population of Europe was the bubonic plague, transmitted by fleas carried by rats. There are a number of difficulties with this.

The Black Death wiped out 50% of the population of Iceland. Well, how many rats were there in Iceland? Zero. None. No rats because it's too cold.

The Black Death moved far too quickly to be transmitted by fleas, at a rate of several miles per day.

The symptoms were different from bubonic plague and it killed much quicker.

So what was it and when is it coming back to inflict a massive death toll?
