the fleas where the start whom travelled from china, they had a bacteria in them which the fleas where immune to this bacteria was called versinnia. when the fleas bit the rats (black rat's ) drink the blood they would vomit out that bacteria that the rat wasn't immune to... soon the rat would die. after the fleas wiped out all the black rats they had no food so they moved onto the the humans and animals! so technically it wasn't the fleas who caused the plague it was the bacteria versinnia
Rats bit humans.

Rats to fleas, fleas to humans
Fleas transmitted the disease from rats to humans.
The black death (the plague) could be passed on by either an infected person or fleas on animals such as rats. Due to the awful insanity in those days, rats were incredibly common.
Actually, fleas did. They spread on rats which attacked humans.
rats got infected by Yersinia pestis bacterium. When they die fleas spread bacteria to humans.

The Black Death was spread by fleas which lived on black rats.
the black death was carried by fleas that were on rats and the rats were on boats and they were carried over
