Fleas responsible for spread of Black Death

Researchers have confirmed that the plague that wiped out 60% of the population of Europe was transmitted by fleas.

Their findings, published in an online journal, provide final proof that the plague spread via the transmission of the bacteria Yersinia pestis, which was passed on through bites from fleas carried by black rats.

This effectively rules out other common theories, including that the Black Death was actually a fever, and resolves a long-standing debate about the cause of the devastating disease.
