The Black Death (Black Plague or Bubonic Plague) was believed to be caused by the Yersinia Pestis bacteria living in fleas and was passed primarily through flea bites. In very rare circumstances like the septicemic plague the disease can be transmitted by direct contact with infected tissue or exposure to a cough of another human. The fleas are often found on rodents such as rats and mice, and seek out other prey when their rodent hosts die. The bacteria remained harmless to the flea, allowing the new host to spread the bacteria. The bacteria form aggregates in the gut of infected fleas and this results in the flea regurgitating ingested blood, which is now infected, into the bite site of a rodent or human host. Once established, bacteria rapidly spread to the lymph nodes and multiply.
The plaguespread around the world on black rats which would get onto merchant ships. It is believed that the black death originated in Asia.By the way, 'Spread' isn't spelt 'spred', it's - spread
The Plague spread from Asia to Europe where it was more deadly because the Europeans hadnt yet built up an immunity to it. It was carried from Asian fleas on Asian Rats that were then transported on Itlaian Transport ships to Europe
The Black Death was a disease of rats and other rodents. When diseased rats were bitten by fleas, the fleas also contracted the plague. When the rats died, the fleas on them looked for warm blooded animals to bite, and humans were often the target. As infected fleas bit people, they often vomited on the place they were biting, and the germs got into the people, infecting them.
