What is The Bubonic Plague

The bubonic plague started out as a simple rat fever. When the fleas that lived on the rats found there way to humans that simple rat fever spread and turned into one of the largest killers starting approximately in the 1330’s. The fleas carried the disease from rats to humans once one human was infected that human could chough and sneeze on others witch would helped the infection spread. Once you are infected the disease slowly destroys the lymphatic system. The lymphatic system is like the cleaner of the body it gets rid of infections so once infected without treatment, the bubonic plague kills about two thirds of infected humans with in 4 days. 25 million people died between 1331 and 1336. the bubonic plague originated in or near china in the early 1330s.
