Sadly, when it appeared in the 1300’s no one knew what caused it, how to treat it or how to stop it. In 2011, scientists were able to confirm that it can be traced to the deadly microbe Yersiniapestis, and that it did indeed originate in China (Cole and Symes, 2010, p. 353).

However, as scientists later discovered the bacteria is one that gets stuck in a flea’s digestive tract. As it enlarges fleas begin to starve and to try and fight their own death from starvation they jump from rat to rat biting them, trying to survive. The blockage prohibits the rat from becoming able to swallow the blood. The fleas in turn vomit the blood along with the bacteria, which ends up in the rat’s blood stream.
