These diseases are spread from animal to human (Newquist 239, Adamloakun M.D. 718). The bacterium lives in rodents such as rats and is carried by fleas (Newquist 238). When the fleas bite humans, the bacterium spreads. There are three types of the plague, which include the bubonic, pneumonic, and septicemic plagues (Newquist 238-239).

What is the Black Death? The Black Death was a bubonic plague pandemic that struck England in the Fourteenth Century. The bubonic plague is a disease that occurs mainly in fleas and other small rodents, like rats. The Black Death was caused by fleas carried by rats, rats in which were very common in towns and cities (“The Black Death of 1348 to 1350”). The fleas would then bite into their victims, releasing the disease inside them.

This grave disease that marked the end of the middle ages and the start of the modern age is known as the Black Plague. Many wondered what the true cause of the Black Plague was and how it spread all across the world in such a short amount of time. Throughout its time period, many medical authorities and scientists sought to give rational explanations for the reasons why the plague was spreading and believed it was caused by several factors such as: “corrupted air and water, hot and humid southerly winds, proximity of swamps, lack of purifying sunshine, excrement and other filth, putrid decomposition of dead bodies, excessive indulgence in foods (particularly fruits), God's wrath, punishment for sins, and the conjunction of stars and planets” (Encyclopedia of Plague and Pestilence). The confusion and lack of scientific knowledge on the harmful disease caused much panic and triggered many outbreaks among individuals. Many people began to start placing cities and ships under quarantine, burning sulfur to purify bad air, burning clothes, and even blaming and killing Jews in hope that they could solve a cure or at least stop the spread.
Bubonic plague causes very painful, swollen lymph nodes, called buboes. These swollen lymph nodes are often first found in the groin area, which is "boubon" in Latin. This disease became associated with the term "plague" because of its widespread fatality throughout history. Bubonic plague was also known as the "Black Death" in Medieval times. This is because the dried blood under the skin turns black.
