Answer: The disease spread by fleas being carried around on rats. In the filth and the warmth of the summer heat, the rotting rubbish is a perfect place for bacteria to breed. People living in the infected area had to sanities in order to try and prevent the disease from spreading. When people died from the plague, they hardly every let anyone see the deceased to try and stop the spread. Bubonic plague Is a zoonotic disease, circulating mainly among small rodents and their fleas, and is one of three types of bacterial infections caused by Yesinia pestis (formerly known as Pasteurella pestis), which belongs to the family Enterobacteriaceae. Without treatment, the bubonic plague kills about two thirds of infected humans within…show more content…
pestis—is generally believed to be the cause of the Black Death that swept through Europe in the 14th century and killed an estimated 25 million people, or 30–60% of the European population. Because the plague killed so many of the working population, wages rose and some historians have seen this as a turning point in European economic development. The signs and symptoms of bubonic plague. The most infamous symptom of bubonic plague is an infection of the lymph glands (lymphadenitis), which become swollen and painful and are known as buboes. After being transmitted via the bite of an infected flea the Y. pestis bacteria become localized in inflamed lymph where they begin to colonize and reproduce. Buboes associated with the bubonic plague are commonly found in the armpits, upper femoral, and groin and neck region. Acral gangrene (i.e. of the fingers, toes, lips and nose), is another common symptom. Due to its bite-based form of infection, the bubonic plague is often the first step of a progressive series of illnesses. Bubonic plague symptoms appear suddenly, usually 2–5 days after exposure to the bacteria. Symptoms…show more content…
The Black Death was one of the most devastating pandemics in human history, peaking in Europe between 1348 and 1350. Although there were several competing theories as to the etiology of the Black Death, recent analysis of DNA from victims in northern and southern Europe indicates that the pathogen responsible was the Yersinia pestis bacterium, which causes the Bubonic plague, although these were different, previously unknown ancestral variants of those identified in the 20th century. The Black Death is thought to have started in China or central Asia, before spreading west. It is estimated to have killed 25 million people or 30% of the population of China. The plague then travelled along the Silk Road and reached the Crimea by 1346. From there, it was probably carried by Oriental rat fleas living on the black rats that were regular passengers on merchant ships. Spreading throughout the Mediterranean and Europe, the Black Death is estimated to have killed 30–60 percent of Europe's population. All in all, the plague reduced the world population from an estimated 450 million to between 350 and 375 million in the 14th
