It was around 1339 AD when the pandemic broke out. The scythe of death swept across Europe, losing only a few serfs and nobles. The foundations of middle-aged life collapsed, it was the moment Europe changed. This would be well known as the Black Death or the Bubonic Plague. We now know that the Black Death is transmitted by a flea. However, this flea was not the cause as it was the bacteria lying in the flea's stomach. The scientific name of this bacterium is Yersinia pestis. The flea's main host is a rat, scientifically called Rattus rattus. Humans contracted the disease because, when rats reproduced rapidly, this would lead to an invasion of the population. When the mouse dies, the flea should find another warm-blooded host to feed on, and next to them are humans. The flea bites the man and infects him. The unhygienic living conditions of the Middle Ages led to a faster spread of disease, consequently creating a better environment for rats to live. Lack of knowledge in the 14th century led to even worse remedies. During the Middle Ages, people did not have scientific equipment such as microscopes to examine organisms. Then they concluded that the causes of the Black Death were based on unsupported evidence. Many doctors and doctors said it was in the air. It was inevitable that they would capture the Death Star as they claimed. Doctors describe the plague as a “tide of death” (Addison et al, 2012. Page 299). However, the Church said it was the wrath of God. The priests explained that people had sinned, including sins of greed, sins of pride, sins of theft, sins of envy, sins of lying, and sins of anger. An unusual cause was that people thought the movement of the stars would reveal when the plague would strike, while some places even disprove... middle of paper... the world was changed economically, religiously and demographically. Will Death finish the job next time?
