Black death is an explanatory term used to describe the initial occurrence and expansion of the plague between 1347 and 1352 in Europe, Levant and North Africa. During the fourth century after the first epidemic, Europe repeatedly experienced the epidemic of plague. Due to the wide-ranging social and economic influences of the epidemic, black death has become the most serious disaster in human history. However, the lack of sophisticated medical technology and accurate diagnosis during this period is causing controversy about epidemics.
In 2002, Samuel K. Cohn published a controversial article "Black Death: The End of the Paradigm". Cohen noted in this article that Medieval and modern plague are two different symptoms, signs and epidemiology. Cohen argued that the pathogen Yersinia that causes Pestopst occurred first in Hong Kong in 1894. Next, according to Cohen, the medieval plague that struck Europe was not a traditional plague of mice. Scientists and historians agree
Black death is thought to be a combination of three different types of plague, peritonitis, pneumonia, septicemia. The most common one is peritonitis. The first symptom is a headache followed by nausea, vomiting, joint pain, poor physical condition, and black swelling. May die two or three days after the first symptoms. Researchers also discovered that rodents spread through all insect bites that normally aid rodents. It is well known for swelling of armpits and neck.
Glandular plague, commonly known as black death, is carried by rats and is a disease transmitted by fleas. Before an obvious symptom appears, the infected person suffers great swelling, dies quickly, or dies after a symptom of sneezing with suddenly roughened face like a sudden fever. Then raise your blood. However, in the late 1340s, the outbreak of Black Death occurred in Europe. Over the next few years the disease killed most of the European population. Although the plague has disappeared, it has brought about a great cultural change in Europe. There is a big impact on culture, spirituality and especially economics.
