How did the Black Death sweep through medieval Europe? How did it end?

At that time, the Black Death, as a latent virus, was carried by some people at that time and finally spread. Later, because someone had strong resistance and would not spread again, the Black Death gradually disappeared. Speaking of the Black Death, it was probably a big virus in Europe in the 1940s and 1950s, because the Black Death probably ended the lives of 25 million Europeans, which was equivalent to 1/3 in Europe at that time. Now everyone should know that the Black Death, also called plague, is very easy to treat under the current medical conditions.

The so-called Black Death was caused by a mouse carrying a virus, and according to some data, the pathogen carriers of these sunspots were the Qincha Khan fighters at that time. At that time, when Chincha Khan attacked Kafa, a city in the corner of the Black Sea, the Mongols suffered great losses, not only economic losses, but also heavy casualties. At that time, they already knew that some viruses were carried among their dead, so they threw the bodies of these dead soldiers in Kafa. It was because of this move that people in this city soon contracted the Black Death. Then the city was invaded by Mongolia, but what everyone didn't expect was that the Black Death didn't end with the end of the war.

At that time, many Italians lived in Kafa. After Kafa was captured, these Italians fled back to their hometown, but what these people didn't know was that sunspot disease also existed in them, and they took it to their own country as a carrier. So sunspot disease broke out further. Moreover, the major cities in Europe at that time were not so good and the environment was even worse. They like this harsh environment, so when the carriers brought the virus to these cities, the virus spread more unscrupulously, and the Black Death increased the intensity of infection out of control. What makes people feel terrible is that even people in the countryside have not avoided it.

The Black Death swept through Europe in six years, but it ended later because people were properly isolated, and some people were immune to the Black Death, so the Black Death died by itself as time went on.
