There have been many literary plagues in human history, all of which have come and gone without a trace, which has made many scholars ashamed. After all, in ancient times, human beings lacked a direct and effective way to deal with epidemics, and could only use conventional means such as isolation, which was not enough to eradicate epidemics. But strangely enough, all epidemics will always disappear one day, although no one knows where it went. The Black Death, which has been circulating in Europe for hundreds of years, is one of them.
The hostility of Europeans to cats caused rats to begin to flood, and rats appeared in everything. The Black Death was one of the most important symbols of the Middle Ages, which evaporated more than half of Europe's population from the earth and lasted for more than 500 years, arguably the longest epidemic of humanity to date.
But once the cats are reduced, will there be a Black Death? There is no necessary connection. In addition, the Spanish flu that occurred before and after the First World War also did not know what to do, and it ended up. The pandemic has also spread almost universally, but it is mainly concentrated in Europe, and the number of deaths in Places such as Asia is very small.
After world war I, the Spanish flu also disappeared quickly, as if it never existed. Today, humans can still find the plague bacillus of the Black Death in ancient tombs in many parts of Europe. It is not easy to trace the source of the epidemic hundreds of years ago.
Because Y. pestis has been mutating for so many years, scientists have found the oldest source, which may be from a small town in the Volga River, and only this town has the earliest origin of Y. pestis. But that still doesn't serve as the final answer to the question. The disappearance of the Black Death was indeed a blessing for mankind, and it was hoped that it would not come again in the future.
