How did the plague in ancient history end and who survived?

Nowadays, science and technology are developed. When the plague breaks out, a vaccine can be developed in a short time to stop the spread of the plague. But in ancient times, when a large-scale plague broke out, people basically had to rely on their own immunity to fight the virus.

This means that only some lucky people can recover after getting sick in the plague and get antibodies to survive, while others who can't survive can only wait for death. Therefore, the great plague in history ended not because human beings had some medical means, but when the virus infected most people, those who passed the screening gained group immunity.

During the period from 1347 to 1353, the Black Death prevailed in Europe, causing 25 million deaths, accounting for one third of the European population at that time. However, mankind has never been able to cure the Black Death. The Black Death almost destroyed European civilization, and its threat even surpassed that of World War II.

So far, there is no accurate conclusion about how the Black Death ended. The scientific point of view is that the sanitary environment in Europe has been gradually improved, which has curbed the spread of the Black Death to some extent. On the other hand, a large number of people died. European countries began to forcibly isolate foreigners and patients and burn the bodies of the deceased, which slowed down the spread of the virus. The high death rate of the Black Death and the short time from illness to death have also become the reasons why the virus has not spread further.

In contrast, China has been more scientific in preventing and controlling the epidemic since ancient times than Europe. During the Shunzhi period, smallpox virus spread in Beijing, not only in the homes of ordinary people, but also in many royal families. At that time, they either suffered from smallpox because of their own immunity or died of smallpox, which was equivalent to a terminal illness.

Before the emperor shunzhi took office, Dourgen ordered the patients to be isolated, and all people who entered and left Beijing should be examined and buried. Although this can effectively prevent the spread of smallpox virus, it can't stop people from coming and going because of the lack of means to treat smallpox virus, so smallpox is still spreading and spreading in Beijing.

There were also many people infected with smallpox in the imperial court, including Dong E Fei, who was very fond of Emperor Shunzhi. Later, Emperor Shunzhi was infected and his health became worse and worse. In order to stabilize the rule of the Qing Dynasty, he urgently needed to choose a successor. Emperor Shunzhi had six children, two of whom died young.

The emperor shunzhi's third son, Michelle Ye, miraculously recovered from smallpox. After listening to the advice of Minister Tang Ruowang, the emperor shunzhi decided to abdicate to Michelle Ye, mainly because he was immune to smallpox virus, but the plague did not end because Emperor Kangxi succeeded to the throne.

In the 19th year of Kangxi, Prince Yin Ren was also infected with smallpox. Emperor Kangxi sent Fu Ge Wei to Beijing to treat Yin Ren. Fu Gewei was good at vaccinating children. Vaccination against smallpox became popular, and smallpox was gradually effectively curbed.

In fact, in the Song Dynasty, there was a method to prevent smallpox by inoculation with "human pox", but because the virus could not be inactivated and the risk was very high, this method has not been popularized. With the progress of science and technology, these once frightening viruses have disappeared today.
