The earliest recorded smallpox outbreak occurred in ancient Egypt. The mummy of Egyptian Pharaoh Ramses V who died in BC 1 156 showed signs of smallpox rash. The last recorded smallpox infection was a hospital worker in 1977. 1980 in may, the world health organization announced that smallpox had been successfully eradicated. In this way, smallpox became the earliest human infectious disease that was completely eliminated, and at the same time, human beings knew the least about smallpox.
From its initial appearance to its complete extinction, smallpox has a history of more than 3,000 years, and there are too many stories. The relationship between the emperor shunzhi and Emperor Kangxi in Qing Dynasty and smallpox has aroused more interest because there is no clear historical record. The emperor shunzhi was young and promising, but he spread to Kangxi, only 8 years old. There are different opinions about the reasons. It is said that the emperor shunzhi saw through the world of mortals, became a monk in Wutai Mountain, and later became a monk. It is said that smallpox caused the emperor shunzhi to die young. As for why the young Kangxi stood out and sat on the throne at that time, it was closely related to smallpox. Shortly after Manchu entered the customs in the early Qing Dynasty, the climate changed and communication with the Han nationality increased, so many people got smallpox, and the royal family was not spared. With the lesson of Shunzhi's early death, Kangxi, who had been infected with smallpox, had an advantage in the battle for the throne.
Whether these historical stories are true or not, it is conceivable that smallpox has brought great disasters to mankind. Therefore, it is necessary to understand smallpox virus today, when smallpox has disappeared. The smallpox virus that has been sleeping in the laboratory for more than 20 years will be revived again. Although they are only used for research, they have attracted the attention of some scientists.
