Dragon Boat Festival is the earliest health and epidemic prevention festival in China. How did people prevent epidemic in ancient times?

According to the historical records of China, Dragon Boat Festival is a health and epidemic prevention festival in China. In ancient times, people's epidemic prevention was basically the same as that in modern times, but the tools and methods used were different:

People in ancient times reported the epidemic quickly after they found it. Modern people will directly report the epidemic situation to the relevant departments through mobile phones or the Internet, and the transmission speed has basically reached a real-time state. In ancient times, it may take 18 days to half a month from the discovery of the epidemic to the report, because people in a village need to report the epidemic to the local yamen, and the yamen has to ride to the capital overnight to report to the emperor. It may take 10 days to come and go, and the number of people who died in this 10 day is uncertain. Finally, it is necessary to carry out epidemic prevention and control according to the instructions issued by the emperor.

After the epidemic is discovered, it is also necessary to isolate and block the epidemic. After the epidemic was discovered in ancient times, local officials would open a place in the city to isolate people in this place. For several days, people need to bring their own dry food. It is not surprising if there were deaths during the quarantine period, because there was no effective treatment at that time, and only the greatest measures could be taken to ensure that the people were not affected by the epidemic.

After isolation, a large area of disinfection is needed. In ancient times, people used large equipment or some special disinfectants such as disinfectants and alcohol, so they could only bake with fire, kill viruses with high temperature or disinfect with some smoked things. Although it can't achieve 100% disinfection, it can also effectively avoid about 40% of the epidemic virus. Finally, after a long period of time, when the epidemic subsides, the local authorities will lift the epidemic prevention and control policy and the local people will return to normal life.

All in all, the means are similar, but the tools used are advanced.
