How did ancient people deal with infectious diseases?

The medical technology of the ancients was not as developed as it is now, but their understanding of infectious diseases was very profound.

When an infectious disease is found in a certain place, it will be reported to the court as soon as possible, and the power of the whole country will be collected for treatment; When the imperial court learned about it, it would immediately send medical officers to treat it, use the state treasury to collect medicinal materials and send them to the epidemic area; After that, the patient was treated in isolation to prevent further infection; Then the government will pay to bury the body to prevent the virus from spreading; The last thing they can do is to improve the water source.

The ancients can only do this in the face of large-scale disasters. After all, the medical level is limited. What else? Do what you have to do. .
