During the epidemic, I don’t know what it means to put something beside the door to tell you not to go out.

During the epidemic, I didn’t know to put something beside the door to tell people not to go out. The purpose is to put a sign to remind everyone not to go out

The purpose is to prevent the spread of the epidemic and be responsible for yourself and your family. , responsible for the whole society!

The reason why they are not allowed to go out:

Suppose there are three types of people A, B and C. A has a history of contact with Hubei. There are currently 5 million people scattered across the country. It is easy to find them. Many have been found now.

A meets B whom he has never known before during his journey.

After A arrives at the destination, it comes into contact with C. No matter how many Cs it comes into contact with, these Cs can be found and have been isolated.

The biggest hidden danger now is that B can’t be found at all. No one knows who B is, and B doesn’t know that he is B at all.

The purpose of everyone's isolation now is to use time to screen out B. The incubation period is two weeks. Within two weeks, B will become ill one after another and the truth will come to light. The epidemic will not end until all B's are sick.

So all the measures taken by the country now are to reduce the generation of new B. The current epidemic situation is very serious. The general public must be alert and fully aware of the concealment, rapidity and severity of the spread of the virus. Only by staying at home can you and your family be protected.
