Adults receive epidemic prevention information with overlapping time and space. Can children still go to school?

The epidemic prevention information received by adults crosses time and space, so children can't go to school.

I was told that there was an empty intersection at the same time as the confirmed cases in COVID-19. At this time, the children at home can't go to school. The whole family should immediately contact the community, unit or hotel where they are staying, inform the news in time, and implement epidemic prevention and control measures such as nucleic acid testing as required, and try not to go out. If you really need to go out, please wear a mask, do not take public transport, and do a good job of self-health monitoring, such as fever, dry cough, stuffy nose, runny nose and so on. Please wear a mask on the way to see a doctor, do personal protection, and don't take public transportation.

The concept of "space-time intersection" is the same as that of "accompanying space-time", which refers to the person who stays with the diagnosed patient for 14 days and * * * stays 10 minutes in the same space-time grid (usually 800 m× 800 m as the detection range). The purpose of screening "time-space companions" is to find the potentially dangerous population to the greatest extent, and to include more people who may be infected with "time-space overlap" in key investigations, so as to truly realize early detection and early prevention and control.
