Judgment criteria for intersection of space and time

The intersection of time and space means that within 14 days, the patient and the confirmed patient or asymptomatic infected person stayed in the same time and space grid (usually 800 meters × 800 meters as the detection range). More than 10 minutes.

In other words, a confirmed patient or an asymptomatic infected person has visited a certain place within 14 days, and at the same time, his or her trajectory within the 14 days has intersected with a confirmed case or an asymptomatic infected person, whether it is physical contact. However, the drift in communication signals may be recognized as time and space accompaniment.

For those who are judged to be people at the intersection of time and space, there is no need to quarantine for the time being, but people at the intersection of time and space need to proactively contact your community, unit or hotel where you are staying with your personal situation. Please promptly inform this text message of the situation, implement nucleic acid testing and other epidemic prevention and control measures as required, and take personal protection.
