What do you mean by crossing time and space? There is no need to isolate the intersection with the trajectory of the confirmed patient 14 days.

The outbreak of the epidemic made everyone cautious. If the contact with confirmed cases often affects their daily life, work and travel, and some small partners' health codes indicate the intersection of time and space or accompany time and space, then what is the significance of the intersection of time and space? It means that the intersection of time and space intersects with the trip of the patient diagnosed within 14 days, and the intersection of time and space is located by the mobile phone number of the resident, which will lead to errors.

What do you mean by crossing time and space?

1, time-space intersection is the same concept as another saying, which means that in 14 days, it is in the same time-space grid as the confirmed patient, usually taking 800 meters *800 meters as the detection range, and * * * stays for 10 minutes. In layman's terms, it is crossed with the travel trajectory of the confirmed patient 14 days. No matter whether the communication signal drifts or passes by, it may be considered as a time-space intersection crowd.

2. The health code will turn yellow after being judged by the system as time-space crossing. For this kind of personnel, it is necessary to carry out nucleic acid detection twice every three days. After all nucleic acid test results are negative, the green code will be restored. If it is only the intersection of time and space, there is generally no need for isolation.

3. If you are assigned a yellow code due to misoperation, you can submit a complaint on the health code platform. If it meets the conditions of code change, the system will handle it within 24 hours; If the result of the first nucleic acid test is negative, the health code will turn into a green code for a short time, and then turn into a yellow code again, indicating that the space-time partner needs to carry out the second test as required. Only when the results of two nucleic acid tests are negative will the health code officially become a green code.
