What do you mean by crossing time and space? Who is the intersection of time and space?

The intersection of time and space is actually the companionship of time and space.

1. Time-space intersection "is the same as" time-space companionship ",which refers to the person who stays with the diagnosed patient for 14 days in the same time-space grid (usually 800 m× 800 m as the detection range).

2. In layman's terms, for example, an infected person has been to a certain place within 14 days, and the trajectory of your 14 days intersects with him. Whether it is a physical brush or a drift in communication signals, it may be considered as a space-time companion.

There is no need for isolation for the time being.

1. "Time-space intersection" is a professional term used by public security and telecommunications departments. Space-time intersection and space-time accompaniment are the same concept, which means staying in the same space-time grid (800 m× 800 m) with the diagnosed patient within 14 days 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.

How many days does it take for the yellow code to turn green at the intersection of time and space?

If it does overlap with the confirmed cases in time and space, it is suggested to report to the local community at the first time, and conduct two nucleic acid tests within 3 days, with the interval between the two nucleic acid tests being more than 24 hours. If all the nucleic acid test results are negative, you can remove the time-space association and restore the green code at the same time, but please stay at home until the nucleic acid negative results come out.

If you are assigned a yellow code because of 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.

Should the yellow code be isolated at home?

Persons whose health code is yellow shall, in principle, be monitored at home for 7 days and go to the nearest nucleic acid testing point for testing as soon as possible. When the health monitoring expires and the nucleic acid test result is negative, the system will automatically change the yellow code into the green code after receiving the relevant test data, and remove the health management measures. If there are special control requirements, corresponding control measures should be implemented according to relevant regulations. If the health code is distributed by other provinces, it shall be solved by the original channel.
