What does the intersection of time and space mean?

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

1. The concept of space-time intersection is the same as that of space-time accompaniment, which refers to the person who stayed with the diagnosed patient for 1 minutes in the same time and space grid within 14 days (usually taking 8 m× 8 m as the detection range).

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

isolation is not needed for the time being.

1. "Intersection of time and space" is a professional term used by public security and telecommunication departments. Space-time intersection and space-time accompaniment are the same concept, which means that within 14 days, they stayed with the diagnosed patient for 1 minutes in the same time and space grid (8 m× 8 m). In layman's terms, it has crossed with the travel trajectory of the confirmed patient within 14 days. Whether the communication signal drifts or passes by, it may be identified as a time-space intersection crowd.

2. After being judged by the system as the intersection of time and space, the health code will turn yellow. However, for this kind of personnel, it is necessary to carry out nucleic acid detection twice every three days, and after all the nucleic acid detection results are negative, the green code will be restored. If it is only the intersection of time and space, it is generally not necessary to isolate.

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

If there is a real intersection of time and space with a confirmed case, it is recommended to report it to the local community at the first time, and at the same time, conduct two nucleic acid tests within three days, with the interval between the two nucleic acid tests being more than 24 hours. If the results of nucleic acid tests are all negative, you can remove the space-time accompaniment and restore the green code at the same time, but please stay at home until the negative results of nucleic acid come out.

If you are given a yellow code due to wrong operation, you can submit a complaint on the health code platform. If you meet the conditions for changing the code, 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, which indicates that the space-time companion needs to carry out the second test as required. Only when the results of the two nucleic acid tests are negative, the health code will officially turn into a green code.

Should the yellow code be isolated at home?

In principle, people with yellow health code should be monitored at home for 7 days, and they should be tested at the nearest nucleic acid testing point as soon as possible. When the health monitoring expires and the nucleic acid testing result is negative, the system will automatically turn the yellow code into a green code after receiving the relevant testing data, and the health management measures will be lifted. If there are special control requirements, the corresponding control measures will be implemented according to relevant regulations. If the health code is assigned by other provinces, it will be solved by the original channel.
