According to the system detection, the abnormal reason of yellow code is: time and space accompanying. "
What is "accompanying time and space"? What magic does it have?
Code turns yellow?
"Space-time companionship" means accompanying the diagnosed patient within 14 days.
In the space-time grid (usually 800 meters * 800 meters
Detection range), and stayed together for 10 minutes. Like diagnosis.
The patient has been to a certain community within 14 days, and your trajectory is correct.
Patients have had an intersection, whether it is a physical brush or
No matter the drift of communication signal, it is possible to be identified as a space-time companion.
With. The system detects that you have a time-space companion with the confirmed patient.
Then, judge that you belong to the space-time partner in the risk group,
The health code will turn yellow.
Persons whose health code is "yellow code" should have two nucleic acid tests within 3 days.
Detection, the interval between two nucleic acid tests must be more than 24 hours.
In particular, if the first test result is negative,
The health code will be briefly changed to "green code" and then changed to "yellow" again.
Code prompts you to conduct a second test as needed. For example, twice
When the nucleic acid test results are all negative, your health code is officially transferred.
This is the "green code".
