The relevant person in charge of the epidemic prevention and control command center in Yuecheng District got the answer: "At present, after the unified judgment of the whole province, people who may have the risk of crossing the track with COVID-19 positive cases in time and space are all included in the' yellow code' management category."
The person in charge said that the public need not be too nervous when the health code changes to Huang Shi. For citizens in doubt, the staff will conduct telephone verification in time. If there is no intersection with positive cases or high-risk areas in COVID-19, and the nucleic acid test is negative, the normal green code can be restored.
What is "time and space companionship"?
At present, time-space coincidence, time-space accompaniment and time-space intersection are all interpreted as a term. Although the specific definitions vary from place to place, they are all similar. This concept can find the potentially dangerous population as much as possible, and bring more people who may be infected because of "time-space coincidence" into epidemiological monitoring.
For example, the patient has been to a certain place within 14 days, and the trajectory of you 14 days intersects with him. Whether it is a physical passing or a drift in communication signals, it may be considered as a coincidence of time and space, or a concomitant of time and space.
What is a "time companion"?
"Time-space companion" refers to my telephone number, which has been verified by COVID-19 epidemic prevention and control system to be related to the confirmed case. If I have the status of space-time companion, my green health code will turn into a yellow code with warning nature, and will be marked as "space-time companion" by the system.
