What does it mean that time and space are accompanied by an epidemic?

Recently, 82,000 "time-space companions" in Chengdu have gone on a hot search. After Chengdu, citizens in Zhengzhou, Changsha and other places also received relevant text messages. As a result, a romantic new term "time-space companion" appeared in front of the public.

The so-called epidemic accompanied by time and space refers to the COVID-19 infection caused by the coincidence, crossing and accompanying of time and space by strangers without intersection. For example, a patient recently went to a place, and you happened to go to a place at this time. You two don't know each other, maybe you just passed by, and both of you may be considered as time-space coincidence or time-space companionship because of a patient. At present, the recognized space-time partner and the diagnosed person appear in the same grid, with the range of 800 m * 800 m. * * * The same stay time exceeds 10 minute, and the cumulative stay time of either party exceeds 30 hours in the last 14 day. Your green health code will turn into a yellow code. And will be marked as a time companion. And the statistics and source of these data is your own mobile phone number.

In view of the current epidemic situation, in order to ensure everyone to spend this winter safely, when your mobile phone's green health code is changed to yellow code, don't be too nervous, actively cooperate with the inspections required by the epidemic prevention department, and do nucleic acid tests twice within 72 hours after receiving the SMS prompt. Don't shut down the network to avoid being detected by big data. For the health of ourselves and others, we should actively respond to the requirements of the epidemic prevention department, obey the instructions and tide over the difficulties together.
