What is space-time contact?

14 days, in the same space-time grid with the confirmed patients (usually 800 m× 800 m as the detection range) and people who are together for 10 minutes.

Generally speaking, the infected person arrives somewhere within 14 days, and your trajectory intersects with him within this 14 day. Whether it is through the body or drifting on the communication signal, it can be considered as time and space. Experts said that screening "time-space partners" can maximize the discovery of potential risk groups, and include more "time-space overlap" and people who may be infected in key investigations, truly opening the door to early detection and early prevention and control.

Matters needing attention of space-time companion

It should be noted that "time-space companions" need not be overly nervous, but should actively cooperate with various epidemic prevention measures, do a good job in psychological construction, and actively cooperate with prevention and control, without being overly nervous. I'm not sure if my space-time companion will be infected.

It's best not to see a doctor by yourself. According to the prevention and control regulations, the relevant control personnel will be in place soon after receiving the notice, and the next epidemic prevention measures will be arranged. During the period before the arrival of prevention and control personnel, self-isolation should be done. If possible, it is best to isolate a single room at once and not live with your family.
