Do time and space overlap need centralized isolation?

Space-time partners need to be isolated. Spatio-temporal companionship refers to staying 14 days and * * * staying 10 minutes in the same spatio-temporal grid (800 m× 800 m) with the diagnosed patient. Time and space companions need to report to the community in time, do nucleic acid twice every three days, and take personal protective measures.

Report to the community in time: after receiving short messages from people with overlapping empty tracks, report to the community, committees, units, hotels, etc. Go to your place as soon as possible.

Conduct two nucleic acid tests within 3 days: after receiving short messages from people with overlapping empty tracks at the same time, conduct two nucleic acid tests within 3 days with an interval of 24 hours, and don't go out until you get negative results.

Personal protective measures: after receiving short messages from people with overlapping empty tracks, you should immediately check the nearest nucleic acid testing institution online, and then immediately put on a mask and go to the testing point for nucleic acid testing. In the meantime, don't go to places with heavy traffic, and don't take public transportation such as buses, subways and taxis.
