Do family members receive short messages at the intersection of time and space, and do other family members need to do nucleic acid testing?

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.

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.

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.
