Do space-time partners need isolation?

Simple space-time companions don't need centralized isolation. After the appearance of yellow code, space-time companions usually monitor at home for 7 days and detect nucleic acid twice.

After receiving short messages from people with overlapping empty tracks, you should report to your community, Committee, unit, hotel, etc. As soon as possible. The two nucleic acid tests should be carried out within 3 days with an interval of 24 hours. Don't go out for a while until you get a negative result. Finally, the result of nucleic acid test is negative, so there is no need for separation. If the nucleic acid test results are positive, centralized isolation will be required.

The detected number is a spatio-temporal adjoint number, and there is a certain probability that it is a virus carrier, but this probability is not completely 100%. We need two nucleic acid tests to know whether we are infected with the virus. After the test results come out, we can apply to change the health code back to green and end the isolation.

Brief introduction of "space-time companion"

According to the experts of disease control, a time-space companion refers to a citizen whose phone number stays in the same time-space grid (800 m× 800 m) for more than 10 minute, and whose phone number stays in the time-space grid for more than 30 hours in the last 14 days.

Generally speaking, the confirmed patient has been somewhere within 14 days, and the trajectory of you 14 days intersects with him. Whether it is physical transmission or drift of communication signals, it may be considered as a problem of time and space.
