The mobile phone number that collides with the track in an outdoor open space within a certain distance from the same base station within a specified time (for example, 10 minutes or more) is defined as a space-time companion that may be exposed.
For example, the infected person has been to a place within 14 days, and the trajectory of you 14 days intersects with him. Whether it is a physical brush or a drift in communication signals, it may be considered as a problem of time and space.
If the health code turns yellow, citizens should immediately report to their communities (villages) and units. After investigation, if the health code does not belong to the scope of centralized isolation, self-health monitoring will be implemented for 7 days; Under the premise of full protection, go to the designated nucleic acid testing place by yourself and conduct nucleic acid testing free of charge with my health code; Three nucleic acid tests should be conducted within 7 days. If the results are negative, you can apply to the community (village) for cancellation of the yellow code.
After receiving the decoding application, the community (village) conducts a preliminary examination, and submits it to the county (city) level CDC after the preliminary examination, and the county (city) level CDC finds that it meets the decoding conditions for decoding; /kloc-can pass in an orderly manner within 0/4 days with the negative certificate of effective nucleic acid detection within 7 days, but it is still necessary to avoid participating in gathering activities and going to crowded areas such as public places.
If the health code becomes red team, citizens should immediately report to their communities (villages) and units. In principle, we should first isolate and investigate on the spot, and then determine the epidemic prevention management measures after finding out the reasons. The local government that implements local isolation shall organize the implementation of epidemic prevention measures such as nucleic acid detection, which shall be free of charge.
