What's the difference between 2+ 12 and 7+7?

The days of centralized isolation are different with different isolation points.

7+7, according to the regulations, if the entry personnel who have a fixed residence in this city and meet the conditions of home isolation health observation apply for home isolation, they can be closed-loop transferred from the centralized isolation point to the residence on the eighth day to carry out 7-day home isolation health observation. Prior to this, all immigrants were quarantined 14 days. 2+ 12, "2" means. Closed management within 2 days, that is, stay indoors and conduct nucleic acid detection twice, with an interval of more than 24 hours. "12" refers to 12 days of strict community management, during which relevant personnel are required not to go out unless necessary. If you want to go out, wear a mask for personal protection, and don't attend or go to gathering places. At the same time, cooperate with the implementation of interval nucleic acid detection to do daily independent health monitoring.

Reation Wu, vice president of Fudan University School of Medicine, introduced the following. 14 days, 7+7, 2+ 12, which is the control regulation of "three circles" around confirmed cases and close contacts, sub-close contacts and risk groups. At present, all close contacts are isolated 14 days, the second close contact is isolated for 7 days, and the community monitors itself for 7 days. "2+ 12" is aimed at the risk groups in the building or workplace where the cipher connector is located. At present, it only takes 14 days to carry out self-health management for people involved in the workplace.
