Closed-loop management of high-risk groups refers to close contacts, sub-close contacts, overlapping time and space trajectories, "simultaneous space" companions, people in medium and high-risk areas, and people in global closed-loop management areas (people who are in direct contact with entry personnel, goods and environment at land ports; Cross-border transportation department, cleaning, maintenance and other personnel.
Port loading and unloading personnel for imported goods; Customs and entry-exit administration departments directly contact the entry-exit personnel and front-line personnel who import cold-chain goods, as well as the staff in centralized isolation places, designated medical institutions, fever clinics, etc.), and carry out home health monitoring and code management for 5 days, and carry out 1 nucleic acid testing on 1, 3 and 5 respectively. Do not go out unless necessary, and do not go out to crowded public places or places.
Employees in high-risk positions who have completed closed-loop operations (front-line workers importing cold chain goods, workers in centralized isolation places, designated medical institutions and Huang Ma hospitals) shall be subject to home health monitoring for 5 days, during which code management shall be implemented. 1, 3, 5 days respectively 1 nucleic acid detection, do not go out unless necessary. If they really need to go out, they won't go to crowded public places or take buses.
Five situations were adjusted, and most of the centralized isolation was adjusted to home isolation, and the centralized isolation time was shortened accordingly. At present, the mutant in COVID-19 has a fast transmission speed and a short incubation period, and the shortest time from infection to transmission is only 24 hours, so isolation is the key, including centralized isolation and home isolation.
Close contacts: the management measures of "7-day centralized isolation +3-day home health monitoring" were adjusted to "5-day centralized isolation +3-day home isolation"; Overflow personnel in high-risk areas were adjusted from "7-day centralized isolation" to "7-day home isolation".
Entry personnel: "7 days of centralized isolation +3 days of home health monitoring" was adjusted to "5 days of centralized isolation +3 days of home isolation". It is the employees in high-risk positions who end the closed-loop operation: "7-day centralized isolation or 7-day home isolation" is adjusted to "5-day home health monitoring". As can be seen from the above adjustments, centralized isolation is reduced and home isolation is increased. The cost of isolation is reduced, but the effect of isolation is not weakened.
