1) For close contacts, the management measures of "centralized isolation for 7 days+home health monitoring for 3 days" are adjusted to "centralized isolation for 5 days+home isolation for 3 days", during which they are managed by code and are not allowed to go out. On 1, 2, 3 and 5 days, medical observation was concentrated and 1 nucleic acid was detected respectively. On 1 and 3 days, medical observation was isolated at home and 1 nucleic acid was detected respectively.

(two) timely and accurately determine the close contacts, no longer determine the close contacts.

(3) Adjust the "7-day centralized isolation" of overflow personnel in high-risk areas to "7-day home isolation", and assign code management during this period, and do not go out. On day 1, day 3, day 5 and day 7 of home isolation, 1 nucleic acid was detected respectively.

(4) Adjust the risk area from "high, medium and low" to "high and low" to minimize the number of management personnel. In principle, areas where infected people live, work places and activities are frequent and the risk of epidemic spread is high are designated as high-risk areas, and high-risk areas are generally single.

Yuan, the building as a unit, shall not be arbitrarily expanded; Other areas in counties (cities, districts and banners) where high-risk areas are located are classified as low-risk areas. No new infection cases were found in the high-risk area for 5 consecutive days, and it was reduced to the low-risk area. High-risk areas that meet the conditions for unsealing should be unsealed in time.

(5) Employees in high-risk positions who have completed closed-loop operations are adjusted from "7-day centralized isolation or 7-day home isolation" to "5-day home health monitoring". During the period, they were assigned to code management, and 1 nucleic acid detection was carried out on the 65438th, 3rd and 5th days respectively. If they really need to go out, they won't go to crowded public places or take buses.

(6) In epidemic-free areas, nucleic acid testing shall be conducted for risk posts and key personnel in strict accordance with the scope determined in the ninth edition of the prevention and control plan, and the scope of nucleic acid testing shall not be expanded. Generally, the whole staff is not tested according to the administrative area, but only when the source of infection and transmission chain are not clear and the community transmission time is long. Formulate specific implementation measures to standardize nucleic acid detection, reiterate and refine relevant requirements, and correct unscientific practices such as "two inspections a day" and "three inspections a day".
