The implementation of "Category B B control", the new coronavirus infected persons will no longer implement isolation measures, no longer determine the close contacts; no longer delineate the high and low risk areas; no longer take quarantine infectious disease management measures for entry into the personnel and goods.
The implementation of the "Type B B management" is by no means a liberalization, focusing on strengthening services and protection. To grasp the preparation of medical treatment resources, efforts to do a good job of the public demand for medication, to do a good job of the elderly, children and other key groups of protection and treatment, especially to strengthen the elderly vaccination and health management, and effectively strengthen the prevention and control of epidemics in rural areas.
The implementation of the "B B tube" still needs the support and cooperation of the general public. We must continue to adhere to the good personal hygiene habits and healthy lifestyles that we have developed over the past three years, and always do a good job of personal protection.
In terms of identifying sources of infection, the main way to identify infected persons during the "Category B A" period was through the "exhaustive testing" of occupational groups at risk, and nucleic acid screening of all persons in risk areas. After the implementation of "Category B Regulation B", infected persons will be detected mainly through consultation at medical institutions, self-surveillance of residents' health, and testing of key populations. All localities should ensure that the community retains a sufficient number of convenient nucleic acid testing points, to ensure that retail pharmacies, network sales e-commerce to ensure that there are sufficient antigen test reagents to meet the demand for testing residents.
In the management of infectious sources, "Category B A control" when the discovery of infected persons and not excluded suspected cases to implement isolation and treatment measures. At the same time, close contacts to carry out epidemiological investigations and isolated observation. After the implementation of "Category B B control", the discovery of asymptomatic infected persons and mild cases of home health management.
In terms of prevention and control in the community, after the adjustment from "Category B, A" to "Category B, B", the prevention and control measures in the community focus more on key places, key institutions and key populations, and cancel or reduce restrictions on the activities of institutions and people in other places to minimize the impact on the public. Restrictions on the activities of other establishments and people are eliminated or reduced to minimize the impact on the normal production and life of the public. In addition to nursing homes, social welfare institutions, these special institutions, no longer check the nucleic acid negative certificate, and no longer on the cross-regional flow of landing inspection, and no longer on the spillover risk of people to carry out cross-regional co-inspection, no longer delineate high-risk, low-risk areas, and no longer to take the high-risk areas, "do not leave the house, door-to-door service," and other risk management and control measures.
In terms of sanitary quarantine at the border, after the implementation of "Type B B control", the entry of people no longer implement closed-loop transit, centralized isolation and other measures. People coming to China in accordance with customs requirements, fill out a health declaration card, declare normal and customs port routine quarantine without abnormalities can be directly into the social surface, the entry of goods no longer take preventive disinfection, the import of cold-chained food is no longer sampling.
