  "Most of the Omicron variants can be detected within 7 days." At the press conference of the State Council's Joint Prevention and Control Mechanism on June 28, Wang Liping, a researcher at the Communication and Prevention Division of the China Center for Disease Control and Prevention, said that based on this, "New Coronavirus The Virus Pneumonia Prevention and Control Plan (Ninth Edition) has optimized the time limit and method of isolation and control of persons at risk related to the epidemic.

  On the same day, the Comprehensive Team of the Joint Prevention and Control Mechanism of the State Council released the full text of the "New Coronavirus Pneumonia Prevention and Control Plan (Ninth Edition)" on the official website of the National Health Commission. The delineation standards, etc. have been adjusted.

  The isolation and control time limit is shortened, and the plan adjustment is optimization rather than relaxation

  Wang Liping introduced that the ninth edition of the prevention and control plan adjusted the isolation and control time for close contacts and inbound personnel from "14 days of centralized isolation medical observation + 7 days of home health monitoring" to "7 days of centralized isolation medical observation + 3 days of home health monitoring". , the nucleic acid testing measures were adjusted from "nucleic acid testing on the 1st, 4th, 7th, and 14th days of centralized isolation medical observation, collecting nasopharyngeal swabs, and double sampling and double testing before release from isolation" to "centralized isolation medical observation 1, 2, 3, Nucleic acid testing on days 5, 7 and on the third day of home health monitoring, collection of oropharyngeal swabs”, and double sampling and double testing will not be carried out before the release of centralized isolation medical observation.

The close control measures have been adjusted from "7-day centralized isolation medical observation" to "7-day home isolation medical observation", and nucleic acid testing on the 1st, 4th, and 7th days.

  "The ninth edition of the prevention and control plan is an optimization and adjustment of prevention and control measures. It is not to relax prevention and control, but to require higher, more standardized, more accurate, and faster." Deputy director of the National Health Commission's Bureau of Disease Control, first-level inspection Officer Lei Zhenglong introduced that the key to the implementation of the new version of the prevention and control plan is to control the key risks that should be controlled, implement the implementation in place, and resolutely cancel those that should be cancelled, so as to further improve the scientificity and accuracy of epidemic prevention and control. Make full use of resources, improve the efficiency of prevention and control, and coordinate epidemic prevention and control and economic and social development.

  The new version of the plan encrypts the frequency of nucleic acid testing for high-risk occupational groups, and adds antigen testing as a supplementary means of epidemic monitoring in primary medical and health institutions.

The new version of the plan also adds drug monitoring requirements, which means that after the local epidemic occurs, people who purchase antipyretic, cough, antiviral, antibiotics, colds and other drugs need to register with their real names, which is convenient for urging drug users to carry out timely testing.

  At the same time, the plan also clarifies regional nucleic acid detection strategies in different scenarios. For provincial capital cities, cities with a population of more than 10 million, general cities, and rural areas, the start and termination conditions of regional nucleic acid detection and the corresponding nucleic acid after the outbreak are clarified respectively. detection strategy.

  Be wary of imported and spread abroad, the branch of Omi Kronya may trigger a new round of epidemics

  Internationally, the main epidemic strains of the new coronary pneumonia epidemic are still evolving.

According to Wang Wenling, a researcher at the Institute of Viral Diseases of the Chinese Center for Disease Control and Prevention, on May 18, the World Health Organization listed the subclades of the 6 Omicron variant strains as "the evolutionary clade of the variant strains of concern under monitoring." The top three Omicron sub-branches are BA.5, BA.2 and BA.4, and the proportion of BA.5 has shown a rapid upward trend recently.

BA.4 and BA.5 have become the main epidemic strains in South Africa, Portugal, the United Kingdom, Israel and other countries; recently, France, the Netherlands and other European countries and the United States have also seen an increase in BA.4 and BA.5 infections.

Some experts predict that the world may face a new round of epidemics caused by BA.4 or BA.5 this summer.

  Preliminary research results show that the transmissibility and immune evasion ability of the new coronavirus Omikron variants BA.4 and BA.5 are slightly enhanced, the difficulty of prevention and control will increase, and China's foreign defense input pressure will increase.

"We must be highly vigilant about the importation and spread of Omicron BA.4 and BA.5 from abroad. Recently, BA.4 and BA.5 have been found in imported cases abroad, and the number of infected people is still increasing." Lei Zhenglong said.
