The BA.5 subclade is becoming a major global epidemic strain
my country's epidemic rebounded in some areas in early July
Mi Feng said at the meeting that at present, the global epidemic continues to rebound, and China's foreign defense import pressure is increasing.
The BA.5 subclade of Omicron is becoming the main epidemic strain in the world, and it has caused a local clustered epidemic in my country, and the prevention and control situation is severe and complicated.
Lei Zhenglong, deputy director of the National Health Commission's Bureau of Disease Control and First-level Inspector, introduced that the BA.5 and BA.4 sub-branches have recently become the main epidemic strains in South Africa, Portugal, the United Kingdom, Israel and other countries; France, the Netherlands, etc. Many European countries and the United States have also seen an increase in BA.5 and BA.4 infections, and the overseas epidemic has rebounded significantly.
Recently, Beijing, Tianjin, Shaanxi and other places have also successively reported local epidemics caused by imported cases of BA.5 mutants, and China's foreign defense import pressure continues to increase.
Specifically in my country, Lei Zhenglong said that in late June, the average number of infections reported every day across the country was less than 40, but the number of infections reported on June 30 exceeded 100.
From July 1 to 7, an average of 325 cases were reported every day, affecting 47 cities in 16 provinces, mainly in Anhui and Jiangsu.
On the whole, the local new crown epidemic in June showed a trend of fluctuation and decline, but the epidemic rebounded in some areas in early July.
The average incubation period of the Omicron variant was shortened to 2 to 4 days
"7+3" control policy is not about relaxing requirements
The ninth edition of the prevention and control plan adjusts the control measures for inbound personnel to "7-day centralized quarantine + 3-day home health monitoring". What is the basis for this adjustment?
Lei Zhenglong said that the average incubation period of the Omicron variant was further shortened, mostly 2-4 days.
At the same time, most of them can be detected within 7 days.
Based on the results of the pilot study and the epidemic prevention and control practices in many places in China, the National Health Commission has optimized and adjusted the isolation and control time for inbound personnel in the ninth edition of the prevention and control plan.
Adjusted the quarantine control time for inbound personnel from the original "14-day centralized isolation medical observation + 7-day home health monitoring" to "7-day centralized isolation medical observation + 3-day home health monitoring".
He said that the optimization and adjustment of immigration control measures is based on sufficient scientific basis, as well as the basis for prevention and control practices.
Regarding the implementation of "7+3" control measures in various places, Lei Zhenglong said that recently, in Shanghai, Jiangxi, Beijing and other places, it was found that individual inbound personnel tested positive after the release of centralized isolation, and national and regional disease control experts carried out Investigation and analysis and risk investigation revealed that there are weak links and hidden dangers in the management of the centralized isolation points for individual inbound personnel, which need to be paid great attention by all localities.
For example, in some places, the frequency of nucleic acid testing for inbound personnel during centralized isolation is insufficient; in some areas, before the inbound personnel are released from isolation, the last nucleic acid test sampling is advanced; in some centralized isolation points, after positive infections are found, there is no evaluation. and investigation of the risk of cross-infection within the isolation point; in some places, the cross-regional movement of inbound personnel after release from isolation has not been implemented in the whole chain management, and the work connection between the entry point and the destination is not smooth; in addition, there are individual immigrants. The personnel did not strictly implement the 3-day home health monitoring after the centralized isolation was lifted, did not take the initiative to report to the society, and even went out to participate in gathering activities during the home health monitoring period.
Lei Zhenglong emphasized that the "7+3" control policy is not to relax requirements, but to require more standardized and stricter management, so that effective prevention and control effects can be achieved.
"Double collection and double inspection" for entry personnel is changed to "single collection and single inspection"
Strengthen the closed-loop management of personnel in high-risk positions at ports
The pressure of foreign import prevention is increasing. How to prevent overseas import from causing local epidemics?
Li Zhengliang, deputy director of the Department of Health and Quarantine of the General Administration of Customs, said that the customs will further optimize the work process on the basis of strictly doing a good job in epidemic prevention and control at ports.
The first is to optimize the sampling and testing of inbound personnel.
The original sampling and testing requirements of "dual collection and double inspection" for entry personnel have been optimized to only oropharyngeal swab "single collection and single inspection". The upper respiratory tract specimens are collected through the tube, and the nasopharyngeal swabs are no longer collected; the requirements for blood sample testing for new crowns for entry personnel are cancelled.
The second is to optimize the proportion of inbound cargo aircraft boarding and deployment.
The third is to optimize and improve the prevention and control measures of the new crown pneumonia epidemic of imported goods.
The fourth is to optimize the closed management system for staff in high-risk positions in the customs.
Lei Zhenglong also said that in the face of the severe and complex epidemic situation, the comprehensive team of the Joint Prevention and Control Mechanism of the State Council has deployed various places to further strengthen the import work of foreign defense, requiring the closed-loop management of personnel in high-risk positions at ports, and the prevention of risks such as inbound items and passenger aircraft. , strengthen the isolation and control of inbound personnel, and strengthen epidemic prevention and control in port cities.
