(Fighting against New Coronary Pneumonia) China's local epidemic is still running at a high level, the official interpretation of when the prevention and control situation will improve

  China News Agency, Beijing, April 6 (Reporter Li Chun) According to data from the National Health Commission of China on April 6, there were 1,383 new local cases of new coronary pneumonia in mainland China on the 5th, and 19,089 local asymptomatic infections.

At present, the number of newly confirmed local cases and asymptomatic infections in China is growing rapidly, community transmission in some areas has not been interrupted, the epidemic is still running at a high level, and the prevention and control situation is severe and complicated.

  When will the national epidemic prevention and control situation improve?

How to manage the centralized isolation of asymptomatic infected persons?

How to deal with the constantly mutating new coronavirus?

The press conference of the Joint Prevention and Control Mechanism of the State Council on the 6th responded to relevant hot issues.

On April 6, the staff of the Caojiayan Neighborhood Committee was in Lane 199, Zhaohua East Road, registering information for residents before nucleic acid testing and sampling.

Disseminate more and the situation will get better soon

  What are the characteristics of the current epidemic situation in China?

According to Lei Zhenglong, deputy director and first-level inspector of the National Health Commission's Bureau of Disease Control and Prevention, from March 1 to April 5, a total of 176,455 local infections were reported nationwide, affecting 29 provinces. Large-scale epidemics are intertwined with sporadic epidemics, and spillover cases and secondary epidemics are frequent.

  According to media reports on April 6, Tongxin County, under the jurisdiction of Wuzhong in Ningxia, detected a positive person returning from Shanghai to Ningxia.

According to relevant reports, the current round of the epidemic has spread to 30 provinces in China.

  Lei Zhenglong said that since mid-March, with the effective implementation of epidemic prevention and control measures in various places, Guangdong, Shandong, Hebei, etc. have shown a positive trend among the five provinces and cities with severe epidemics before, but the epidemics in Shanghai and Jilin are still on the rise. in a state of development.

  He pointed out that the effective control of the epidemic in many places has proved that strict and strict measures such as isolation, management and control, sealing and control, and screening are taken as the core to deal with the local clustered epidemic caused by the Omicron variant. If necessary, the established policy of "dynamic clearing" can be implemented.

  "The duration of this epidemic situation depends on our prevention and control strategies and the strength of the implementation of prevention and control measures." In the opinion of Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention, insisting on "foreign defense imports, internal defense The general strategy of "rebound" and the general policy of "dynamic clearing", and strictly implement the prevention and control measures in every link, the recent multi-point spread of the epidemic situation will soon improve.

Management of asymptomatic infections requires medical staff

  According to the new version of the new coronary pneumonia diagnosis and treatment plan, patients with mild symptoms and asymptomatic infections need centralized isolation management.

How to ensure their needs for diagnosis and treatment, and timely respond to possible deterioration of the disease?

  "We emphasize that medical personnel must be present when managing asymptomatic infected persons and mild cases, and medical personnel and necessary diagnosis and treatment equipment must be arranged in Fangcang shelter hospitals, including rescue equipment, basic drugs, etc." Peking University First Hospital Infection Wang Guiqiang, director of the disease department, said.

  In March of this year, the Comprehensive Team of the Joint Prevention and Control Mechanism of the State Council issued a management specification for the setting up of Fangcang shelter hospitals, which clearly required Fangcang shelter hospitals to be equipped with a certain proportion of medical personnel, medical testing equipment, rescue drugs and oxygen to ensure that Fangcang shelter hospitals can carry out basic medical conditions. Monitor and treat, with prompt referral when conditions change.

  Wang Guiqiang also pointed out that it is necessary to closely monitor the changes in the condition of all patients, especially those with underlying diseases and older people at high risk of severe illness.

If changes in the condition are found, corresponding treatment measures should be taken in time and 120 vehicles should be contacted to transfer them to designated hospitals for further diagnosis and treatment as soon as possible.

  In this round of local epidemics, the large number of asymptomatic infections is an obvious feature, and the screening of close contacts is particularly important.

Wu Zunyou pointed out that for the detection and management of close contacts, "one must be complete, and the other must be fast."

The timely detection of close contacts of each infected person on the transmission chain is an important measure for early detection.

Be prepared for the emergence of new mutant strains

  The UK Health and Safety Agency recently confirmed that a new variant of the new coronavirus has emerged.

This new variant is a recombination of the Omicron BA.1 and BA.2 branches and is currently named XE.

Two recombinant strains of Delta and Omicron BA.1, XD and XF, were also previously found.

  The WHO also said that existing research shows that the most likely scenario is that the new coronavirus will continue to evolve, but as the body's immunity increases due to vaccination or infection with the virus, the severity of the disease caused by the new coronavirus will change over time. decrease over time.

  "Based on the research on the mutation of the new coronavirus in the past two years, combined with the understanding of viruses such as RNA, we have always believed that the mutation of the new coronavirus is a common event that continues to occur," Wu Zunyou pointed out, "for the emergence of new mutant viruses The plant is ready."

  The expert said that no matter how the new coronavirus mutates, people take normalized prevention and control measures, including the "four early" measures of early detection, early reporting, early isolation, and early treatment, extensive vaccination, wearing masks, washing hands frequently, Personal protective measures such as frequent ventilation and social distancing can effectively control the epidemic.

  "We are also paying close attention to whether the diagnostic reagents can continue to be used for laboratory diagnosis of new mutant strains; whether existing vaccines can prevent infection of new mutant strains, prevent severe illness and death, etc." Wu Zunyou said that these The new understanding provides an important scientific basis for decision-making such as whether to update diagnostic reagents and whether to update vaccines.
