Original title: Adhere to the “dynamic reset” epidemic prevention goal, Chinese officials explain why they did so

In the autumn and winter seasons, the new crown epidemic in China has spread in many places, and discussions on China’s “dynamic zeroing” policy have been raised from time to time. Some people hold a positive attitude and believe that the cost of implementing this policy is acceptable; some people advocate abandoning “dynamic zeroing” and believe that the cost of implementing this policy is too high. Recently, officials have responded positively to this discussion on multiple occasions.

Officials have proposed to insist on “dynamic reset” on many occasions

On November 13, at a press conference on the Joint Prevention and Control Mechanism of the State Council, Mi Feng, spokesperson of the National Health Commission and Deputy Director of the Propaganda Department, stated that the general strategy of “external defense input and internal defense rebound” must be adhered to. , Adhere to the epidemic prevention goal of “dynamic reset”, achieve early detection, rapid disposal, precise control, and effective treatment to ensure that the epidemic does not appear to be imported and rebounded on a large scale.

In an interview with Xinhua News Agency, Liang Wannian, head of the expert group of the National Health Commission’s New Coronary Pneumonia Epidemic Response and Handling Work Leading Group, said that the goal of epidemic prevention and control in the current normalization stage is not “zero infection”, but “dynamic clearing”, that is, the epidemic. If you find one, put it out together. In the normalized prevention and control phase, early detection, early diagnosis, early isolation, and early treatment should be carried out to the greatest extent, so as to resolutely prevent the continuous spread of the epidemic in the community.

On the afternoon of November 6, the Associated Press reporter at the press conference of the Joint Defense and Joint Control Mechanism of the State Council also asked whether China would consider abandoning the “zero tolerance” policy. In response, Wu Liang, deputy director of the CDC of the National Health Commission, responded that the current global epidemic, especially the epidemic in neighboring countries in my country, has repeated ups and downs and remains high. The situation of epidemic prevention and control this winter and next spring is complex and severe. We will continue. Adhere to strict epidemic prevention and control measures, build a solid barrier of “external defense input, internal defense rebound”, and consolidate the hard-won results of prevention and control.

On November 5th, the State Council’s Joint Prevention and Control Mechanism Comprehensive Team held a video and telephone conference. Ma Xiaowei, the leader of the State Council’s Joint Prevention and Control Mechanism Comprehensive Team and Director of the National Health Commission, emphasized that it is necessary to keep the soil and be responsible, maintain strategic determination and persistence. The epidemic prevention goal of “dynamic reset” resolutely consolidates the hard-won results of prevention and control.

At this meeting, Ma Xiaowei also stated that we must adhere to the general strategy of “external defense input, internal defense rebound”, and resolutely overcome paralysis, war exhaustion, fluke psychology, and relaxation mentality, and we must not let the hard-won prevention and control results go to waste. .

China’s adherence to the epidemic prevention goal of “dynamic reset” can be traced back to the end of the Wuhan epidemic.

On May 8, 2020, the State Council’s Joint Prevention and Control Mechanism issued guidance on the normalization of the prevention and control of the new crown pneumonia epidemic. At that time, it was proposed that the prevention and control of the new crown pneumonia epidemic in my country should be further consolidated. The state becomes normalized. The guidance clearly requires the full implementation of the overall prevention and control strategy of “external defense input, internal defense rebound”, and insist on timely detection, rapid disposal, precise management and control, and effective treatment.

In the second half of 2020, Zhang Wenhong, director of the Department of Infectious Diseases of Shanghai Huashan Hospital, also analyzed and interpreted my country’s “dynamic zeroing” strategy on multiple occasions. On July 19, 2020, Zhang Wenhong analyzed the differences in prevention and control strategies between Hong Kong and Xinjiang on his personal Weibo on the new cases that occurred in Hong Kong and Xinjiang. At the same time, he said that from the experience of Beijing and Urumqi, our The rapid response, precise prevention and control, and “dynamic reset” prevention and control measures taken have been able to ensure that the local area basically returns to normal life after 3-4 weeks. And this is definitely the best solution for our country at present.

Why insist on “dynamic reset”?

Entering autumn and winter, my country’s current round of local new crown epidemic has spread to 21 provinces across the country, with 1,379 cases of infection. Although the spread caused by the delta mutant strain is spreading rapidly, the epidemic prevention and control are carried out through the orderly implementation of nucleic acid testing in the areas where the epidemic occurs, rapid screening of populations at risk locations, strengthening the isolation and control of key personnel, and paying close attention to medical treatment and infection prevention and control. The effect was quickly revealed.

“The epidemics in Shaanxi, Inner Mongolia, Gansu, Qinghai, Ningxia, Hubei, Hunan, Shandong, Jiangsu, Zhejiang, Guizhou, Chongqing and other provinces (autonomous regions and municipalities) are basically controlled within an incubation period.” November 13, National Health Wu Liangyou, deputy director of the Disease Control Bureau of the Health Commission, said at the press conference.

If the dynamic reset strategy is abandoned, what state will the local new crown epidemic enter? This may be the answer from the experience of some countries.

In fact, starting from August 10 this year, Singapore has begun to coexist with the virus, and plans to gradually open up its economic, social and tourist activities in four stages. On October 9, Singapore’s Prime Minister Lee Hsien Loong delivered a national speech, stating that considering the contagiousness of the Delta variant, the “clearing” strategy is no longer feasible, and stressing the importance of reopening the border and the “coexistence with the virus” strategy.

What is the response to the Singapore epidemic after abandoning the zero-clearing strategy for three months? On November 12, the Ministry of Health of Singapore announced that there were 2,396 newly confirmed cases and a total of 506 deaths. On August 10, the cumulative number of confirmed cases of new crown in Singapore was 65,890. Three months later, the number of confirmed cases increased by 130,000. In three months, the cumulative number of new crown deaths in Singapore has also increased from 42 to 506.

Zhang Hongtao, an associate professor at the University of Pennsylvania School of Medicine, who has long been concerned about the global fight against the epidemic, analyzed Singapore’s epidemic prevention and control strategies in an interview with The Paper. He believes that after the opening of Singapore, with the increase in the number of infections, even if the proportion of severe cases is not large, the hospital is hospitalized. The number of patients and ICU patients will definitely increase, and there is a risk that medical resources will be run on quickly. This is the consequence of abandoning the “zero clearing” policy, and Singapore has a full understanding of this.

If China abandons the “dynamic reset” strategy and faces the highly contagious delta mutant strain, how many people will be infected in China? According to data from the Real-Time Evaluation of Community Transmission in the UK (REACT), the current infection rate of the Delta variant is 1.72%. If calculated based on this infection rate, there will be more than 24 million people at risk of infection in China without the “dynamic reset” strategy.

“Even if China’s new crown is reduced to’flu level’, if the scale of infection is too large, it is also a great risk for China.” Zhang Hongtao said in an interview with The Paper before that China is different from other countries, even if it is a common cold, everyone I also have the habit of running to the hospital and getting IV drips. Even after the vaccination rate reaches herd immunity, if everyone cannot change their attitude towards the new crown, then once an epidemic occurs after the opening, the hospital is likely to be run on.

  In response to questions about the “low cost-benefit ratio” of epidemic prevention and control measures in some key areas of my country, Liang Wannian responded in an interview with Xinhua News Agency recently that through the “dynamic zeroing” strategy, my country was able to quickly and effectively reduce infection and mortality. In the short term, it may have a certain impact on the daily life of the infected and close contacts, but in the long run, the rapid control of the epidemic will help the economic and social life to quickly return to normal.
