On October 13, The State Council’s Joint Prevention and Control Mechanism held a press conference to introduce the relevant situation of scientific and accurate epidemic prevention and control.
National Health Commission spokesperson Mi Feng said at the meeting that the current global epidemic is still at a high level. The local clustered epidemic in my country is characterized by "many points, wide areas, and frequent occurrence", and the prevention and control situation remains severe and complex.
must unswervingly adhere to the overall strategy of "preventing imports from outside and preventing rebound from inside" and the general policy of "dynamic zeroing", strictly follow the ninth edition of the prevention and control plan and the requirements of the "nine prohibitions", implement the "four-party responsibilities" of local, departments, units and individuals, and use fast to control the spread of the epidemic, firmly maintain the bottom line of preventing large-scale epidemics, and minimize the impact of the epidemic on economic and social development.
01.
The current national epidemic situation is severe and complex, but overall controllable
Lei Zhenglong, Director of the Department of Defense of the National Bureau of Disease Control and Prevention, introduced that Recently, my country has continued to face the dual risks of imported epidemics from abroad and the spread of local epidemics, and the epidemic in some areas has rebounded .
Xinjiang epidemic has recurred, but overall it is controllable. The epidemic situation in Inner Mongolia has improved significantly, and the number of cases has dropped significantly. The epidemic situation in Sichuan, Gansu, Shanxi and other places has gradually been controlled. The epidemic situation in Ningxia and Tibet is stable and improving, and the epidemic situation in other provinces is spreading at multiple points. The current national epidemic situation is severe and complex, with many points, wide range and frequent occurrence. The risk of local clustered epidemics in still exists, but the overall controllable is .

Why does my country insist on " dynamically clear "? Experts responded that at the press conference of
, Liang Wannian, head of the expert group of the National Health Commission's leading group for epidemic response and disposal, responded from five aspects.
▶ Liang Wannian first explained the concept and core connotation of "dynamic zeroing". He introduced that the overall policy of "dynamic zeroing" implemented by the Chinese government is based on the anti-epidemic concept of "people first, life first". Each country’s anti-epidemic policies and anti-epidemic strategies are proposed based on the anti-epidemic concept. "dynamic zeroing" is our country's overall policy for fighting the epidemic. The core of this general policy is to block the epidemic, rather than eliminate the virus, nor does it not allow a single case.
Liang Wannian introduced that the core of blocking the epidemic is to quickly discover and extinguish quickly, discover and extinguish together. The core of "dynamic zeroing" is to block the continuous community transmission of the epidemic and prevent the epidemic from forming a large-scale epidemic or rebounding of large-scale epidemics.
achieves "dynamic zeroing". The two keywords are the most important. One is "fast", quickly discover and deal with it quickly; the other is "precise", accurately identify the epidemic, accurately define the scope of the epidemic area, accurately conduct epidemiological investigations, accurately conduct close contacts , accurately determine and manage , and accurately carry out clinical treatment, and ultimately accurately balance epidemic prevention and control and social and economic development.
▶ Second, there are two different perspectives to measure the harm of an epidemic. The internationally common perspective of public health is to measure it from the perspective of the group, using indicators such as mortality and excess mortality, rather than from the perspective of case mortality and individual. is indeed declining for Omickron mutant compared with previous mutant strains and original strains. However, due to its fast transmission speed, more hidden transmission, and gradually increasing immune escape, the overall incidence rate is high, which means that there will be a large number of infections in the population.Multiply the number of infections by individual mortality rate, the number of deaths will be relatively large, and the group mortality rate will be higher than influenza , and no lower than the original and other mutant strains. It can be seen that its harm to humans has not decreased significantly overall. This is an important indicator for World Health Organization and various countries to judge its harm.
In addition, the excess mortality rate, that is, after the emergence of this disease, it will not only affect the severe illness and death of these patients infected with this disease, but it may lead to a run of medical resources. Once the medical resources of are run, it will affect the demand for other normal medical services, which may lead to some unnecessary deaths under normal conditions. Scientifically, measuring this additional death caused by the impact of the epidemic can be called "excess death". Judging from the current situation, the excess death caused by the new crown pneumonia epidemic is relatively high, whether it is the original strain or the previous mutant strain, especially the Omickron mutation. After research, it is more than 100 parts per 100,000.
▶ Third, the total population of our country is large, the proportion of the elderly population of is high, and there are also a large number of patients with underlying diseases. These people are high-risk groups for the new coronavirus infection, and the probability of getting severe illness or even dying after infection is higher than that of the general population . Coupled with the effect of prevention and control in the past period, the overall infection rate of the new coronavirus in my country is low, and the natural immunity obtained is not strong. Although we have obtained a certain amount of immunity through immunization, the escape of the new mutant strain to this immunity is strengthening. Therefore, if we relax and do not "dynamic zero", it will inevitably cause a large number of infections, leading to the elderly and people with underlying diseases, which may cause a large number of severe illnesses and even a large number of deaths. This large number of severe illnesses and large amounts of death cannot be tolerated, so we must try our best to protect ourselves.
▶ Fourth, now scientifically, the direction in which the mutation of the new coronavirus will change in the future? After the mutation, its virulence, pathogenicity, and harm still cannot be fully grasped. But there is one thing that the scientific community is sure of, this virus will always change, and changing is its normal state. In addition, the Omickron variant strain is definitely not the last variant of the new coronavirus, and there is great uncertainty. In this case, we adhere to the existing prevention and control strategies and adhere to the overall policy of "dynamic zeroing". Our prevention and control in the past three years has proved that it is effective, feasible and scientific. Therefore, in the face of these uncertainties, we should use deterministic strategies and deterministic policies to combat this uncertainty .
▶ Fifth, we must consider the long-term harm of this disease. Now internationally, scientists from all over the world are very concerned about and worried about the sequelae after infection with . Studies have shown that a certain proportion of infected people will experience various sequelae such as fatigue, dyspnea, neurocognitive disorders, etc. does not fully understand the pathogenic mechanism and final duration of this condition in science. Unlike general influenza and known diseases, the sequelae and related conditions in science are clear about its sequelae. There is still a lot of unknowns in the new crown .
Based on the above considerations, China currently adheres to the overall policy of "dynamic clearance". How long does
03.
need to return to normal production and life? Experts responded to
Everyone is looking forward to the epidemic ending as soon as possible and return to normal production and life as soon as possible. How long will it take for us and what full preparations need to be done?
In this regard, Liang Wannian said that we all hope that the epidemic will end as soon as possible and return to a normal life like before 2019. Overall, our epidemic prevention and control has achieved phased results. We have seen the dawn of victory, but we have not yet reached the other side of victory. We still need to continue to work hard to do the corresponding prevention and control work.In the end, the epidemic will be completely over or we will completely overcome the epidemic. We need to comprehensively consider the variation of this virus, the infection spectrum of the disease, the changes in severity, and the resistance of the health system, including our prevention and control capabilities, treatment capabilities, and social public health intervention measures. We are in this window period now, and there are several tasks that need to be done further:
◎ First, we must strengthen our confidence and unify our thinking. It is very important to adhere to our overall strategy and policy. Seize this "window period", and we will persist again, and we will win. Persistence will definitely win. Confidence may be more important than gold. This is very important.
◎ Second, we must strengthen vaccination, especially vaccination for the elderly, to prevent severe illness and death.
◎ The third is to strengthen the construction of prevention and control and treatment capabilities and corresponding preparations. For example, to prevent hospital resources from being run, how can we quickly control and supply some protective equipment under a large-scale epidemic?
◎ Fourth, we should give full play to the role of science and technology, and we should increase efforts in the research and development, production and supply of more effective vaccines and more effective, accessible and simpler drugs. Now we have seen some hope in medicine.
◎ Fifth, make good preparations for corresponding materials, including the reserves of epidemic prevention and control materials, and also materials to ensure normal production and life.
◎ Sixth, emphasize speed and accuracy, emphasize prevention of "one-size-fits-all" and preventing the phenomenon of "adding layer by layer".
If these are combined and we have firm confidence, we will definitely be able to ultimately defeat the epidemic.
04.
For schools and catering outside the risk area, resolutely avoid "close the gap"
Mi Feng said that we must resolutely rectify the "adding of the layers" and care for the people affected by the epidemic, and effectively guarantee their lives and medical needs.
Lei Zhenglong said that we must continuously improve the scientific and accurate level of epidemic prevention and control. requires all localities to speed up precise epidemic investigations. The epidemic prevention and control cannot be simplified, risk areas cannot be delineated on a large scale, and "silence" cannot be replaced by control. should timely and accurately define medium and high-risk areas, take resolute and decisive control measures in a timely manner, and make dynamic adjustments according to changes in the epidemic situation. Those who meet the conditions for unblocking should be unblocked in a timely manner to facilitate people's lives and travel. strengthens epidemic monitoring for schools, catering and other units outside the risk area, resolutely avoids "one-up" and minimizes the impact of the epidemic on economic and social development.
05.
will continue the prevention and control policies around the Mid-Autumn Festival and National Day?
Lei Zhenglong introduced that the mobility of personnel has increased during the Mid-Autumn Festival and National Day, and the risk of epidemic transmission is high. On the basis of deploying the comprehensive implementation of the ninth edition of the prevention and control plan, the State Council’s joint prevention and control mechanism has strengthened a series of prevention and control policies and measures, such as advocating safe and orderly travel of the general public, promoting on-site inspections, checking for effective nucleic acid test negative certificates in key places and institutions, and reducing unnecessary gatherings.
National Health Commission will organize an evaluation of the role of these measures in detecting, controlling the epidemic as soon as possible, and preventing a large-scale rebound of the epidemic. Next step will, on the premise of adhering to the overall policy of "dynamic zeroing", on the basis of evaluating the effectiveness of the measures, combined with factors such as domestic and international epidemic prevention and control situations and virus mutations, continue to improve and optimize epidemic prevention and control policies, and coordinate epidemic prevention and control and economic and social development.

BF.7 sub-branch has strong transmission capabilities. Whether it can become a global dominant epidemic strain remains to be observed
Chinese Center for Disease Control and Prevention virology chief expert Dong Xiaoping introduced that the BF.7 sub-branch is actually the abbreviation of BA.5.2.1.7, and is a derivative branch of the Omickron BA.5 variant strain.Since the evolutionary branch of
BF.7 has gradually become a common strain in many countries, with the global share increasing from about 3.5% in late September to about 11% last week. Similar to some other Omickron evolutionary branches such as BA.2 and BA.5 when they first appeared, the BF.7 sub-branch has shown strong transmission capabilities. Whether it can become the next dominant epidemic strain worldwide needs further observation. The evolutionary branch of BF.7 did not show any significant changes in pathogenicity .
07.
6The sequelae of new crown is wide, and the symptoms can last for several weeks or even longer
Wu Zunyou said that the sequelae of new crown is also called the long-term symptoms of new crown. The clinical definition given by the World Health Organization in October 2021, the sequelae of new crown usually occurs within 3 months after the onset of the new crown infection. It can be that certain new symptoms appear after recovery from acute infection, or some symptoms persist during the original acute infection period. The symptoms of last for at least 2 months and can occur repeatedly and cannot be explained by other diagnoses.
According to global research results, the health problems with the wide coverage of the sequelae of the new crown are health problems, including fatigue or fatigue, difficulty thinking or inability to concentrate, shortness of breath or difficulty, headache, dizziness, accelerated heartbeat, chest pain, cough, joint or muscle pain, depression or anxiety, fever, loss of smell or taste, etc. . These symptoms can last for weeks, months, or even longer.
The sequelae of the new coronavirus is common in severe cases, but it can also occur in mild cases. People who have been vaccinated have a lower risk of sequelae after contracting the new crown than those who have not been vaccinated. Wu Zunyou said that the best way to prevent the sequelae of the new coronavirus in is to prevent the new coronavirus infection.
