Liang Wannian, head of the expert group of the National Health and Family Planning Commission's epidemic response and disposal leading group, said that, on the whole, our epidemic prevention and control has achieved initial results, and we have seen the dawn of victory, but we have not yet reached the other side of victory. "We still have to continue to work hard to do the corresponding prevention and control work. In the end, when the epidemic is completely over or we completely overcome the epidemic, we need to comprehensively consider the variation of the virus, the change of infection spectrum and disease severity, the resistance of the health system, our prevention and control capabilities, treatment capabilities, and social public health interventions. "
He said that we are now in this window period and there are several tasks that need to be further done.
First, we should strengthen our confidence and unify our thinking at present. He said that it is very important to adhere to our grand strategy and policy and seize this "window period". "If we stick to it, we will win. If we persist, we will win. Confidence may be more important than gold. This is very important. "
The second is to strengthen vaccination, especially for the elderly, to prevent serious illness and death.
The third is to strengthen the capacity building of prevention, control and treatment and corresponding preparations. "For example, to prevent medical resources from being squeezed out, how to quickly control and meet the supply of some protective equipment in a large-scale epidemic?"
Fourth, give full play to the role of science and technology and increase efforts in the research, development, production and supply of more effective vaccines and more effective, accessible and easy-to-use drugs. Now we see some light in drug research and development.
Fifth, do a good job in the corresponding material reserves and guarantees, including those for epidemic prevention and control, as well as those for ensuring normal production and life.
The sixth is to emphasize speed and accuracy, and to prevent "one size fits all" and "layers of overweight".
"If these things are combined and confidence is strengthened, we will be able to finally defeat the epidemic."
National Health Commission: The special rectification of epidemic prevention and control is simple, across the board and overweight at different levels.
Lei Zheng Long, director of the Department of Communication and Prevention of the National Bureau of Disease Control and Prevention, introduced that in June10-June 12, judging from the situation reflected by the "Public Message Board for Implementing Nine Banns on Epidemic Prevention and Control" in official website, National Health Commission, the three items that accounted for a relatively high proportion were: people in low-risk areas should not be forced to persuade and isolate, accounting for 36.36%. It is not allowed to arbitrarily expand the travel restriction range from medium-high risk areas to other areas, accounting for 26.1%; The scope of risk personnel who take isolation control measures shall not be expanded without authorization, accounting for 17.39%.
Lei Zheng Long said that National Health Commission and the National Bureau of Disease Control and Prevention attached great importance to the complaint work, and set up a special class composed of several departments in the early stage to rectify the problems of simplification, simplification and layer-by-layer overweight in epidemic prevention and control. In accordance with the working mechanism of rectifying "layers of overweight", special classes are transferred to local offices in time every day to supervise local inspections and deal with problems reflected by the masses.
"In the next stage, we will continue to adhere to the problem orientation, pay close attention to the problems reflected by the masses, and resolutely urge the rectification in place if we find that the local authorities violate the epidemic prevention and control requirements such as the' Nine Prohibitions'. We should not only do a good job in epidemic prevention and control, but also serve the masses and solve their urgent needs in time. At the same time, actively play the role of a special class to rectify the' layer-by-layer overweight' work, quickly transfer it to the office, verify the complaints reported by the masses, strengthen follow-up supervision, strengthen the notification and exposure of typical problems, and ensure that the problem of' layer-by-layer overweight' is properly resolved in time. "
National CDC: We can't use "silence" instead of control. We should resolutely avoid schools and restaurants outside the risk area.
Lei Zheng Long said at the press conference of the joint prevention and control mechanism of the State Council that it is necessary to continuously improve the scientific and accurate level of epidemic prevention and control. All localities are required to speed up accurate flow adjustment. Epidemic prevention and control cannot be simplified, risk areas cannot be delineated on a large scale, and "silence" cannot be used instead of control. It is necessary to define the middle and high risk areas in a timely and accurate manner, take resolute and decisive control measures in time, and make dynamic adjustments according to the changes in the epidemic situation. Those who meet the conditions for unsealing should be unsealed in time to facilitate people's life and travel. For schools, restaurants and other units outside the risk area, strengthen epidemic monitoring, resolutely avoid "shutting down" and minimize the impact of the epidemic on economic and social development. At the same time, it is necessary to reduce the impact of epidemic prevention and control on the masses. In response to the epidemic, while emphasizing scientific and precise control, we should also pay attention to the temperature, fully guarantee the people's living materials supply and medical needs during the epidemic, and comprehensively coordinate the efforts of community social organizations, owners' committees, property service enterprises, volunteer service personnel and other parties to ensure protection, service and warmth. At the same time, we call on the masses to enhance their legal awareness and strictly abide by laws, regulations and policies and measures.
Lei Zheng Long said that guidance on epidemic prevention and control should also be strengthened. Guide all localities to fully implement the policies and measures of the ninth edition of the prevention and control plan, strengthen the training and guidance on the policies and measures of epidemic prevention and control in all localities, promote the strict implementation of epidemic prevention and control requirements in all localities, strengthen the epidemic prevention and control of key places and key people, especially passenger cars and trucks in the transportation industry, and do a good job in epidemic prevention and control to ensure the normal development of the industry.
National Center for Disease Control and Prevention: At present, the epidemic situation in China is severe and complicated, but it is generally controllable.
Lei Zheng Long said that recently, China is facing the dual risks of importing overseas epidemic and spreading local epidemic, and the local epidemic has picked up. The epidemic situation in Xinjiang has been repeated, but it is generally controllable. The epidemic situation in Inner Mongolia has obviously improved, and the number of cases has obviously decreased. The epidemic situation in Sichuan, Gansu and Shanxi has been gradually controlled, while the epidemic situation in Ningxia and Tibet has improved steadily, and the epidemic situation in other provinces is more frequent. At present, the epidemic situation in China is severe and complicated, showing the characteristics of multiple points, wide areas and multiple occurrences. The risk of local clustering epidemic still exists, but it is generally controllable. The National Health and Wellness Commission and the National Bureau for Disease Control and Prevention strengthened overall planning, guided all localities to implement epidemic prevention and control measures before and after the National Day, and sent working groups to strengthen the epidemic prevention and control forces in Xinjiang, Inner Mongolia, Ningxia, Yunnan, Shanxi and Tibet. All localities should tighten the responsibilities of the four parties, seek truth from facts, report and publish epidemic data in a timely and objective manner, continue to strengthen epidemic prevention and control and response, and resolutely hold the bottom line that no large-scale epidemic will occur.
Will it continue the prevention and control policies before and after the Mid-Autumn National Day?
Lei Zheng Long said that during the Mid-Autumn Festival and National Day, the mobility of people increased, and the risk of epidemic spread was high. On the basis of fully implementing the ninth edition of the prevention and control plan, the joint prevention and control mechanism of the State Council has strengthened a series of prevention and control policies and measures, such as advocating safe and orderly travel of the masses, promoting landing inspection, checking negative certificates of effective nucleic acid testing in key places and institutions, and reducing unnecessary gathering. The National Health and Wellness Commission will organize and evaluate the effect of these measures on early detection, control and prevention of large-scale rebound of epidemic situation. In the next step, on the premise of adhering to the general policy of "dynamic clearance", on the basis of evaluating the effect of measures, combined with the situation of epidemic prevention and control at home and abroad, virus variation and other factors, we will continue to improve and optimize the policy of epidemic prevention and control, and make overall plans for epidemic prevention and control and economic and social development.
Wu Zunyou: Practice has proved that the general policy of "dynamic clearing" is scientific and effective, which is in line with China's actual situation.
Wu Zunyou, chief epidemiologist of China CDC, said that "dynamic zero eradication" is the general principle of controlling acute infectious diseases in China and COVID-19. In the past three years, there have been more than 300 local epidemics caused by overseas imports in China, and these epidemics have been well controlled. Practice has proved that the general policy of "dynamic clearing" is scientific, the effect is remarkable, and it is in line with the actual situation in China, so we must now.
Wu Zunyou introduced that the spread of infectious diseases from high epidemic areas to low epidemic areas is a natural law of infectious diseases, just like water flows from high level to low level. After the epidemic situation in Wuhan was controlled, China mainly imported from abroad, which caused the spread of local epidemic situation. Therefore, China has determined the general strategy of "external defense investment, internal defense rebound". Practice has proved that this overall strategy is scientific and effective.
Wu Zunyou: COVID-19 has a wide range of sequelae, and the symptoms may last for weeks, months or even longer.
Wu Zunyou said that the sequela of COVID-19 is also called the long-term symptom of COVID-19. According to the clinical definition given by WHO in 2002110, COVID-19's sequela usually occurs within 3 months after the onset of COVID-19 infection, which can be some new symptoms after the acute infection is cured, or some symptoms of the original acute infection persist for at least 2 months, which can be repeated and cannot be explained by other diagnosis.
According to global research results, COVID-19's sequelae cover a wide range of health problems, including fatigue or fatigue, difficulty in thinking or concentration, shortness of breath or difficulty, headache, dizziness, rapid heartbeat, chest pain, cough, joint or muscle pain, depression or anxiety, fever, loss of smell or taste, and so on. These symptoms can last for weeks, months or even longer.
COVID-19's sequelae are common in severe cases, but they can also appear in minor cases. People who have been vaccinated have a lower risk of sequelae after being infected with COVID-19 than those who have not been vaccinated. Wu Zunyou said that the best way to prevent sequelae of COVID-19 is to prevent COVID-19 infection.
China CDC: BF.7 has strong communication skills.
Dong Xiaoping, chief virologist of China CDC, said that subfamily BF.7 is actually the abbreviation of BA.5.2. 1.7, which is a derivative of Omicron BA.5 mutant. Since the continuous detection of BF.7 in September, it has gradually become a common strain in many countries, and its global proportion has increased from about 3.5% in late September to about 1 1% last week. Similar to other evolutionary branches of Omicron, such as BA.2 and BA.5, subfamily BF.7 shows strong transmission ability, and whether it can become the next dominant epidemic strain in the world needs further observation. The pathogenicity of BF.7 clades has no obvious change.
Liang Wannian: The COVID-19 epidemic lasted for nearly three years, which is rare in the history of human epidemics.
Liang Wannian, head of the expert group of the National Health and Family Planning Commission's epidemic response and disposal leading group, said that all countries in the world will be affected by the epidemic on economic development, and one purpose of epidemic prevention and control is to avoid and mitigate the impact of the epidemic on economic development as much as possible.
Because the epidemic in COVID-19 has lasted for nearly three years, it is rare in the history of human diseases, especially epidemic diseases, and the prevention and control measures of the epidemic will also change and adjust accordingly, which will inevitably have a certain impact on economic development. This is why our country adheres to the general strategy of "external defense investment, internal defense rebound" and the general policy of "dynamic clearing", with special emphasis on scientific prevention and control, legal prevention and control, and precise prevention and control, with the aim of minimizing the epidemic situation and reducing the adverse impact of epidemic prevention and control measures on the economy and society. Practice has proved that China's prevention and control is scientific and effective, and its achievements in prevention and control effect and economic development are world-leading, and the relationship between epidemic prevention and control and economic development has been effectively balanced.
Liang Wannian said that human beings are facing epidemic diseases. Considering that benefits are not only economic gains and losses, but also health accounts, especially people's livelihood accounts and social accounts, we should use a dynamic perspective to settle accounts. From the perspective of public health, it is the most cost-effective to protect the interests of a wider, longer-term and larger population in the face of the epidemic.
