Liang Wannian, head of covid-19 expert group and the head of the national health and Health Committee, the new leader of the new pneumonia coping strategy, said in an interview that the general principle of dynamic zero elimination should be upholding in Hongkong's epidemic prevention work. At the same time, the goal should be implemented in stages. The resources of Chinese medicine should be collected and the goal of reducing infection, reducing severe diseases and reducing deaths should be given priority. Adhere to the general policy of dynamic clearing and achieve phased objectives first Liang Wannian said that since the outbreak of COVID-19, all countries in the world have determined their epidemic strategy and overall goals according to their social, economic, demographic, cultural, medical resources and anti epidemic concepts. In fact, the concept of anti epidemic is the most important. China has always adhered to the anti epidemic concept of putting people first and life first as the core, and has done everything possible to protect the health and life safety of the people. While adhering to the general principle of dynamic zero elimination in the process of epidemic prevention, China does not mean pursuing zero infection, because the transmission route of COVID-19 is very easy to achieve. A considerable part of its cases are asymptomatic, and its symptoms are not easily recognized and diagnosed as other infectious diseases. Like the epidemic strain of Omicron this time, with such strong transmission power, we do not fully have the means to make people zero infection. However, we will try our best to minimize infection. Once infected, how can we quickly find and identify it, and then take measures to cut off the route of transmission to protect vulnerable people from infection. "I think this is the essence of dynamic zeroing. Dynamic zeroing cannot be understood as zero infection." Liang Wannian said that speed and accuracy are the essence of dynamic zeroing. First of all, it should be fast, otherwise once sustained community communication is caused, it will pay a great cost to cut it off. Secondly, how to accurately determine the key areas? How to accurately find the source of infection? How to accurately carry out epidemiological investigation in the control area? How to accurately treat infected people? Liang Wannian said COVID-19 has posed a particularly serious threat to the health and safety of people around the world. In Hongkong, it is more obvious that measures must be taken to suppress and control it, and to do everything possible to control its harm and influence. He said that there is not enough evidence in science that COVID-19 is "large influenza". It has many unique situations, such as the rapid transmission rate, the overall mortality of the population is higher than that of influenza, especially the severe mortality of vulnerable groups such as the elderly, and so on. From Hongkong, COVID-19 is fierce and has infected a large number of people in a short time, resulting in a large number of critically ill patients. It has seriously run medical resources and endangers the lifeline of city operation. Hongkong is facing the danger of not functioning properly. "Hongkong can not choose to lie flat. If we lie flat, we will have to fight with COVID-19. We must control it, cut off its spread, and protect life as much as possible." Liang Wannian stressed. In the face of the severe situation of continuous community communication in Hong Kong, he also said that the overall policy of dynamic clearing needs to be implemented in stages and steps. The core of the current work is to determine the most priority phased objectives. "Reducing infection, severe illness and death is the most urgent and priority phased goal of Hong Kong's fight against the epidemic. After achieving the first goal, we will achieve the second and third goals." Liang Wannian said that he is still confident that Hong Kong will achieve the overall goal of dynamic zeroing, but he should have a full estimate of how long it will take. He believes that Hong Kong will be able to overcome the epidemic. Reduce severe deaths and give priority to key populations Liang said that the focus of the current anti epidemic work is to reduce the number of severe cases in Hong Kong, especially the elderly. It is suggested that the relevant departments of the SAR government establish a set of index system to evaluate who is easy to turn into severe cases and intervene in time. At the same time, we can learn from the "four centralizations" in the mainland anti epidemic, such as "centralizing patients, experts, resources and treatment". He said that severe patients are often not only respiratory problems, but also multi organ failure. He suggested that we can consider adopting an emergency and multidisciplinary centralized advantage medical model to concentrate the severe patients, multidisciplinary medical personnel, relevant medical resources and treatment system for treatment and effective prevention of death. In addition, we can also consider taking out a certain number of comprehensive and relatively high-level hospitals as designated hospitals to treat patients with severe coronary heart disease. Liang Wannian said that he was glad to see that relevant departments of the SAR government were studying and formulating relevant plans to implement diversion and layered treatment for patients. Who will determine whether the patient should enter the hospital or community isolation facilities, and what criteria will be used? How to achieve effective linkage and treatment after entering? How to establish an effective monitoring system for early identification of patients? How to guarantee medical staff and medical materials? These problems need to be properly handled and solved. He said that in terms of severe treatment, suggestions have been made to the SAR government to prepare for effective linkage between facilities, layout and all levels to form a whole treatment rather than fighting on their own. As long as the mortality of patients is reduced, it will form a great support for people's psychology, reduce fear, and boost the confidence of all sectors of society, especially medical personnel. Liang Wannian said that for specific groups, institutions and specific regions, what measures can be considered to further strengthen, optimize and improve, and highlight the key points more accurately. For example, through sewage monitoring, we can quickly judge which areas or even a building are infected, and then quickly detect the building and quickly protect vulnerable people, including vaccination, management and protection of uninfected people. Can we cut off the closed-loop management of the nursing home staff? The epidemic situation is still rising rapidly, and the whole society has formed a joint force of "war epidemic" Liang Wannian pointed out that the epidemic situation in Hong Kong is still in a period of rapid rise and belongs to an acute outbreak epidemic period. We still need to have a clear understanding of this. He said that in the four wave outbreaks, the adoption of a series of preventive and control measures by the SAR government effectively suppressed the spread of 60% to 70% of COVID-19. At present, the basic reproductive rate of the virus is around 2, meaning that after infection with 1 people, there will usually be 2 people infected. If prevention and control measures are not taken, the basic reproduction rate of the virus is 6 to 8. The measures taken now are to curb the transmission of the virus and gradually decline from about 2. If it can fall below 1, the epidemic situation will be greatly alleviated. Liang Wannian said that after the epidemic and outbreak of respiratory infectious diseases in an area, it must experience from slow growth to rapid growth, then to the peak, then the platform period, then the decline period and finally the end. When will the rapid rise of the epidemic in Hong Kong Peak? At present, a number of expert teams in the mainland and Hong Kong are conducting research. For the implementation of universal testing in Hong Kong, Liang Wannian said that this is a systematic project and we need to seize the opportunity. By what method? Who will sample? Who will deliver the specimens? How is the organization sampled? How to manage the detected positive patients and close contacts? All these need to be considered and carefully arranged. "How to take more effective and practical measures to curb the rising trend of the epidemic, reverse the situation as soon as possible and turn around? This is also one of the most important tasks in the current fight against the epidemic." Liang Wannian stressed that to really reduce infection, we need everyone, every unit, every institution and all aspects of society to work together to do what we should do in our respective posts. As ordinary people, wear masks, wash hands frequently, open windows for ventilation, avoid unnecessary travel, do a good job in personal protection, and actively exercise to enhance their physique. "I hope that these demands will become the conscious actions of every citizen of us. This is a war against the epidemic in which all Hong Kong citizens participate." Liang Wannian said that relevant departments and institutions of the SAR government also have the responsibility to educate and train their employees on epidemic prevention knowledge, so as to create an atmosphere of national epidemic resistance in the whole society.
