Liang Wannian: We must adhere to the "dynamic clearance", and the vicious circle after lying flat is a disaster

Since March, the number of local COVID-19 infections reported on the mainland has exceeded 500,000, and the local epidemic points caused by the Omiljung mutation have occurred in many ways.

In fact, Liang Wannian has always stressed that the costs and benefits of adhering to "dynamic zeroing" should be calculated as a big account, an overall account, and a dynamic account. Now the cost of "dynamic clearance", including new crown vaccines, nucleic acid testing, cabin construction, human resources and other inputs, is like buying an insurance to deal with risks. In the face of the risks posed by Omi kerong, this insurance on the mainland has benefited 1.4 billion Chinese, controlled the spread of the epidemic, and in fact bought insurance for 1.4 billion people, which is worth the investment.

"Treating fast with fast" is a style of play that must be adhered to in defeating Ami kerong

Liang Wannian said that "dynamic zero clearance" is a general policy, under which many tools, measures and strategies are not static, but are constantly optimized and adjusted.

Liang Wannian first explained the current scientific connotation of "dynamic zero clearance". He believes that the core connotation of "dynamic zero clearance" is to quickly detect the epidemic situation and quickly take a series of measures to block the continuous community transmission of the epidemic. The most critical thing in "dynamic zeroing" is to effectively identify and manage the source of infection, effectively cut off the transmission route, protect the susceptible population, prevent the epidemic from rebounding on a large scale, and protect the health and life safety of the people to the greatest extent.

Liang Wannian explained that "clearing zero" has three meanings: one is the elimination of the virus; the second is the control of the disease; and the third is the control of the epidemic. With the current technology, the new crown virus cannot be eliminated, and it is difficult to control 100% of the disease. Therefore, the most critical clearance at this stage is to clear the epidemic situation.

"The essence of dynamic zeroing, one is fast, and the other is precision." Liang Wannian said that to be fast, it is necessary to maintain a high degree of vigilance, that is, the surveillance capacity of the public health system should be strengthened, the monitoring of some symptoms should be strengthened, the monitoring of the source of the disease should be strengthened, and once it is found, it will be quickly contained to control the epidemic situation to the minimum extent.

Liang Wannian believes that "curing fast with fast" is a very important experience in defeating the Aomi Kerong mutant strain, and it is also a style of play that must be adhered to now.

Another essence of "dynamic zero clearance" is precision, in addition to the accurate epidemiological investigation and other contents that have been emphasized before, Liang Wannian believes that it is more important to accurately balance the relationship between epidemic prevention and control and the normal life of ordinary people, and accurately balance the relationship between epidemic prevention and control measures and social and economic development.

"Epidemic prevention and control and economic development are not opposites, they complement each other." Liang Wannian said that the ultimate purpose of epidemic prevention and control, in addition to ensuring people's life safety and physical health, is also to promote economic development, so they cannot be opposed.

Make the prevention and control measures more humane and more warm

In areas with serious epidemics, grabbing vegetables has become a daily necessity for residents, and the lack of living materials has caused various inconveniences to residents' lives, as well as medical problems in epidemic areas.

In the process of epidemic prevention and control, how to ensure that policy measures are implemented at the same time more humane and more warm, needs to be further strengthened.

"These problems must be rectified and reformed." Liang Wannian said that for example, normal medical and health needs cannot be ignored because of the fight against the new crown pneumonia epidemic, and a mechanism must be established to ensure that the fight against the epidemic and the demand for normal medical services are not mistaken.

Liang Wannian believes that finding problems and solving problems is itself the fight against the epidemic, and it is also the final victory that is approaching the fight against the epidemic step by step.

Liang Wannian said that in response to these problems, it is suggested that all localities must be prepared from four aspects in the next step of epidemic prevention and control:

First, emergency management mechanisms. Judging from the anti-epidemic practice in various places, the epidemic command and decision-making system and the emergency management system must be linked.

Second, the supply system. When cities implement the necessary sealing and control management, how to ensure urban supply requires adequate preparation.

Third, the normal anti-epidemic material reserves, masks, ventilators, protective clothing and so on.

Fourth, the preparation of tools and means for the epidemic, nucleic acid, square cabin, isolation point, transfer vehicle, medical personnel, etc.

"These four aspects must be fully prepared, and now they are being done everywhere." Liang Wannian said that these measures would rather be prepared than not used, and cannot be used and are not prepared.

The vicious circle created by lying flat will be a disaster

The rapid spread of Omikejon, the proportion of mildly ill and asymptomatic infected people is high, is this a reason for us to relax prevention and control or even "lie flat"? And has the epidemic prevention measures implemented by the mainland at present been drastically moved?

"The prevention and control measures against Omicron are not a big deal." Liang Wannian said that both in terms of transmission, pathogenicity, and case fatality rate are far more than the flu.

Citing real-world data from Hong Kong as an example, the average case fatality rate of the Omiljung strain in the Hong Kong population is about 0.75%, which is seven to eight times that of influenza. From the perspective of the elderly population, especially the elderly over 80 years old, its case fatality rate will be nearly a hundred times that of the common flu.

Another key factor is the COVID-19 vaccination rate for the elderly on the mainland. According to the data released by the National Health Commission, as of April 18, the number of people over 60 years old in the mainland was vaccinated, covering 225.521 million people, completing the whole process of vaccination 213.938 million, the number of coverage and the number of people vaccinated throughout the whole process accounted for 85.41% and 81.03% of the elderly population, respectively, and the enhanced immunization has completed 154.874 million people.

"The number of elderly people in the mainland is huge, and the current vaccination rate of the elderly population is relatively not high enough." Liang Wannian said that once the epidemic control is relaxed, its outcome can be seen very clearly, it must be widely spread by the virus, and the number of severe illness and death of the elderly population is huge. It was a huge disaster for a country. The emergence of a large number of severe diseases, in turn, runs the medical system, and as medical workers are infected, they will inevitably cause the needs of normal medical services to be not effectively met, which will form a vicious circle.

"Once this vicious circle is formed, it will be a disaster." Liang Wannian stressed.

For the question of when everyone is concerned about when it can be released, Liang Wannian said that several conditions must be met:

From the national point of view, first of all, to ensure that susceptible people have a relatively good immunity, the existing means is to rely on vaccination, to establish a better protection. Vaccines have proven to be particularly effective in preventing severe illness and death.

The second point is that the understanding of this virus mutation needs to be further deepened. The Omikejung mutant is certainly not the last mutant, which is a consensus of the international scientific community. If Aumechjong never changes again, this is good news for mankind; but one day it becomes worse, more contagious and more pathogenic, and we still have to take stricter measures.

The third point is the preparatory measures. Treatment beds for the infection of Omikejong, including the preparation of human and material resources. Under the situation of epidemic prevention and control, effective preparation of living materials, as well as the establishment of relevant mechanisms such as transportation, distribution, and community management.
