The fifth wave of the epidemic in Hong Kong is getting worse, and Liang Wannian, head of the expert group of the National Health and Health Commission's leading group for the response to the new crown epidemic, pointed out in an exclusive interview with Phoenix Satellite TV recently that at present, the pathogenicity and spread of Omicron are still not fully clear, and at this stage, we must not take it lightly, and we must adhere to the prevention and control policy of "dynamic clearance". He stressed that "dynamic zeroing" is applicable to Hong Kong, and the basic principle of "dynamic zeroing" is "rapid discovery, rapid disposal, precise control and effective treatment".
Leung Man Nian proposed "five precisions" for Hong Kong's epidemic prevention work, including accurate epidemiological investigation, accurate delineation of close contacts, accurate delineation of risky areas, accurate medical treatment, and accurate implementation of community prevention and control. He believes that it is imperative to expand the scope of nucleic acid testing and find the source of infection earlier and faster.
Leung Said that Hong Kong has a large population density, frequent international exchanges, and a greater risk of various infections, including imports, and it can be said that the risk of the spread of the epidemic in Hong Kong is higher than that of ordinary cities, "for Hong Kong, it is indeed facing great challenges." He bluntly said that how Hong Kong can achieve "dynamic zero clearance" and well balance the relationship between social and economic development, production and life and epidemic prevention and control is not only a scientific proposition" but also a "proposition for people's livelihood".
"Five precise" responses to the current epidemic
In this regard, Liang Wannian proposed "five precisions" to deal with the current epidemic. Leung Believe believes that Hong Kong has a high level of informatization and urban management, and has the ability to accurately conduct epidemiological investigations and clarify the ins and outs of patient infections, such as the source of infection, the transmission path, the patient's contact population and the scope of activity space. He believes that Hong Kong can find out the close contacts through the means of big data informatization, and accurately control these close contacts to avoid further continuous transmission.
How to curb the current momentum of the spread of the epidemic in Hong Kong? Liang Wannian believes that the top priority is to expand the scope of nucleic acid testing and find out the source of infection as soon as possible. Through the means of big data, in addition to effectively tracking close contacts, it is also necessary to establish networked management through strict community prevention and control. He said that prevention and control at the community level is very critical, and to try our best to truly implement the responsibility to every street, even every gatehouse, "the sense of responsibility is very important."
The "coexistence with the virus" argument is unscientific
As for the so-called "coexistence with the virus" argument, Liang Wannian believes that the so-called "lying flat" style of ignoring the virus is still too early, "at present, this judgment cannot be scientifically concluded." He said that if more specific and effective drugs appear in the future, when humans defeat this virus, the virus will be less harmful to humans, and humans can coexist with it.
"We still have to build up confidence in the fight against the epidemic." Leung Wannian is convinced that under the leadership of the Hong Kong SAR government, Hong Kong citizens will be able to effectively and quickly defeat the fifth wave of the epidemic, and mainland residents are also looking forward to resuming normal personnel and traffic exchanges with Hong Kong at an early date. ”
From SARS to the new crown Liang Wannian has experienced hundreds of battles
Liang Wannian has extensive experience in responding to the epidemic. In 2003, he was transferred to the Beijing Municipal Health Bureau as deputy director, and after more than a month, the SARS epidemic in Beijing went from "at its peak" to "basically under control".
At the time of the outbreak of the new crown, Liang Wannian served as the head of the expert group on the response and handling of the new crown pneumonia epidemic of the National Health Commission. In September 2020, Liang Wannian was commended as an advanced individual in the national fight against the new crown pneumonia epidemic. In September last year, Leung Wan-nien and margaret Chan, former DIRECTOR-GENERAL of who was who was found to be the executive vice president and dean of Tsinghua Vanke School of Public Health and Wellness, respectively.
Liang Wannian holds a doctorate degree in epidemiology from Peking Union Medical College of China, has published more than 100 papers in important academic journals at home and abroad, and edited or edited more than 40 textbooks or monographs.
The virus is constantly mutating and cannot be taken lightly
Liang Wannian, head of the expert group of the National Health and Health Commission's Leading Group for COVID-19 Response and Handling, pointed out that "dynamic zeroing" is not the same as pursuing zero infection, the key lies in rapid discovery and rapid disposal. He stressed that this is a choice for China's experience in fighting the epidemic for more than two years, "I personally believe that it is the best choice of a policy and strategy."
Liang Wannian pointed out that although Omicron's severe illness rate and mortality rate are lower than Delta's, it is still high for ordinary influenza, in addition, the epidemic is still in the global pandemic period, and the virus is constantly mutating, so it is not allowed to take it lightly and still adhere to the epidemic prevention policy of "dynamic clearance".
How to evaluate the effect of "dynamic zeroing"? Liang Wannian said that since the beginning of April 2020, dozens of outbreaks have occurred in Chinese mainland, and the government has taken a series of measures to effectively contain the epidemic around the longest incubation period without continuous transmission. "It ('dynamic zero clearance') is effective and in line with China's reality, which is also a choice for China's anti-epidemic experience in the past two years, and I personally think it is the best choice of policies and strategies."
High vaccination rate in the mainland, no "immunization depression"
In the mainland, where vaccination rates have exceeded 80 percent and local infections are generally low, some argue that China will not be able to build an immune barrier and will become a global "immune depression." In this regard, Liang Wannian pointed out that China's high vaccination rate has a high active immunity capacity, and the vaccine is still effective for the prevention of severe illness and death, so the so-called "immune depression" and the assumption of no immunization are not established.
