Refutes the "laboratory leak" conspiracy theory, multiple real hammers prove that the new crown virus comes from nature

　　On May 12, 2021, local time, Washington, DC, the capital of the United States, on the day of International Nurses Day, members of the National Nurses Federation of the United States placed hundreds of pairs of nurse shoes in front of the White House to commemorate the nurses who died in the fight against the new crown pneumonia epidemic.

　　Recently, the World Health Organization released the second-stage virus traceability plan of the new crown pneumonia epidemic. The plan puts the hypothesis of "China's violation of laboratory procedures causing virus leakage" as one of the research priorities.

At a press conference held by the State Council Information Office on July 22, Zeng Yixin, deputy director of the National Health Commission, said that this kind of formulation violates common sense and violates the laws of science. It is impossible for the Chinese government to accept such a traceability plan. .

　　Zeng Yixin pointed out that the traceability of the new coronavirus must be a scientific issue. The Chinese government has always supported scientific traceability of the virus. “However, we oppose the politicization of traceability. We believe that the second-stage virus traceability should be extended on the basis of the first-stage virus traceability. The World Health Assembly (WHA) Resolution 73.1 is used as a guide, and it is carried out after full discussion and consultation by member states. The first phase of the virus traceability has already been carried out, especially if there is a clear conclusion, it should not be repeated."

　　On July 4, the Chinese expert group put forward the Chinese proposal for the second phase of the traceability work to the World Health Organization and communicated with the WHO experts.

Zeng Yixin said: "Our considerations and core views are reflected in this draft proposal. We hope that the WHO can seriously consider the considerations and suggestions put forward by Chinese experts, and truly treat the traceability of the new crown virus as a scientific issue and get rid of political interference. Actively and steadily promote the continuous traceability in many countries and regions around the world, strengthen the cooperation and exchanges of traceability research between countries, find the most likely source of the virus as soon as possible, and do our best to prevent similar epidemics from recurring."

　　World Health Organization first stage traceability (Chinese part) results: "extremely unlikely" laboratory introduction

　　In March, the World Health Organization publicly released the World Health Organization-China Joint Research Report on the Global Traceability Research (Chinese Part) of the Novel Coronavirus.

The Chinese-foreign joint expert team participating in this traceability study conducted a scientific evaluation of the possibility of the introduction of the new coronavirus from the natural host through cold chain food, directly from the natural host, through the intermediate host, and laboratory. The conclusions are divided into five levels: extremely unlikely, impossible, possible, more likely, and very likely.

　　This report pointed out that the introduction of the new coronavirus through the laboratory is "Extremely Unlikely" (Extremely Unlikely), which is a consensus reached by a group of Chinese and foreign experts.

On March 31, Liang Wannian, the Chinese leader of the joint expert group, stated at the State Council’s joint prevention and control press conference that the direct overflow of zoonotic diseases was seen as a “probable” to “more likely” approach; it was introduced through an intermediate host, It is regarded as a way from "more likely" to "very possible", "This has a range, especially the intermediate host, from more likely to very likely, introduced through cold chain and food chain products, it is considered As a possible way".

　　Liang Wannian introduced that the introduction of "extremely impossible" in the laboratory is a conclusion drawn from two dimensions.

There are only two most likely channels for laboratory introduction: one is artificial synthesis. Scientists have a clear attitude towards this, which is impossible; the second is leakage. The most critical point of leakage is whether there is a laboratory. Chinese and foreign expert groups specially went to the Wuhan Institute of Virology for a more detailed understanding, and conducted inspections on the site with relevant researchers, including relevant management personnel. In particular, we carried out its standardized procedures, management systems, and security systems, including what Wuhan Virus was engaged in. The research project, the understanding of some projects that have been done in the past and some projects that are currently being done, finally came to the conclusion-'very unlikely'

　　Yuan Zhiming, director of the Wuhan National Biosafety Laboratory of the Chinese Academy of Sciences and researcher of the Wuhan Institute of Virology, emphasized at the press conference on July 22: 1. Before December 30, 2019, the Wuhan Institute of Virology had not contacted, preserved, or studied the new coronavirus; 2. The Wuhan Institute of Virology has never designed, manufactured, or leaked the new coronavirus; 3. So far, the employees and graduate students of the Wuhan Institute of Virology have maintained "zero infection" of the new coronavirus.

　　Yuan Zhiming added: "Some media have reported that'all three researchers from Wuhan Virus Research visited the hospital in November 2019, and their symptoms were the same as those of the new crown virus.' This is completely out of nothing. If you want to figure it out. The truth of this fact is actually very simple. You only need these media reporters to tell us the names of these three people, and the truth will be revealed. In fact, we made this proposal very early, but we have not received any response until now."

　　Yuan Zhiming pointed out that in the face of the current COVID-19 pandemic, it is impossible for any country to be alone. Only global cooperation and coordinated actions can effectively curb the spread of the virus and bring the people around the world back to prosperity and harmony. life.

The Wuhan Institute of Virology will uphold an open and transparent attitude and is willing to work with scientists to continue to contribute to the fight against the new crown pneumonia epidemic.

　　"The Lancet" published an article: There is no scientific evidence to support the leak of the new crown virus from a Chinese laboratory

　　On July 5, the international top medical journal "The Lancet" published an article "To determine how SARS-CoV-2 was transmitted to humans, the key is science, not speculation" ("Science, not speculation, is essential to determine how SARS-CoV-2 reached humans”) clearly stated that there is currently no scientific evidence to support the theory that the new coronavirus leaked from a Chinese laboratory.

This article was co-written by 24 well-known experts.

They pointed out in the article that the evidence obtained by scientific methods must be used to help deepen understanding and serve as the basis for explaining existing problems.

This process is not without errors, but it can be self-corrected because excellent scientists strive to constantly ask new questions, apply new methods, and correct their conclusions through open and transparent data sharing and continuous dialogue.

　　The article also pointed out that allegations and speculations are not helpful, because they do not help to obtain more information, nor can they help to objectively assess the path of viruses to human pathogens, which may help prevent future pandemics.

There is no mutual accusation now, and it will not promote international cooperation in any way in the future.

New viruses can appear anywhere, so maintaining transparency and cooperation between scientists everywhere provides a vital early warning system.

　　On February 19, 2020, "The Lancet" published an article "Statement in support of the scientists, public health professionals,

　　and medical professionals of China combatting COVID-19”), the above 24 scientists participated. This article pointed out that Chinese scientists, public health personnel, and medical personnel worked hard and effectively to quickly identify the pathogens behind the epidemic and took major measures to reduce Its impact and the public sharing of the results with the global health community are remarkable. "We signed this statement to support all Chinese scientists and health professionals who are saving lives and protecting global health from the challenge of the new crown pneumonia epidemic.

We are all together, standing at the forefront with our Chinese counterparts to jointly respond to this new virus threat.

"

　　After more than a year, these scientists said: "Recently, many of us have received individual enquiries asking whether we still support what we said at the beginning of last year. The answer is clear: We reiterate that we have a strong understanding of China that was fighting against the new crown pneumonia epidemic at the time. The people, as well as many health professionals around the world who have since taken personal risks and worked their best in the relentless and ongoing fight against the virus, expressed their solidarity, and our respect and gratitude is growing day by day."

　　In addition, on July 7, scientists from the United States, the United Kingdom, and Australia published a preprinted article on the European scientific data sharing platform Zenodo, stating that “there is no evidence that the new crown virus came from the Wuhan laboratory”; “there is no evidence that any early Of the cases are linked to the Wuhan Virus Research Institute”; “There is no evidence that the Wuhan Virus Research Institute owned or studied the ancestors of the new coronavirus before the pandemic.”

　　"Blind watchmaker" theory: the new coronavirus cannot be artificially synthesized

　　On July 16, 21 Chinese scientists and a British scholar working in China jointly published a titled "On the Origin of SARS-CoV-2-Blind People" in Science China Life Sciences (English version of "Science China: Life Sciences") The viewpoint article of "On the origin of SARS-CoV-2—The blind watchmaker argument", using the classic evolutionary theory—"blind watchmaker argument", strongly demonstrates why the new crown virus can only come from Naturally, it is impossible to be manufactured by man.

　　This article pointed out that compared with the SARS virus in 2003, the new coronavirus is very adaptable to humans, and the adaptive transfer from animal hosts to humans has been more extensive.

According to the "blind watchmaker" theory, this adaptive change can only happen before the current pandemic, and it needs to rely on the help of gradual selection.

In this view, the new coronavirus cannot have evolved from the animal markets in big cities, and it is even more impossible to evolve in the laboratory.

　　In 1794, a British priest, William Perry, proposed that various creatures in nature are perfectly adapted to their respective living environments, just like a delicate clock.

You can't imagine it comes from nature. Behind this, there must be a watchmaker (creator) who designed and manufactured it.

　　Richard Dawkins of the United Kingdom refuted this view. He once pointed out in "The Blind Watchmaker" that Darwin discovered a blind, unconscious, and automatic process: the existence of all living things and the seemingly purposeful Construction can be explained by a process, which is natural selection.

Natural selection has no purpose, and there is no "mind's eye".

It does not plan for the future, nor does it have foresight.

If natural selection is the watchmaker in nature, then it must be a blind watchmaker.

　　The first author and corresponding author of the paper, Professor Wu Zhongyi of the School of Life Sciences of Sun Yat-sen University and academician of Taiwan’s "Academic Research Institute", said in an interview with the media that some people promoted "artificial theory", "conspiracy theory" and "laboratory leak theory". One of the main points is to think that a virus that is so perfectly adapted to the human body like the new coronavirus can come from "blind" and aimless nature?

This is a terrible retrogression in scientific thinking-suddenly back to the thinking of a priest more than 200 years ago.

　　Wu Zhongyi said that just because the new coronavirus is the most "perfect" virus that mankind has ever witnessed, it must be a product of natural evolution.

Because even the top human scientist, when he wants to "make" a virus that is perfectly adapted to the population, he actually doesn't know what to make.

It's like even the most technical and experienced electronic product company, it is impossible to design a world's most popular mobile phone at one time-the most "perfect" product must be born out of market inspection and repeated polishing .

　　Wu Zhongyi said: "We deduced that before the outbreak of the new crown pneumonia, related viruses had experienced repeated mutual infections in wild animals and people, and gradually accumulated mutations adapted to the human body in the process. In the process of invading humans, The virus has repeatedly fought and fought until it has evolved into a state that is extremely adaptable to population transmission. The evolutionary history of human coronaviruses (OC43, 229E and NL63) related to the common cold also supports this view. These coronaviruses are spreading globally. It has been infecting and spreading between humans and wild animals for hundreds of years."

　　An Indian scholar once found that some sequences of the new coronavirus are similar to HIV, so it is speculated that the new coronavirus may be man-made and written as a paper. "However, this paper was criticized by international colleagues at the pre-print stage. Later this author took the initiative to retract the manuscript."

　　Zeng Yixin also gave an example at the press conference of the State Council Information Office on July 22 to explain that the new coronavirus cannot be synthesized by humans, because there are similar sequences in many other viruses, so it cannot be inferred from this point that the new coronavirus is artificial.

　　Zeng Yixin added that after in-depth analysis, more experts believe that the new coronavirus has no traces of artificial modification, which fundamentally denies the possibility of artificial viruses.

　　"We hope that the WHO can seriously consider the considerations and suggestions put forward by Chinese experts, truly treat the traceability of the new crown virus as a scientific issue, get rid of political interference, actively and steadily promote the continuous traceability in many countries and regions around the world, and strengthen countries. For cooperation and exchanges in tracing scientific research, we must find the most likely source of the virus as soon as possible, and try our best to prevent a similar epidemic from recurring." Zeng Yixin said, "What is the purpose of tracing? It is to figure out the source of the virus, and then be able to take effective measures. Measures to prevent similar epidemics from recurring. Therefore, we must promote this work in accordance with scientific principles and scientific rules. This is the attitude of the Chinese government."
