There are voices saying that the 'new coronavirus artificial theory' should be formally discussed.
It has been a year and a half since the pandemic of the new coronavirus infection (COVID-19) occurred, but where did the new coronavirus (SARS-CoV-2), the virus that causes COVID-19, come from? I don't know exactly. So far, the prevailing theory is that the virus infects humans from bats, but some scientists say, 'Is SARS-CoV-2 artificially made in the laboratory?' There are voices saying that the theory must be formally discussed.
Covid-19: why the lab leak theory must be formally investigated

The Wall Street Journal reported on May 23, 2021 that a previously undisclosed report was released by the U.S. Department of State, with three researchers at the Wuhan Institute of Virus Research in Wuhan, China. , It was found that he was complaining of 'the same symptoms as COVID-19' and 'general seasonal disease' in November 2019. This happened before the spread of the infection was reported, and some people said, 'Isn't the source of the virus still in the laboratory?'
'In the absence of conclusive evidence, we must have a serious discussion without conspiracy theories,' said Virginia Broker of the Center National de la Recherche Scientifique and Etienne de Chlorie of the University of Aix-Marseille. He introduces cases that claim two theories of the new coronavirus, the ' zoonoses theory' and the 'artificial theory'.
◆ Zoonotic disease theory
The first issue raised regarding the origin of SARS-CoV-2 was a treatise published in the medical journal The Lancet on February 19, 2020. Signed by 27 scientists from Colorado State University and others, the treatise focuses on the efforts of Chinese scientists to identify the cause of the pandemic and share the results, and strongly condemns the 'new coronavirus artificial theory.' It is the content to do. However, while the authors commented on the SARS-CoV-2 genome sequence, they did not elaborate on the scientific debate supporting the zoonotic theory.
In a paper published in the scientific journal Nature Medicine in March 2020, five scientists from the University of Edinburgh and others said, 'Coronavirus outbreaks follow a normal mechanism.' 'The genome sequence of SARS-CoV-2 is It is far from other known coronaviruses, and it is not possible to create a new virus from an existing virus. ”“ There is no evidence of genetic manipulation in the SARS-CoV-2 genome sequence. ” However, there is a method that allows scientists to perform homologous recombination without leaving a trace, so the theory that 'there is no trace of genetic manipulation' remains questionable. The content of this treatise is summarized in the following articles.

In addition, in a survey conducted to prove the zoonotic disease theory, all the samples detected in 30 species and 80,000 animals in various regions of China were negative. However, Brokers advise that this does not deny the zoonotic theory.
◆ Artificial theory
Broker said that the Bulletin of the Atomic Scientists and the COVID-19 research organization DRASTIC were probably the first to raise the question that SARS-CoV-2 was made in the laboratory. Have stated. In addition, the first scientific paper on artificial theory, by the research team, such as PSL research universities of France, including Mr. Dokurori in November 2020 submitted in addition to being, scientists 18 people such as Fred Hutchinson Cancer Research Center The signed paper was published in Science , a research and academic journal, on May 14, 2021.
Claims by these organizations include 'The Wuhan Institute of Veterans Affairs handles viruses close to SARS-CoV-2 and was conducting animal experiments', and in addition to direct genetic manipulation, animal capture Brokers say that it is possible that the virus was accidentally infected when dealing with a virus that evolved inside or through experiments.
There is no clear evidence of any of these theories, and the current situation is that the speculation has stopped. In a February 2021 survey, a research team from the World Health Organization (WHO), which was conducting a joint survey with China, concluded that 'it is extremely unlikely that the new corona virus was leaked from the Wuhan laboratory.' but, the next month of the study, Tedorosu-Adanomu Secretary-General of WHO is 'not been demonstrated all of the hypothesis, further research is needed' and says .
'Whatever the origin, the collection and experimentation of potentially pandemic viruses, the increase in laboratories that require a high degree of security, especially near cities, should be questioned. The facility requires a rigorous safety system similar to that used for nuclear energy research and new security measures should be introduced internationally. What flaws have led to the spread of SARS-CoV-2? In order to know what it is, we need to know its exact origin. '
