(Fighting against New Coronary Pneumonia) WHO report: All known evidence indicates that New Coronavirus is not artificially manipulated or synthesized
China News Agency, Brussels, April 23 (Geneva): Following a WHO spokesperson refuting the conspiracy theory on the origin of the new crown virus on the 21st, the WHO again emphasized through its daily outbreak report on the 23rd that all known evidence indicates that the source of the new crown virus From natural animals, not artificially manipulated or synthesized by the laboratory.
The report of the day specified the source of the new coronavirus in the "focus" column. According to the report, after Wuhan reported human cases of new coronavirus in December 2019, the whole genome sequence of the new coronavirus was announced and shared from January 11 to 12. Since then, the complete genome sequence of the virus from early infection cases and the complete genome sequence of the virus obtained from other parts of the world have shown that the evolution of the new coronavirus can be traced back to the bat population.
The report emphasizes that many researchers have seen the genome characteristics of the new coronavirus and found no evidence to support the synthesis of the new coronavirus in the laboratory, because if the virus is synthesized in the laboratory, it will show a series of known elements in the genome sequence, but the new coronavirus does not This situation exists.
"All known evidence indicates that the virus originated from natural animals, not a man-made or synthetic virus," the report said, further explaining that it was integrated with Ebola, avian influenza, Middle East Respiratory Syndrome (MERS), severe acute respiratory tract Similar to SARS, infectious diseases caused by New Coronavirus are zoonotic diseases (infected to humans through animals).
According to the report, due to the limited close contact between humans and bats, the new coronavirus is likely to be transmitted to humans through the intermediate host, that is, the animal population that is more easily in contact with humans. Wild animals or artificially cultivated wild animals.
The report also pointed out that the whole genome sequences of the new coronaviruses released by all parties so far are very similar, indicating that the introduction channel is relatively single at the beginning of the outbreak. In order to gain a deeper understanding of the causes of the outbreak, the Chinese government is conducting a number of investigations, covering early infection cases in Wuhan and surrounding areas, environmental sampling of the local fresh farmers market, and the sources and types of wild or farmed animals sold in these markets.
According to the report, WHO will continue to cooperate with member countries, animal and human health experts and other parties to identify research gaps and priorities for the prevention and control of the new coronary pneumonia epidemic, including targeting the source of the new coronavirus to prevent the epidemic from spreading further in the population.
