U.S. experts announce research results: Causes of emerging crown virus identified, not from Wuhan!

U.S. experts announce research results: Causes of emerging crown virus identified, not from Wuhan!


Since the outbreak of new crown pneumonia, the origin of the new crown virus has been a mystery. According to a CCTV report on March 30, Robert Garry, a professor at Tulane University Hospital in the United States, said in an exclusive interview with ABC that "Wuhan is by no means the source of the new crown virus." He said that the new crown virus does not come from the laboratory, but occurs in nature. This virus is not new, but has spread for several years, even decades.

It is reported that the United States "Natural Medicine" magazine published the genetic research results of several scientists at La Jolla Crips Institute and Tulane University, which proves that the new crown virus is not manufactured in the laboratory, nor is it a purposeful artificial Manipulated virus. The article believes that the new crown virus does not have a "previously used virus backbone structure", so it is not created by human laboratories. It may be a combination of a bat-hosted crown virus and a pangolin-hosted virus. The new coronavirus is 96% similar to the coronavirus in bats. 4% of the differences are caused by mutations in the gene, and the virus is more infectious.

Gary said in an interview: "The virus may mutate during transmission and then become more transmissible and pathogenic. The spike protein mutation of the new crown virus was the main cause of the pandemic. The virus had previously It has been around for many years, and may have been transmitted in a weaker version for decades. "Gary emphasized that there were some cases in Wuhan but definitely not the source of the virus, and research members have discovered earlier origins than the seafood market.

Collins, president of the National Institutes of Health, also said on March 26 that the latest genetic research proves that the new crown virus is a product of nature and is caused by mutations in the virus's genes. The level of technology possessed by humans cannot create infectivity Such a powerful virus.
Collins said that the spike protein of the new crown virus binds to human cells at a very high level, and the new crown virus can evolve by itself under the targeted selection of ACE2 until it has a strong ability to bind to human cells. This level of evolution has exceeded the computational power of all human experimental models, and only occurs with small probability in the natural environment. This means that the new coronavirus was transmitted in a weaker version for a very long time, and it was not until the gene mutation that it caused the outbreak.

According to the research report, there are two possibilities for the source of the new crown virus. One is that the new crown virus has been transmitted between humans and animals in a weaker version until one day it has acquired human-to-human transmission ability; the other may be that the virus has evolved in bats and pangolins. Spike protein mutations have been passed on to humans, or gene mutations may have occurred after transmission to humans. The article believes that it is very important to use scientific evidence to combat the spread of various rumors, so that more people can focus on how to respond to the epidemic, instead of believing in "conspiracy theory".



                                 Judging from the research results of American experts, it is possible to rule out the possibility that the new crown virus originates from human experiments, and the possibility that the new crown virus originates from the Wuhan seafood market. In fact, the emergence of any virus has its contingency and certain inevitability, and no country can guarantee that a large-scale infectious disease will not occur. Before we can find out the true source of the virus, what we can do is to stop trusting rumors and put an end to wild animal trading, and the country has established a mature and effective mechanism to respond to sudden infectious diseases.
