US scientists: Wuhan is by no means the Source of the new Coronavirus
A recent study by the US scientists on the new crown virus
showed that "Wuhan is by no means the source of the virus." The study
said that the virus that caused the global pandemic did not come from the
laboratory, but was produced naturally. The weaker version of the virus has
been circulating in the population for years, even decades.
"Norovirus is not constructed in the laboratory"
According to an analysis of evidence published in the
scientific journal Natural Medicine, the New Coronavirus "is not
constructed in the laboratory, nor is it a purposeful, man-made virus."
Robert Gary, a professor at the Tulane University School of
Medicine, is one of the authors of the paper. He believes that conspiracy
theories are now popular on the Internet, and it is necessary to use the entire
team to explore the origin of this new coronavirus.
The director of the National Institutes of Health, Francis
Collins, also supports the argument in this article. He said on his personal
blog that the study proves that the new crown virus originates from nature and
is highly convincing.
The weaker version of the virus has been circulating in the
population for years.
This mutation was responsible for the pandemic
The researchers found that the coronavirus does not have a
"previously used virus backbone structure", so it was not created by
humans. It may have been developed by combining a virus found in bats with
another virus carried by pangolins.
"Natural
Medicine" article: New crown virus is not constructed in the laboratory, nor is it
intentionally man-made.
The new coronavirus is 96% similar to the coronavirus found
in bats, and it is the 4% variation that explains why it is so infectious.

Gary told ABC News: "We know from studies of other
coronaviruses that viruses can acquire this mutation and then they become more
pathogenic. This is a good explanation of why this virus is so Easily spread
and led to the current pandemic. "
Wuhan is by no means the source of the new crown virus
Gary said that mutations in surface proteins may have
triggered the pandemic, but weaker versions of the virus have been circulating
in the population for years, even decades, before accumulating to the present.
At the same time, although many people believe that the virus
originated in a seafood market in Wuhan, China, Gary said that this is also a
wrong view. "Our analysis and other analyses point to an earlier origin
than there. There must be some cases in Wuhan, but by no means the source of
the virus."
