The virus is weak or has been circulating for several years, many countries found no cases of Chinese contact history!

American virologist: #, Robert Garry, a professor at Tulane University, made it clear in an interview with ABC News that, based on their analysis, #. "I can tell you it's not a biological weapon, no one made this virus in the lab, it's a product of nature,"
said.
Now we don't know how long the virus has survived in humans, maybe only a few months, maybe years, or even decades, and then a small mutation has occurred to allow it to spread faster.
"American Viroologist: The weaker version of the new coronavirus may have been circulating for years.
recently, Robert Garry, a professor at Tulane University in the United States, made it clear in an interview with ABC that, based on their analysis, the Wuhan seafood market is not the source of the new coronavirus.
this conclusion has quickly attracted the attention of the international community.
What Robert Garry has to say, it's a brief look back on the story: On March 17th Nature Medicine, the world's top academic journal, published a new research paper by five scientists from the United States, britain and Australia.
the main point of the paper is that the new crown virus "is not built in the laboratory, nor is it a purposeful human-controlled virus". On March 18,
, the official website of Tulane University in the United States published a video of an interview with Robert Garry, one of the authors of the paper, a virologist at the university.
in the video, Professor Gary presents their team's research on the origin of the new crown virus. "I can tell you it's not a biological weapon, no one made this virus in the lab, it's a product of nature,"
said.
Now we don't know how long the virus has survived in humans, maybe only a few months, maybe years, or even decades, and then a small mutation has occurred to allow it to spread faster.
" video of robert-Garry's interview with virologist Robert Garry ,the video was released on the official website of Tulane University, March 27, and ABC reported an interview with Robert Garry.
in this interview, Gary made a key message: Although some people think the virus originated in a seafood market in Wuhan, he thinks it is wrong: "Our analysis, and some scientists' analysis, all point to an earlier origin than a seafood market in Wuhan," gary said.
"," according to the context of the contact context of the "but it's the 'the origin of the virus), where the het-it refers to the Wuhan Seafood Market (i.e. the South China Seafood Market).
more and more scientific research has been found in fact, more and more scientists through research, more and more discoveries.
for example, on January 24, the online edition of The Lancet published a research paper by seven clinicians from Jinyintan Hospital in Wuhan, which focused on 41 cases of new coronary pneumonia, and found that 13 of them had no contact with the South China seafood market. On January 26,
, Science published an article entitled "Wuhan South China Seafood Market May Not Be the Birthplace of the New Coronavirus", quoting Daniel Lucie, an infectious disease expert at Georgetown University in the United States, as saying: "There is no connection between 13 individuals and this market, not a small number."
", he believes that if this is the case, the new coronavirus may have originated elsewhere. Zhong Nanshan, an authoritative respiratory specialist in
China, also pointed out recently that the outbreak first occurred in China, but not necessarily from China.
, the Canadian think-tank Global Research published an article on its website signed by Larry Romanov, citing an analysis by virologists in Taiwan, China, of the sources of the virus in the heavily affected Iran and Italy, noting that the two countries have now released locally popular genomes and found that they differ from those in China.
article also points out that because of the heavy media attention in China, many people think the new coronavirus is spreading from China to other countries, but now it seems to have been proved wrong. On March 26,
, cell, a leading international academic journal, published a commentary by Zhang Yongzhen, an adjunct professor at the Public Health Clinical Centre in Shanghai (affiliated with Fudan University), and Edward Holmes, professor of the School of Life and Environmental Sciences and the School of Medical Sciences at the University of Sydney, Australia.
their team was the first to disclose the full gene sequence of the new coronavirus to the world.
comment that by December 2019, the new crown virus may have undergone some key mutations during the "hidden spread" phase of the population.
this means that the new coronavirus may appear in the population sooner than thought, or even not the earliest in Wuhan.
many countries found no chinese contact history cases, more and more countries found no Chinese contact history cases.
, for example, the discovery of a patient in California with no history of travel to the worst-hit areas of the outbreak, no known cases of new crown pneumonia, the first two confirmed cases in Iran and no history of travel in China, and a Japanese man who returned from a trip to Hawaii to Japan and did not visit China in the short term.
, although the first known case of new crown pneumonia in the UK, Patient No. 1, was discovered on January 31st, the latest study found that there were already new cases of coronary pneumonia in the UK in mid-January, from a family in East Sussex (currently being examined), the BBC and others reported.
a survey of members of the family's early activities found that they had no history of contact with Chinese in the month before the onset of the disease, but had a history of contact with Americans.
so, people ask, where does the virus come from? In a word: believe in science! Listen to professional and scientific advice! No matter where the virus originates, do not point it to any race, color, territory, which is an international consensus, but also the conscience of mankind! As Professor Gary pointed out in an interview, mutations in surface proteins may have been the trigger for the pandemic, but a weaker version of the virus could have spread in people for years, if not decades, before it accumulated.
