New York's new crown virus originated in northern Italy, Europe, and most of the virus comes from European travelers.

The New York outbreak originated in Europe? U.S. experts: The latest genetic research shows that the new coronavirus began spreading in the New York area as early as mid-February, just weeks before the first confirmed case, mainly from Europe, not from Asia, the New York Times reported Wednesday.
two new genetic studies: New York-area neo-coronavirus escants from Europe, and several u.S. researchers are looking for clues about the origin of the new coronavirus through viral genetic material obtained from thousands of patients, hoping to reveal the trajectory of the outbreak and help anti-epidemic policy makers make more informed interventions in the future.
, April 8 local time, the New York Times reported that a study by Harm van Bakr, a geneticist at the Icahn School of Medicine at Mount Sinai in New York, showed that the virus had been circulating in the New York area as early as mid-February, weeks before the first confirmed case, bringing it to New York mainly by European sending, rather than asian.
currently awaiting peer review of the study.
another study from New York University, which also showed that the new crown virus in the New York area is mainly from Europe and was widely spread in the community in February.
study lead adriana Heguy, a geneticist at New York University's Grossman School of Medicine, said most of the strains isolated from patients in the New York area came from Europe.
recently, on a CNN program, the program interviewed Anthony Fauci, a top Infectious Disease specialist in the United States and director of the National Institute sediton of allergies and infectious diseases at the National Institutes of Health. "Based on travel and flight records, New York's new crown virus originated in Italy and is in northern Italy,"
said.
I'm not surprised.
but unfortunately, the virus has quietly spread in New York before the people of New York find out.
" in addition, the day's program was connected to Viviana Simon, a professor of microbiology and infectious diseases at Mount Sinai Icahn School of Medicine, who said bluntly in a wire link, "The results were expected, but the scope of the european input cases was unexpected."
" Simon also said that comparing the results of the genome analysis of the new coronavirus identified in New York with data from the global database on gene sequencing of new coronaviruses showed that many of the viruses detected in New York were similar to those in Europe. Where does
New York's new crown virus come from? U.S. media: The latest research shows that mainly from Europe rather than Asia, the New York Times local time 8 reported that the latest genetic research shows that the new coronavirus began to spread in the New York area as early as mid-February, the first confirmed case in the weeks before the main travel from Europe brought the virus, rather than from Asia.
"Most of the virus es- and apparently from European travelers," said Harm van Bakr, a geneticist at the Icahn School of Medicine at Mount Sinai School of Medicine in New York, who co-authored a study and is awaiting peer review.
Despite studying different case groups, an independent team at NYU Grossman School of Medicine came to a strikingly similar conclusion, with the same virus esacquired in patients in the New York area as in Europe.
Dr Gonzalez-Reiche and her team found that the virus esacquired from patients in the New York area was the same as the one found in Europe. researchers at NYU Langone Medical Center at
said they analyzed samples from 75 patients diagnosed with new coronary pneumonia at New York Regional Hospital last month, about two-thirds of them from Europe.
reported that the virus appeared to have been imported into New York from several European countries, including the UK, France, Austria and the Netherlands, and adriana Heguy, a geneticist at the Center for Genomics At the medical center, said the virus appeared to have been imported into New York from several European countries, including the UK, France, Austria and the Netherlands.
Extended Reading: About 635,000 confirmed cases in the United States have died and about 28,000 have been detected by the Global New Coronary Pneumonia Data Real-Time Statistical System released by Johns Hopkins University in the United States, and as of 6 p.m. EST on April 15, 634,975 cases of new coronary pneumonia and 27,940 deaths have been detected.
in the past 24 hours, the United States has confirmed 31,986 new cases, 2,365 new deaths.
in New York State, where the outbreak is most severe, 214,452 cases have been confirmed and 11,617 deaths have been confirmed.
New York Governor Andrew Cuomo said Friday he will sign an executive order requiring all people in the state to wear masks in public places where they can't keep their social distance, and to impose civil penalties on those who violate the rules.
New York state residents have a three-day notice period before enforcing the order.
Cuomo also said that 752 people died of the new crown virus in New York State on the 14th, a slight drop from the previous day, further evidence that the state's outbreak has reached a reprieve.
Cambridge University's new coronavirus variant report mainly no evidence that the new coronavirus originated in Wuhan on April 8, the internationally renowned academic journal "Phylogenetic network analysis analysis of SARS-CoV-2 genomes."
the paper was co-authored by a team of researchers from Germany and the UK, led by Dr Peter Forster of the University of Cambridge.
, CGTN interviewed Dr. Peter Forster via video link to answer questions about the research.
Foster said the study was aimed at identifying "primitive virus types."
because there are so many rapid mutations, traditional methods make it difficult to track the COVID-19 family tree clearly, and the researchers used a "mathematical network algorithm" technique.
previously, the technique was mainly used to analyze DNA to map the activity of prehistoric human populations.
this is the first time it has been used to track the route of infection of the coronavirus.
researchers analyzed data from 160 new coronavirus (SARS-Cov-2) genomes collected from around the world between December 24, 2019 and March 4, 2020, and found three major SARS-Cov-2 variants, which were named A, B and C according to amino acid changes.
the a-type virus is the closest to the coronavirus found in bats and pangolins, and is the original virus type, type B is derived from Type A and Type C is derived from type B. in addition,
, the three variants vary greatly across the global distribution.
A and C are found in Europeans and Americans, and Type B is the most common type in East Asia.
Foster said one of the first genomes to be discovered when the outbreak in Wuhan became apparent was the type B virus.
researchers mistakenly thought that type B was the original virus, but this is not the case, type A is the original virus, at that time in Wuhan is only a few, but after the outbreak of the Main virus class in Wuhan, and further mutated to type C.
study found that nearly half of the samples infected with type A came from outside East Asia, mainly in the United States and Australia, and two-thirds of the U.S. samples were infected with type A.
, although type A first appeared in Wuhan, but Wuhan has very few cases of infection.
some Americans who have lived in Wuhan have been found to carry the Genome of the Type A virus.
and Type B is mainly distributed in China and East Asia, and the B-type genome outside Asia has mutated.
Type C is the main type of virus transmitted in Europe and has been found in the United States and Brazil, but has not been found in Chinese mainland infection samples and are found in Hong Kong, China, Taiwan, Singapore and South Korea.
Foster said studies showed that the first case of infection with neo-coronary pneumonia may have been transmitted from bats to humans, between September 13 and December 7, 2019.
the virus genome sampled from Wuhan on December 24, 2019 does not tell us exactly what the disease originated from.
