It has nothing to do with China! The new coronavirus spread in Italy last September, new research suggests

As for the source of the new coronavirus, New York Governor Andrew Cuomo said at a daily press briefing that there was evidence that the new U.S. crown had been introduced from Europe, and that millions of Europeans had poured into the U.S. after Trump ordered restrictions on entry to China and Asia.
New Coronary outbreaks in New York and Long Island began earlier than previously thought, with many people infected with strains of the virus from Europe, ScienceDaily reported on October 26.
new analysis also shows that most transmissions take place within the community, not from people who have traveled.
the study was published online October 22 in the journal Genomics Research.
also showed that the new York area's virus gene sequences were more consistent with strains in Europe and other U.S. states than with those in China.
, some people in the early days had more than 50 human-to-human infection chains.
in a new study on Nov. 11, researchers from the National Cancer Institute of Italy, the University of Siena and the University of Milan found that the new coronavirus SARS-CoV-2 (formerly known as 2019-nCoV) has been circulating in Italy since September 2019, three months before it was first reported in China.
results were published online November 11, 2020 in the journal Tumori Journal under the title "Unexpected detection of SARS-CoV-2 antibodies in the prepandemic period in Italy".
new study adds to the possibility that the coronavirus originated outside China and spread abroad earlier than is widely believed.
first COVID-19 patient recorded by Italian authorities was found on February 21 this year in a small town near Milan, north of Lombardo.
, however, in the new study, researchers found that 11.6 percent of the 959 healthy volunteers who participated in lung cancer screening trials between September 2019 and March 2020 had developed new coronavirus antibodies by February.
the results were obtained by conducting specific SARS-CoV-2 antibody tests on blood samples from the volunteers.
for a total of 24 weeks from September 2019 to February 2020, IgM (red) and IgG (blue) positive cases against the SARS-CoV-2 prickly protein (S protein) binding domain (RBD) accounted for the total number of screening participants (green), pictured from Tumori Journal, 2020, doi:10.1177/0300891620974755.
These findings suggest that SARS-CoV-2 circulated in Italy earlier than the first official confirmed case of COVID-19 in lombarda and even earlier than the first official reports issued by the Chinese authorities, providing new clues to the occurrence and spread of the COVID-19 pandemic. Giovanni Apolone of Italy's National Cancer Institute, co-lead author of the
paper, told Reuters that the study showed four cases dating back to the first week of October, showing positive levels of SARS-CoV-2 and antibodies, meaning they had been infected since September last year.
asymptomatic people not only test positive for serology, but also produce antibodies that kill the SARS-CoV-2 virus," Apolone said.
," he added, "this means that the new coronavirus can circulate in the population for a long time, and the fatality rate is so low that people think it's disappearing, no, it's proliferating."
" Italian researchers told Reuters back in March that they had reported a higher-than-usual number of cases of severe pneumonia and influenza in lombardo in the last quarter of 2019, suggesting that the new coronavirus may have spread earlier than previously thought.
