A new detailed and comparison
genomic research study by Chinese researchers involving 93 virus samples from 12 countries worldwide that have had patients infected with the
coronavirus revealed that the new
coronavirus did not originate from the Wuhan market but rather was ‘imported and the busy market had simply only boosted its circulation and spread it to the whole city.

The
research shows that the new SARS-CoV-2
coronavirus that causes the Covid-19 disease that has claimed the lives of more than 2,700 people so far did not originate at a seafood market in the central China city of Wuhan as was first thought.
Instead, the
research proves that the new severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) was instead imported from elsewhere, according to the genomic and medical scientists from Xishuangbanna TBG Institute that under the Chinese Academy of Sciences and the Chinese Institute for Brain Research.
The
research team, led by leading
genomic Professor, Dr Yu Wenbin, sequenced the
genomic data of 93 SARS-CoV-2
coronavirus samples provided by 12 countries in order to track down the source of the infection and understand how it spreads.
The researchers found was that while the
coronavirus had spread rapidly within the Huanan Seafood Wholesale Market in Wuhan, there had also been two major population expansions on December 8 and January 6
Analysis of the
research findings, which was published on the institute’s website, indicate that the
coronavirus was introduced from outside the market. The crowded market then boosted SARS-CoV-2 circulation and spread it to the whole city in early December 2019, the study indicated.
This totally contradicts earlier reports by Chinese health authorities and the World Health Organization announcing publicly that the first known patient showed symptoms on December 8, and that most of the subsequent cases had links to the seafood market, which was closed on January 1.
The study also implied that based on the
genome data, it was possible that the
coronavirus began spreading from person to person in early December or even as early as late November.
Dr Yu Wen Bin, lead researcher of thestudy, told
Thailand Medical News, “The investigative and detailed study concerning whether Wuhan market is the only birthplace of SARS-CoV-2 is of great significance for finding its source and determining the intermediate host, so as to control the epidemic and prevent it from spreading again.”
The study findings have lots of implications and also raises a lot of questions including as to how it got to Wuhan.
Meanwhile, Dr Xiang Nijuan, a researcher at the Chinese Centre for Disease Control and Prevention, said in an interview with state broadcaster CCTV that people infected with the new
coronavirus were contagi
ous two days before they showed any symptoms.
Therefore anyone who had been in close contact with someone within 48 hours of them being confirmed as infected should put themselves in isolation for 14 days, he said.
