    • Analysis of genomic data from 93 samples of the novel coronavirus suggests it was imported from elsewhere
    • The busy market then boosted its circulation and spread it to the whole city, research shows

    The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was instead imported from elsewhere, said researchers from Xishuangbanna Tropical Botanical Garden under the Chinese Academy of Sciences and the Chinese Institute for Brain Research.

    The team, led by Dr Yu Wenbin, sequenced the genomic data of 93 SARS-CoV-2 samples provided by 12 countries in a bid to track down the source of the infection and understand how it spreads.

    According to the study, which was published on the institute’s website on Thursday, analysis suggested 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,” it said.Earlier reports by Chinese health authorities and the World Health Organisation said 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 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was instead imported from elsewhere, said researchers from Xishuangbanna Tropical Botanical Garden under the Chinese Academy of Sciences and the Chinese Institute for Brain Research.

    The team, led by Dr Yu Wenbin, sequenced the genomic data of 93 SARS-CoV-2 samples provided by 12 countries in a bid to track down the source of the infection and understand how it spreads.

    What they found was that while the virus 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.

    According to the study, which was published on the institute’s website on Thursday, analysis suggested 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,” it said.Earlier reports by Chinese health authorities and the World Health Organisation said 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.US-CHINA TRADE WAR NEWSLETTERGet updates direct to your inboxSUBSCRIBEBy registering, you agree to our T&C and Privacy Policy

    The research went on to say that based on the genome data it was possible that the virus began spreading from person to person in early December or even as early as late November.

    “The study concerning whether Huanan 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 research team said.
