The Center for Disease Control and Prevention of China has made public the data of coronavirus genome detected in the wholesale market of Beijing. The infection samples were found to be older than the strains found in Europe.
China Economic Net reported citing Beijing Daily that the coronavirus genome found during the market outbreak (NMDC60013902-01,NMDC60013903-02) and the genome found in environmental samples (NMDC60013903-03) have been published.
The data have been submitted to the World Health Organization (WHO) and the Global Influenza Data Exchange Initiative (GISAID) for genome studies by the international community.
The difference between the coronavirus genome from the market and those strains that have spread in Europe, said Chinese epidemiologist Liu Jun. According to him, Beijing COVID-19 came from Europe and older than European strains.
“In the usual situation, the one with the most mutations is a newer virus. And the one who has few is, on the contrary, an earlier, primary virus. The time of its circulation refers to the earlier, respectively, its age is higher”,
The expert suggests that the infection could have arrived in Beijing with a shipment of frozen food, and because of the cold environment coronavirus could not mutate.
The infection was discovered at Beijing’s largest wholesale market, Xinfadi, on June 12. Coronavirus was confirmed by several owners of outlets and was also detected on their equipment. The authorities concluded that the source was infected salmon shipped from the Jingsheng seafood market.
The next day, a martial law regime was introduced in the Fengtai area, where the market is located, and later it was decided to suspend passenger and vehicular traffic from Beijing to other areas.
Yang Zhangqiu, a professor at the Institute of Virology, Wuhan University Medical Department, believes that Beijing’s coronavirus may be more dangerous than Wuhan. Chinese State Council Vice Premier Sun Chunlan warned of the high risk of COVID-19 spreading in Beijing and called for “careful tracing of sources” of the infection to contain the infection.
