The evening of February 9, Hubei Province, the new coronavirus pneumonia epidemic prevention and control command held the 19th press conference, focusing on the new coronavirus pneumonia epidemic prevention and control of scientific research and research. At the meeting, Huazhong Agricultural University Professor Chen Huanchun said: analysis found that the new coronavirus belongs to the SARS coronavirus, which drew questions. In response, academician Zhong Nanshan said in a media interview: SARS coronavirus is a proper noun that refers specifically to the virus of acute respiratory syndrome, it (and the new coronavirus) is not the same thing, 2019 new coronavirus is another virus, both belong to the coronavirus. Xu Wenbo, director of the Institute of Virus of the Chinese CDC, also said: the new coronavirus is a new virus, not the SARS virus. Subsequently, Chen Huanchun said in an interview with the media after the conference that the statement was a slip of the tongue: I’m really sorry, it was a total slip of the tongue, dropping two words. It should be “the new coronavirus is a SARS-related coronavirus”. The reading of Professor Chen Huanchun at the press conference was also posted on today’s “Hubei Authoritative Release” WeChat public number, and the error can be found by comparison (see screenshot). What is SARS-associated coronavirus? The new coronavirus is a SARS-related coronavirus, and the conclusion is based on the work of Shi Zhengli’s team at the Wuhan Institute of Virology, Chinese Academy of Sciences. Shi Zhengli said in a media interview: SARS-associated coronavirus, which is the name of the virus species. The novel coronavirus uses the same receptor as the SARS coronavirus to enter the host cell and possesses 87.1 percent similarity to the SARS-associated virus found in bats and 79.5 percent similarity to the SARS virus. Similarity to a coronavirus found in a bat sample from Yunnan province was 96%. The perforated strain has 99% sequence similarity to the current infected human strain. Multiple research teams have studied the relevance of the new crown to SARS virus. on January 22, the National Center for Genome Sciences Data officially released the 2019 Novel Coronavirus Repository, which was analyzed to have 80% sequence similarity to the SARS virus genome. Similarly, a study published in The Lancet by Wenjie Tan et al. of the CDC on January 29 noted that 2019-nCov was more similar to two bat coronaviruses collected in Zhoushan, Zhejiang Province, with 88% identity compared to SARS virus. Zhu Hua Chen, associate professor at the School of Public Health of the University of Hong Kong, said in a previous media interview that by analyzing the gene sequence, it can be initially determined that its similarity to the entire genome of SARS is above and below 80%, but the similarity varies between different gene segments, ranging from 60% to 90%, respectively. “It belongs to the same group as SARS (i.e., 2bgroup) and is a novel ‘SARS-like’ or ‘SARS-like’ coronavirus.” David Robertson, a professor at the Centre for Virus Research at the University of Glasgow, UK, pointed out in an interview with China Newsweek that it could not be SARS, but the new coronavirus comes from the same virus subtype sarbecovirus as SARS, so it could be said to be a SARS-related coronavirus. After reading so many studies, a general explanation: new coronavirus and SARS coronavirus, both are coronaviruses, just different coronaviruses, two coronaviruses, there are many similarities, especially attacking the same cellular path into the human body.
