One expert spoke that the new coronavirus is the SARS virus, and it was verified that the new coronavirus is a SARS-associated coronavirus. This means that the new coronavirus is similar to the SARS coronavirus. Academician Zhong Nanshan said that the new coronavirus is a kind of coronavirus, it is the same class as SARS coronavirus, but not the same kind. Coronaviruses are a large group of viruses known to cause diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). Some studies have shown that the Wuhan novel coronavirus is similar to the SARS coronavirus in terms of receptor binding pathway. However, at the same time, the genome sequence of the novel coronavirus (2019-nCoV) is also very different from that of SARS-CoV and can be considered as a novel human infectious type B coronavirus. Therefore, although the novel coronavirus has structural similarities with SARS virus, it is not a SARS virus, nor is it a MERS virus.
