Rumor Identification: The virus has not been detected in bats in the past decade. Rumor Analysis: 1, the Chinese Center for Disease Control and Prevention said that the SARS outbreak in China in 2002-2003, the SARS cases have not been found in the past decade, and no human SARS coronavirus has been detected in bats. 2. The pathogen causing the “mysterious virus” in Wuhan is a new coronavirus, not SARS virus. Genetic similarity of viruses does not equate to similar pathogenic ability. Although the new coronavirus and SARS and MERS coronavirus belong to the same coronavirus, genetic evolutionary analysis shows that they belong to different subgroups of branches, and the new coronavirus is neither a SARS virus nor a MERS virus, and its viral gene sequences differ significantly. Special note: Coronaviruses are more common in nature and can be divided into many types, causing a wide range of hazards. The pathogen causing the Wuhan viral pneumonia outbreak is a new coronavirus, distinct from the SARS virus. Therefore, for infected patients should be promptly to the nearest designated hospital for isolation and treatment, both for the patient is responsible, but also for public health.
