The difference between novel coronavirus pneumonia and the common cold and flu The difference between novel coronavirus pneumonia and common pneumonia Common pneumonia is usually due to bacterial infection, with common symptoms of coughing and sputum, or aggravation of existing respiratory symptoms with purulent or bloody sputum, with or without chest pain. It is generally not contagious and is not an infectious disease. The difference between the new coronavirus pneumonia and SARS/MERS Although the new coronavirus found here belongs to the same family of coronaviruses as SARS and MERS coronaviruses, genetic evolutionary analysis shows that they belong to different subgroups of branches, which are not SARS or MERS viruses, and their viral gene sequences are relatively different, and the current investigation shows that the interpersonal transmission capacity and pathogenicity of the virus are higher than those of SARS. The current investigation shows that this virus is weaker than SARS in terms of interpersonal transmission and pathogenicity.
