Most common colds in life are caused by infections of rhinovirus, respiratory syncytial virus, and common coronavirus, with mild symptoms, mainly including runny nose, headache, cough, sore throat, and fever. While the typical symptoms of novel coronavirus infection, mainly fever, along with malaise, dry cough, progressive dyspnea, some patients start with mild symptoms and no obvious fever, a small number of patients have more severe symptoms after infection and can quickly develop complications such as acute respiratory distress syndrome and septic shock. The common cold and the novel coronavirus infection are very similar in terms of early symptoms, according to which it is impossible to make an accurate identification, and the most accurate identification method at present is to conduct pathogenic tests.
