The main manifestations of novel coronavirus pneumonia are cough, fever and progressive dyspnea. Some people infected with novel coronavirus do not show typical clinical manifestations, but may have a mild cough or a short-lived fever, which is similar to the clinical course of a cold, and is easy to be overlooked. Each patient’s immune status is different, and the characteristics of the onset of disease after infection with novel coronavirus may also vary greatly. Some people will have symptoms similar to those of a mild cold, while others may present with a cough and sputum, including dyspnea. In more severe cases some people may develop acute respiratory distress syndrome, multiple organ failure including bleeding and coagulation disorders, and may even cause death.
