Novel coronavirus pneumonia is characterized by fever, cough, and dyspnea. Initially, sneezing and runny nose may occur, and then dyspnea, respiratory distress, uncorrectable metabolic acidosis, and even bleeding and clotting dysfunction may occur a week later when pulmonary inflammation develops. Heavy inflammation of the lungs leads to heavy coughing. In addition, it should be judged according to the different periods of inflammation. If only a severe dry cough appears, the possibility of novel coronavirus pneumonia is not excluded, but it is not necessarily a new coronavirus infection. Because respiratory tract infections, including pneumonia, bronchitis or pharyngitis caused by other common bacterial infections, can present a severe dry cough, the presence of cough, itchy throat and severe dry cough should be considered based on laboratory tests, chest CT and the evolution of the patient’s condition to give a clear diagnosis.
