Influenza is a seasonal attack disease, and January is the high season for influenza, so it is important to differentiate novel coronavirus pneumonia from influenza. The main manifestation of influenza is fever, upper respiratory manifestation such as runny nose, sneezing, sore throat is relatively rare, most of them are moderate and high fever, fever above 38℃, other respiratory manifestations are relatively rare, there can be systemic symptoms such as malaise, etc. Generally the symptoms of respiratory distress of influenza are relatively rare, unless combined with more serious influenza pneumonia, there will be respiratory distress. The main manifestations of New Coronary Pneumonia are fever, dry cough and dyspnea. 60-70% of patients have cough, although the cough is not very heavy, but 30% of patients can have dyspnea. More than 80% of patients with new coronavirus pneumonia can have fever. In terms of laboratory tests, new coronavirus pneumonia with influenza has normal or low white blood cells, and lymphocytes can be normal or low. Most patients with new coronavirus pneumonia have imaging changes, taking CT or films to find inflammation in the lungs. Confirmation of the diagnosis depends on pathogenic microbiological tests, identified by nucleic acid or monitors. In contrast, influenza can be diagnosed by doing influenza antigen or nucleic acid testing. Content source: Dr. Yurai
