Although the common manifestations of new coronavirus pneumonia are fever, dry cough, and fatigue, many viral infections can cause the above manifestations, such as influenza virus infection. Since winter and spring are also the most common seasons for influenza, it is important to go to the appropriate medical institution for timely diagnosis of the disease after the above symptoms occur. If there is no epidemiologic history, no visit to Wuhan or other infected areas within 14 days of the onset of fever, no contact with similar patients, no clustering of illnesses, no specific manifestations on chest imaging, and no positive nucleic acid test, this is generally not a case of novel coronavirus pneumonia.
