The most prominent and typical symptom of novel coronavirus infection is fever, and it usually appears as the first symptom of this viral infection. Generally, it occurs within 14 days of a typical exposure history, and patients with a temperature of 37.3°C or higher for about 2 days should promptly visit a fever clinic anywhere.
First, a CT (or X-ray) of the lungs and routine blood tests should be done, and if they are consistent with typical viral pneumonia manifestations, further pathogenic tests should be done, and a positive result will confirm the diagnosis.
