Cough is one of the main symptoms of novel coronavirus infection, which is often dry and without sputum. In addition, patients may have fever, general malaise and malaise, and some patients may have nasal congestion, runny nose, diarrhea, nausea, headache, and general muscle aches. Patient symptoms are often nonspecific and very similar to those caused by viral colds, so it is important to make a good differential diagnosis. For people who have a history of typical exposure or who travel, work, study or live in endemic areas, novel coronavirus infection can be highly suspected and testing at fever clinics in various hospitals is recommended. The diagnosis can be confirmed if the patient meets the criteria for suspected infection and the pathogenic test for novel coronavirus is positive.
