Confirmed cases of novel coronavirus infection from the clinical need to do a comprehensive judgment, to know whether the patient has an epidemiological history, epidemiological history includes many situations, the definition of epidemiological history is different at different times, but there must be a corresponding epidemiological history. Clinical manifestations are mainly fever, respiratory symptoms, the patient has imaging manifestations, CT has very typical imaging manifestations. If the above symptoms are met, a suspected case can be diagnosed, together with nucleic acid testing, if the nucleic acid is positive, the clinic is a confirmed case, so ultimately it depends on a positive nucleic acid to confirm the diagnosis.
