2, the patient has clinical manifestations such as fever, dry cough, malaise, etc., lung imaging with patchy shadow and interstitial changes, or routine blood tests showing normal or reduced total white blood cell count, or reduced lymph node cell count.
3, on the basis of the above, a novel coronavirus nucleic acid test is performed, and a positive patient can confirm the diagnosis.
