The diagnosis of novel coronavirus pneumonia requires a combination of epidemiological history, clinical manifestations and laboratory tests. Patients usually present with typical symptoms such as fever, malaise, dry cough, and in severe cases, respiratory distress. Patients have a reduced or normal white blood cell count and a reduced lymphocyte count on blood tests at the beginning of the disease, and most patients will have elevated CRP and hematocrit. Novel coronavirus nucleic acids can be found in the patient’s pharyngeal swabs and respiratory secretions. When chest imaging is performed, patients may have small patchy shadows and interstitial changes in the early stages, and as the disease progresses, they may show multiple ground glass shadows in both lungs, and patients with severe disease may have solid lung changes.
