Most of the newly crowned infected patients are mild patients or asymptomatic infected patients tend to have no sequelae, while severe and critical patients may have sequelae such as pulmonary fibrosis and decreased lung function. Asymptomatic infected patients and mild patients have a better prognosis with active treatment, while severe and critical patients may have severe and irreversible pulmonary fibrosis, which may subsequently be accompanied by generalized weakness, dyspnea, and restrictive ventilatory disorders. Novel coronavirus pneumonia is an acute infectious pneumonia that manifests itself in fever, dry cough, malaise, runny nose, nasal congestion, decreased sense of smell, conjunctivitis, muscle pain, diarrhea, and other discomforts.
