There are various methods for detection of novel coronavirus, including lung CT examination and viral nucleic acid testing. Novel coronavirus test is an RNA virus and should be performed if there is a history of travel to the infected area or contact with related persons 14 days before the onset of the disease, symptoms of upper respiratory tract infection such as fever and cough, imaging features of pneumonia on chest radiography, and reduced lymphocyte count on routine blood tests. Real-time fluorescent RT-PCR of respiratory specimens or blood specimens can be used to detect novel coronaviruses, and a positive nucleic acid can confirm the diagnosis. Viral gene sequencing of respiratory specimens or blood specimens with a high degree of homology to known novel coronaviruses may also be used to confirm the diagnosis.
