2-2- SARS-CoV-2 pathogen detection
Respiratory samples, including the nasopharyngeal and throat swabs, were
obtained from the enrolled patients. The SARS-CoV-2 primary detections
were performed using the standard real-time PCR method recommended by
CDC using Rotor-Gene-Q 6000 thermocycler (Corbett, Australia) according
to the recommended protocol 20. After the SARS-CoV-2
was confirmed in cases, the samples were stored in -70ÂșC for further
analysis.
