To investigate whether our viruses show mutations different from other reported SARS-CoV-2, all the seven isolates were sequenced at the 3rd passage and the sequences were aligned with coding sequence (CDS) of SARS-CoV-2 Wuhan-Hu-1 (NC_045512). It is interesting to note that these seven patients infected with SARS-CoV-2 have high viral load in the early stage of clinical sign, which is consistent with previous reports (Kim et al. A The cytopathic effect was observed in Vero cells infected with the isolated viruses at 5 dpi. In conclusion, seven SARS-CoV-2 strains were isolated, sequenced and characterized in Vero cells, and a deletion mutation was identified after short passage in Vero cells.
