The SARS-CoV-2 RNA test of all three patients was positive before being admitted to hospital. The results of SARS-CoV-2 RNA test during the two periods of hospitalization were shown in Table 1 . Although no special discomfort was found, all patient's nasopharyngeal swab test of SARS-CoV-2 RNA were positive during the isolation. The detoxification procedure does occur which will cause re-detectable positive SARS-CoV-2 RNA in recovered COVID-19 Accepted Article patients [6] . However, these patients re-detectable positive for SARS-CoV-2 RNA displayed high levels of IgG and negative IgM in the plasma during two hospitalization periods.
