Numbering of environmental sites corresponds to the numbering in the eFigure in the Supplement.
Results are shown as number of positive samples/number of total samples. All samples taken from patients A and B after routine cleaning were negative and not included in this table.
Cycle threshold refers to the number of cycles required for the fluorescent signal to cross the threshold in RT-PCR; a lower cycle threshold value indicates a higher viral load.
One swab was taken from each site except the air outlet fan, from which 3 swabs were taken.
