*Values are no. positive/total (Ct) except as indicated. Ct, cycle threshold; rRT-PCR, real-time reverse transcription PCR; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
†One swab was taken from each site except the light switch, from which 2 swabs were taken.
‡All samples taken from patients A and B after disinfection were negative and not included in this table. A lower Ct indicates a higher viral load. Only Ct values for open reading frame 1ab (ORFab1) gene of SARS-CoV-2 were provided because the Ct values for nucleoprotein were similar to those of ORFab1.
