Results of environmental sampling of 2 rooms at a centralized quarantine hotel occupied by 2 presymptomatic SARS-CoV-2–infected patients, China, 2020*

Environmental source† Values‡
Patient A’s room Patient B’s room
Door handle 0/1 0/1
Light switch 1/1 (37.59) 0/1
Faucet 0/1 1/1 (28.75)
Bathroom door handle 1/1 (36.02) 0/1
Toilet seat, flush handle 0/1 0/1
Thermometer 0/1 0/1
TV remote 0/1 0/1
Pillow cover 1/1 (28.98) 1/1 (34.57)
Duvet cover 1/1 (35.64) 0/1
Sheet 1/1 (30.58) 0/1
1/1 (36.98)
Total, no. (%) 6/11 (54.5) 2/11 (18.2)

*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.
