Table 2. 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 |
| Towel |
1/1 (36.98) |
0/1 |
| 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.
