Comparison of studies on environmental SARS-CoV-2 done in UK hospitals
| Study | Location | Air concentration (copies/m3) | Surface levels |
|---|---|---|---|
| This study | Three hospitals in Scotland | <30 to 1717 copies/m3 15% positive |
<160 to 19,168 copies/swab <1.49 to 319 copies/cm2 16% positive |
| Moore et al. [5] | Eight hospitals in England | <10 to 460 copies/m3 7% positive |
59 to 2.2 × 105 copies/swab 9% positive |
| Zhou et al. [7] | One hospital in London, UK | 31 to 7048 copies/m3 11% positive |
∼101 to 104 copies/swab ∼0.4 to 400a copies/cm2 52% positive |
