Table 1.
Best-fit parameters of the bi-exponential model (Eq. 1) of measured airborne MNV and human influenza A (H1N1) dose-dependent surviving fraction.
| Virus (strain) | Best-fit parameter estimate ± SE | D90 (mJ cm−2) | ||
|---|---|---|---|---|
| k1 susceptibility constant for “sensitive” population (cm2 mJ−1) | k2, susceptibility constant for “resistant” population (cm2 mJ−1) | % resistant population | ||
| Murine norovirus (CW1) | 2.36 ± 0.63 | 0.35 ± 0.06 | 8.5 ± 4.6 | 0.98 |
| Human influenza A (H1N1) (A/PR/8/34) | 20.06 ± 8.04 | 2.30 ± 0.62 | 6.0 ± 4.0 | 0.11 |
| Human betacoronavirus 1 (OC43) | 12.4 ± 0.04 | 1.6 ± 0.1 | 0.31 ± 0.054 | 0.19 |
The experiments were performed in a benchtop system with the viruses exposed to different doses of 222 nm far-UVC light. Values for human coronavirus OC43 were obtained previously41.
