Virucidal efficacy of hydrogen peroxide vapour (HPV) against viruses dried on stainless steel discs
| Virus (strain) | Log10 reduction in virus titre (TCID50)a (SD) after exposure to vaporized volumes of hydrogen peroxide |

|---|---|---|---|
| 25 mLb | 27 mLb | 33 mLb | |
| Human adenovirus (type 1) | >5.61 (0.19) | >5.61 (0.51) | >4.83 (0.33) |
| Feline calicivirus (strain 255) | >5.94 (0.51) | >6.28 (0.39) | >6.16 (0.00) |
| TGEV (Purdue, type 1) | >5.05 (0.19) | >4.94 (0.19) | >5.28 (0.69) |
| Avian influenza virus (H9N9) | >4.08 (0.58) | >4.50 (0.25) | >4.83 (0.29) |
| Swine influenza virus (H3N2) | >3.83 (0.14) | >4.92 (0.63) | >4.75 (0.50) |
TCID50, transmission culture infective dose; TGEV, transmissible gastroenteritis coronavirus; SD, standard deviation.
a
Log10 reduction calculated by comparing the virus titre recovered from the control and HPV-exposed discs.
b
No virus particles were detected on the test discs.
