| Ceramic tile | Non-porous | |
| Float glass | Non-porous | |
| Low-density polyethylene | Non-porous | |
| Melamine resin | Non-porous | |
| Non-woven mask (polypropylene) | Porous | |
| Polypropylene | Non-porous | |
| Polystyrene | Non-porous | |
| Stainless steel SUS430 (buff polishing) | Non-porous | |
| Rapidly decreasingb | Brass C2801 (buff polishing) | Non-porous |
| Lauan veneer | Porous | |
| Nitrile rubber | Non-porous | |
| Soft polyvinyl chloride | Non-porous | |
| Maintain at low levelc | Copy paper | Porous |
| Polyester cloth | Porous |
aThe recovery of infectious virus from the surface at 0 h after drying of the viral inoculum was not strongly decreased, and the recovery of infectious virus from the surface was maintained for a relatively long term.
bThe recovery of infectious virus from the surface at 0 h after drying of the viral inoculum was not strongly decreased, however, the infectious virus immediately died. Alternatively, the recovery of infectious virus from the surface at 0 h after drying of the viral inoculum was strongly decreased, and the infectious virus immediately died.
cAlthough the recovery of infectious virus was strongly decreased at 0 h after drying of the viral inoculum, it was maintained for a very long time at a low concentration.
