The data presented in a study demonstrates that infectious SARS-CoV-2 can be recovered from non-porous surfaces for at least 28 days at ambient temperature and humidity (20 °C and 50% RH). Increasing the temperature, while maintaining humidity, drastically reduced the survivability of the virus to as little as 24 h at 40 °C. SARS-CoV-2 survivability on hospital PPE observed viable virus up to 21 days post inoculation on both plastic and N95 mask material when held at room temperature.

Common Surfaces tested in the study:
Polymer bank notes, de-monetised paper bank notes, surfaces including brushed stainless steel, glass, vinyl and cotton cloth. Stainless steel is used in kitchen areas and public facilities; Glass prevalent in public areas, including hospital waiting rooms, public transport windows and shopping centres; high contact surfaces such as mobile phone screens, ATMs and self-serve check-out machines; Vinyl used in social settings, tables, flooring, grab handles on public transport, as well as mobile phone screen protector material; Cotton in clothing, bedding and household fabrics.
Result:
The data presented in this study demonstrates that infectious SARS-CoV-2 can be recovered from non-porous surfaces for at least 28 days at ambient temperature and humidity (20 °C and 50% RH). The persistence of both SARS and SARS-CoV-2 on cotton has been demonstrated to be significantly shorter than on non-porous surfaces. The data presented in the study also shows a significant decrease in titre of recovered virus after just 1 h drying at room temperature (20 °C) the amount of virus recovered from cotton swatches was approximately 99% less than for comparable virus recovery time points for non-porous material. SARS-CoV-2 persists on both paper notes and polymer notes to at least 28 days at 20 °C, albeit with a faster rate of inactivation on polymer notes.
