Author Interviews, COVID -19 Coronavirus / 16.10.2020 Interview with: Shane Riddell MSc CSIRO—Australian Animal Health Laboratory Geelong, Australia What is the background for this study? What are the main findings? Response: While it is generally considered that SARS-CoV-2 is spread via aerosol and respiratory droplets, we still need to investigate how much of a role fomites play in transmission. Understanding the risk first requires you to know how long the virus can survive on a surface. We therefore wanted to assess how long the virus would remain viable on various common surfaces such as stainless steel, glass and banknotes. We found that, under controlled conditions, we could recover infectious virus at 28 days for all non-porous surfaces at 20 degrees Celsius. When the temperature was raised to 40 degrees Celsius, SARS-CoV-2 only remained viable for 24hrs on most surfaces. (more…)
