Transmission and Inactivation of SARS-CoV-2 - Eike Steinman, PhD
Professor Eike Steinmann discusses the transmission of SARS-CoV-2, the virus which causes COVID-19. Both alcohol and soap can deactivate the virus. Soap can be used in home settings. Soap both mechanically removes the virus and deactivates the virus's protein lipid capsule. The major mode of transmission of SARS-CoV-2 is by aerosolization. Transmission by surfaces is also possible and experimentally the virus has been shown to be infectious on plastic and stainless-steel surfaces for up to three days. However, the touch transfer assay, a more realistic method of studying viral infectivity, was not able to demonstrate transfer of an infectious virus when it had dried on surfaces. It is felt that surfaces are not a major method of transmission with SARS-CoV-2. Health Watch USA(sm) Webinar, Frontline Worker Safety in the Age of COVID-19: A Global Perspective.
