Comparable Environmental Stability and Disinfection Profiles of the Currently Circulating SARS-CoV-2 Variants of Concern B.1.1.7 and B.1.351

The emergence of novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern with increased transmission dynamics has raised questions regarding stability and disinfection of these viruses. We analyzed surface stability and disinfection of the currently circulating SARS-CoV-2 variants B.1.1.7 and B.1.351 compared to wild type. Treatment with heat, soap, and ethanol revealed similar inactivation profiles indicative of a comparable susceptibility towards disinfection. Furthermore, we observed comparable surface stability on steel, silver, copper, and face masks. Overall, our data support the application of currently recommended hygiene measures to minimize the risk of B.1.1.7 and B.1.351 transmission.

Automated summary

Our analysis indicates that the currently circulating SARS-CoV-2 variants B.1.1.7 and B.1.351, as well as the wild type, show similar susceptibility to heat, soap, and ethanol disinfection. Additionally, all three variants exhibit comparable surface stability on materials such as steel, silver, copper, and face masks. Therefore, adherence to recommended hygiene measures is crucial in minimizing the risk of transmission of B.1.1.7 and B.1.351.
