Abstract
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.
摘要
新型严重急性呼吸系统综合征冠状病毒 2（SARS-CoV-2）变种的出现，其传播动态增加，引发了关于这些病毒稳定性和消毒的问题。我们分析了目前流行的 SARS-CoV-2 变体 B.1.1.7 和 B.1.351 与野生型相比的表面稳定性和消毒情况。热、肥皂和乙醇处理显示出相似的失活动力学，表明对消毒的敏感性相当。此外，我们还观察到在钢、银、铜和口罩上具有相似的表面稳定性。总的来说，我们的数据支持应用目前推荐的卫生措施，以最大程度地降低 B.1.1.7 和 B.1.351 传播的风险。
