Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is causing the global coronavirus disease 2019 (COVID‐19) pandemic. Because complete elimination of SARS‐CoV‐2 appears difficult, decreasing the risk of transmission is important. Treatment with 0.1 and 0.05 ppm ozone gas for 10 and 20 hr, respectively, decreased SARS‐CoV‐2 infectivity by about 95%. The magnitude of the effect was dependent on humidity. Treatment with 1 and 2 mg/L ozone water for 10 s reduced SARS‐CoV‐2 infectivity by about 2 and 3 logs, respectively. Our results suggest that low‐dose ozone, in the form of gas and water, is effective against SARS‐CoV‐2.

通过臭氧气体和水的容许浓度降低严重急性呼吸综合征冠状病毒-2的传染性

严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 正在导致 2019 年全球冠状病毒病 (COVID-19) 大流行。由于完全消除 SARS-CoV-2 似乎很困难,因此降低传播风险很重要。分别用 0.1 和 0.05 ppm 臭氧气体处理 10 小时和 20 小时,将 SARS-CoV-2 的传染性降低了约 95%。影响的大小取决于湿度。用 1 和 2 mg/L 的臭氧水处理 10 秒后,SARS-CoV-2 的传染性分别降低了约 2 和 3 个对数。我们的研究结果表明,气体和水形式的低剂量臭氧对 SARS-CoV-2 有效。
