Non-therapeutic interventions such as practicing good hand hygiene continue to be the mainstay of protection from SARS-CoV-2 and other emerging respiratory viruses.
We have evaluated a range of commercially available personal care products including soaps, handwash liquids and alcohol-based hand sanitizers for antiviral efficacy against a clinical isolate of SARS-CoV-2 using internationally accepted standardized protocols at user-relevant contact time-points and product dilutions.
All the tested products resulted in 3 to 4 log reduction of SARS-CoV-2 titer.
Our data re-affirms recommendations by global public health authorities that proper hand hygiene can reduce SARS-CoV-2 viral load significantly which should likely limit spread of the contagion.
非治疗性干预措施，如保持良好的手部卫生，仍然是预防 SARS-CoV-2 和其他新兴呼吸道病毒的主要手段。
我们评估了一系列市售的个人护理产品，包括肥皂、洗手液和酒精基洗手液，使用国际公认的标准化方案，在用户相关的接触时间点和产品稀释度下，针对 SARS-CoV-2 的临床分离株评估其抗病毒功效。
所有测试的产品均使 SARS-CoV-2 滴度降低了 3 到 4 个对数级。
我们的数据再次证实了全球公共卫生当局的建议，即正确的手部卫生可以显著降低 SARS-CoV-2 的病毒载量，从而可能限制传染的传播。
