Abstract

In their article, Bundgaard and colleagues report the results of a unique randomized controlled trial of masks in the community to mitigate SARS-CoV-2 infection. The trial addresses the question of personal protection to mask wearers when others are not wearing masks and not the question of the effectiveness of widespread mask wearing in reducing community transmission. The editorialists discuss the findings and their concerns about the trial design.

摘要

在他们的文章中,Bundgaard 及其同事报告了一项在社区中使用口罩来减轻 SARS-CoV-2 感染的独特随机对照试验结果。该试验解决了在他人不戴口罩时口罩佩戴者的个人保护问题,而不是广泛戴口罩在减少社区传播方面的有效性问题。社论作者讨论了试验设计及其对试验结果的担忧。
