@MichaelSFuhrer If you are working from home AND avoiding restaurants (and similar), AND wearing a high quality well fitting mask everywhere else, you're probably reduced risk by MUCH more than 83% compared to "average" which is doing basically nothing.
@MichaelSFuhrer 如果您在家工作并且避免去餐馆（和类似场所），并且在其他任何地方都戴着高质量的合身口罩，那么与基本上什么都不做的“平均”相比，您的风险可能降低了 83% 以上。
