@mamasaurusMeg @smitty8234 @violin_health @WADOHIssues @DocJeffD @KCPubHealth @masknerd No, that is based on physical testing. And I doubt the 90% is accurate on the basis of volume of emissions and viral load either. I've recently seen claims from experts that majority is 1-5, but I don't really know, and highly doubt you do.
@mamasaurusMeg @smitty8234 @violin_health @WADOHIssues @DocJeffD @KCPubHealth @masknerd 不，这是基于物理测试的。而且我怀疑 90% 是否基于排放量和病毒载量是准确的。我最近看到专家声称大多数是 1-5，但我真的不知道，并且非常怀疑你知道。
