@Nutmeg031992 @covidtweets Was it with the original virus, or just the "1000x viral load" of delta, etc.?
Also, "Needed" is a bit unclear. I would define as say 50% likelihood, but you don't really see that discussed much.
That's likely going to vary a lot depending on ventilation, distance, etc.
@肉豆蔻031992@covidtweets是原始病毒还是delta的“1000倍病毒载量”等。？
此外，“需要”一词也有点不清楚。我会定义为50%的可能性，但你们并没有太多的讨论。
这可能会因通风、距离等的不同而变化很大。
