I mean, how much is that nonsymptomatic transmission as a percentage of total transmission?

我的意思是，非症状传播占总传播的百分比是多少？

And so if you add in the never symptomatic to the presymptomatic, do you get above 50 percent of the transmission is actually from nonsymptomatic people?

因此， 如果将无症状的人加到有症状的人身上，是否有超过 50% 的传播实际上来自无症状的人？
