@sejwatson @apmalong @sameo416 No, I don't. I've seen numbers from 50 to 1000 and maybe even outside of that range. Also may depend on the nature of the particles (larger particles may contain more virus but behave differently from smaller particles). Seems to be a lot of uncertainty around this.
@sejwatson @apmalong @sameo416 不，我没有。我见过从 50 到 1000 的数字，甚至可能超出这个范围。也可能取决于颗粒的性质（较大的颗粒可能含有更多的病毒，但与较小的颗粒表现不同）。这似乎有很多不确定性。
