But the results of that model are not matching what we see in China, and so very likely, there aren't as many of these infecting asymptomatics.

但该模型的结果与我们在中国看到的不符，因此很可能没有那么多的无症状感染者。

So that's a great question, and, as you know, we don't fully understand the epidemiology of this virus, but there is some sense that there may be asymptomatics.

SB：所以这是一个很好的问题， 正如你所知，我们并不完全了解这种病毒的流行病学， 但从某种意义上说， 可能存在无症状。
