@OptimisticCon Dozens or even handfuls of cases in a small county, say population 10k is NOT a small number. In such a small county it would be easily possible to have zero reported cases, and this has happened in the past. It doesn't happen much now because there is a LOT of virus about.
@乐观主义者认为，在一个小县里，10万人口并不是一个小数字。在这样一个小的县，很容易就没有报告病例，而这在过去已经发生过。现在这种情况发生得不多，因为有很多病毒。
