@OptimisticCon Look to make clear, 30 infections out of say 100 people would absolutely be extremely high. It's rampant in that population. 30 infections per day in a rural county (say 10k) if it is consistent over time is likewise high.
@乐观主义者希望弄清楚，100人中有30人的感染率绝对会非常高。它在那群人中很猖獗。一个农村县每天30例感染（比如10万例），如果持续时间长，感染率同样高。
