@BestinthePNW_ @D28EquityNow @drlucymcbride @kprather88 A very significant portion of transmission is in the day or two before symptoms, and many early symptoms are ambiguous (tickle in throat, start of a headache, slight congestion) and many will reasonably ignore them since 90% of the time they are nothing.
@Bestin PNW_@d28 EquityNow@drlucymcbride@kprather 88传播的很大一部分是在症状出现前一两天，许多早期症状都是模糊的（喉咙发痒、头痛开始、轻微充血），许多人会合理地忽略它们，因为90%的时间它们都是无关紧要的。
