@antizeroalt @MikeBromley15 @thumbhatguy @NKinNewEng @macroliter There are numerous known transmission events planes and busses, fewer on trains I think. Lots of places simply don't trace well enough to know. Data also muddied by times and places where community transmission was low or vaccines effective against transmission.
@antizeroalt@MikeBromley15@thumbhatguy@NKinNewEng@macrolel有许多已知的传输事件飞机和公共汽车，我认为火车上的传输事件更少。许多地方根本没有足够的线索来了解。数据也因社区传播率低或疫苗有效预防传播的时间和地点而变得混乱。
