@EroticaGood @mikejohansenmd @19joho This is a really good point, not repeated often enough, and also given that large metro areas are also travel hubs it is quite plausible that earlier outbreaks which are noticed in a large metro could have come from far or very far away.
@EroticaGood @mikejohansenmd @19joho 这是一个非常好的观点，重复的次数不够多，而且考虑到大型地铁区域也是旅游枢纽，在大型地铁中发现的早期爆发可能来自很远或很远的地方。远处。
