但是节目中没有楼主这么多推论，但是倾向于早期病毒在美国就已经出现。

这个网页是CDC关于电子烟导致 lung injury的新闻通稿。其中的最后一段话中的一句是“And since the specific cause or causes of lung injury are not yet known, the only way to assure that you are not at risk while the investigation continues is to consider refraining from use of all e-cigarette and vaping products. ”说明当时并没有查明致死的原因，只有推论。过后就基本是没有关于此类的新闻了。而且当时患者也是迅速死亡
The CDC reported 2,807 confirmed hospital cases of severe respiratory illnesses as of Feb. 18, among those who vaped nicotine or cannabis products in 50 states, D.C. and two U.S. territories. 68 people have died from a lung injury associated with e-cigarette use in 29 states and the District of Columbia, the Centers for Disease Control and Prevention reports as of Feb. 18.
我贴出这段话只是想指出致死率和新冠状病毒的比较接近。
