@ems_jn Here's another study of in-flight transmission, exhaustively contact traced and confirmed with genomic sequencing. Passengers infected all seated near each other showing the effects of short range transmission. Airplane ventilation isn't sufficient.

@ems_jn这是另一项关于飞行传播的研究，通过基因组测序进行了详尽的接触追踪和确认。所有受感染的乘客都坐得很近，显示出短程传播的影响。飞机通风不足。
