@Spudstar1 @MartinKulldorff Sure. Transmission risk is cumulative over an extended period. It's not like when someone takes off the mask to eat this immediately infects the whole plane.
Also, vulnerable or cautious people who need to eat or drink can choose to do so when others are not eating and masked.
@Spudstar1@MartinKulldorff当然。传播风险在很长一段时间内是累积的。这不像是有人摘下口罩吃东西会立即感染整个飞机。
此外，需要进食或饮水的脆弱或谨慎的人可以在其他人不进食和戴口罩时选择进食或饮水。
