Title: 使用考虑乘客移动的模型识别航班上新冠超级传播的缓解策略

Abstract: Despite commercial airlines mandating masks, there have been multiple documented events of COVID-19 superspreading on flights. We used available data from three flights, including cabin layout and seat locations of infected and uninfected passengers, to suggest interventions to mitigate COVID-19 superspreading events during air travel. Specifically, we studied: 1) London to Hanoi with 201 passengers, including 13 secondary infections among passengers; 2) Singapore to Hangzhou with 321 passengers, including 12 to 14 secondary infections; 3) a non-superspreading event on a private jet in Japan with 9 passengers and no secondary infections. We show that inclusion of passenger movement better explains the infection spread patterns than conventional models do. We also found that FFP2/N95 mask usage would have reduced infection by 95-100%, while cloth masks would have reduced it by only 40-80%. This suggests the need for more stringent guidelines to reduce aviation-related superspreading events of COVID-19. Show Chinese abstract

Abstract: 尽管商业航空公司要求佩戴口罩，但已有多个记录在案的事件表明，在航班上发生了新冠病毒超级传播。 我们使用了三架航班的可用数据，包括客舱布局和感染乘客与未感染乘客的座位位置，以提出干预措施，以减轻航空旅行中的新冠病毒超级传播事件。 具体来说，我们研究了：1）伦敦至河内的航班，有201名乘客，其中13人出现次级感染； 2）新加坡至杭州的航班，有321名乘客，其中12至14人出现次级感染；3）日本一架私人喷气式飞机上的一次非超级传播事件，有9名乘客且没有次级感染。 我们表明，将乘客移动纳入考虑能比传统模型更好地解释感染传播模式。 我们还发现，使用FFP2/N95口罩可以将感染减少95-100%，而布料口罩仅能减少40-80%。 这表明需要更严格的指南来减少与航空相关的新冠病毒超级传播事件。
