背景：2020年1月24日至2020年2月15日期间，从新加坡飞往杭州的航班上的335名乘客发生了COVID-19疫情。本研究旨在调查疫情来源，评估COVID-19在飞行中传播的风险。方法：采用标准化问卷，收集旅客在飞行前、飞行中、飞行后的人口学特征和疾病情况。我们还收集了与COVID-19在飞行中传播可能相关的因素的数据。结果：所有旅客中共诊断出新冠肺炎患者16例；总体攻击率为4.8%。从武汉出发的旅客发病率明显高于从其他地方出发的旅客。1名登机前无流行病学接触史的乘客感染了COVID-19。在飞行过程中，他在四名来自武汉的感染乘客附近坐了大约一个小时，并且在飞行过程中没有正确佩戴口罩。结论：COVID-19可能是在飞行过程中传播的。然而，与航班相关的疫情中的大多数病例不能归因于航班上的传播，而是与在武汉接触该病毒或在一个旅游团中感染该病毒的成员有关。
Background: Between January 24, 2020 and February 15, 2020, an outbreak of COVID-19 occurred among 335 passengers on a flight from Singapore to Hangzhou in China. This study aimed to investigate the source of the outbreak and assess the risk of transmission of COVID-19 during the flight.Method: Using a standardized questionnaire, we collected information on the travelers' demographic characteristics and illness before, during, and after the flight. We also collected data on factors potentially associated with COVID-19 transmission during the flight.Results: A total of 16 COVID-19 patients were diagnosed among all passengers; the overall attack rate was 4.8%. The attack rate among passengers who had departed from Wuhan was significantly higher than that among those who had departed from other places. One passenger without an epidemiological history of exposure before boarding developed COVID-19. During the flight, he was seated near four infected passengers from Wuhan for approximately an hour and did not wear his facemask correctly during the flight.Conclusions: COVID-19 transmission may have occurred during the flight. However, the majority of the cases in the flight-associated outbreak could not be attributed to transmission on the flight but were associated with exposure to the virus in Wuhan or to infected members in a single tour group.
