某航站楼国际到港区呼吸道传染病传播风险分析及应对策略——以新冠肺炎为例

Regional Infection Risk Involved International Passengers and Response Strategies in an International Arrival Area of a Terminal:A Case Study of COVID-19

以某机场航站楼的国际到港区域为研究对象,基于改进的Wells-Riley模型预测各区域不同人群感染呼吸道传染病的风险,结果表明:航站楼因其各区域功能特点的不同,感染概率存在较大差别,并且大多区域如通道、座椅区的感染概率普遍低于1%,机场的综合防疫措施取得了较好成效。根据风险识别结果特别提出了重点防范区域气流组织控制的方法。总结了新冠疫情时期某国际机场的应对策略,风险等级划分、旅客流程调整、特殊空间改造等措施对大型国际枢纽机场航站楼应对类似重大公共卫生事件具有一定借鉴意义。

The international arrival area of an airport terminal is researched.The infection risk in each region is predicted based on the improved Wells-Riley model,and the results showed that the infection probability of the terminal was quite different due to the different functional characteristics of each region,and the infection probability of most areas such as passage and seat area was generally less than 1%,and the comprehensive epidemic prevention measures of the airport achieved good results.According to the risk identification results,a method of key prevention area airflow organization control is proposed.The response strategies of an international airport during COVID-19 epidemic period are summarized,and measures such as risk classification,passenger flow adjustment,and special space transformation have certain reference significance for large international hub airport terminals to respond to similar major public health emergencies.
