THỰC TRẠNG MẮC COVID-19 CỦA HÀNH KHÁCH NHẬP CẢNH TẠI CẢNG HÀNG KHÔNG QUỐC TẾ NỘI BÀI - HÀ NỘI, GĐ 2020-2022

Abstract

Objectives: To describe the COVID-19 infections among inbound passengers at Noi Bai International Airport - Hanoi during 2020-2022. Materials and method: A cross-sectional study, retrospective analysis of data from documents and records from passenger data sources at Noi Bai International Airport during the three years from 1/1/2020 to 31/12/2022. Results: There were 249 flights carrying passengers with COVID-19 out of 20,355 flights landing at Noi Bai. Most flights arriving at Noi Bai during all three periods originated from Asia. Out of 3,021,767 inbound passengers, 669 were identified as infected with SARS-CoV2, primarily Vietnamese (accounting for 69.1% of all passengers and 80.4% of those infected with SARS-CoV2). However, the COVID-19 infection rate per 100,000 passengers varied across the three periods and for flights arriving from different regions. The second period witnessed multiple waves of the pandemic, with the highest infection rate per 100,000 passengers recorded in June 2021 (1,197 passengers) and the highest infection rates among individuals with African (1,471), European (299), Vietnamese (290), and American (144) nationalities. Conclusion: Understanding the global pandemic situation, the infection rate in each stage and at specific points in time and analysing the characteristics of inbound passengers at Noi Bai Airport is crucial for developing relevant strategies and plans for each pandemic stage. It is essential to ensure preparedness and readily available measures to respond to future pandemics. This will ensure proactive prevention and control of disease entry and prevent large-scale outbreaks that could negatively impact the economy and society.
