Evidence on the risk of COVID-19 transmission in flight: update 3 - Last Updated Jan 23, 2024
This is a great meta-analysis for those interested in tabulating the risks of flying. I can't post everything here; the site has dozens of links.
Introduction
What is the evidence on in-flight transmission of COVID-19, assessments of risk, and mitigation strategies related to air travel?
Many changes have been implemented by airlines and national government during the pandemic to reduce the risk of SARS-CoV-2 transmission during air travel. This evidence brief summarizes the literature on in-flight transmission of SARS-CoV-2, the characteristics of these events, and the strategies implemented or proposed to mitigate transmission in an airplane or during boarding and disembarkation. This is the third update and includes studies up to November 25, 2021. The first and second update of this review contained literature published up to October 28, 2020 and April 26, 2021, respectively.
What's new
Highlights from the current literature include:
Twenty-five additional studies were added in this update; twelve flight investigations (Table 1), five reviews, one passenger/crew survey on infection and prevention measures, two risk assessments (Table 2), and five simulation studies on reduction of respiratory virus spread and the relative impact of mitigation strategies during air travel (Table 3). These new studies bring the total number of studies included in this review to 84.
Overall, attack rates (AR) were low (0-10%) except for two new reports of super-spreading events caused by variants of concern (VOCs) or former variants of interest (VOIs) (AR: 16-40%).
The findings from the new studies further substantiate results from the previous updates.
