  • Following a 10-hour flight from London, UK to Hanoi, Vietnam on March 2, 2020, 16 of 217 passengers (7%) were found to be positive for SARS-CoV-2 after contact tracing, of whom 12 (75%) were seated in business class along with the only symptomatic person (attack rate 62%). Seating proximity was strongly associated with increased infection risk (OR=7.3).
