https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7543400/ It's not a study from the US but it includes enough flights where there were confirmed index cases and there were 4 levels of masking rigidity. The case we're describing, where people only unmask to eat, there were no transmissions. > On flights N–R with the rigid masking policies (meals served) of Emirates Airlines, no secondary cases were identified on Day 14 screening despite 58 passengers who were PCR+ on a total of 5 flights of 8 hours each with ~1500–2000 passengers. |
