Pentagon study finds minimal risk of coronavirus exposure on planes

A Defense Department study released Thursday concluded that passengers faced little risk of catching the coronavirus on a packed commercial flight. Researchers concluded that a passenger wearing a surgical mask continuously would have to sit next to an infectious passenger for 54 hours to get a dangerous level of exposure through the air. The threat of infection is greatly reduced because of the way air is circulated and filtered on airliners.
The study used a mannequin expelling simulated virus particles, and researchers conceded that this method of measuring the threat of aerosol exposure had its limitations. Still, Vice Adm Dee Mewbourne said, "the results showed an overall low exposure risk from aerosolized pathogens like COVID-19 on these aircraft."
