The risk of COVID-19 infection on flights is 'very low,' and 1 infected passenger would take 54 hours to spread the virus to others onboard, a US government study found
Two crossed lines that form an 'X'. It indicates a way to close an interaction, or dismiss a notification.Research commissioned by the US Department of Defense has found the risk of getting infected by airborne COVID-19 on flights is "very low."
If only one passenger on a Boeing 767 or 777 flight is infected, it would take a flight of around 54 hours for others onboard to get an infectious dose of the virus, researchers found.However, researchers acknowledged that the test was limited because it was based on the flight having just one infected passenger, and didn't involve passengers moving around the cabin.
Mannequins with and without face masks sat throughout the aircraft during both ground and in-flight tests. Fluorescent aerosol tracer particles were released at two-second intervals to simulate an infected passenger breathing. On average, the tracer particles remained detectable within the cabin for less than six minutes. In a typical American home, this figure would be around 90 minutes, researchers said.
USTRANSCOM invested in the study to see if its COVID-19 safety measures are providing the safest possible means of transportation.
