The odds of catching Covid-19 on an airplane are slimmer than you think, scientists say “Similarly, the mannequin remained facing forward, uncertainty in human behavior with conversations and behavior may change the risk and directionality in the closest seats to an index patient, especially for large droplets.” “Testing did not include substantial movement throughout the plane or in the airport, lounge or jetway, where air change rates and human interactions will vary,” the researchers added. Other reports have found people became infected with coronavirus on flights, perhaps when they took off masks to use restrooms. “These alternative routes of exposure are more challenging to predict because of uncertainty in human behavior.” “Contamination of surfaces via non-aerosol routes (large droplets or fecal contamination) is more likely in lavatories and other common areas and is not tested here,” they added. “Testing assumes that mask wearing is continuous, and that the number of infected personnel is low,” the research team wrote. Is it safe to travel for the holidays this year? They were sucked quickly into the ventilation system, the team concluded, and were unlikely to contaminate nearby surfaces or blow into the breathing zones of people seated nearby. The team used fluorescent aerosol tracers to see where particles emitted from the coughing “passenger” went. The US Transportation Command, The Defense Advanced Research Project Agency (DARPA) and the Air Mobility Command used Boeing 777-200 and 767-300 aircraft loaded up with sensors meant to duplicate the effect of a fully loaded passenger flight.Ī dummy wearing a surgical mask simulated a coughing passenger infected with a respiratory virus. The study, which was released without peer review, did not take into account other ways that people could catch the virus on aircraft – including from others coughing or breathing directly on them, from surfaces or from confined spaces such as restrooms. The US Department of Defense study supports earlier research showing the ventilation systems on aircraft filter the air efficiently and take out particles that could transmit viruses. A new study released Thursday suggests that people don’t need to worry about circulating air spreading coronavirus on airplanes.
