But the reality is that travelers are boarding planes with covid-19, putting their fellow passengers at risk of contracting the illness. Doctors say flying is a high-risk activity for covid-positive individuals because of low air pressure in the cabin, and that multiple passengers have now died because of it. Covid-19, the illness caused by the novel coronavirus SARS-CoV-2, is a respiratory disease that often attacks the lungs and heart. Flying has long given respiratory-troubled patients medical crises in the air. Covid-19 is no different; flying with it can impact blood oxygen levels to a degree that requires immediate medical attention.
