droplet precautions are three feet.
“droplet precautions are three feet.”
Years ago, when the fuel crisis hit, commercial planes started flying with their fresh air vents closed, as it saved fuel. An FAA study, published, as I recall, in Aviation Week, said that in a four hour flight all passengers would be exposed to an airborne virus if the virus carrier was active. I don’t know if airborne viruses travel in droplets or not. Nor do I know where the air returns are on planes. But I’d imagine the ventilation system would pick them up and move them farther than three feet.
