Why can airplane travel expose you to a high concentration of germs if airlines say the area is cleansed with filters and the plane is cleaned regularly ?
In: Biology
Yes, the air is somewhat filtered and the airplane is cleaned between flights. It’s still typically a couple hundred people stuffed into a relatively small tube, mostly with maybe a few inches between each of them and at least one other person. Even if every surface in the plane was sanitized to the point of being completely sterile before passengers get on (it’s far from it), hundreds of people get onto it with a lot of germs to share with each other.
