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
In addition to what other people said, before you get on the plane, you have to go through an airport, which is not cleaning surfaces or filtering the air as much as they do on the plane. If you get sick after a trip, you won’t know whether you got sick on the plane or at the airport.
