So when someone actually goes on a plane, they could be sick and they could actually be in this latency period in which they could actually have the disease but not exhibit any symptoms, and they could, in turn, spread the disease to many other people in the cabin.
Så når nogen stiger på et fly, kan de være syge og de kunne faktisk være i den latens periode hvor de har sygdommen men ikke viser nogen symptoner, og de kan sprede sygdommen til mange andre i flyet.
