Here’s the part most people never get explained.
You don’t usually get sick when you fly.
You get sick days later.
That delay is exactly what makes this so frustrating.
Because by the time symptoms show up, the exposure already happened.
Not at home.
Not at the office.
Not when you “let your guard down.”
During travel.
Airports. Planes. Crowded cabins. Long flights.
Which leads to a dangerous assumption most travelers make:
“If I don’t feel sick during the flight, I must be fine.”
Unfortunately, that’s not how exposure works.
