Mark was put on this cramped bus for a few hours.

Eventually, they boarded this cargo plane that would fly them all back home.

Mark was sitting up the front, a little further away from the sick passengers, but he could still hear them coughing.

And since this was a cargo plane, it wasn't designed for passengers, everyone on the flight, 170 people, were sharing two porta-potties.

Mark and some of the other passengers were eventually taken to Travis Air Force Base in California, where the U.S.

government told them they had to stay in quarantine before they could go home.

And it was at this point that Mark and the rest of the passengers were tested again for the virus.

So after all that, Mark was now infected.

And here's what's kind of bizarre, though.

Mark didn't feel sick.

In fact, he felt perfectly fine.

Did you have any symptoms at all?

Fever, a little cough?

Like, were you expecting symptoms to come at some point?

Weird.

So it's almost two months ago and you've never had symptoms.

So Mark cleared the infection.

He eventually tested negative and got out of quarantine.

And this means that if he never got tested, he would have never known that he was infected.

So how many people out there are like Mark?
