Looking just at the headline, you only know that he was an airline passenger and not abroad. Too, you know immediately that he was in an airliner - a small metal tube, with hundreds of people breathing the same air!

It's actually a pretty masterful headline, in that it doesn't actually come out and say any of that. It seems calm and fairly accurate, but is worded very carefully to encourage fear.

Nothing accidental there.

Until he was symptomatic, 4 days after arriving, he wasn't infectious. Or so we believe, with a fair amount of data; obviously we'll be drastically extending our knowledge over the next few years.

Sure, but that's not the point. The headline is subtly encouraging people to think of it as I described.
