So the second plane that he flew on has gone to Mexico City, DC, LA, and Las Vegas in the days after that. The CDC had better be right about him not being contagious. If he coughed on the seats near him, and the virus lasts for 8 days on surfaces that aren’t disinfected immediately, then, Houston, we have a problem.
I haven’t even checked on where the first flight from Brussels has been.
This is real life “12 Monkeys” stuff.
