I don't think there are any direct flights to Dallas from Brussels.

The patient either transferred from Europe or another American city.

Travelocity loads lots of direct flights from Brussels to Dallas. Try it.

Oop, just read the fine print. Those go through London.

Which is worse. If he was symptomatic but still mobile, like Patrick Sawyer, that means the flight from Monrovia to Brussels is suspect as are the bathrooms and waiting areas in Brussels. And the flight from Brussels to London and its associated bathrooms and seat handles. And the concourses in London and their associated bathrooms and waiting areas. And the flight to Dallas, etc.
