Agnes, what flight is direct from Liberia to DFW?
Hmm, lemme see.
Not finding any direct flights from here:

Course he could have flown somewhere else and then hopped. Hopefully he wasn’t symptomatic when he went through customs and the other airport. Contact tracing THAT would be a nightmare...
Forget Liberia. For oil, try Lagos to IAH.
