Yes, you're right. I did see the possible Saudi case but forgot to add it. Also, the Saudis announced that they will not be issuing Haj visas to Liberia, Guinea, and Sierra Leone. Emirates announced it was suspending flights to those countries, while Air France, British Airways and Lufthansa said they were merely "screening" passengers.
British Airways suspended all flights to and from Liberia and Sierra Leone today.

BA has suspended service as of now. Imagine the cost of decontaminating a place if ONE of the passengers that was on it later tests positive.
Or heaven forbid urps or worse while a passenger.
