Add Saudi Arabia to the list of possibles.
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.
If that is true, they’d better isolate ARAMCO personnel if that is not already too late.
