[Interesting that the virus is not being reported at all in places like North Korea, Russia, Syria, Iran and Eastern bloc countries.]
I expect the Chinese diaspora and trade links are thin on the ground in those countries.
Likely those countries will not let anyone in who has been to China. I read that North Korea will not allow them and that Mexico will not allow its citizens who have been to Wuhan to return to Mexico. They were told to shelter in place.
