Nigeria has a very low numbers of Ebola cases ... not likely an Ebola infection... in my opinion.
I live in Thailand - not far from Phuket... and I believe from what I know of Thai Immigration ... should this case somehow turn out to Ebola... Thai visas granted to African countries will cease forthwith... Not just West African Countries...
Thailand has very strict immigration protocols... Wish the concept would catch on in the U.S. Government.
I lived in NE Thailand for 2 1/2yrs a while back, and I agree with your assessment of Thai immigration. They don’t screw around. People who have never been to Thailand do not realize that some Thai hospitals would put American ones to shame.
