All that the news folks say is that the old gal was sweating a good bit (it is summer and AC rarely if ever works well at the London airport), when she collapsed. Based on comments this morning...these tests don’t show any Ebola.
The problem I see coming is that you start to show a fever, cough, and sweat...and they want to shove you into a quarantine situation where you only have the flu currently, but will be around others who really have Ebola. So you will be infected....one way or another....by their stupidity.
I don’t see the civilized nations doing that, and giving non-Ebola people Ebola.
