You're not making sense.
If he knew he he'd been exposed to Ebola, and now found himself safely in the Land of the Free, why did he not object when Dr Feelgood at Texas Health Presbyterian sent him on his way with a worse than useless antibiotic prescription?
It's obvious that either he didn't know or he was in deep denial as to his predicament.
He knew he’d been exposed and he knew he was exhibiting symptoms, so he fled to the US. Once there, he attempted to get himself admitted to hospital. But, he believed the high priests of medicine rather than his own lying eyes and went home with painkillers, relieved that he’d been told what he desperately wanted to hear. Then, he continued to sicken.
“It’s obvious that either he didn’t know or he was in deep denial as to his predicament.”
Or he was both a liar and dangerously stupid.
You are making the ignorant assumption that he is but an innocent victim here, and you are not looking at the situation rationally.
I make perfect sense, in the real world, which is the one we are all currently living in.
