Well, I imagine the guy wasn't the sharpest knife in the drawer.
I'm sure he was scared out of his mind that he might have ebola. What to do? Get to the US for treatment. Fuck everyone else that would be encountered along the way, "they'll be fine".
Get to US, hang out a few days and see if one gets magically get better. No, now go to hospital. Tell only the basics for fear of being locked alone. Don't tell them that ebola might be staring them in the face. They aren't able to connect the dots, they give antibiotics, voila. It must not have been ebola! Thank goodness!
Return to family's apartment, stay sick, infect others. Wait two more days. okay, its really not getting better. Going back to hospital, but first let's get some vomit everywhere. It's so bad now that isolation is better than the black vomit. Apparently losing one's tongue is extremely painful.
