If you know the exact methods with which Ebola spreads, you would know that it would never, ever spread in the US. We're too civilized and have too good of an infrastructure mixed with the people being too intelligent. It's practically an STD. All you need to do to not catch Ebola is not kiss or have sex or get blood on you from someone who's infected. That's it! Oh, and don't handle their bodies with your bare hands. Oh, and maybe don't break into a quarantine zone and fucking free all the damn infected people. There isn't a terribly long incubation period either for ebola. Ask any doctor about the golden rule. Not airborne, not a problem. If it can live on surfaces, places can close, people can wash their hands, and you can alcohol the hell out of everything everywhere constantly for cheap.
It's really a shame Nigeria wasn't wiped out though. Pirates and scammers and their corrupt governments would be wiped out and their society could start over without all those problems. 50 years later they'd have a better economy than the last 100 years.
