Don't fall for the media frenzy. Keep in mind they are making a lot of money off of all your panicked clicks.
This is certainly a tragedy for Africa. Just like the last 5 Ebola outbreaks were. This one's bigger but that mostly appears to be due to changes in culture and population than any change in the disease. But, by and large, Ebola is hard to transmit. It's prevalent in Africa because of poor sanitation. I've been to Africa (not this region, but others) The sanitation there is awful and even I, being careful, pretty much caught everything under the sun. There is no clean water to wash with. I bought bottled water and washed with that... didn't matter. The food is handled by dozens of people before you get it and there's no way to wash that either. The people that handled it clearly couldn't wash up properly either.
In regards to the medical facilities... they are woefully understaffed, under trained and short on equipment. The biggest difference the United States could make is to send over more of all of these. If the troops were sending are of this nature, it will certainly do a lot of good.
As far as a threat to us in the west though? No... short of it going airborne which, despite the soulless talking heads on TV are saying, is extremely unlikely. And if it were already airborne, we'd all already have it. Luckily, ultra deadly diseases like this burn out very quickly. It's hard to be virulent and deadly at the same time. The dead aren't that great at walking around and infecting people.
