That is going to be problematical, because about the only way to do that is to restrict movement. Beyond sealing borders with troops, and cordoning off areas, that will be tough to do--and even then, people will get through. It only takes one, early, asymptomatic to start another hotspot--they get sick when they get where they are going.
We're already seeing this affect air travel, with sick people on planes causing entire passenger compliments to be isolated until it can be determined whether or not the ill person had Ebola or was simply airsick.
The economic effects may drive things for a while, but failure to stop the disease from spreading more will cause even more serious economic problems later on.
With those problems come interrupted food supplies, lack of medical supplies (already a problem), and fuel, to name just a few things.
At that point those who die as an indirect result of the disease may outnumber those who die from it.
The quarantine of West Point in Monrovia is pointless of Rats eat the bodies of the Ebola killed and act as a co-living with human animal reserve of the disease.
Burning down West Point after the disease runs it course there would be even worse, as the Rats would flee into the rest of Monrovia.
The interaction of Ebola, Drug Addicts and Rats in densly populated areas in Western cities does not bear thinking...but we better hope _somebody_ is screaming about that to WHO and the CDC.
