You can't isolate every person who gets a fever, and differentiating early symptoms from other more benign maladies becomes much more difficult.

Been looking but not finding a key factor--how long does the virus remain virulent when deposited on an environmental surface? The reinfection rate--the number of people, on average, infected by each person who gets the disease, is said to be 1-4. Stopping an epidemic from expanding requires getting it below 1, eliminating a disease requires getting it, ultimately, to zero.
Ebola is shed in the bodily fluids of persons with the active disease. It then must come in contact with a skin break, or the mucous of a body orifice, to infect another. This is for the good--this makes for a much lower reinfection rate than with airborne respiratory diseases, where it may be as high as 17 or so. Of course, the bad news is what happens when you are infected. In many people, the body is never able to mount an effective immune defense. This is why the death rate is around 50%, even with good hospital care.
In areas where the disease is in the population, I can see folks adopting the Japanese habit of wearing face masks around. Not to keep out airborne pathogens, but to keep one's hands out of the mouth and nose. That, and being very cautious in dealing with any person with flu-like symptoms in an outbreak area, should be enough.
But we may have trouble before the necessary practices become widespread.
