There are many ways the approach and treatment to this and other diseases will be different in the future. However at the present this outbreak of Ebola will run its natural course the way prior outbreaks have done. It is a poor man’s disease since it is spread by the direct contact with the secretions of infected humans. Poor hygiene, close living and sleeping quarters and inadequate sanitation are the culprits. It is not likely to spread to first world nations in an endemic fashion.
Many of the people who are exposed never become deathly ill and some may not even notice symptoms. That is one of the insidious things about this bug.
People ignore the handrails, door handles, elevator buttons, and myriad other mutual and public contact surfaces the virus can be transmitted to--and from. From there, a scratch, rub your eye, touch your mouth, and you are infected.
The chief reason Ebola hasn't made it to the first world is geography. The reservoir species don't live here.
There, the infection may be attributed to transmission by contact with the body during funerals, but here, the infection may be passed on otherwise--something which could be masked by the funerary procedures there.
With a variable incubation period (2 to 21 days) attribution is something that may be a wee bit harder to nail down.
So, next time you use a handrail, watch to see if the person in front of you wiped sweat off their brow before touching it...because that is the level of awareness you will need to avoid it if it gets loose here, and even that is no guarantee.
