Strains don't mean it changes its overall nature. Ebola is an enveloped virus. Meaning it can change rapidly once its inside the host, evading the immune system (its high death rate), but it is not transmitted as easily as non-enveloped viruses. Non-enveloped viruses have a protein coat but no envelope, and are not so easily degraded outside the body.
This is why it is extremely hard for an enveloped virus to suddenly lose its envelope and develop a protein coat to become nonenveloped. It would be like asking you to spontaneously grow another stomach because you ate too much.

Makes sound scientific sense; I just don't think we know enough yet.
That said, a physician friend shared this non-alarmist article earlier.
It's a good take on ebola in the US.
Don’t panic over Ebola in America

all this is assuming the mutations are occurring in a natural state unmolested. now entertain your conspiratorial side for a second and ask yourself what if this very mutation were helped along in a lab at, say, Ft Detrick.
