You do realize now that there is many unknowns now about who that patient was in contact with for several days before symptoms appeared, where he touched/sneezed/etc prior of being isolation? It's different case then those doctors that had strict quarantine before entrance. No one person is not outbreak but patient zero compromising the general public will be for a disease we don't fully understand.
No one can predict the future but again, you're jumping the gun here as no outbreak yet. Also there are factors that we still need to consider such as US hospitals resources vs. W. Africa where the health workers sometimes won't even go near the ebola patients for fear that they will contract it.
"Cure"? There is no such thing for this virus yet. There are limited experimental vaccinations from various pharmasuticals such as Zmapp that had limited success, but not 100% either since a Spain Priest with ebola died even with it and even then it's a question of how strong your immune system is. Other avenues was blood tests off ebola survivors that had natural immunity, but could still be potential carriers.
Not much comfort either with "harder to catch then the flu" when trained medical staff that took every precaution still caught the virus in Africa. This is also ignoring the potential of having 5,000 US Soldiers in Africa that can potentially carry the virus.
There's no point worrying yourself over something we have no control over. I'm a medical student, working in the emergency department this month no less, and I will continue to serve patients as I'm not afraid. Always wash your hands (the most effective way to prevent this and most other viral transmissions) and hope for the best I guess.
