There is no vaccine, no standard treatment, and the origin of the virus remains unknown. Ebola can't be also be treated by killing the virus.
You're a bit too optimistic... :/
Fortunately, Ebola is a relatively difficult disease to transmit. While all bodily fluids become infectious - it is not like the flu in that it is not an airborne disease.
Every other outbreak of Ebola has burned itself out. The virus can take about three weeks to 'burn' through a victim, and Africa's cultural 'lockdown' responses to disease outbreaks are generally sufficient to prevent the spread of the disease.
Where things get into trouble is when patients go to hospitals. Even in relatively modern hospitals - staff are highly likely to become infected and to be primary vectors for infection (although patient care standards are higher, so patient-to-patient transmissions should be lower). In most of Africa, however, the standards of care are fairly low, and most of the victims are people who were in a hospital or who attempted to care for loved ones.
Generally speaking, however, Ebola is a Level 4 biological contagion. It is one of the most feared viruses to work with because accidental exposure is essentially a death sentence to the worker. The Zaire strain of the virus has something like a 95-98% mortality rate among documented cases.
Although the virus does have a survival rate. For whatever reason, some people who contract it are able to fight off the viral infection. A major factor is the standard of health care received (and many of the mortality rates are likely very high simply because of the lower standards of care in Africa - as well as only being diagnosed later in the stages of the disease).
Since it requires direct contact with human bodily fluids and has such a nightmarish hemorrhagic process - it ends up inhibiting its own ability to spread/infect. The people most likely to infect you will have sagging faces, 'bloody stars' on their skin, and generally look like someone you should avoid if you value your health. You don't even have to know about ebola or an outbreak of it for your instincts to tell you that something's not quite right.
On the other hand - Small Pox would pretty much crush society if it got out despite it having a much lower incidence of mortality.
