Same question. Even if "viable" means "infectious," the virus evidently can only get on that surface from a very sick person or a person who's just come into contact with one, and has touched the surface with the virus on his skin.

Ebola is not a very new disease. It has been studied for nearly 40 years.

You are far more likely to be killed by a bus or a handgun or lightning in America than by Ebola.

For now, anyway.
