How could one avoid ebola virus?

Don't go where it is: The first and most important risk factor for Ebola is: Travel to west Africa. It is really that simple. You can't catch it by casual contact and it is not thought to be airborne. Therefore, staying away from areas where Ebola is endemic (common in that area) is the surest way to avoid it.

Isolate contaminated: Avoid contact with body fluids. However, not likely you will get ebola virus unless you are in an area where ebola is edemic

Ebola: Avoid areas with an Ebola outbreak. This virus is not air borne so less chance of spreading . Check out the cdc website for more info.
