Well I guess I'll chime in, as the resident skeptic.
Every time there is a new disease in the news, people think it's airborne and that's being covered up in a conspiracy. Happened with HIV too.
Airborne is not the same as droplets. That means it's carried on dust in the air and you don't even have to be near an infected person to get it. If a disease is truly airborne, it spreads quickly. Ebola has been identified for about 40 years.
And then there's droplets, which is not the same thing as airborne. You need to be near a person who coughs or sneezes a droplet of infected liquid. This is how TB is spread, for example. CDC isn't hiding the fact that droplet contamination can occur on surfaces; in fact, they are publicizing it.
Is it possible an organism could evolve to be airborne? Possible, perhaps, but that hasn't happened. Many diseases have been around a lot longer and they haven't, either.
It is terrible that this disease has such a high mortality rate, but it's great that it's not airborne.
In all my years of working in healthcare, whenever a healthcare worker has gotten a non-airborne infection from a patient, there was a break in universal precautions, or equipment failure.
This stuff is not unknown--we do know a lot about viruses.
