This guy caught it while in africa, he has not been referred to as a doc or othe health care provder. To say that ebola absolutely only transmits with close blood bodily fluid secretion is BS. That may be the clinical definition, but 20k+ cases say otherwise.
Understand the context here, yes... but certainly not enough to say that since he isn't a medical worker he wasn't exposed to blood or body fluids. Lots, lots, lots, LOTS of people in direct or indirect contact with a patient can easily be exposed to blood and/or bodily fluids. Simply a person wiping their nose and touching a doorhandle at a supermarket, bathroom, restaurant, rental car, bus or terminal, etc... could transmit it. I'm not sure 100% what you're getting at, but I don't think there's anywhere near enough evidence to suggest airborne transmission at this point in time.
Should we try to plan for worst-case scenario? Sure... but I wouldn't be too quick to start handing out masks to the general public or anything like that, yet.
