I don't think I have ever in my life have blood from anyone splashed in my eyes or mouth. That's how people's imagination goes wrong and increases their perception of risk: Blood getting splashed in your eyes and mouth is a powerful image, and something that you wouldn't like, Ebola or not. Since the image is so powerful, your brain thinks it could easily happen and needs to be avoided, and _then_ you combine it with Ebola. (Medical staff can avoid this risk quite easily).
If you've ever shaken someone's hand, and felt the moisture of their sweat, that's a body fluid. If ebola strikes the U.S., it will be important for people to realise what body fluids are.
