Which does make the site Natural News linked to confusing if not downright contradictory, because sneezing is in the section on germs, while it's not mentioned in the ebola section, so how is a layman supposed to know that the very picture in the "germs, not ebola" section is one way ebola could be transmitted. While I feel the CDC does indeed have specific meanings attached to their terms, I see absolutely no effort to convey that information, at least not in this particular link Natural News has seized upon. Maybe their headline should have screamed "CDC Writers Just As Incompetent As Everyone Else."
ETA: Iris, I agree entirely with what you posited somewhere else: government mostly isn't lying on purpose, it's just incompetent and usually tries to mask it with a lot of meaningless nonsense. I'm always amused to hear that "They" know everything there is to know about climate change, or for that matter, the intricacies of our economic policy. "Unintended Consequences" could be their epitaph.
