Just saw this now. Yes, you COULD ride next to someone and not catch it, and you CAN catch it - and MUCH easier than you think, and have been told endless times now. You've been showed word directly from WHO and the CDC quite a few times now, talking about a simple sneeze and such, and you still deny it. That person could have sneezed prior to you getting on the subway and they sit there silently. You simply touch the chair or post where they sneezed - and guess what? It only takes one droplet to transfer that disease to you. Now granted, sick ebola patient probably won't be on the subway - but it's YOU who is diminishing the virus and trying to claim that unless you physically touch someone you'll be fine, and that's 100% wrong.
From prior posts to you. Not going over the entire thing again, just enough to show that you're clueless as to how things travel via sneezing and how one can get such droplets - and it sure isn't only from kissing or wiping with his hand.
This was directly from the CDC as well:
