I agree and what you said is exactly the point that I've been trying to make. I feel compassion for my coworker because I can't imagine how miserable it would be to always be sick, but at the same time, what about the rest of us? I'm concerned about her health, but I'm also concerned about mine as well. It's one thing for her to keep coming into work sick, but she could at least try and be more careful. It doesn't take much common sense to realize that coughing and spitting into a trash can is inappropriate and absolutely disgusting.
