Dear Coworker -- Stay home when you're sick. And if you insist on coming in to work sick, it would be nice if you didn't chose that particular day to hang around my work area, talking to yourself, constantly clearing the thick phlegm from your throat, and sneezing. I'm seeking Divine Intervention in co-existing gracefully with your Type A, OCD personality (and I thought your gum cracking/snapping/bubble blowing and negative comments were bad.....). When you're sick and spreading germs, it's a greater challenge.
