Hey everyone, I'm looking for your opinions or advice.

Last week I accepted a promotion at work. My new position will require me to work in an office more than my current role. (I was previously a field-based sales rep, I'm moving to a marketing/PR role.) I will divide my time between two offices- our divisional headquarters 3x a week and the remote sales office I currently am based out of.

Sounds great, right? It is, but my boss just told me that the desk I will use in the sales office 2x a week will also be used by another employee. He won't use my office very often, but I'm a little nervous that he could come in and use my desk while sick/contagious, and I wouldn't know it because I won't be there everyday. I usually clean off the bottom of my laptop after work (I set it on bar tables, etc- yuck) so as long as I do that and don't eat off of my desk, I should be okay, right? (He'll have to share my desk because our remote office is tiny.)

I probably won't think about this during the summer, but I KNOW it will be on my mind eventually. He's really good friends with another co-worker of ours who has gotten very ill with a virus every year I've known him. Any advice/tips?
