Cough Cough!!!

My company recently hired a couple of clerks. They help around with little things such as photocopying, filing, running errands etc. One was given a seat beside my table because it was vacant. I do not have any beef with this guy until this morning that is. The guy called in sick yesterday but turned in for work this morning. That's where my problem begins. He's down with cough. And now, he's constantly coughing with his mouth open. It's disgusting and each time it happens, I'm reminded of all the germs and bacteria he's sending flying all over the room. Think my throat is beginning to itch too. Help.
