I can see why you would be scared. I would not like that either. The coronavirus is freaking me out in a way that these other big health scares have not and I can't tell if it's paranoia or prudence. It is possible for you to protect yourself from coronavirus (if he has it) by staying away from him, disinfecting high touch areas like fridge handles, doorknobs, washing your hands, and not touching your face. There is also a really good chance that he does not have it. He may have a cold or allergies - it's getting to be that time of year. Fingers crossed it's just a cold and you don't catch that either.
