Hi all. Long story short...my husband has CF, a friend needed a place to stay so we offered her our spare room. We didn't think much of it at the time, but she gets sick (URIs)... often. She wasn't here a whole week before she got sick and now my husband is sick(he hasn't been sick in over a year). I'm sorry if I sound naive, but should we have her move out? My husband's health is priorty. Thank you for any advice.
