I think you should do what you feel comfortable doing. I remember my bf being ill and then the next day he was feeling better. It was Valentine's day, and as much as I did NOT want to be near him with him being sick so soon beforehand, I didn't want to ruin our day, so he came over. We had dinner, he spent the night AND we even had our "intimate" time. I never caught it. I just washed my hands and tripled up on all of my supplements. I was scared to death but really glad I didn't let my phobia ruin the day for us!
