I had a friend with CF and I was with him every Sunday, Wednesday, and Thursday. we were just careful like we always stayed at least 3 feet away from each other and if one of us was sick we would try to stay away from each other. My point is I don't think it really matters as long as you're both healthy.Just wondering how people feel about mixing with other poeple with CF. I have a lot of CF friends,, one that lives just down the road from me and we meet up all the time and hang out. I don't care about the infection risks,, and neither does he..
