preemie question

My son was born at 35 eeeks he came home a week later besides that I was wondering because they told me to be extremely careful about who we take him around because he also pooped in my stomach and has breathing problems and still has some problems. Is he aloud around people who just got out of surgery? They told me he isn't even aloud around people who has diarrhea and after surgery you usually have diarrhea from all the fluids and stuff. I'm just scared because he has got sick and had episodes of me waking up to him not breathing and I would feel horrible if this lady got him sick
