how would you handle this?

I am 38w4d and have been getting contractions pretty often throughout the past few days; so at this point the baby can come anytime now. My MIL who lives about 14 hours from us has plans of coming down as soon as I went into labor and staying at our house for a week or two, HOWEVER we just found out she has full blown pneumonia. She's been to the doctor and gotten meds, and says after two days she won't be contagious anymore and that won't stop her from meeting her first grandchild. I don't know if I'm just being ridiculous because I'm really not that fond of her, but I don't want her anywhere near my newborn knowing she just had pneumonia, even if she supposedly isn't contagious anymore. How long would you have someone sick wait before they came in contact with your newborn? My husband is completely on board with me, but she isn't listening to us at all.
