Does anyone with a family member with cf have any experience with cellulitis?

My husband and I both have cellulitis in our leg, it is caused by staph or strep b infecting the skin...I also breastfeed and have had mastitis 3 times in the last 2 months. We are very clean people, we take care of our selves and have a clean home. As I have posted in my last message my daughter has been showing signs of having cf and will be having a sweat test on the 28th. I know people with Cf harbor bacteria in their mucus and I am wondering if this could be causing the skin infections and seemingly constant viral infections in our home. Has anyone had this experience?
