Marissa has had MRSA for a couple of years now. The clinic doesn't treat her for it. I'm not happy about it. I wish they would get rid of it. My understanding is that as long as it isn't causing a problem they are going to let it be. (Not exactly the way I like to play, I prefer offensive to defensive manuevers, but I don't have the degrees).
Kids in my daughter's school who do not have CF have recently been found to be MRSA carriers. The local schools had a pretty big outbreak of it last year. Most of the local doctor offices have notices up right when you walk in warning what a MRSA skin infection might look like and instructing you to tell right away if you think you might have one.
There is some info out there that suggests being infected with MRSA will cause more hospitalizations/sicknesses. Marissa has only been hospitalized twice in two years, 2 years ago for a stubborn ear infection, and last February for DIOS. So far it has not caused any infections, but her FEV1 and Peak Flow are dropping now without her culturing anything else.
I hope they get rid of it for you.
Good Luck!
Terry
