I thought to that once you got MRSA that the best course of treatment was IV antibiotics? It is worth at least asking a few questions anyway. Also it may be available in an injection to start off, followed by oral antibiotics. My feeling is that if it can spread even through a hospital or school, then how can you not disinfect yourself and your home. A can of Lysol and some antibacterial soap are very cheap precautions. Here are links for you to read.

"An ounce of Prevention is worth a Pound of Cure"
My little ones just came down with fever/runny noses etc...and my husband is on Chemo so to prevent him from getting sick I went as far as to spray their bed linens and pillows then stripping the bed, & washing everything every morning. I also spray the faucets, door knobs, light switches, and the toilet just to prevent the spread. It may be over kill, but it is the best I can do to keep everyone, and my home germ free. Did you ever read the back of a can of Lysol? Worth a few dollars.
I found that the "Crisp Linen" has the most pleasant smell.
