I, too have MRSA and I looked online to find information about it when I was first diagnosed. You may check w/ your doctor, but from what I can gather, there are 2 kinds of MRSA. One is the kind that is spread in locker rooms w/ sports teams and I think it is a skin type staph infection. The other is the staph that we CFers can culture in our lungs. The school has probably heard about the locker room spread MRSA and doesn't understand that your son has MRSA in his lungs & it can't be spread to others unless their immune system is compromised (i.e. undergoing chemo, have CF or other immune deficient disease). They probably think he has the type of MRSA that has become a problem in locker rooms across the country. Ask your Dr first to make sure that your sons MRSA is not the locker room variety and then explain to the school authorities that your son has MRSA in his lungs, not the skin type (if this is actually what the Dr confirmed). I hope this has helped & not confused you.<img src="i/expressions/face-icon-small-confused.gif" border="0">
