Has he been in the hospital? It seems to be one that can be spread there. He's still really little... if he had any invasive procedures after birth due to complications of his cf he also could have contracted it then. It used to be considered a 'harmless' bug but was eventually found to be an opportunistic pathogen that can cause various types of infection, including that of the respiratory tract.

This is one of the most important reasons to stay in touch with the cf center whenever our little ones get sick. When they culture our kids, not only do they want to determine what they are growing, but they then figure out what abx it is sensitive to- so when they get sick, they know what to prescribe. The ped doesn't, in most cases, have the benefit of this information.
I hope tomorrow's appt goes well and they can get little Sam feeling better really soon. <img src="i/expressions/heart.gif" border="0">
