RSV

I'm seeking some understanding about RSV and where it comes from. I used to suffer from this virus and now it seems my youngest grandson has it as well. I have researched its background but the one thing that is not stated is where it comes from or should I say how it is started other than it is spread. Is it possible that even though I no longer suffer from it's effects that I may still be a carrier? I would hate to think that he got it from me. Chase has CF but has never been diagnosed with RSV and he lives with me. I am concerned about Paxton but not overly worried as I know how to over come the effects of this virus of his given time. My granddaughter has also shown some real respiratory problems of late having what the doc is calling severe bronchitis 4 times in as many months. Again is it possible that she too has RSV just not diagnosed. To many similarities to close together for me to just dismiss them. Larina is to be tested later this month for CF as she is being suspect of having it although she does not have the same father as her brother.
