This was the abbreviation that I remember when I first saw it during clinicals I thought it was something really bad - at least something not appropriate. Well, come to find out it stands for fever of unknown origin.
Not that I am a doctor but that is what I am calling what AJ has been experiencing. He went from normal to 104.5 in a matter of 8 hours with a huge spike in the middle. He didn't have any other symptoms and seems to be back to normal today so who knows.
Must be a virus, right? (Or isn't that the catch all?)
So for now my son is FOUO.
