Hello, What your daughter is having is an Epstein-Barr virus infection or infectious mononucleosis. This is a self-limiting chronic viral infection, but ultimately she will develop resistance to it. Regarding the urticaria Rash usually, it will come and go, and you need not worry about this as this is an allergic phenomenon and most probably and related to the infectious mononucleosis, please. Round the clock antihistamine for a period of seven days will be helpful. But if this is recurrent phenomena then hereditary angioedema needs to be considered. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
