[|Human|] my 15yrold grandson  has become  extremely thin over the past few months. he has become lethargic aand complains about not feeling well. He has had a fever and cough on and off and staggered and fell in a store.  At that point he was diagnosed with mono .Bloodwork showed he had been exposed to mono.  He still looks pale and tire easily.  He is also still very thin. Does he have active mono or is this maybe something else after all these months?
[|AI|]  Mono or infectious mononucleosis refers to a viral sore throat caused by a virus called Epstein Barr Virus. It is usually a self limiting condition and needs to be treated with gurgling with lukewarm water. Usually the condition resolves in 5-7 days but may occasionally take longer. It is very unlikely that he has been having active mono for last few months. This being thin, pale and weak is probably unrelated and needs further evaluation before the cause can be commented upon. Lethargy necessitates such an investigation. Treatment will depend upon the cause.
