 [ Symptoms ] how would an emergency aid physician handle a 100 degree fever in a three year old so i am a novelist trying to figure out a hospital scene in my latest work my character has just taken her son to the hospital because they both have fevers of over 100 she is at 100 her three year old is at 103 and she is basically in a panic  they both have mono the mother had it first and transferred it to her son unknowingly and i have done research to find how a doctor would treat this what i need to know is how the physician would break the fever  thank you very much [ Disease ] a few problems with your story 1 fever is harmless both the 103 and the 100 it is unlikely that an experienced physician would do anything fever is more beneficial and does not need to be treated at all 2 mono is a virus and it is not treatable either
