My son is 15. He has had fever for 6 days. The fever has ranged from none to 104.5, with most days around 102. My doctor says its a virus and to wait it out.  He is extremely weak. No symptoms other than weakness and loss of appetite. The doctor has done a flu test, strep test, and blood test which revealed a high blood cell count, but thats all.  Advice?
Hi... Thank you for consulting in Chat Doctor. Appetite loss and weakness or malaise is very common in the recovery or convalescence period of viral illness. Fever of few days without any localizing signs could as well a viral illness. Usually rather than fever, what is more important is the activity of the child, in between 2 fever episodes on the same day. If the kid is active when there is no fever, it is probably viral illness only. Once viral fever comes it will there for 4-7 days. So do not worry about duration if the kid is active. Hope my answer was helpful for you. I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome.
