<s>[INST] Hi docter, my name is Peter. My nephew gets high fever 38 - 39 degree s and come and goes suddenly. So he goes on anti-biotics every now and then which is not good. He is 5 jears of age and this has been going on since he was 3. i have noticed for the first time (but i dont know for how long this has been going on) yesterday that his stool is dark grey and constipated. I mensioned this to my sister and it seems that it doesnt bother her that much? What do you think docter? [/INST] Hello, I feel that the kid is going through a viral illness and I agree with you that antibiotics are not necessary at all.95% of the fever in kids of this age group are viral and if the kid is active when the fever is touching the baseline, you need not worry about it at all, it will settle down by itself. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Sumanth Amperayani, Pediatrician, Pulmonology </s>
