<s>[INST] My son Vigneshwaran Age 6 Years having fevr for the past 6 days. We are giving him Calpol 250 mg very 6 hours . The temperature varies between 102 - 104. If we stop the calpol , the temperatature more than 102. What could be the reason for this. Blood Results of Malria,Thypoid Flu are negative. [/INST] Hi....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 and playing around when there is no fever, it is probably viral illness and it doesn't require antibiotics at all. Once viral fever comes it will there for 4-7 days. So do not worry about duration if the kid is active.Regards - Dr. Sumanth </s>
