[|AI|]  Hi...by what you say I feel that your kid might be having a recurrent viral illness. I will explain to you how a viral illness behaves so that you can be more confident. 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 -
