<s>[INST] Hi, I have a 3 year old with a temperature of 100 to 103, coughing, runny nose, vomiting, stomach hurts, red/puffy eyes, has been sick for 1 week, he has had tests for strep, flu and ear infection and all came back stating he was perfectly fine. Can you help me? [/INST] Hi...by what you say I feel that your kid is going through a viral illness. Usually it is a self limiting illness. All these non-specific symptoms are pointing towards a 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 -  </s>
