[|Human|] My son is 3 years old and has had a fever off and on since yesterday. I first noticed it at 6am when he got up. I gave him Tylenol and it cam down slightly but always goes back up. Today it spiked to 104.5 in his ear and 104 under his arm. He has a slight cough and sounds a little congested, but that s his only other symptom. He was recently around some family members that were sick, but they were better within a day or two. Is there anything that the doctor can do if I take him, or should I let this run its course?
[|AI|]  Hello, I will explain to you how a viral illness behaves so that you can be more confident please. 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 to 7 days. So, do not worry about duration if the kid is active. Hope I have answered your query. Let me know if I can assist you further.
