What might be causing unexplained fevers in a 6 year old? There is no other symtom of illness, and the child feels well. But a fever of a 104 scares me. He has just started kindergarten. And the day before he took sick with a fever he attended a birthday party for another 6-year-old.
Hello.  I just read through your question. The mist common diagnosis is a harmless viral illness. These typically resolve on their own after a few days. However, if the fever persists beyond 2-3 days, I recommend consulting with your doctor.
