I have an almost 6 year old daughter who over the last few years has had numerous high fevers
with a high white blood cell count
with no other symptoms of signs of
infection. March 2009 she had a fever that went from 103.2 to 108 in less than 15 minutes. She was hospitalized for 5 days and they never found anything. She has been checked for UTI. Everything is always negative. Any ideas of what could cause this would be helpful.
