My 5 year old daughter has been running a temp on and off for the last week, but since yesterday it has reached as high as 102 to 103.6. She complains of headaches and chills. Over the counter medication does bring down the fever a bit but not completely. She also still has her appetite...now vomiting or diahrea. She received her booster vaccinations almost 2 weeks ago and only recently been getting ate up by mosquitoes.
Thanks for asking gone through your question, your 5-year daughter having fever with chills since last week.  I was your treating pediatrician, then I would examine and investigate her for cause of fever.  Common cause of high grade fever with chills is malaria, urinary tract infection(UTI), So I order Blood test for malaria, and urine test for detect infection, I also order for blood culture to detect bacteria in blood that may because of fever.  So you should consult doctor for proper investigation hope I answer your query
