#AskTheExpert Dear Dr. Radnyee is 5 month old. She had fever for 8 days. It was investigated in NICU with blood culture, urine culture, other blood tests reports. All reports were normal and nothing could be found. Temp was for 8 days and admitted to NICU on 8th day. But she is having fever frequently once-twice a month. T98 is given after 4 hours gap. After some days i.e. 2-3 days temp is decreased.Hygine is maintained. What could be the reason for frequent fever with 99 to 101 F?
