<s>[INST] Dear Sir, Our Kid, age - 9 yrs suffering from severe fever since last 15 days. Consulated several doctors but no use. 4 days back we have joined him in children speciality hospital. 2 xrays, untrasound scanning as wel as blood test 5 times was done but they are unable to detect the problem. The fever is mostly in the night timings and is reaching about 102 degrees and in the day time it is normal. He is feeling too ill while fever and is feeling normal when he is not with fever. Doctors are expecting doubt that there is blood infection and they observed puss in blood and they are not sure about it. even with this fever there is no change in weight, urine and motion of the kid. all are normal. Kindly suggest the problem in him and suggest suitable treatment. Kindly help us and do the needful. Yours Sincerely, K. Subash Reddy [/INST] It's bad to hear that your kid is suffering from fever from last 15 days. As u mentioned that all blood reports are normal and child is active when fever is not present in mornings, It suggests most probably a viral fever. But simple viral fever doe snot usually last 15 days, U didn't mentioned your child weight, because IN TUBERCULOSIS child weight will be low, cough, Not takes adequate food & most importantly child will have EVENING RISE OF TEMPARATUREkindly do MANTA TEST to your kid which detects TUBERCULOSIS.  TYPHOID is another fever where u will get 15 days fever, but child looks ill. </s>
