<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 4 year old has run a fever varying from 99.5 to 103 for a week. Two days ago the doctor said it was probably viral, but it should clear up. I was under the impression viruses lasted many five days. He has no other symptoms besides heavy night sweats.  <response>: Hi... If your kid is normal in between fever episodes in a single day... I dont think you should worry. Danger signs include breathlessness rash low urine output seizures unconsciousness blood in motion. Dont worry if these are not there the kid is active. But with 1 week fever, I wouldnt still be considering viral. I would do a blood culture and basic blood workup and start on antibiotic like Definite which I would prefer in consideration to typhoid fever. Regards -
