Our Grandson, age of 16 had Typoid fever about 3 weeks ago. Now since January 29th, he has been running temperature of 101 to 103 morning and evening.  He has blood tests done for several things, but to no avail.Going to see a doctor of infectious diseases on Thursday the 11th.  They have ruled out flu and so far not bacteria infection.  Will have results of another blood culture again tomorrow.
Dear I can understand your concern. Continuous running of fever is suggestive of some infection that need to be searched and adequately treated. For finding the focus of fever we need complete history and examination. Sussex whether he has any sore throat nasal discharge cough chest pain etc. Or he has any burning during this or increased frequency of urination Or he has any pain abdomen. Every organ system needs to be assessed. If needed certain blood taste and X-ray may be done. So in my opinion you should consult your physician for further evaluation and management. Hope this will help you.  If you have any other concerns please feel free to message me.  Thanks for contacting Chat Doctor.
