Hello Vivek, thank you for posting your question.
The clinical diagnosis of any
fever is based on a few principles. Firsly we enquire about the associated symptoms the child had with fever. Apart from that the extent and pattern of fever, whether it was associated with
chills or came at any particular time of the day etc. These details would help us know what would probably have caused the fever and based on that investigations are usually ordered.
In case of Athrv, as you informed he was initially treated for a
stomach infection, then for
pneumonia and finally for
urinary tract infection. In such a situation you have two possibilities. Either he had 3 different kinds of infection which presented with fever over 2 months, in which case his fever should have subsided each time with the medication, he should have felt better and then again fallen sick with a new infection.
If that is not the case then his fever could probably be attributed to a single cause , with the other two being misdiagnosis. In such cases investigations could give support and clue as to what the exact cause of fever is.
Mucosal irregularities in
urinary bladder is a very non specific finding and the diagnosis of a urinary tract infection should never solely be based on that. Associated symptoms of pain or difficulty in urination along with a positive urine culture is required for diagnosis.
If you could provide any more information regarding what his urine culture report was, or what his associated symptoms were, then it would be much easier for me to provide you any further guidance.
