Thanks for writing to health care magic.
I can understand your concern.
If a child is diagnosed of UTI then proper antibiotic course should be taken. If the fever
persists even after completion of the antibiotic course then you should consider antibiotic resistant organism and the antibiotic should be changed according to culture and sensitivity report.
Continue to ask further queries as required.
Hope this helps.
