Hello. Welcome to HCM. Your child has high grade fever along with loaded pus cells. The child has severe urinary tract infection and needs immediate antibiotic therapy. If the child is a female, the urinary infections can be explained as they are commoner when compared to males due to short urethra. If male, generally, urinary infection is not very common, though it can occur. In future, please prevent infection by maintaining proper hygiene and avoiding unnoticed mechanical injury. It is very important to avoid stool contamination of urethral region in females. Take care.
