Kidney infection in children is an alarming medical condition that can cause severe health issues if not treated properly. It is caused when bacteria enter the urinary tract and travel to the kidneys, leading to inflammation and pain. Early diagnosis and treatment are important for preventing long-term complications, such as kidney damage or scarring. Symptoms of a kidney infection in children include fever, abdominal pain, frequent urination, nausea and vomiting. It is important for parents to be aware of these signs so that they can seek medical attention if necessary.
