Frequently, a fever is the only symptom of a urinary tract infection in a toddler, according to BabyCenter. Other possible symptoms include foul-smelling, cloudy and/or bloody urine, loss of appetite, irritability, crying for no apparent reason, toileting accidents in children who are toilet trained and a frequent need to urinate.
BabyCenter explains that while UTIs are easily treated with antibiotics, permanent kidney damage or kidney failure can occur if the infection remains untreated. UTIs are often caused by E. coli bacteria from the rectum entering the urinary tract via the urethra, notes KidsHealth. Because a girl has a shorter urethra that is closer to the rectum, girls are more likely than boys to experience UTIs.
