Bladder infection (cystitis) is the most common infection of the
lower urinary tract. Bladder infection is usually caused by bacteria that get
into the bladder by traveling up the urethra.
Bladder infections are more common in girls and women than in boys and men.
Symptoms of a bladder infection can range from mild to severe, and
Symptoms of a bladder infection in children depend on the age of
the child. A very young child with a bladder infection may only have a fever. Or he or she may cry when urinating or may vomit. It may be hard to know if the symptoms are a result of
urinary problems or another cause.
If untreated, bladder infections can lead to more serious kidney
infections that cause fever and lower back (flank) pain, and may damage the
kidneys. Bladder infections are treated with antibiotics.
