Causes and Symptoms
A urinary tract infection (UTI) refers to an infection in the urinary system caused by microbes.
Typically, this condition is caused by bacteria, but there are some cases wherein the infection is caused by fungi or viruses. It can happen in any part of the urinary system, which consists of the urethra, ureters, bladder and kidneys.
UTI can affect the lower tract consisting of the urethra and bladder or the upper tract consisting of the kidneys and ureters. While this infection rarely affects the upper tract, it is also more severe compared to lower tract UTIs.
