What is a urinary infection?

Bacteria in urine. A urinary tract infection (or uti) is the presence of bacteria in your urine. Urine is typically sterile and should have no bacteria. Typical UTI symptoms are: pain while urinating, urinating more frequently, fever, chills or back pain. Most cases are easily treated with a short course of antibiotics. Sometimes, bacteria is present without symptoms. These cases do not always need antibiotics.
Bacteria + symptoms. A urinary tract infection (UTI) is when there is bacterial overgrowth in the bladder or kidneys. Symptoms include burning with urination, sometimes blood in the urine, low back pain, or nausea. Women get utis much more than men. Antibiotics are usually effective in eliminating the symptoms. Utis are diagnosed with a urine dipstick test and a culture.
