Tell me how do you catch a urinary tract infection?

More than one way: Bacteria may reach urinary bladder by traveling up the urethra, especially in women. Wipe front to back to reduce risk. Damage to urethra, e.G with sex may predispose; empty your bladder after sex; drink plenty of water to flush the system. Bacterial may seed the kidney from blood in both men and women. Presence of stones and obstruction to flow of urine also predispose to infection.
