Hi. I just sat on a bus seat saturated with urine and it soaked through my jeans and underwear. Should I be worried about any disease transmission?!

Human urine contact. So sorry you had such a bad experience. It is unusual to contract disease from human urine. One possibility is cytomegalovirus or CMV, which can be mostly asymptomatic, give a mono-type syndrome, but is mostly dangerous to fetuses of woman not previously infected. Animal urine, on the other hand, can cause leptospirosis among other diseases.
