yes you may have been exposed to fecal contaminants but they will not automatically jump inside your body through intact skin or through your clothing. since you cannot change your clothes or belt then just thoroughly wash your hands and avoid touching your eyes nose and mouth until you can change your clothing. this may be the best you can do right now short of a shower and buying new clothing over your lunch hour.
i accidentally sat on a toilet that had fecal matter on the front of the bowl and under the seat. should i be worried? . it was in a public toilet. the seat itself looked clean but i noticed too late that there was stuff along the front of the toilet where my pants or belt could have touched. i feel so gross but i can't go home and change. should i be worried that i'm covered in someone else's diseased germs?
