 [ Symptoms ] what infection can cause a urine in a bottle  hi expert  i know its weird question but it is urgent for one my frnd he was staying a 3rd floor in hostel so in nights he collected urine in a bottle and uses the same bottle for next night with the same urine when i went to his room unfortunately i saw that bottle and came to know abt his laziness but i am confused whether he will get any infections from that bottle any precautionary treatment can be made  ps he using like this for only last 3 days [ Disease ] he is truly a lazy man but no one will likely get any diseases from his odd bathroom habits urine is considered sterile unless the person has a bladder or kidney problem or a sexually transmitted disease so germs will not jump out of that bottle and cause any type of illness in you or him disgusting habit perhaps unless there is a major snow storm or other compelling reason i see no reason why this person cannot just get up and go to the proper toilet facilities like everyone else well at least he is not peeing out of a window or confusing his urine collection bottle with a water bottle
