Urine

Naturally this is a health hazard , gloves should be worn , and the cleanup done
by a properly trained person.

We were told by a local nurse that there isn't any hazards.
Why do you suppose?

Well, she probably said that because healthy urine is sterile (no bacteria in it). Chances are very, very low that the urine would cause any problems for your children. But that doesn't mean that it was okay to make the boys clean it up ... I would think that someone at your child's school could get in a LOT of trouble for this if you raised the issue, perhaps fired!

There is a very minute chance that this urine could have blood in it, that that blood could have a dangerous pathogen (HIV, hepatitis), and that blood could have entered a cut on a boy's hand, creating an exposure issue. We are talking about extremely minute chances here. But that is why this could be a serious issue.

I would say that it's more likely that one of the boys might get an infection from bacteria that might have started growing in the urine while it was on the floor. Or from bacteria that was on the floor before the urine got there (floors are dirty places).

I would not worry about health consequences for my son if I were you. As long as he doesn't become visibly ill or wind up with infected sores on his hands, I think the chances are so remote that I wouldn't initiate any testing for disease. But I would be FURIOUS with his school for allowing that to happen!

Urine is a body fluid, and anyone who comes in contact with it in their job has the benefit of gloves, as per accepted universal health precautions. Someone at your son's school ought to be in bigger trouble than these boys!
