Could a splash from toilet water cause diseases?
Any liquid, whether it is toilet water, tap water, bottled water, juice, soda, milk, soap, etc, will contain (unless boiling/burning) millions of bacterial microbes. You have more of a chance of getting sick by putting your hand in your mouth. To not scare you, many of these microbes are harmless! In fact your body needs bacteria to break down food, which is just one of the many needs your body has for bacteria. Just to let you in on a little something, we all have probably done what you did, I did, and I was fine.
